PREFACE This report proposes a spatial vision with an associated development strategy for the province of South Holland and its vicinity in 2050. The vision was developed during the course AR2U086 R&D Studio: Spatial Strategies for the Global Metropolis in collaboration with the province of South Holland. The studio is a part of the MSc. Urbanism track in architecture and the built environment at the Delft Technical University. The thematic focus of the studio is informed by an ambitious policy agenda that the Province of South Holland has set out: it intends to transition to a 100% circular economy by 2050. In addition to this, a broader context of spatial development trends that shape the region is taken into account. The design proposal is formulated by a team of five students coming from various backgrounds and interests, all master students of the Urbanism track at the TU Delft. Due to their wide range of experiences, interests and cultural backgrounds, interesting discussions arose. We would like to sincerely thank our studio mentors Alexander Wandl, Diego Sepulveda Carmona and Luisa Calabrese for their guidance, useful feedback and insights about circularity and spatial planning. We would also like to thank Marcin Dabrowski and Roberto Rocco for the enlightening lectures during the course AR2U088, R&D Methodology for Urbanism. Hereby we would like to extend sincere gratitude to the province of South Holland and the guest lecturers of the Capita Selecta Spatial and Development Strategies (SDS) for their time and providing us with valuable information.

ABSTRACT The Province of South Holland is an important economic player both nationally and globally with several green ports, knowledge centres and the port of Rotterdam. It is the innovation capital of the Netherlands, leading the circularity vision with multiple stakeholders working together. Due to its strategic position, the province has provided high standards for the quality of life. However, the negative side of this development is the demand on the urban areas to support steady growth and tackle pressures of migration or influx of people. These pressures are leaving the urban fabric unevenly developed. The resulting urban sprawl and crammed centres are creating unequal and unjust living conditions. The conventional household structures have been shifting due to evolving lifestyles and economic opportunities. However, the housing market supply is still aiming towards the higher economic sections of people and is not reflective or accommodative of changing households. In addition, the current practices in the construction and demolition sector make it the largest contributor to greenhouse emissions, and consumer of resources. The province has formulated a vision of at least 50% reduction in the use of primary raw materials by 2030 and completely transforming into a circular economy by 2050. This drive towards the circular economy is dependent on a great deal of knowledge, which is mostly controlled by just a few actors. Spatially, this shift is threatening to leave behind yet another layer of brownfields. Hence, it becomes imperative to promote just spatial conditions and fair sharing of knowledge by utilising these transitioning landscapes in a circular development. These interventions are realised by introducing the Circu-labs and formulating goals under the categories of people, land, material and knowledge. These coinciding ideologies will be accommodated in the ‘circulabs’ which are then implemented in strategic areas that are the transitional landscapes within the South Holland region. The region would have a synergetic urban network where circulabs provide knowledge and support the transition towards a circular construction and demolition cycle with well-balanced and inclusive living environments. The circulabs will act as catalysts to boost the circular economy in construction and also transform South Holland into a lab itself which would be optimised and most sustainable towards the future needs. Keywords - Circularity, Inclusive living environments, Transitional landscapes, Social justice, Fair sharing of Knowledge, Construction and Demolition sector.

INTRODUCTION

South Holland is a province on the west coast of the Netherlands. With the political capital The Hague, the growing creative Rotterdam and 50 other municipalities is South Holland most populous and most dense province in the Netherlands (Centraal Bureau voor de Statistiek, 2019). The opportunities offered by the big cities are constantly attracting people into two urban cores: The Hague and Rotterdam. Due to this strong urbanization, the international port and it’s world-famous greenhouse horticulture sector, is South Holland probably one of the most material-intensive provinces in the Netherlands (Drift and Metabolic, 2018). The Province of South Holland therefore has great ambitions to accelerate the transition to a circular economy in South Holland. The province focuses on three selected value chains in the transition to a circular economy. The construction, agrifood and plastics sector is looking for environmentally and economically sustainable ways of using natural capital and resources.Because there are so many aspects of circular economy that can be faced, we decided to focus on the construction and demolition waste cycle in our project. In the province of South Holland, 5.6 Mton of building materials are used, making it by far the largest material flow within the region (Drift and Metabolic, 2018). In addition to the thematic focus of circularity a broader context of spatial development trends that shape the region are taken into account. By analysing the development trends that shape the region and the construction and demolition waste cycle the research question that emerges is ‘How to utilise the transforming landscapes of the South Holland Province to drive circularity in the construction and demolition sector and relieve the pressure of the housing demand on the urban cores?’ To answer the research questions and its

subquestions, this report will introduce a network of regional living labs. Plugin developments to the existing urban structures. We call them CircuLabs and they exist on the threshold of 3 important sectors.The strong knowledge economy of the region, the large and transitioning construction industry and the agricultural landscapes of South Holland. With our design we are aiming for a region that consists of a synergetic urban network, where knowledge is fairly distributed and supports the transition towards a circular construction and demolition cycle, providing balanced and inclusive urban environments.

