This clean energy is now used for vehicle fuelling, showcasing a model for reducing waste and carbon emissions. The project highlights the potential of converting organic industrial waste into sustainable energy solutions.
Various international projects have explored recycling organic waste into biogas and organic fertilizer. While these initiatives present significant opportunities for renewable energy production and sustainable agriculture, challenges such as technology adoption, financing, and regulatory hurdles are still remaining. Projects that offer insights into overcoming these barriers and scaling biogas solutions can be termed as successful.
Another case study talks on how optimizing stirring technology is crucial for increasing biogas yields and improving the efficiency of biogas plants. Proper mixing ensures uniform digestion and maximizes the breakdown of organic matter. Advances in stirring systems help reduce energy consumption and enhance overall biogas production, making plants more cost-effective and sustainable.
Achieving a net-zero future depends on transformative changes in finance and sustainability accounting. This shift involves integrating Environmental, Social, and Governance (ESG) criteria into investment strategies, enabling more sustainable business practices.

IBA's Commitment to Advancing Industry Prospects for Biogas/Bio-CNG
- Period: July '24 - September '24
IBA hosted 7th General Assembly:
IBA held its 7th General Assembly on 27th September 2024. The General Assembly was held virtually through MS Teams, and several of its members participated. The annual event provides members with valuable insights into the association's past activities and roadmap for the future. The live recordings of the event are kept on IBA’s website and online channel for future reference. Participating IBA members from diverse backgrounds made the Annual Assembly even more appealing by brewing discussions, and fostering a collaborative environment for sharing ideas. The Annual Assembly plays a key role in ensur-
ing the inclusivity of the biogas fraternity in the modus operandi of the Association.
IBA recommends Govt. to rope in PSU firms to ensure Fermented Organic Manure (FOM) off-take:
Indian Biogas Association (IBA) has suggested that the government should rope in stateowned fertiliser marketing companies to ensure off-take of fermented organic manure to boost the sector. Indian Biogas Association has studied that there are around 97 functional CBG (Compressed BioGas) plants with an average production of 7.5 TPD (tonne per day) CBG and 30 TPD FOM per plant. Also, there is an estimated pro-
duction of the FOM of around 1 million tonnes per annum, with a higher potential of up to 7 million tonnes per annum.
As per Fertilizer Management System portal data for the year 2021-22 alone, total fertilizer consumed in the country was 63.6 MMT, with major states being Uttar Pradesh, Maharashtra, Madhya Pradesh, Karnataka, Punjab, Rajasthan and Gujarat. With the fertilizer import bill of USD 12 billion for 2020-21 poised to go up to USD 20 billion by 2030, the Indian Biogas Association highlighted that the fermented organic manure market can reduce the fertilizer imports by at least USD 1.5 billion given the envisaged 5000 plants under SATAT (Sustainable Alternative Towards Affordable Transportation) are reached.
IBA also suggested that the Ministry of Agriculture, through its agricultural extension services, including the Krishi Vikas Kendras (KVKs) under ICAR, should intensify efforts to promote the use of FOM on farmland. Agriculture universities and KVKs should conduct field demonstrations, utilising FOM to enhance its popularity among farmers, with specific targets assigned to the KVKs,
Also, State and district-level government bodies must organise and implement awareness and training programmes for agricultural personnel and farmers in a structured, planned, and timely manner.
Successful organization of Bio-Energy Pavilion, 2024:
The Indian Biogas Association organized the "Bio-Energy Pavilion 2024" at the Renewable Energy India Expo, India Expo Mart in Greater Noida on October 3, 4, and 5, 2024. Barring the lockdown year during the pandemic, IBA has been organizing the bio-pavilion for the past 6 years, with each subsequent edition of the Bio-Energy Pavilion being bigger than the last one. This time around, the pavilion and conference are meant to raise awareness about the Bio-Energy sector and bring together corporates, entrepreneurs, academics, social organizations, lending institutions, and investors. The intended goal of the event has been to further bolster the scientific waste management practices, which are already supported by government programs like Swachh Bharat Mission, Sustainable Alternative Technology for Affordable Transportation (SATAT), Solid Waste Management Rules, CBG-Blending quotas, Organic Manure Promotion scheme, Pipeline Infrastructure Scheme, Biomass Aggregation scheme, etc.
The latest edition of Bio Energy Pavilion 2024 exceeded all expectations. With around 50 prominent Biogas and CBG-related companies and organizations exhibiting at the event, it served as a robust platform for industry players. The remarkable turnout of over 7000 trade visitors highlighted the growing interest and
Importance of biogas and CBG in the sustainable energy landscape. The accompanying International Bio-Energy Conference on the final day of the event was a focal point of knowledge sharing, featuring 30+ distinguished speakers.

It concluded with a closing address by Dr. A. R. Shukla, President of the Indian Biogas Association, followed by feedback collection from all participants.
Conference at RE-INVEST on Bioenergy organized by MNRE with IBA being the knowledge partner:
The Ministry of New and Re-
newable Energy [MNRE] hosted the fourth edition of their flagship event – RE INVEST between the 16th to 18th of September in Gandhi Nagar, Gujarat. The Indian Biogas Association has shown its remarkable presence at RE-Invest by moderating the session “Strategic Investment in Bioenergy – A Way for Sustainability” which focused on the role of global collaboration in bioenergy projects, bio-methanation co-benefits beyond energy, monetizing carbon credits in bioenergy enterprises, international best practices towards fostering the biomethane ecosystem, carbon capture and downstream utilization in bio methanation plants including further biogas valorisation possibilities and Financing instruments for de-risking large scale bioenergy projects. With IBA moderating the session, it was co-panelled by officials from the Ministry of New and Renewable Energy, Indian Renewable Energy Development Agency Limited, German Biogas Association, World Biogas Association, CKA and Topsoe.
