The energy transition is a complex challenge for cities. All sectors of society will have to change. Many sustainable opportunities arise, but injustices are still present. Often, people in disadvantaged positions are not properly recognized, included in decisions and left to deal with the burdens. Lack in proper citizen participation, causes current energy transition policies to appear distant from the local, implementation scale. Using socio-economic, spatial analysis and governance mapping, this project showcases energy vulnerabilities and the skewed institutional perspectives on local transition capacities. By combining expert interviews, policy analysis and imaginative co-creation sessions in the case study area of Hillesluis, Rotterdam, a more just governance structure and inclusive participatory practice can be formed. The project exposes injustices in underlying systems of power and decision making, as many policy incentives are aimed towards financial benefits. The current participatory process of transitions in itself is characterized by ex-ante responses and informs rather than actively engages communities. This results in many citizens who are in disadvantaged positions, albeit financially or socially, are left out. Thus keeping loops of injustice in place. Through theoretical and co-creation experimenting, a just participation process was formed, however the execution therein showcased many difficulties. Measures such as frequent city-wide campaigns, transparency and adaptive area-based strategies could divert these fragilities in participatory processes for future sustainable transition research. As socio-technical transitions are becoming more complex, innovative perspectives and empirical research are needed. This project not only critically examines current governance structures and participation processes, but proposes measures to overcome the experienced socio-spatial and procedural barriers towards just energy transitions. Resulting in more human-centred and socially innovative policy aims towards a just energy transition for all.

Different government bodies, from the European Union down to the Port of Rotterdam Authority have implemented the policy goal to become circular by 2050 to minimize demand and dependence on finite resources. However, a circular economy - an economic model in which materials circulate in closed loops and waste is viewed as a resource - is vastly different from the current linear system of extraction, consumption and waste. The plastics industry that is currently present in the port of Rotterdam is one such industry where large amounts of raw material is being used and large amounts of waste generated. It is still far from circular. Thus, transitions in the industry itself and in our interaction with products are necessary. The question that arises is: how can the transition to circular plastic manufacturing in the Rotterdam maritime region contribute to a more sustainable, resilient and just economy?

Theory on transition management and socio-technical systems, analyses of spatial use and networks of the plastics industry in South Holland, and research on the developments in plastic manufacturing, has led to the understanding of the current networks and flows in the plastics industry. A subsequent analysis of stakeholders, policies and design options has led to a vision and strategy for the South Holland region, on how to shape a new circular plastics economy.

In the proposed strategy of Plasticity, (1) the strength of a strategic location in the port of Rotterdam is used to expand the renewable cycle of the bioplastics industry, and (2) by actively engaging citizens in reusing and recycling plastic products on a local level in the whole region, a technical circular cycle is enhanced in the whole province. Plastic is used as an example to demonstrate the contemporary issues around dependency on fossil material in the South Holland context, but similar principles regarding integrating the biological and technical cycle, facilitating space for innovation and growth of circular models, and engaging the whole socio-technical system in the transition process can be applied to other sectors and places. This expands the applicability of this vision and strategy beyond plastic.