CONCEPTUAL FRAMEWORK

TRANSITIONAL LANDSCAPES In the course of our research, we found that studies have shown high and diverse demands on land in South Holland. The agricultural sector still remains the main land user in South Holland, occupying over half of the province’s surface area as of 2015 (Clo.nl,2012). Built-up areas along with housing infrastructure take up only about 20 percent of the overall land. These urban areas, especially in Randstad, are very dense due to the prevailing spatial planning policies of the Netherlands (Ministry of Housing and Physical Planning 1966) which we will depict in detail in the next section. “Land is considered a finite source” which can’t be extended beyond a limit (Amenta & van Timmeren, 2018; European Commission, 2020). The criticality of land depends on the limit to which it can be exploited before it stops acting as an important resource (Kasperson et al., 1995: 25). To use the land to its full potential and bring it under the umbrella of circularity, it needs to be treated as a renewable resource (Marin, 2018).

As discussed in the previous chapters, the project’s goal is to shape the transition from a linear to circular economy in the construction and demolition sector. It also addresses the demands on urban cores and the plethora of landscapes that need to be regenerated. In this chapter the conceptual foundation of this transition is explained. The foundation is mainly based on the following theories. Transitional landscapes, New developmental models, Knowledge distribution, Re-envisioning construction practices. 10

The landscapes of South Holland share an inherent relationship with human activities (Pols et al., 2005). The dutch landscapes are treated as cultural landscapes and the land is given the utmost importance historically in dutch context (PBL, 2019). Land reclamation, urbanisation and industrialisation have been major contributors to the identity of the South Holland landscapes today. These landscapes have in turn influenced the resilience of the social groups and communities dependent on them (W.Adger, 2000). Today’s linear economy witnesses major transitions of land from extraction, reclamation, conversion, development, contamination (especially in the case of industrial activity), usage and finally abandonment. The resultant landscapes

take the longest to heal after undergoing these developments. Ergo, these wastescapes left behind by diverse human interventions are unusable and need to be regulated for efficient revival and reuse. Wastescapes are wasted landscapes or unused land parcels which are usually a result of human activity, industrial activity or spatial development strategies. The industrialisation of older city areas and the rapid urbanisation of newer city areas could be identified as two primary processes for the formation of dross scapes ( Berger, 2006). Brownfields are the results of the process of industrial change, especially in Urban areas (Grimski, & Ferber, 2001). Research suggests that there are over 93800 hectares of industrial lands and Brownfields across the Netherlands. In this new transitioning economy that iaccounts for 30% of areas that are obsolete and eligible for redevelopment. This is more than 30,000 ha of industrial land alone which is wasted as of now (PBL, 2019). These industrial areas are well-connected and in the vicinity of city centres because logistics and accessibility were the main focuses for their initial establishment. These factors give them a competitive edge over greenfield development. Waste scapes provide opportunities for sustainable urban and territorial regeneration. It includes a regenerative system which provides continuous replacement through its functional processes of energy and materials used in its operations (Van Timmeren, 2006). Revitalising wastescapes is a complex discipline and it requires diverse fields of focus making it multidisciplinary. It brings together different concepts related to economy, quality of life, health, accessibility, resources, landscape, environment and infrastructure (Van Timmeren, 2019). Since this is inherently a complex process, it is not just achieved by a single party but requires a collaborative

effort of multiple processes, flows and actors. It requires a systems thinking which allows one to utilise a holistic and transdisciplinary approach across multiple scales and sectors (Cloy, 2019). In our proposal, the plugins will not consume unused pristine lands or green fields. This will prove inefficient and result in more depletion of natural resources. Hence, we will examine the potentials of different types of abandoned landscapes that are left behind due to planning initiatives, transformation stages or industrial activities. The development of these wastescapes, instead of new agricultural fields, has multiple economic, ecological and logistical advantages. Circular management of land aims to reduce the land resource required for new building constructions, transportation facilities, working and residential areas. It proposes densification through remediating abandoned landscapes, recycling and introducing mixed typology buildings for efficiency, economic productivity and flexibility of built land (Preuß & Verbücheln, 2013). Land can be considered a ‘common good’. Common goods are defined as goods that are rivalrous and non-excludable (Lefebvre et al., 2015). Commons are those resources that are held in common (Rocco, 2020). These include resources held by few communities, like agricultural land owned by farmers and industrial land by shipping industries and other actors as such ( Zuid-Holland Circular). In recent developments, the land has been privatised and is controlled by only a few actors owing to the global economy and market (PBL, 2017).

action. (Hardin, 1968). We also had to differentiate between the common goods from the common pool resources. Unlike the common pool resources (CPRs), which work like an open-access regime with no particular resource management system, Commons are guided and negotiated by the people. We are proposing a more informal structure to manage these shared resources. The usage of land by an individual actor under the policies of the province essentially means that it is rivalrous and not accessible to others during the time of use. Hence, the transitional periods of these landscapes become very crucial for our proposal. Our vision strongly emphasises that landscapes which are under transition would be given back to a shared-resource system where after debate and collaboration, all stakeholders of the community can decide how the land can be used to create equal opportunities of knowledge sharing and just living conditions. The Dutch landscapes are of important public interest and belong to everyone (PBL, 2019). The viability of these landscapes during the course of remediation and revitalisation are very important for the whole society (Baldock, Hart and Scheele, 2011). These transitional landscapes are full of potential to address key values of the society, and the problems we face today like climate change, social vulnerability etc. It is very important to make them accessible for diverse uses and to distribute the gains of those uses fairly. This would increase the efficiency of land usage and collective action that would result in the common good.

