The complex relationship between humans and the natural world is still visible in 2023s urban planning: a city is a place for humans, and nature gives space to all non-human species. The anthropocentric perspective within the urban environment puts humans above non-human nature. This is also the case within urban renewal in the Netherlands, which aims to improve human liveability. This aim is reflected within the ongoing urban renewal in Carnisse, Rotterdam, the Netherlands, under the leading plan of NPRZ as well. However, considering non-human species might have positive effects for both human and non-human species. This thesis addresses the research question: "How can values of ecological justice contribute to a spatial design that improves urban renewal in Carnisse, Rotterdam?" to investigate the impact of non-human species liveability on urban renewal concepts and spatial plans in Carnisse. The study conducts a systematic liveability analysis of several target species representing circa 80% of the species currently present in the neighbourhood. Based on the analysis, a toolbox is developed, which is the foundation of integrating human and non-human demands within urban renewal. With a combination of consideration of the existing structure, context consideration, the implementation of zoning, biocentrism and nature-inclusive thinking, the translation towards a spatial plan based on ecological justice values for the neighbourhood Carnisse is created. Comparing the current NPRZ urban renewal plan and the ecological justice values-based plan reveals that if ecological justice is included, the concept of urban renewal should be revised and that there is a case for a more integrated approach to the physical and social domain within urban renewal. Besides, the focus on ecological justice values might reduce the in-depth focus on human liveability compared to the approach to urban renewal. Nevertheless, the spatial outcomes of the focus on non-human liveability will (indirectly) positively affect human liveability by improving health, lowering crime rates, improving interaction between humans and non-human species, and increasing climate adaptation of the area. Therefore, implementing ecological justice values will improve urban renewal concepts and spatial plans from an Arcadian perspective by improving the non-human species' liveability and from a resource standpoint, by improving human liveability.

Nowadays, circular economy is of growing importance in the social, economic, and environmental fields. The realisation happens on different scales. First steps towards a circular economy have already been taken, but it will take time before a circular world is reached. Also, under the Sustainable Development Goals (SDG), the bio-based concept raises more awareness.

This strengthens the aim to create a circular economy. The industry in the Port of Rotterdam is mainly based on fossil-based industries that follow the linear system. Therefore, high emissions and waste are caused. This contradicts the aims of the SDG and the idea of a circular system. Consequently, the port area should be transformed into a flexible system that can adapt to changing future situations. This will be realized by a circular system that contributes to the development of the bio-based industry.

This transition is triggered by the current oil- and plastic industries taking place within the Port. By treating the bio-plastic industry as a trigger industry, a strategy for the transition towards a bio-based system is created. This leads to a circular economy that depends on bio-based materials. Since the bio-based system might face future challenges, it is important to guarantee further adaptation and self-improvement over time. The final goal is to create a closed-loop within the Port region to reduce emissions and waste products using these bio-based materials.

To close this loop, the Bio-Loop ZH2050 is integrated into the Port area. A Green Belt strategy promotes the circular economy within the province of South Holland, and by implementing the Living Labs, knowledge and technologies are improved over time. The Bio-Loop ZH2050 influences the aim of the province to become 100% circular by 2050 and several SDG topics. Environmentally, this project supports the transition towards a circular bio-based system and to reduce the impact of pollution and climate change. Socially, the Bio-Loop ZH2050 creates the possibility to get society involved in the bio-based circularity. And finally, economically, the Port of Rotterdam will become the port of Europe based on the bio-based economy, which is the entrance connecting the global market and EU market.