IBA and SSS-NIBE jointly organize National hands-on training programme:
The Ministry of New and Renewable Energy (MNRE) has been supporting programmes for promoting biogas as a clean fuel for domestic cooking, off-grid and grid power generation and bioCNG for transport applications. Biogas generation from agriculture waste is also emerging
as a potential area not only for biogas generation but also for climate change concerns given recent environmental risks due to the burning of paddy straw in the farms of Haryana and Punjab states. In addition, recent studies showed algae as 3rd-generation biomass feedstock derived through wastewater treatment has the potential to integrate with biogas production. Thus, there is a strong need to take up research and development initiatives for technology development and demonstration to integrate biogas technology for biogas generation and up-gradation for heat and power applications and bio-fertilizer for sustainable energy and agriculture development. The Indian Biogas Association in collaboration with Sardar Swaran Singh National Institute of Bio-Energy organizes a National hands-on training Programme on Biogas Technology and its Implementation. The experts will be joining from R&D/ Academic/ Financing Institutions, Ministry and Industries for delivering lectures in the training programme.

Improving the Stock Value of CBG Units
As concerns about climate change and energy security grow, the potential for biogas as a key player in the energy market is increasingly recognized. However, to fully realize this potential, the prospective sentiments for the biogas industry must be improved which shall then lead to promoting investor confidence followed by increased allocation of Capital. Investors' confidence is buoyed by advancements in biogas technology, long-term government policies, and emphasis on environment sustainability initiatives like targeted reduction of
emissions and carbon footprints across the business fraternity. These elements shall collectively drive the stock valuation of CBG projects, making the biogas industry an attractive prospect for investors.
Such an anticipated scenario can only be achieved through a gradual reduction of some of the prevailing uncertainties or risks spanning the industry. Typically for biogas plants, these risks may include operational or technical failures, supply chain disruption, unstable policy regimes, and inappropriate financial management. Indeed, a lot of effort has already been put towards making the sector credible and lucrative but, as a continued saga of improvement, there lies room for some of the above-mentioned aspects to be further honed upon. Here is an attempt to figure out how some of these factors are pivotal in improving the credibility and stock value of biogas entities.
Technological Innovation
Technological advancements in
biomethane production can significantly enhance operational efficiency and yield. Higher efficiency translates to higher biogas yields and lower production costs, making biogas a more competitive energy source. For example, advancements in anaerobic digestion (AD) and feedstock pretreatment can cumulatively increase biogas yields by up to 30%, which may depend on several factors. Implement-
ing advanced monitoring and control systems can further enhance operational efficiency by significantly reducing lost revenues and operational and maintenance costs due to unplanned plant shutdowns, inefficient operations, and capacity utilization. Companies are investing in research and development to optimize the anaerobic digestion process, and feedstock pre-treatment methods, and developing better microbial strains can reduce production costs and improve profitability.
In addition, upgrading technologies play a crucial role in converting raw biogas into high-quality biomethane. Advanced separation technology, can achieve higher methane purity levels of more than 99% with maximum recovery of methane. Investing in such technologies can command higher market prices. More particularly, in current industry parlance, a purer form of biomethane, when inserted into the gas grid, fetches a higher premium as the realization is based on calorific value.
Another idea that’s gathering traction is integrating biomethane production with other renewable energy systems like solar or windmill set up or a biorefinery can enhance overall energy efficiency. A biorefinery offers a significant cost advantage by efficiently converting biomass into a spectrum of marketable products and energy, akin to how a petroleum refinery processes crude oil. The catch
however is such integrations are more viable when operated at a higher scale or capacity. Nevertheless, such an integrated approach maximizes the overall profitability of the set up, and going forward it might very well be the trend that would attract a multitude of investors.
Ensuring policy certainty in the long run
CBG industry through a slew of initiatives in recent years in the form of Capital subsidy schemes to the tune of INR 4 crores per 4.8 TPD CBG plant for setting up CBG projects, procurement of farming implements, setting pipeline infrastructure. Other market promotion and development scheme includes SATAT which underwent several amendments to finally benchmark CBG prices to CNG, the introduction of CBG-CGD synchronization scheme to streamline the insertion of CBG into the city gas grid, exemption on excise duty in blended CNG to the extent GST is paid on inserted biogas/ CBG, and providing market development assistance for sales of Fermented Organic Manure.
In this context, it must be noted that a majority of these policies underwent several overhauls/ amendments to provide a longterm assurance of continuation of these policies to the project developers. Indeed, clear and consistent government policies, provide the much-needed predictability and longer rope for
investment and growth of the Indian Compressed Biogas (CBG) industry.
In addition, increased awareness about the environmental and economic benefits of CBG among policymakers, industry personnel, and the wider public including the farmers can drive demand and support for biogas projects. As more stakeholders recognize the value and potential of CBG, market acceptance and adoption will grow, attracting further investments. Equally important in this context is to emphasize continuous training and development programs for industry personnel to ensure they are adequately skilled and knowledgeable about the latest operational procedures and safety protocols.
Optimization of Financial Resources
Financial optimization is critical to increasing the value of the Compressed Biogas (CBG) sector by improving profitability, market sentiments, and investment appeal. CBG companies can significantly reduce production costs by carefully managing costs and optimizing operational efficiency. This involves improving feedstock procurement upon organizing and consolidating the current fragmented biomass supply chain, implementing contemporary and rightly mapped technology to increase process efficiency and biogas generation, as well as diversifying revenue streams from sales
of by-products such as biogenic CO2, elemental sulphur, value-added fermented manure, and carbon offsets.
Careful financial planning can help to maximize access to existing government incentives including subsidies, increasing the returns even further. Financial optimization also includes utilizing economies of scale, resulting in a lower per-unit spread of overall fixed expenses leading to larger margins. Improved financial health and demonstrable profitability for a larger but diversified (based on feedstock, technology, business model, etc.) number of successful CBG projects shall make the industry more appealing to a wider pool of investors, resulting in higher valuations and funding prospects.
