Sustainable revenue generation through biogas to power for dairy industry

Sustainable revenue generation through biogas to power for dairy industry

Energy is the driving force of every living being. As humans, we are completely reliant on the food ,we consume on a daily basis. The dairy industry is a significant supplier of our daily necessities such as packaged milk, cheese, paneer etc, As these products are rich protein source to vegetarian people, there is an increasing demand for quality products. Pune district in Maharashtra state is one of the pioneers in milk production, it is home to some of India’s largest dairy companies, including Bhagyalakshmi dairy, Schreiber Dynamics, and Parag foods, all of which are market leaders in dairy and allied products. Their success also inspires a large number of new entrepreneurs to establish small units in milk and allied products.

Environmental concerns rather than energy recovery is the prime motivator for waste-to-energy facilities, which help in treating and disposing / reusing of wastes. Energy in the form of biogas, heat or eletricity is viewed as an added benefit, enhancing the viability of such projects. In majority of the developed countries, entire waste management system is being managed profitably by private industry or non-government organizations with tipping fee for waste treatment of serving as a major revenue stream.

The primary benefits of adopting technologies for energy recovery from urban wastes are reduction of waste and net reduction of environmental pollution, to the generation of significant amount of energy.

In the current scenario, operating dairy solely for the purpose of selling milk and milking products is not commercially viable; similarly, the costs of fodder, concentrate feed, electricity, and labour are included. To sustain this dairy industry, we must think about generating extra revenue from the waste. As per 2019 Census, India is having 192.49 million cow and 109.85 million buffalo. Due to the low cost of milk and high cost of fodder, animal husbandry has become prohibitively expensive for dairies. Goushala derives all of its revenue from dry cows and this is entirely reliant on do-

nations .We are trying to support them by converting dung into energy and value added fertilizers via waste to wealth projects. This model has been successfully implemented in a number of modern dairy farms and Goushalas.

Agricultural Development Trust, Baramati, Krishi Vigyan Kendra (Farmers Science center), Baramati was established on 1st August 1992 under the affiliation of ICAR. From 1992 to 2008, the operational area of KVK served the entire Pune district; however, with the establishment of a new KVK in district, the operational area has been reduced to the district’s seven tehsils. Krishi Vigyan Kendra, Baramati is model, hi-tech & national award winning KVK of India that has been working for the development of sustainable agriculture for 24 years The aim of Krishi Vigyan Kendra is to shorten the time lag between the technology transfer from research institutions to the farmer’s field in order to sustainably increase agriculture and allied sector productivity and income.

At the Agricultural Development Trust KVK, Baramati, having 500 cattle, we are properly taking care of them. The challenge is to manage a large amount of cattle dung. They were concerned about it in a way that is reliable and does not harm the environment and community. Thus we arrive at the solution of

Biogas Magazine | Edition 19 | 27 biogas that generates revenue and sustainable solution for our problem with minimum capital expenditure. We have contacted Urja Bio System Pvt. Ltd., Pune for the same. After a fruitful discussion, it was agreed to set up biomethanation plant at KVK, baramati, Based on 500 cattle, It was proposed for setting 10 TPD biogas to Power generation project. Keeping future perspective in mind.

The plant is set up for 10 TPD cattle’s dung and is capable to generate @ 400m3 / raw biogas per day. A proper well functional plant is set up at the site. The farm now receives 600 kWH/day electricity (60 kW x 16 hrs per day), significantly reducing major dependency on MSEB (State Electricity Board Power), which previously provided interrupted, power supply leading to usage of diesel gensets. The digested slurry is sent to solid liquid separator, where the solid particles are separated. After micro-organic value addition, we convert it into “PROM (Phosphate Rich Organic Manure)”. Approx 2.5 ton of PROM (Phosphate Rich Organic Manure) is generated at site.

Phosphate Rich Organic Manure (PROM) is a value added organic fertilizer used as an alternative to Di Ammonium Phosphate and single supper phosphate. While all plants require phosphorus, its availability in the soil is limited, posing problems in agriculture. In many areas phosphorous must be added to soil for extensive plant growth that is necessary for crop production. The solubility depends upon pH of the soil, ambient condition and bacteria present in the soil.

Phosphate Rich Organic Manure (PROM) is a value added product produced made by co-compositing high-grade rock phosphate in fine size (say 80% finer than 54 microns) with organic matter collected from various sources such as dung waste, poultry litter etc. To increase the efficiency, Phosphate Solubilizing Bacteria (PSB) and nitrogen fixing bacteria are added. The production of phosphorus rich organic manure (PROM) is standardized to contain 18% P2O5 with 22% moisture is a highly promising, which natural, better and cheaper substitute of di-ammonium phosphate (DAP).