The tragedy of the commons is a situation in a shared-resource system where individual users, acting independently according to their self-interest, behave contrary to the common good of all users by depleting or spoiling the shared resource through their collective 11

NEW DEVELOPMENTAL MODEL The Post-Industrial city, developed in Europe in the latter half of the 20th century, caused major social, economic and ecological changes. Cities became the main attractors for livelihoods in the process. The rapid and large scale urbanisation has taken its toll on the movement patterns, environment and social behaviour (Banister,1997; Williams et al., 2000; Marshall, 2001). South Holland is a highly urbanised Province (PBL, 2017). Most of the jobs are found in the cities and they have the highest share of knowledge workers and also attract the most foreign immigrants. The main pull factors are the proximity of amenities, job opportunities and the proximity of educational centres (Vissers, 2019). The high population density and concentration of human activity in cities are causing climate change, increasing urban heat island effect, air pollution and waste (PBL, 2017). The everexpanding urban boundaries have become highly dependent on their city centres for functioning. On a city scale, these over-dependencies have led to weaker sections being pushed away from the urban centre and from the advantages and opportunities it holds. In South Holland, Hague and Rotterdam act as the two main economic pillars (OECD, 2007). The Metropolitan region of Rotterdam-The Hague acts as a monocentric system of the whole province which contains multiple satellite towns and suburbs that are over-dependent on them. On a regional scale, a great majority of the economic activity is dependent on this area, which leaves the whole region vulnerable to potential risks. The current growth of South Holland is greater than in the past. Research shows that there will be a need for 12

an additional 250,000 houses in the province south Island by the year 2050 (Zuid-Holland Circular, 2019). The municipality vision proposes that 83% of these houses be built within the urban borders adding additional pressure to the already strained cities (Clo.nl, 2017). This methodology is based on the compact organisation policies in the Netherlands (Geurs,K; Wee,B., 2006). To protect the natural ecological systems, curb suburban sprawl and protect the fragility of the peri urban areas, national spatial planning policies were aimed towards implementing compact urbanisation in various forms. One of the approaches adopted for channelling suburbanisation is to implement "concentrated deconcentration" which aims to accommodate new urban growth outside of existing urban areas in several designated spillover centres (Ministry of Housing, Physical Planning and the Environment, 1977). This policy was embraced as a feasible compromise between concentration and low-density dispersal of urban activities. However, due to the decline of the inner cities, this was further replaced by the ‘compact city’ model. From the late 1990’s, there is a call to relax strong emphasis on compact urban form after the housing stock and the number of inhabitants in the large cities started to grow again after a decade of serious decline (Ministry of Economic Affairs, 1999). These discussions gave way to the replacement of the compact urban development by a ‘Network city’. Network city is a planning concept that would lead to decentralisation and reduced local governance. We have proposed a similar model for our densification strategies. A synergetic regional development model aims at reducing the over-reliance on a single metropolitan area and strengthens the region as a whole. In this new

configuration, all the cities and smaller towns would merge in terms of disciplines and act as a single coherent robust region (Meijers and Romein, 2003). This synergetic, polycentric model strengthens the relationships and the connections between the region’s different cities. It creates specialised and complementary urban centres that vary in size, function and identity but work as one system, avoiding a destructive large scale urban sprawl (Beily and Turok, 2001). A polycentric system that functions with diverse and complementary urban areas can achieve a steadier pattern of development and greater spatial justice (European Commission, 1999). These new development areas are proposed at the peripheries of the existing urban cores at the threshold of the urban fabric and open landscape. These maintain the fragility and the cultural significance of the peri urban areas which are considered the main bridges of the divided worlds of rural and urban (Wandl, et al.2014). In our proposal, the plugins that are created near these multiscalar regions would use the local potentials and promote more local economies that would then be interlinked with a robust infrastructural system that is already in place. This reduces the pressure on the major urban centres to support the transition towards a just and circular development. The economy is diversified and each area supports the other under the systems theory and creates better conditions to address the fundamental uncertainties of this shift.