CBG Companies can reduce production cost
Nurturing Strategic Partnerships
Forming partnerships with important stakeholders such as feedstock suppliers, technology providers, and distribution networks can help to streamline overall operations, lower costs across the value chain, and ensure a consistent supply of need-
ful raw materials. Collaborations with research institutions and technology companies can drive innovation, resulting in more efficient production methods and better biogas outputs. Market expansion, both domestic and international, enables CBG producers to generate additional revenue sources and broaden their customer base. Furthermore, strategic alliances with government entities and participation in public-private partnerships can help unlock the needful resources, and increase profitability and growth potential. We are already seeing an increased trend in PPP through the latest MoU entered by the (Oil and Gas Marketing Companies) OGMCs, like GPS and IOCL, TruAlt Bioenergy and GAIL, Praj Industries and HPCL, Everenviro, and ONGC, to list just a few. Leveraging upon each other strengths through such alliances, CBG companies can achieve economies of scale, improved usage of resources, and increased competitive stance, all of which augurs well for more success stories in the industry thus stirring the vicious cycle of increased investor confidence and improved industry valuation.

Recycling of Organic Waste to Biogas & Organic Fertilizer
Experiences and Challenges in International Projects
Recycling more than bioenergy
The production of biogas from organic waste from municipalities, businesses, or agriculture is an important contribution to global climate protection, which is also supported by India by building numerous bioCNG-production plants. The recycling of organic waste relieves landfills and prevents the emission of methane gas, which is extremely harmful to the climate. Instead, biogas and a high-quality organic fertilizer are produced from the
organic waste using anaerobic digestion technology in indus-trial plants. Biogas is a renewable, storable, and flexible energy source from which biomethane, bioCNG, or bioLNG can be produced through further processing steps (CO2 separation, pressure increase, liquefaction). These biofuels can replace fossil fuels and significantly reduce emissions of climate-damaging CO2. The CO2 separated in high purity during biogas upgrading can be liquefied and then also be recycled and used in food and beverage production. Very sustainable e-fuel can also be produced from the separated CO2 by methanation with green hydrogen. With CO2 liquefaction and CO2 utilization, the biogas plants even achieve negative CO2 emissions.
Strong market growth in India and technology transfer
India has become one of the fastest-growing markets for bioCNG plants. Since 2015, proweps has been supporting local partners in India as an engineering company in the realization of anaerobic digestion and bioCNG plants. The comprehensive sup-port includes technology and know-how transfer, engineering as well as support in the construction and commissioning of the plants. Many years of experience in the implementation of anaerobic digestion and biogas upgrading plants are also the basis for the current projects in India. For the implementation of
the Indian plants, machines from Indian suppliers are used where suitable. Special machines that are not yet available in India are imported from abroad and supplied by proweps. This combina-tion of local value creation with the import of key processing equipment makes it possible to implement competitive technical solutions in India.
Pretreatment of organic waste is essential
The technology for the recycling of organic waste includes an efficient processing technology that efficiently separates the organic part of the waste and the fraction suitable for the production of biogas from the impurities (plastics, glass, metals, textiles, stones, sand). Of great importance in processing is the separation of mineral components such as glass, stones, grit, and sand, which otherwise cause excessive wear in the plant, can be deposited in pipelines and tanks, and leads to longer un-wanted interruptions of operation. During processing, a homogeneous, pump-able waste sludge with a high dry matter (up to 20 % dry matter) and a high fermentable content is produced, from which biogas is then produced in a two-stage anaerobic biological process. Municipal organic waste has a high inert content, depending on its origin. German source-separated biowaste with a high proportion of garden waste contains sand contents of up to 25%. Our ex-
perience with Indian municipal organic waste shows that there is about 3-5% sand in the waste. Therefore, there are significant inert fractions in organic waste, which must be taken into account in the design of the plants to avoid the problems mentioned above.
The following figure shows the separated foreign substances from a fully automated waste treatment plant in plants that were planned by us.
Picture1: Separation of contaminants before anaerobic digestion
With the processing technology, sand is continuously separated in very good quality with little organic loss, even with a small particle size. Recycling the sand, for example in road construction, is conceivable. Plastic is also efficiently separated be-fore fermentation, which is also of great importance given the high quality requirements of organic fertilizers that are produced.
Digester technology - high availability, low electricity consumption
The digesters used for waste fermentation are usually operated at mesophilic temper-ature and are equipped with central, slow-running, energy-efficient, and maintenance-free agitators. The heat supply to the digesters is provided by heat exchangers that are set up outside. Heat exchangers in the large digesters are deliberately avoided, as organic deposits on the pipes can cause problems with heat transfer, and cleaning internal pipelines is not possible without a longer interruption of operation. The digesters used now have volumes of up to 10,000 m3 and interruptions to the operation of such big digesters must be avoided as far as possible. Experience in Europe shows that with the efficient processing of organic waste discussed above, the digesters can be operated for 10-15 years without interruption of operation. High plant availability is an essential prerequisite for the profitability of the plants, especially if the proceeds of the plants are generated only from the sale of energy and without waste treatment tipping fees. At this point, it should also be noted that the quality of the machines used is also of great importance in ensuring high system availability. Therefore, economic trade-offs must be made between higher costs for high-quality but robust machines and the associated significantly increased system
availability.
The biogas from the fermenters is conditioned (coarse and fine desulphurization, drying) and then upgraded to biomethane. There are numerous applications for its use, such as feeding into existing natural gas networks (a common practice in European plants) or high-pressure compression and production of bioCNG with storage in mobile cascade systems, which is usually practiced at Indian plants.
Organic fertilizer – another recycling product.
In addition to energy production, the production of a high-quality organic digestate product that can be used directly without further processing is also of great interest. This is primarily achieved by efficiently separating the foreign substances during processing. The digestate can be used either in solid or liquid form. In European plants, the liquid fermentation product is very often used directly in agriculture as an organic, high-quality biofertilizer. The national quality requirements for the fermentation products
are met safely and permanently with the technology described, in particular, due to the efficient waste treatment technology. Complex solid/liquid separation and wastewater treatment can then be dispensed. The chemical analysis of a high-quality organic fertilizer produced from organic waste in the fermentation plant in Västeras is shown in picture and the following table.
