143 SUSTAINABLE WASTE MANAGEMENT AND CO 2 - BASED URBAN PLANNING FOR MOLINS DE REI Miguel Rami, Elisabeth Terrisse, and Roberta Sinestesio Studio Carles Crosas and Jorge Perea (ETSAB) IN-BETWEEN Molins de Rei is a place where a lot of people pass through but very few arrive. Its geographic location within the framework of the Barcelona metropolitan area has forced it to deal with the massive fluxes between Barcelona City and all the territory that is connected to it through this channel. Train lines, highways, and electrical towers have been set up in this area along the river, framing it and separating it from the natural surroundings and from the adjacent population nodes. All this infrastructure has come to define the landscape and is not expected to move or disappear but to keep growing. Molins de Rei has to confront the same challenges that big metropolises will face, albeit with fewer inhabitants and therefore with fewer economic resources. So what is the path to follow for the future of Molins de Rei? What a metropolitan-scale analysis of Molins de Rei reveals is its importance as the southwest portal of Barcelona for goods and energy and its nodal importance in the waste management network. Our proposal is faced with a double objective. On one hand, our task is to reconcile this town with its great natural surroundings— the nearby mountains of Collserola and Garraf, the Llobregat River—and also to strengthen its historical bonds with the neighboring communities, thus improving accessibility. And on the other hand, our task is put to use residual management infrastructure existing in the area to meet one of the biggest challenges for the metropolis of the future: an environmentally sustainable waste management of urban territories. WASTE MANAGEMENT PROCESS: W2E, W2M, 3R Today, we find ourselves in the Anthropocene geological epoch. Its main characteristic is that human behavior directly, and in ways that we can perceive, affects all the ecosystems in which our activities take place. Desertification, rising temperatures, or the pollution of the seas with plastic are some of the global effects directly related to waste management. The most complex aspect of these problems is not so much finding a technical and organizational solution, but the fact that a complete, profound revision of the way in which we conceive of, identify, and understand waste is necessary, and of how our way of life affects it. Nowadays, Spain recycles 30% of the waste that it generates. According to the statistics, we are only half as successful as Germans when it comes to recycling and considerably