KNOWLEDGE DISTRIBUTION To put circular economy concepts into practice, citizens, their awareness, mindsets and behaviors play an essential role (Veleva, Bodkin, & Todorova, 2017). This awareness will be brought in only by equal cognition. Central to our vision for South Holland is the assimilation and dispersion of knowledge. There was a keen interest to understand whether knowledge can be perceived as a public good. The technical definition that was pinned down by Elinor Ostrom in her book, Governing the Commons, divides economic goods and units of exchange, on two axes. Public goods are non-rivalrous and non-excludable (Rocco,2020). Knowledge is infinite and doesn’t reduce when someone consumes it and once given can’t be taken away. However, the main issue with characterising knowledge as a public good was that it is not free at the point of delivery. It is an excludable entity. Knowledge is highly privatised in the capitalist economy (Hirschman, 1977). Natural incentives exist to create private goods as accumulation seems to be the natural aspect of human character (Hirschman, 1977). 'Knowledge Commons', a concept which is half socialist utopian and half neoliberal is a belief that technology can enable the effective sharing of knowledge as a resource. The resources that can be shared and explored by all would then act as effective foundations for value creation (Hess & Ostrom, 2006). So to determine and drive knowledge as a public good, we needed to ascertain different forms of provision. Dispersion of knowledge and its just sharing requires the same tools that would support the creation of public goods. Especially, for an entire

paradigm shift, these mandates and legislatures are of utmost importance. The current model of knowledge concentration needs to be diminished because it results in the accumulation of this resource in the hands of a few actors who would, in turn, control the extent of its impact. Distribution of knowledge creates greater benefits and enables the creation of even great value. Since the province's future vision looks at a drastic shift that needs knowledge build-up and innovations, there is a need to establish new networks of knowledge dispersions. These public goods need to be resourced at a global level and mandated through legislation. A shift in the economy and ensuring that this shift would be sustainable, a transition in perspectives is needed (Hobson & Lynch, 2016). Changing the mindset and driving the knowledge about circularity is a multi-scalar and multi-systems approach. Hence, at a policy level, we propose a collaboration between the top-down and bottom-up disciplines so there is a shift in the economy in every household from being passive consumers to more proactive prosumers. The greatest hindrance to achieving this is the lack of knowledge and its distribution (North & Nurse, 2014). It is inaccessible to a whole section of the population to realise this. Our proposal forms an initial seed for an integrated systems approach that connects flows of biocentric and service/ knowledge-centric industries.

community based institutions would have to be supported both informally and also on an administrative level (North & Nurse, 2014). Local economies and new community-based business models would inspire confidence of the citizens more easily and guide them to take an active part in creating the circle (Hobson & Lynch, 2016). Localising the logistics and supply chains would also transform the transportation means and as a result, emissions can be reduced. Localised economies do not mean independent actors, they still rely on each other and the overall region to develop synergies. They bring forward strong and integrated regions that complement each other in terms of functionality and identity and the local economies engage citizens to participate (North & Nurse, 2014).

To engage all the citizens in this circular economy, the new developments should be organized in a way where opportunities for participation and engagement are maximised and a sustainable lifestyle becomes more obvious and easier to achieve (North & Nurse, 2014). For this, self builders need to be encouraged, localised business, social enterprises, small entrepreneurs and local material production and distribution services and 13

material (Veleva, Bodkin, & Todorova, 2017). However, it now becomes very important to understand the shortcomings of a circular economy before transitioning into it fully. In a growth-based economy like south holland, this model doesn't respond to the fundamental problem of overconsumption (Hobson & Lynch, 2016). The only way this can be addressed is if the objectives include zero waste as well as making a robust reusable material bank to establish a zero consumption of new resources.

Figure 2.2| Multifacated nature of Circulabs; Illustrated by authors

RE-ENVISIONING CONSTRUCTION PRACTICES. The construction industry in the province of South Holland uses up to 5.6 Mton of building materials (Zuid Holland Circular, 2017). It contributes to the largest flow of materials within the region. Even though it boasts of recycling 85% of the building materials after demolition, the vast majority are not reused or used only for their second-grade value (Metabolic, 2019). The province has ambitions to transform the region into a circular economy by 2050. Policies in the region already recognise that the construction sector needs immediate mitigation efforts that aim to tackle greenhouse gas emissions, climate change, protect natural and renewable resources and transform into a circular economy (Hodge et al., 2010; Sieffert et al., 2014). A circular 14

economy can be described as a model of development where the end-of-life waste concept is replaced by generating alternate uses for recovering materials, by recycling, revitalising and reusing them. These materials undergo various transformations due to production, utilisation, distribution and consumption processes (Kirchherr et al., 2017). The new model emphasises the necessity of maintaining the products and materials in the flow so that the dependence of new and virgin resources can be diminished which are usually accompanied by negative environmental impact (Mirata, 2004). The concept of circularity has recently garnered attention as a means for policymakers to respond to sustainability issues (Veleva, Bodkin, & Todorova, 2017) (North & Nurse, 2014) (Hobson & Lynch, 2016). However, in many critical conclusions, this refers to a zero-waste model, in which as much waste as possible would be turned into a reusable resource