Picture3: Certificate of biofertilizer produced in Västeras anaerobic digestion plant
Picture2: CSTR-digesters Indore, India and Västeras, Sweden
Results of heavy metals and visible contaminants from latest reports compared to legal requirements in Sweden:
In India, there is currently no market for the utilization of liquid digestate. Rather, a solid-liquid separation is carried out and the excess water must be cleaned at great expense before it is discharged into the public sewer system. Unfortunately, valuable nutrients such as nitrogen, phosphate, and potassium are removed from the circulation here. The solid digestate produced during solid/ liquid separation must be composted, mainly to reduce the water content to < 40%. Composting is usually carried out by large, land-consuming windrow composting with aerotillers. In this process, water is evaporated in particular by the residual biological activity and the associated heat generation, as well as by solar, and thermal energy. Against the background of the general drought and water shortage as well as the possible recycling of valuable nutrients, the use of liquid fermentation products could make more sensible use of the water contained in the waste in addition to the nutrients.
References in Europe and India
The technology for the recycling of organic waste for bio-CNG production has also been successfully introduced in India. India's largest bioCNG plant in Indore, which up to 600 tons of municipal organic waste have been used daily for bio-CNG production for many years, was planned by proweps envirotec and built by GPS Renewables as EPC contractor. Meanwhile also waste pre-treatment plants at other locations in India have been installed. In the pretreatment plants, a homogeneous, pumpable, low-impurity waste sludge is generated, which is then used in existing digesters at other locations for biogas production. Treatment plants can also be easily integrated into wastewater treatment plants that treat municipal sewage sludge anaerobically. The existing fermenters of the sewage treatment plants then jointly ferment waste sludge with sewage sludge (co-fermentation).
Co-digestion with waste sludge significantly increases the energy yield of the fermenters as the cultivation conditions improve (nutrients, C/N, etc.).
Using existing infrastructure to treat waste slurry is an interesting cost-efficient organic waste treatment solution.
One of the largest bio-CNG plants in Scandinavia is successfully operating in Västeras, Sweden. The Swedish plant also recycles municipal organic waste, which is used to produce bioCNG and, as already explained, a high-quality organic fertilizer. As a part of comprehensive expansion and modernization of the plant, a new, very efficient sand separation system was installed. Furthermore, a thickening technology for the new digester was integrated to increase the solids retention time and the specific biogas yield. A new pasteurization system for the liquid digestate at a reduced pasteurization temperature was integrated to reduce the plant's process heat requirements.
Technology flexibility
It is evident in all plants that a high degree of flexibility of the technology is very important concerning the very fluctuating waste compositions. For example, the impurity and moisture content of organic waste are subject to strong seasonal and collection area-dependent fluctuations. The process technology for waste treatment must be able to reliably process organic waste and have the necessary flexibility to safely process qualitative fluctuations in waste quality. In particular, the fluctuating water content of the organic waste is of great importance when selecting plant technology. The fermentation technology described above, which has already been implemented in numerous plants with many years of operating experience, can process a wide variety of organic waste, regardless of the water content. The flexibility of the process technology enables the plant operators to process a wide variety of organic waste, e.g. kitchen waste, stored food from supermarkets, and slaughterhouse waste, and thus react flexibly to the respective market situation to ensure the best profitability of the plants. The direct recycling of high-quality digestate products without further treatment steps such as separation of impurities and composting is another important advantage of the process technology described, as the plant operator can also react flexibly and future-oriented to market requirements with different products. The composting of fermentation prod-
Technology flexibility is the key for biogas success
ucts has a high additional land consumption and, in the case of closed, forced-aerated systems, also an additional high electricity consumption. The exhaust air from forced-aerated composting systems requires complex, energy-intensive cleaning to minimise odour emissions in the vicinity of the plants. When selecting technology for waste treatment, many factors, including site-specific ones, must be taken into account to ensure that the most economical, sustainable, and flexible concept is ultimately realised. With the experience gained from many internationally implemented plants with a wide variety of organic wastes and market characteristics, we support our partners with holistic engineering services to achieve these goals. We also provide support in the procurement of critical process components such as pretreatment, pumps, agitators, measuring devices, and others.

The world is going through a period of ‘massive change.’ Nowhere is this happening as fast as it is in India. Although technologies for biogas production are important drivers of such change, technology alone is not enough, other enablers are needed. Especially if change is to happen at the pace and scale needed to protect the people of the world from the effects of catastrophic climate change. Those other enablers are project finance and sustainability reporting.
We need project finance to make sure that those sustainable energy projects actually happen.
But this is not just a local issue. So, we also need sustainability accounting to make sure that those projects satisfy the compliance needs of every actor involved in the trade of goods and services, all the way from producers in places like India to consumers in places like the EU.
Nothing is sustainable until it can be proven to be so. So, finance and sustainability accounting are intimately linked, in particular through international trade.
The goal of this article is to illustrate how the revolution in transition finance and sustainability accounting is playing out in the EU and indicate how this creates an opportunity for India as
it transitions to its new sustainable growth model. The switch from natural gas to biogas has an important role to play in this transition.
Solutions to the Fundamental Problem of Transition Finance
The fundamental problem of transition finance is how to efficiently manage the very large numbers of small projects needed to make that transition happen. These include local refineries, their solarisation, the aggregation, processing, transport and storage of feedstock, and the treatment of by-products and their transformation into bio-commodities such as
animal feed, biochar, bioplastics and green chemicals. All of this is needed to make the system work, but most of these projects are small, technical, and risky, of a kind that traditional lenders struggle to assess.
