circular economy for a circular city

The main goal of this work is to show the good practice and policies to adopt to make the urban system more similar as possible to a natural system. Starting from a short analysis of the concept of urban metabolism and its historical evolution, analysing the Europe situation, with the guide lines from the Sume Project, and having a quickly overview of the Italian situation and its soil consumption policies, I'll go throught the concept of circular economy. I'll focus my attention on the practices to adopt to implement this concept within an urban area, considering economical, social and technological aspects driving the switching from a linear economy to a circular one. In the last chapter I'll analyze in depth the study case of Buiksloterham, an industrial district in the north of Amsterdam, for which Metabolic, an environmental and sustainability consulting firm where I had my internship, with the collaboration of other firms and the municipality, is trying to design a new development model that fallows the urban metabolism and circular economy principles. The project is going to be developed and has a long term prospective that has the goal to make the Buiksloterham a world exemple for self sufficiently and sustainable practices by 2034. Specifically I will analyze the project phases that now have been developed, starting from an urban metabolism scan, usefull to account the present flows of the district and to create a +20 scenario if a business as usual is mantained, then moving to the vision created with the stakeholders collaboration and to the goals to be achieved immediately, in short and in long period. Finally I will analyze the action plan that will be proposed to the stakeholders with a list of sistemyc and tecnical intervetion to realize the circular Buiksloterham fallowing the energy efficiency and self sufficiently , the nutrient and wastewater recover and complexity mantainance principles . these kind of intervention are usefull and necessary to create value and motivate all actors (with a direct and indirect stake) partecipation. I will highlight how a kind of project like this is possible with an high burocracy an amministration elasticity and a comunity, firms and municipality collaboration. In this work will be highlight many times the importance of the pubblic partecipation and the stakeholders implication to reach an efficient and effective eco-sustainable develop of the urban structure. The integration of different practices and the creation of appropriate financial instruments that stimulate the change and drive people's behaviors, creating value by saving the natural capital, are principles that will have a big relevance. Another aspect that will have great importance will be the manteinance of complexity and then of biodiversity that is necessary to ensure the systemic resilience. It will be highlight the necessity to put in practice an environmental education in the school apparatus to create awareness specially in the younger generation.