Effective and comprehensive collaborations between scientists, policymakers, government ministers and companies must be established. The focus should be on expanding the scale and the quality of construction and demolition recycling and its potential to also be reused to construct new buildings which are energy efficient. Although, circular construction is not only about resource recovery, re-use and recycling, is a much broader concept (Ghaffar, Burman & Braimah, 2019). The stakeholders in the construction sector lack proper incentives to innovate in terms of dismantling strategies and material recovery, since the market hasn't incentivised them yet. The onus then falls on the government to issue mandates to meet the recycling targets and provide reasons for them to invest (Ghaffar, Burman & Braimah, 2019). It becomes quite complex since new legislations are required and not the general appreciation for global challenges and environmental concerns (Dahlbo et al., 2015; Kurdve et al., 2015).

COLLECTIVE SYNERGIES

CONCLUSIONS The conceptual framework has been guided by the different theories which were discussed in the earlier sections. The fair sharing of knowledge ideology has put the focus on the notion of whether knowledge can be considered a public good. This is especially important for the transition of the current linear economy into a circular economy. It also addresses the inherent relation between knowledge and development of the current socialtechnical systems of construction practices. Also, the notion that land is considered a common good is strongly intertwined with socio-spatial justice for large segments of weaker and marginalised parts of the society. Since the land is a finite source, it is important to aspire for its fair distribution and access. The transitional landscapes of South Holland should be taken into consideration for their regeneration and reuse. Then the expectations of these landscapes along with the other

abandoned landscapes and waste scapes should be equally distributed. Along with the prosperity of developers and construction industries, the well-being of the citizens needs to be considered. Even though the land itself is owned by a few, it would still cater to people, planet and prosperity. The role of the strategy is to guide, stimulate and educate so that the transition from a linear to a circular economy can happen with a fair distribution of resources and knowledge. The inherent relation between the development of a society and their dependence on landscapes are also reflected in our proposal. The transformative landscapes can revitalise their support systems and also be extremely valuable to the societies that are dependent on them. The transition of these landscapes will happen simultaneously with the fair dissemination of knowledge regarding the new methods of achieving circularity in the construction and demolition sector particularly. 15

South Holland plays a very important role at a global scale due to its multiple connections; both through land and sea. The Port of Rotterdam is one of the most important connections of the country and Europe receiving up to 29,400 sea vessels a year and providing a logistics platform to import and export around 470 million tons of commodities. In land, South Holland counts with the immediate connection with Belgium with a shared border and

it is connected through a combination of highways and railways to Germany, Swit- zerland and France to name a few. South Holland currently has a population of 3.7 million people. The province comprises 52 municipalities. A few of the most relevant cities are The Hague being the diplomatic center of the Netherlands, Rotterdam being a key port of Europe along with its rich industrial sector, Leiden and Delft housing world class universities. 19

The regions economic development is based on the advanced industrial sector, leading knowledge institutions and the agricultural sector. The industrial sector focuses mainly along the port of rotterdam and spreads with less intensity through the region mainly on the periphery of large cities. The knowledge sector is more compact and it is located in the larger cities of the region, the most important institutions are located in Leiden, The Hague, Delft and Rotterdam.

Types of Rental Property

South Holland’s Population is quite diverse. The region is heterogenous in nature owing to the migration patterns over the past few decades.

Regular Housing

Household structures

The traditional family structure is also evolving due to the change in current economic and educational trends. Due to this change in the conventional demographic structures, multiple housing typologies have resulted.

Traditional Family

There are more students that live by themselves in the places of education and South holland also has aging population.

New Structure

Housing for Family

Due to the high employment oppurtunities that the area offers, there are a lot of immigrants that are willing to settle down. These demographics usually make up the minority and the current housing system doesn’t work for them efficiently.

Row Houses

Single Family Units

Multi Family Units

Demographic trends

These diversities have resulted in multiple housing typologies like the traditional row houses, independent apartments and multi family units. When it comes to ownership, till 1985, there has been a clear majority of rental properties but starting from 1985 there has been a major shift in the attitudes and housing demands.

Figure 2.23| Material flows in the construction and demolition cycles; Illustrated by authors, based on Metabolics (2019)

Within the construction industry in SouthHolland a total of 5.6 megatons of construction material is used in 2016. That makes the construction industry the third sector concerning material flows (Metabolic, 2019). On the diagram on the previous page, it is clear that the material flows on the left side are much more intensive than the material flows on the right side. In this current situation, the construction industy wouldn’t be able to meet its own needs. In the construction sector, concrete is the material with the highest influx. The total 28

influx in a year is 2.1 megatons (Metabolic, 2019). By far, the inflowing concrete is mostly used for new construction and barely for the maintenance of buildings. Due to the lack of quality and quantity in the outgoing materialflows, a constant influx of new construction materials is needed to provide for new construction projects. Within the province of South-Holland the outflow of construction materials amounts 3.9 megatons. 50 percent of this material outflow consists of stony rubble. Mostly

this stony rubble is used in a low-value way. 95 percent of the stony rubble is used as an underlayer for new roads. In total 1.06 megatons is downcycled. Important to notice is that a significant part of the asphalt outflow is recycled. 0.78 megatons asphalt a year is reused for the realization of new roads in SouthHolland. At last, this described process of material flows ensures that there is a CO2 emission 0.28 megatons a year. This emission of CO2 is mostly from the construction of roads.