The energy upgrading of buildings in Europe is an area where progress has been made in solving the problem of transition finance. This is clearly very different from the energy sector in India. However it may help to stimulate new thinking about how to accelerate the growth of sectors such as CBG.
Building upgrades in the EU require insulation, solar panels, heat pumps, and renewable energy systems that feed into local smart grids. Their financing usually relies on energy savings and an increase in the value of the building due to its higher energy performance. These rely on a good choice of technology, stable policies and predictable weather. However banks are generally not equipped to handle such complexity at low cost. They have started to develop new financing models that allow them to process complex loan requests more efficiently. This requires the use of techniques such as project bundling, securitisation, and servicisation. It may require the creation of alternative economic structures such as ESCOs - Energy Service Companies or Energy Communities, a form of social enterprise owned by citizens and local government. New professional as-
sociations have emerged to help accelerate the adoption of these new approaches to small project finance. These include SEFA the Sustainable Energy Finance Association, but there are many more.
Part of a Bigger Trend
These changes are part of a bigger trend which may be described as ‘Impact finance.’ It is happening in Belgium and in Europe more generally. On November 8, 2023, Impact Finance Belgium organized the second Belgian Impact Finance Day. Hans Stegeman, the closing keynote speaker summed it up saying that more than “financing change, we must change finance.” He is the Chief Economist at the Netherlands-based Triodos Bank. He is convinced that our economic system needs to change fundamentally and that the financial sector has a crucial role to play in this. That change is already happening.
Green mortgages are an early example of the innovative financial products that are emerging from this kind of thinking. They provide borrowers with preferential interest rates when their project has a positive impact on the climate and the environment. Transition finance for business is another area where innovation is happening. ASDA, a UK retailer, has partnered with HSBC which offers loans to suppliers at preferential interest rates for their sustainability projects.
We are only at the start of this revolution in transition finance. It is happening faster in some countries than in others. And there is still a long way to go before such tools become mainstream.
A Just Transition
An important policy goal in the EU is to make sure that the energy transition is fair and that all of society can benefit. Many in Europe even struggle to pay rent or the energy they need to heat their homes in winter. When landlords transform the buildings they own, to make them more energy efficient, they often want to increase their rental income. But local governments want to avoid rents being increased to the point where tenants can no longer afford to pay them. This is one reason, among others, why we talk of a ‘just’ transition in the EU. This need has also become a driver of innovation in transition finance. Over the last ten years, innovative models have been successfully piloted, that strike a balance between the needs of all the stakeholders. They seem to work best in the case of social housing projects, where the local government has a significant role in commissioning the work. Ghent in Belgium is generally considered a pioneer in this regard. But it is not the only one.
A Revolution in How Value is Measured
Value in business is no longer
measured exclusively in financial terms. Increasingly businesses have to report on the ‘impact’ their activity has on the climate, the environment and society. Increasingly, the ability of businesses to report on ‘impact’ determines their access to the products of transition finance.
This trend started to emerge in the 1960s with the concept of CSR or Corporate Sustainable Responsibility, based on a voluntary system of ‘triple bottom line’ accounting. In 2017, the EU published the NFRD or Non-Financial Reporting Directive. This required all companies of a certain size to report on the non-financial impact of their activities. In 2021, this was replaced by the CSRD, or Corporate Sustainability Reporting Directive, giving more explicit guidance as to how corporations should report on the impact of their actions. More recently, the CSDDD or Corporate Sustainability Due Diligence Directive requires large companies in the EU to report on the impact of the activities of their suppliers, whatever their location. The CBAM or Carbon Border Adjustment Mechanism, and the GCD or Green Claims Directive have also emerged to create a level playing field for companies that are trying to act more sustainably. The EU Taxonomy is aimed at investors and guides how to tell if an investment really is sustainable.
All of this legislation, intended to encourage businesses to behave sustainably, has created a com-
pliance need which companies can fulfil only with the help of their suppliers, many of which could be in India.
What This Means for Suppliers
On the face of it, such legislation is aimed at the biggest corporations. Nevertheless, the ‘impact’ of those large corporations, for example in terms of their carbon footprint, is largely determined by the carbon footprint of its suppliers. As a rule of thumb, 80% of the carbon footprint of a large company, originates with its supplies. Suppliers that rely on biogas for energy are ‘better’ than those that rely on natural gas because their carbon footprint in lower. In this way, the switch from natural gas to biogas in India makes an important contribution to the sustainability of the companies and countries to which they export. Someday this will have to be measured and accounted for.

The Main Message
Finance and sustainability accounting are intimately
Carbon is not the only indicator that may need to be measured. In future, there may be a need to report on the impact of sup-
This article started by considering the fundamental problem of transition finance, how to finance very large numbers of small, technical, risky projects, that bankers generally struggle to consider. Solutions to these problems have started to emerge in the EU, and elsewhere. Some of these ideas might help to inspire solutions that will help to accelerate the growth of Indian CBG. These ideas are tied up with new thinking about the economy and about how to measure value. This is not something vague and abstract. It is increasingly driven by new legislation. Although this legislation applies primarily to companies in the EU, it has implications even for small businesses in India. Now is a good time to think about what it all means for India, and how best to work with partners abroad to achieve the sustainability goals that we all need so urgently.

Turning Difficult Waste into Opportunity:
Combating Pollution with Innovative Biogas Solutions.
In recent years, the mounting issue of waste management has become a pressing environmental concern. Cities across India are grappling with the increasing piles of municipal solid waste (MSW), while agricultural residues like paddy straw are often burned, releasing harmful pollution into the air. These practices not only contribute to environmental degradation but also significant health risks to the population. The improper disposal of waste leads to the contamination of land and water sources, the emission of green-
house gases, and the deterioration of air quality. As our cities and farmlands struggle under the burden of waste, the need for a suitable solution has never been more urgent.