The use of PROM will reduce the cost of fertilization to the farmers, and will also result in the conservation of phosphate mineral, a non-renewable resource due to the high residual effect. The agronomic efficacy of this new P-fertilizer is higher than that of the complex phosphatic fertilizers available in the market today. ‘PROM’ is suitable to Neutral and alkaline soils, which will prove to be a boon to the Indian farmers. In the long run, this product will

succeed as it has significant price advantage compared to the other chemicals. In 2017, was Global Organic Fertilizers market registered volume consumption of nearly 18.23 million tons, amounting to approximately USD 5.87 billion. The global organic fertilizers market is projected to witness healthy growth at a CAGR of 7%, reaching more than USD 8.25 billion through 2023. The changing perception of farmers and end users towards environment friendly farming methods is driving the demand for organic fertilizers worldwide. year

Following are some of the major achievements through this project:

1. Better revenue generation through sale of micro filter digested slurry as organic manure and PROM Generation.

2. Reducing major dependency on State Electricity Board Power(MSEB)

3. Enrichment of soil. 6. Scientific waste managment achieved at source ensuring no land-filling.

7. Reduction in substantial GHG effect.

4. 875 Ton per annum chemical fertilizer replacement. 5. 850 - 900 Ton CO2 footprint reduction.

The separated digested Liquid slurry which is enriched with bio culture upon micro filteration is next step, which is dripable to crops through the tanker, same is available in packaging of 5 liters and 40 liters, in the form Cans, which is being sold to local farmers.

Revenue generation though the project

1. Saving from Power generation: 600 units x Rs. 05/unit x 350 days = 8.75 lakh/year

2. Revenue generation from sale of PROM: 2.5MT/ day x Rs. 6000MT x 350 days=Rs.52,50,000/year

3. Revenue from liquid manure = 15,000 liter x Rs. 0.25 x 200 days = Rs.7,50,000/year

Total revenue generated from this project Rs. 68, 75,000.00/

“ The use of PROM will reduce the cost of fertilization to the farmers.”

Furetank contributes in LBG effort to produce fossil-free shipping

It takes two to Tango! For environmentally conscious Swedish ship operator Furetank, having built methane powered cargo ships is not enough. The key to turning them fossil free is a supply of liquid bio- methane. As a result, ground breaking Furetank shipping has signed a letter of intent with Eskilstuna Biogas, paving the way for the construction of a new biogas facility. The plant is envisaged to be built with the goal of producing 5,000 tonnes of LBG per year. The Swedish Environmental Protection Agency’s subsidy for climate initiatives provides around $15.1 million to the biogas plant project.

“In addition to these grants and public production support for biogas, a long-term agreement with a strong partner is required to make this big investment and achieve the large-scale biogas production that we are planning. It is also very gratifying to find a partner who sees business opportunities in leading the way towards climate neutrality,” – Eskilstuna

Biogas on the partnership with Furetank.

Refuelling of a ship with Liquid Biogas

Furetank became the first shipping company in Sweden and second in the world to bunker LBG in 2018. Now they confirmed to have a clear plan for the transition. There have been a lot of different opinions about shipping, implying as if the shipping industry doesn’t care about the environment. This can pave the way to show to the world that the shipping industry can also go in a fossil-free way. Six hundred (600) cubic meters of liquefied gas can be accommodated in two tanks on the vessel. Fure Vinga, oil/chemical tanker that was built in 2021 and is sailing under the flag of Sweden, was used for refuelling of the ship. Refuelling takes place at minus 162 degrees. The storage takes place at seven-bar pressure and is sufficient for five weeks of operation. Fure Vinga is equipped with so-called dual-fuel engines, which means they can run on both gas and conventional bunker oil.

Good biogas has its price

When compared to running on oil, running on liquefied biogas, both fossil natural gas (LNG) and biogas (LBG), reduces all emissions of sulphur dioxide, nitrogen oxides, and particulates. However, car-

bon dioxide emissions from fossil fuels are lowered as well. In terms of operation, there are no distinctions between natural gas and upgraded biogas. Furetank purchases its gas from Skangas in Lidköping, believing that it is of substantially higher quality than natural gas, with a methane content of 94%.

“For natural gas, methane percent varies between 80% and 92-93%. So, it is good biogas we buy, but the price is another story. The biogas costs twice as much. I wish biogas production soon will be boosted. Our target is clear. We are going for 100% bio.”

Biggest challenge for refuelling gas

Whether it is about LNG or LBG, the challenge is the infrastructure. This is just being built now for LNG, and LNG is fully compatible with LBG.

Furetank LBG stand

Furetank developed a new series of vessels that are on the top of the class according to the IMO’s climate standards for shipping. These vessels operate mainly on LNG, but their ambition is to switch over to LBG. With LBG produced in the right way, they can run the vessels completely without emitting extra CO2 or harmful particles. “Furetank committed to buying at least 75 percent of the produced fuel for ten years. Production is to start in the last quarter of 2023.” - Eskils-

When all shipping companies need to start paying for their CO2 emissions, this will be positioning Furetank one step ahead!