The flows illustrated on this map concern the flows of demolition waste (concrete) within the region. The blue areas are the demolition sites from where material waste is transported to several landfills. A small part of the demolition waste is transported to recycling facilities, where concrete will be downcycled. These maps shows on a spatial way the linearity of the current system. 31

POTENTIAL LANDSCAPES Urban Areas under Transition Industries are constantly under transition. These leave behind large footprints of buildings and supporting infrastructure which can be brought into the new models of development. Large buildings are also abondoned and they need to be assigned new functions by either recycling or refurbishment.

Drossscapes These are the areas left behind during the design stages on infrastructure development and planning. These abondaned landscapes have high potentials due to their strategic positions.

Agricultural Lands South Holland has large hectares of land for farming, livestock grazing. These are the potential lands for future developments, developing new materials for building construction and establishing biobased plants.

Green Houses The green houses are located mainly in Westland which has three of the six green ports in the Netherlands and it spreads to the west to Pijnacker and Zoetermeer. It is the main source of economy in south Holland and has the potential to supply organic residual streams into the construction sector.

Brown Fields

Figure 2.32| Map showing the connections between the existing diverse potential landscapes. Illustrated by authors

The fossil fuel based Industry and the port of rotterdam are in transition due to the drive towards circularity. The land these industries leave behind is contaminated for immediate use so they need to be transitioned in multiple phases.

Figure 2.33| Potential landscapes: Urban, Drosscapes, Agricultural, Greenhouses and Brownfields; source:Google Earth

CONSTRUCTION LANDSCAPES Concrete Plants The concrete plants are located close to the urban centres. The concrete plants are usually very well connected to waterways and railways for transfer of raw materials. In case of wet concrete plants, it is ideal that they are located within 20km of construction sites for efficient transfer and to maintain the quality of the material. The dry precast concrete plants can have a radius of 90km.

Logistics Hub These are the main connection points between the developer companies, material banks and the construction sites. These are usually located in transitional industrial landscapes for efficient reuse of the land and the infrastructure. These can have storage units plugged in.

Demolition Sectors On the demolition sites, materials are broken down and segregated. The concrete is separated and sent to recycling areas where it is treated. The material is then transported to be used for its secondary value to lay down foundations for roads and buildings. The light weight construction materials are sent to material banks for reuse.

Recycling Centre The building materials that can’t be directly used and are in debris form are brought to the recycling centres. The materials are then either sent to material banks for reuse or to the new construction sites for roads and foundations. (Ministerie van Infrastructuur en Waterstaat, 2016) 36

CIRCULAR CIRCULAR DEVELOPMENT DEVELOPMENT PRACTICE PRACTICE In the region of Zuid Holland, there are already multiple ongoing experimental developments showing the aproaches to tackling the problem of circular construction and demoliton cycles. We identified two dominating aproaches, which we we illustrate with examples of Green Village laboratory in TU Delft and Hof van Cartesius community village in Utrecht.

There is a fundamental gap between these developments. On one side a project, where a private market actor funded by large capital builds a research project on its own private land. The project cannot actually bring any benefit to its users, since it serves no inhabitants, and it only serves to further accumulate knowledge on the campus.

On the other hand, there is a grassroot community project inc ooperation with municipality, that manages to actualy development bringing value to its surrounding, despite the lack of knowledge and resources. Bridging this gap between the private and public sector as well as knowledge and users is essential to bringing systematic transition towards a circularity that is accessible to everyone.

SOUTH HOLLAND IN 2050 39

GOALS AND AMBITIONS To tackle the problems we found in the analysis, we created a vision for the region of South Holland. In 2050 we foresee South Holland as a region that consists of a synergetic urban network, where knowledge is fairly distributed and supports the transition towards a circular construction and demolition cycle, providing balanced and inclusive urban environments.

To achieve this vision, we formulated ambitions under four categories. All categories are interdependent on each other and works synergeticallly. These goals can be evaluated after the proposed interventions to find out if the project was successful. Our strategy is to achieve this by introducing a network of regional living labs, circulabs. Circulabs are plug-in developments to the existing urban structures. They exist by connecting 4 important sectors of circularity.

- KNOWLEDGE ECONOMY - CONSTRUCTION LANDSCAPES - AGRICULTURAL POTENTIALS - NEW URBANISATION MODELS The strong knowledge economy of the region, he large and transitioning construction industry and the agricultural landscapes of South Holland. They are a place for experimentation and reinvention across all four sectors, making them the hubs of new socio-economic organisation.