In the quest for sustainable energy solutions, Arciplug Ltd, a Finnish innovation powerhouse, is setting new benchmarks in biogas production. Their patented proven biogas digester technology, capable of processing a diverse range of challenging waste materials with unprecedented efficiency, is poised to transform the industry.
Transforming Waste Management
The company’s biogas digester stands out for its ability to handle materials traditionally deemed difficult for biogas power generation. From municipal solid waste (MSW) to agricultural residues like straw, this advanced technology processes up to four times more solids than conventional systems without the need for additional water. This not only enhances efficiency but also cuts operational costs, making the technology both economically and environmentally appealing.
Handling Challenging Waste
One of the primary challenges in biogas production is dealing with waste materials that are difficult to break down, such as MSW and agricultural residues. Traditional biogas plants often strug-
gle with these types of waste, requiring significant amounts of fresh water to process them and resulting in lower gas yields. This company’s digester, however, excels in processing these challenging materials, offering a robust solution that doesn't compromise efficiency or gas yield. Municipalities producing enormous quantities of waste face significant challenges in disposal and resource management. Their digester offers an effective solution by converting waste into valuable biogas and organic fertilizers. This not only reduces the burden on landfills but also provides municipalities with a renewable energy source and a revenue stream from fertilizer sales.
Agricultural and food waste represents significant underutilized resources. By processing these materials into biogas, the company’s technology helps farmers and food producers reduce waste, lower their environmental footprint, and generate additional income. The digester’s ability to handle diverse agricultural residues and food waste makes it an attractive option for rural areas and food processing industries.
Energy crops and crop residues like rice and wheat straw are often left unused or burned, contributing to pollution, and wasted resources. Their digester can effectively convert these materials into biogas, providing a clean energy source and reducing greenhouse gas emissions. This
capability opens new opportunities for sustainable agriculture and rural development.
Water Conservation
Making water-free processing technology particularly relevant as water scarcity is a growing concern globally. By eliminating the need for additional water, the digester not only conserves precious water resources but also reduces the operational complexity and costs associated with water management in biogas plants. This innovation is especially beneficial in arid regions or areas facing water shortages, where traditional biogas production methods are not viable.
Superior Efficiency and Cost
Savings by Local Manufacturing
High Organic Loading Rate (OLR)
A plug flow biogas reactor can handle high organic loading rates due to several key design and operational characteristics such as:
• Flow and Retention Time
• High Microbial Activity
• Efficient Mixing and Contact
• Stable Operating Conditions e.g. pH and temperature
• Scalability and Flexibility of the reactor length, volume, and flow rate
The digester’s high OLR due to the above-mentioned considerations in the reactor design,
which is 3-5 times higher than traditional systems, enables it to operate with a smaller footprint while increasing waste turnover and biogas output. This makes it an ideal solution for urban areas where space is at a premium. Higher OLR means more organic material can be processed in a given volume, leading to increased biogas production without the need for larger, more expensive facilities.
Continuous Operation
One of the standout features of the technology is its maintenance-friendly design, which allows for reactor maintenance without halting gas production. This ensures continuous operation, thereby maximizing productivity and profitability. Traditional biogas plants often
require downtime for maintenance, leading to lost production and revenue. This company’s design addresses this issue, offering a significant operational advantage.
Local Manufacturing and Cost Savings
Their commitment to local manufacturing leverages local expertise and production facilities, reducing costs, and fostering sustainability. This approach combines Finnish innovation with local know-how, offering a cost-effective solution from the planning phase through to fullscale operation. By manufacturing locally, the company not only cuts down on transportation and import costs but also supports local economies and promotessustainable development.
Diverse Applications
Company’s biogas digester is versatile enough to handle a wide range of feedstocks (see figure 1), including:
• Municipal solid waste (MSW)
• Agricultural residues, food waste, animal manure, press mud, and energy crops like maize and Napier grass
• Crop plants such as rice and wheat straw
• Same digester can operate with different feedstock.
• Feedstock can be changed in the case that the feedstock market or business model change
Figure 1 Company's some projects with different feedstocks. Note: For Haryana Plant, Biogas volume 16 260 000 Nm3/Y, and Biogas Yield 424 Nm3/T are estimated figures based on our knowledge and available information. Actual data may vary from these projections. Please consider these estimates as indicative, and not as definitive or final figures.
This versatility makes it suitable for various operational scopes, including municipalities managing 50+ tons/day of solid waste, biogas plants seeking advanced technology to boost gas and fer-
tilizer yields, and dry agricultural biomass processing of around 30+ tons/day. Produced biogas can be upgraded and used for various purposes e.g., as vehicle fuel. Because of the meticulous
temperature control within the reactor and proper retention time, all feedstocks are thoroughly digested, leaving no undigested material in the final product. This rigorous process
guarantees that farmers receive a pathogen-free, weed seedfree fertilizer that not only enhances soil health and crop yield but also upholds the highest standards of safety and environmental responsibility.
Finnish Innovation Meets Local Expertise

Optimisation of Stirring Technology
for Higher Biogas Yields and Improved Efficiency of the Biogas Plant
Much is known about the importance of the mixing process for the homogenisation of the substrate and thus for the biogas yield. But does optimal mixing merely have a procedural and technical dimension? Optimising the mixing technology is a means to an end for high biogas yields and thus for the economic efficiency of the biogas plant. However, technical optimisation does not necessarily lead to higher plant profitability. With a view to the economic goal, it is also worth looking at the optimisation of the mixing process from an economic perspective. Agitators are not the most important cost item in the investment budget, so investors taking
their first steps in the biogas industry rarely pay much attention to them. Unfortunately, this view changes quickly during the operation of a biogas plant: problems with the agitator technology, which can be attributed to various causes, increase the importance of the agitators or they become a critical point of the entire plant. Based on this level of knowledge and experience with the mixing system, the search for an identical solution with higher quality usually begins - naturally according to the principles of economic efficiency at a so-called good price. This can sometimes have a satisfactory effect in the case of minor operating problems: For
example, changing the shape, the number of blades, or the material of the propeller can improve the mixing process. Design solutions such as protective clamps or scraper blades can extend the service life of the equipment. Unfortunately, with large discrepancies between the actual process and the installed mixing technology, this is often a misguided measure based on wishful thinking and a somewhat naïve belief in the superior quality of another device as a panacea for all ills. It is worth asking yourself: does it make sense to do the same thing (e.g. replace the product 1:1) and expect a different result?