In 2050, the region of South Holland consists of a synergetic urban network where In 2050, the region of South consists a synergetic urban network circu-construction circulabs provide knowledge andHolland support theoftransition towards a where circular labs providecycle knowledge andwell-balanced support the transitionand towards a circular construction and deand demolition with inclusive living environments. molition cycle with well-balanced and inclusive living environments.

The current construction and demolition system is highly energy intensive. Every stage emits CO2 into the environment and requires electricity, fuel, water and infrastructure. With our strategies we try to create new and improved cycles for localized developments, with different actors contributing and learning from the process. It includes developing new bio based materials that can potentially 56

change the face of construction while optimizing the recycling process. Bio based materials with high CO2 capturing and recyclability potential are grown in circulabs near the agricultural sector. Localised manufacturing Units would make the system more efficient. The residual organic wastes from the green ports will also be added to the construction stream for creating bio-composites.

Figure 4.2| Intervention strategy 2; Illustrated by authors

Creating material banks and maintaining a database of all the construction materials in circulation, would help localizing distribution and making storage more efficient. These database would not just help the developers but also local citizens to build their homes with reusable materials. The strategies also include developing new ways of designing buildings that are better equipped to be

adaptable and flexible ensuring longer life spans. With help of the knowledge and research centres, innovating strategies should be developed for dismantling a building rather than demolishing it. These elements could be stored in the material banks for future distribution, high value recycling and reuse reducing the pollution cause due to demolition and recycling. 57

SPATIAL STRATEGY To identify the potential areas for the circulabs we set up a strategy to assess them based on a wide range of criteria.

Firstly, an important criteria is the presence of infrastructure in the area. South Holland boasts of rich infrastructure networks. The Circulabs are located at nodes were waterways, railway and highways intersect to benefit from the agglomeration power generated by them. Intermodal infrastructure nodes allow hubs to easily achieve region wide coverage and create a synergy between the hubs. The investment costs in the hubs will therefore be lower, so that they can be invested in sustainability and circularity.

in the proposed transitions, otherwise, by leaving them behind, we risk creating yet another layer of brownfields in the landscape. We also looked at the existing construction landscapes that couod be upscaled and the existing infrastrcutue could become more robust.

Secondly, we looked into the existing industries in the region. The existing industries are potential links to a more circular construction cycle. Construction ‘waste’ from several demolition sites can be processed and reused to foresee future projects. The industries need to be transformed in this journey towards circularity. Hence, it becomes necessary for these existing industries to be integrated

We also looked into the potentials of biomass.Organic (waste) material can be used as a building material whereby it can potentially change the face of construction while optimizing the recycling process. Hemp, mycelium and duckweed are materials with great potential that could benefit from the strictly controlled and highly technical agricultural practice in the region.

The circulabs will open the possibility for a regional network of materials. Every circulab with it’s own focus will supply the region as well as receives materials from the other hubs.

Current situation

Interventions

Final situation

With the urban area of Leiden-The Hague-Rotterdam-Dordrecht, South Holland is part of the Randstad. The Randstad is a multinucleated urban concentration in the west of the Netherlands, a metropolitan area where various agglomerations with their own city centers have grown or grow together. Major expansions have taken place around the major cities of the Netherlands and also in South Holland. Residential areas and industrial areas have gradually grown around the cities. In recent years, more and more people want to live in the city because of the opportunities that are offered there. However the increasing pressure on the cities ensures that living in the cities is not affordable for everyone.

With the high demand for housing and the inevitable transition to a circular economy, we see an opportunity to change the current situation. With implementing the circulabs in existing transforming landscapes we try to balance the migration flow within the region of South-Holland. Circulabs are plug-in developments to the existing urban structure. By using and redeveloping transitional landscapes, the circulabs relieve the pressure on the big cities in South-Holland. We provide better connections between existing and new developments, creating agglomeration power.

Functional connections such as infrastructure, but also cultural connections and connections in knowledge. These connections create a synergy between the cities on multiple scales. We offer the benefits of the inner city through better connections between the cities and new well-balanced developments. More social interaction, good education and job opportunities and the rich range of cultural facilities are offered in the circulabs. In doing so, we ignore the disadvantages of the compact city as less open space, too much crowds, more congestion and pollution and most important less quality of the living environment.

CIRCULARITY AS A LIFESTYLE Individual circular economy starts with responsible usage, upkeep and maintenance of personal items and property. The skills of repair, handicraft are slowly disappearing from society. This is to the benefit of linearly oriented producers, which abuse the inability of the end-users to prolong the life-span of the products themselves. We are focusing on the education of groups such as elderly, which often have time and attitude to maintain the products they own, but dont have the means and assistance to do so. Our envisioned circular lifestyle is closely connected to the DIY movement. Especially the economically disadvantaged groups such as students, starter families or immigrants, are willing to go out of their way to improve their conditions themselves using local resources if they are provided with the capital of knowledge and tools necessary, which they often lack.

NTEREST + The implications of a project of this scale is the involvement of multiple stakeholders. The personal interests of each one could determine the success of the implementation of a project. Currently there is an unbalance of power and interest where the stakeholders with greater power are not necessarily the majority. It is important to know where the stake holders fit within the project and how their position and actions will affect the final outcome. As we can see on the diagram there multiple types of stakeholder and they are portrayed in negative and positive. On the top we have the stakeholders that are important and which we need to attract to prevent a negative impact on the project. On the bottom we have the stakeholders that are interested in the change and that will be happy to adapt, innovate and develop with the circular economy. 64

Public collaborations Knowledge development Lobby

Deploy public task In addition to its own business operations, central government, the province and the municipality also have a policy and administrative role towards the city. These are strong tools to get the circular economy off the ground. Where the government owns land, it can enforce the circular economy through private law. Subsidy schemes also lend themselves to the inclusion of circular requirements. Public collaboration The challenge is to achieve more together and creatively search for solutions within the available rules, in which all governments, NGOs, institutions and related services will work together. Agreements can be made about bundling purchasing power, sharing products and services and exchanging experiences. That would be a strong example signal and it can actually influence the market.

ACTION PLAN AT REGIONAL LEVEL

SHORT-TER

For the regional action plan to realise this synergetic network, we separated different actions and milestones into short-term, mid-term and long-term. Also, for each action and milestone we analysed the stakeholders that are involved. Within the short term it’s about: facilitating local production and creating a better link between local and regional, drawing up material passports, using transformed landscapes for future development and creating decent work opportunities and circular economic growth. Within the mid-term it’s about: realizing adaptable and resilient modular housing, offering workshops about circular construction, increasing the attractiveness of the city as a living environment and realizing housing development through collective private commissioning. For the long-term it’s about getting towards a circular construction and demolition cycle of bio based materials, fore fronting of innovation by experimenting living labs, creating synergy between cities and thereby strengthening the agglomeration power of South-Holland and realizing inclusive living environments by including students, starters and low income housing. 66

The cable district, as activator, forms a place for workshops and meetings focused on innovation in construction and sustainability. With the living labs and maker indystry in Schieoevers new ways of constructing materials are tested and manufactured. Materials from the region are imported in the city hub, then exported to Schieoevers and surroundings. To support a sustainable way of living and working a renawble energy network is laid out. 79

PHASING

PROPOSE changes for the transition towards the milestones A parcel-wise development will lead to more flexibility and adaptability in the future. The high share of self-build and CPO lots and the accompanying selection policy stimulate the realization of circular objectives.

Phase I The cable district functions as an activator and thereby forms the basis for circular development of the area.

Feedback for future housing development in the different circulabs.

At the beginning of area development, establish a consensus on the definition of circularity and circular area development. This is often not yet the case, as a result of which parties do not speak the same language.

IDENTIFY the actors. Analyse the level of influence and interest

BRING the stakeholders at the relevant phases and different scales

ENGAGEMENT STRATEGY DEVELOP communication strategy, COLLABORATE, RESOLVE conflict.

Depending on the requiremets of certain project needs. Plan formulation based on availablity of resources and time period. The municipality closely monitors compliance with the rules and obligations associated with self-construction.

A tender can be written to attract selfbuilders and project developers who are driven to learn more about circularity and eager to apply it in their own home/area development.

Collaboration with the university, research institutes and companies. Advice from the knowledge centers and other experts for designing houses to be circular and modular.

FORMULATE plan of action and devise policy at the multiple scales. ENGAGE stakeholders, GAIN feedback, REFINE approach.

The selection for the lots for regular project development is entirely on sustainability. Self-builders can count on a subsidy if they fit sustainability into their building plans.Organize group meetings in inspiring places to provide information and form a close-knit group.

Phase II First companies are manufacturing flexible and adaptable building materials.

Conservation of diversity is of great importance in the transformation of post-industrial areas. Present initiatives, creative workplaces, culture, etc. are important drivers of transformation and should maintain a place in the area through low rent or phased transformation. Furthermore, measures such as a compulsory percentage for work and social rent can ensure that areas are not developed monotonously.

Delft has a large number of companies, colleges and institutes that could help with the knowledge development of real estate agencies and citizens for future housing. The municipality can organize group meetings in inspiring places to provide information and form a close-knit group.

Current big companies may hinder the redevelopment of Schieoevers. Thereby the rent of new construction is often not payable for existing small entrepreneurs, while they can actually boost an area. The government has a role to play in overcoming obstacles and stimulating where necessary. Figure 5.13| Section of the different flows - Schieovers ; Illustrated by authors

The new manufacturing industry is a driver of innovation in regional value chains and creates above-average new jobs. Collaboration with existing companies and new start-ups is important here. Students, residents and graduates can contribute to this. Investing in talent and idea generation is an important first step in order to subsequently convert the idea into a business. 82