The search for an optimised solution in the operating phase of a biogas plant is largely limited by the existing technical infrastructure, such as the dimensions of the openings in the tank ceiling, installed masts, inverters, safety equipment, or existing service boxes. Certain decisions are then difficult to reverse for technical and economic reasons alone. Therefore, the best time to analyse and review the technical assumptions made is during the system planning phase.
Which parameters of the mixing system should be taken into account when analysing the overall profitability of the project?
1. The purchasing costs
Theoretically, this is the easiest item to review in the budget for
the total costs associated with the purchase and operation of the mixers. Even at this seemingly simple stage, there may be cost elements that are not included in the bid price, such as an extended warranty that requires the buyer to purchase additional maintenance services from the manufacturer's service department. It is therefore advisable to carefully analyse all tender documents.
2. Operating costs of mixers, especially energy consumption
When analysing the operating costs of mixers, it is necessary to analyse selected technical parameters of the device that have a direct impact on operating costs. These are:
Axial force, also known as thrust
The task of mixers is to set the substrate in motion at the speed required for a proper mixing process; it is therefore crucial to determine what volume flow a particular mixer can generate at the corresponding speed. According to technical calculations, the axial force applied to the agitator corresponds to the axial component of the momentum flow that the agitator transmits to the liquid. This variable is therefore the most important performance parameter. When analysing the technical data of agitators, it is necessary to focus not on the motor power of the device itself, but on the axial force expressed in [kN], which
best illustrates the efficiency of the device in the mixing process. Such analyses may show that devices with a higher motor power have a lower axial force, i.e. a lower mixing efficiency, or vice versa. For price comparisons, it is important to bring the machines down to the same denominator and compare machines with comparable performance regardless of the motor power.
Rotating capacity
Knowing the axial force, the value of the effective volume flow of the liquid at a corresponding speed, i.e. the circulation capacity, can be calculated.
Rated current, i.e. the set operating current of the agitator at the level at which the agitator behaves as intended.
The power factor cos Φ, i.e. the measure of the consumption of electrical energy (active power) by the appliance concerning the energy supplied to it (apparent power). The power factor is used to determine energy efficiencya low value means less efficient utilisation of energy, while a high value means more efficient utilisation.
This data can be used to assess the efficiency of the proposed mixing technology and determine the operating time of the agitators required to move the entire tank volume.
3. Costs of selection and additional services related to
the purchase of devices
Devices are selected based on simplified algorithms of selection programmes or based on the manufacturer's know-how. Both methods are free of charge from the buyer's point of view. The situation is different if the verification of the mixing effect with given substrate parameters, tank data, and the selected mixing technology with specific parameters such as impeller shape or axial force is additionally carried out employing numerical flow simulation, i.e. CFD. This type of service is a form of dedicated analysis of a customised solution and as such requires expensive software and many hours of work by highly qualified engineers. The cost of such services can be obtained from the
manufacturer or estimated by hiring a specialised design office. These costs should be added to the sum of the indirect costs associated with the purchase, as well as the costs of transport, storage, or credit costs.
The above cost catalogue does not exhaust all cost aspects associated with mixers. For the sake of completeness, it is advisable to take a holistic view, including the total cost of ownership (TCO).
4. Service costs
In addition to the costs associated with the purchase, service life, energy consumption, or ancillary services, the costs for service in the broader sense must also be included, i.e. the costs
for the services associated with the entire life cycle of the appliance: Installation and commissioning costs, costs for required maintenance (e.g. oil changes, replacement of high wear parts, etc.) and - if analysed over a longer period - also the costs for inspections, scheduled overhauls, and required spare parts. Some of this data is already available in the planning phase: An estimate of installation costs can be requested from the manufacturer or an authorised service centre. Here, too, it is useful to calculate the operating time to achieve the mixing effect for example, an inspection every 2 years for 0.5h/1h operation and annually for continuous operation. Essential spare parts should be requested from the manufacturer, although the above-mentioned
service life criterion, your own experience with the respective product, or the protective measures used to extend the service life of the mixers (e.g. POM protection clamps) should be taken into account. With increasing operating experience on the construction site, taking into account the special features of the substrate, the process, and the equipment of the respective manufacturer, this information becomes increasingly reliable and calculable.
5.Overheads associated with the lack of availability of mixers
These points are the most difficult to record in the initial phase, but are nevertheless worth mentioning, as this is where the biggest sources of ‘leaks in our biogas ship’ lie. These include the cost of ancillary services associated with the replacement of mixers (e.g. the cost of opening the membrane roof). This also includes the costs for cleaning the tank caused by deposits or the presence of dead zones. Added to this are the costs for unscheduled repairs and overhauls caused, for example, by contamination of the substrate or the operation of the systems in a state of permanent overload. All these costs are usually considerable and, if they are incurred in emergencies, all the more acute (e.g. express production or courier costs). Behind these are even more painful consequences - the cost of downtime and lost production.
It is worth counting the profit from each day of proper operation of the plant and, conversely, how much we could lose from each day of mixer failure. This profit and loss calculation gives us a quantifiable economic picture, and as a result, it may make sense to install an additional agitator as a backup, choose a different agitator design in the digesters (e.g. central or side submersible agitators that can be serviced with little or no gas loss without having to open the roof) or install service boxes for submersible agitators that allow for quick and efficient maintenance of the agitators. Finally, the demobilisation costs should not be omitted from the cost calculation: the cost of disposing of the damaged equipment and the cost of converting the mixing system to a more optimal design if necessary. This is particularly important for those who have resigned themselves to their fate and sometimes replace the agitators twice a year because they think that the agitators are the ‘wearing parts’ of the biogas plant. If this is the case, it may be worth replacing them with more expensive agitators that only work for one year.
As can be seen from the above, when it comes to agitators, it is
worth taking a sheet of paper and a pen in your hand, taking some time, and analysing the possible purchase scenarios and cost aspects for yourself.
It is worth counting the costsbut it is certainly better in theory than in practice.

Successful "Waste To Energy"
Story of Starch Factory in Thailand by Biogas Upgrading to Bio-CNG for Vehicle Filling
We are proud to share a successful ‘Waste to Energy’ project in South East Asia, RE Biofuels Project is Thailand’s first commercial-scale Compressed BioGas (“CBG”) Upgrading and Renewable CNG Filling Station, which started operation in October 2018.
To summarize this iconic project, 24,630 Nm3 of raw biogas per day is obtained by Anaerobic digestion of Starch waste in Korat of Thailand after PSA upgrading to produce 9 tons per day of Renewable BioCNG for NGV. Besides reduction in carbon footprint, the project being installed in the economically weaker section of Thailand helps
Quadrogen Power System (QPS) is a leading Canadian Clean Technology Company that provides innovative and engineered solutions to serve customers in the markets of customized biogas cleanup and upgrading plants, hydrogen purification systems, and carbon capture equipment. In this project, Quadrogen’s PSA system was chosen to purify feed gas to produce high-purity products by effectively removing contaminants such as nitrogen, carbon dioxide, and unwanted hydrocarbons to trace levels.
The unique integrated rotary valve system allows efficient adsorption and separation of contaminant gases without the need for complex controls and numerous switching valves.
This PSA technology can improve overall profitability by reducing costs and providing improved reliability, flexibility, and environmental performance.

cooling water tower, ex-proof water chiller, inlet biogas heat exchanger and gas/water separator as turnkey supply.
Unique integrated rotary valve system allows efficient adsorption
Due to the hot weather in Thailand throughout the year, heat transfer and refrigeration specialists in our technical team, along with our PSA partner, have duly designed separate cooling circuits for this plant. On one side, chilled water supplied by an explosion-proof water chiller was used to cool down the inlet raw biogas temperature, and also compressor discharged biogas temperature. On the other hand, cooling water supplied by a closed circuit cooling water tower was used to cool down the compressor lubricating oil circuit. After numerous calculations and simulations, we managed to achieve the best cooling figures for the system yet maintain the lowest possible power consumption. This in turn brought down the ROI period significantly for the client.
In this project, Adekom Asia, being a biogas compressor manufacturer in collaboration with QPS Canada for the supply of rotary valve PSA upgrading skid, has offered a complete CBG plant solution. This includes a weatherproof containerized VSD water-cooled biogas screw compressor package, closed circuit
In meeting with Client’s expectation on best energy efficiency and reliable performance over years with minimal downtime, one ‘Adekom’ 132kW water-cooled screw compressor package has been supplied for this project. It includes 20 foot containerized design for weatherproof with gas detector, variable speed drive to cater
whatever changes in upstream condition and gas recovery, soft starting for minimizing impact to power supply network. All instrumentation monitoring and control can be achieved locally and remotely via ‘Siemens’ PLC cabinet installed in the safe zone control room. Replacement of oil filters can be conducted without stopping the unit and nitrogen purge line for oil replacement.
Biogas Cooling and Dehydration Solution
Thanks to the extensive application experience and knowhow gained on Biogas projects, we can always choose the best way of biogas cooling and dehydration including the dedicated low-pressure heat exchangers, a comprehensive range of water chillers, and pre-and aftercool-
ers in the process for optimal performance with the lowest power consumption.
Adekom offers fixed and removable tube bundle aftercoolers, energy-saving economizers, and demister separators, all specifically developed for Biogas applications. Applying dedicated design solutions, together with the application of stainless steel grade 316 or 304, ensures excellent low-pressure operation and a high level of protection against potential corrosion from the acidic condensates.
Water chillers and tube-bundle heat exchangers are applied in the water vapour removal phase, with the vapour being condensed by cooling the Biogas down to a temperature of about 20°C like in this project. Once
condensed, the resulting liquid is efficiently separated from the Biogas through demister separators and then remove them by dedicated drains.
The heat exchangers applied in Biogas drying generally utilize water chillers to cool down the process fluid. We offer water chillers designed for heavy-duty operation, assuring excellent operational reliability 24 hours a day and 365 days a year. The vast range of chilling solutions, ensures our chillers offer the perfect solution to every specific installation need.
Special consideration in design has also been put into directing all power supply, cooling water connections, gas inlet/outlet connections and condensate drain lines to one side of the
compressor housing, to facilitate site layout planning and good piping run. All electricals in this project comply with CE/ATEX; while, piping, heat exchangers, and pressure vessels are all in compliance with ASME standards with a U stamp for good management purposes.

For these applications, we provide various non-lubricated compression systems with a
capacity of up to 5,000 Nm3/h in a suction pressure range from 2 to 51 bar abs and a power range from up to 500 kW according to specific customer requirements.
At present, the project plant has been successfully operating for more than 6 years, this not only helps Thailand is stepping ahead on circular economy development with renewable energy from waste to replace fossil fuel energy. But also producing 9-ton bioCNG to fulfill the demand of local transportation. This paves the remarkable way to deliver carbon-neutral energy to any area of the country that is not currently accessible through existing natural gas infrastructure
thus effectively alleviating the problem of local energy shortage and environmental pressure incurred from agricultural waste in rural areas!
To summarize this project, 24,630 Nm3 of raw biogas per day is obtained by Anaerobic digestion of Starch waste after PSA upgrading to produce 9 tons per day of Renewable BioCNG for NGV. Highlights of this project also being installed in the poorest area of Thailand and makes energy more affordable.
