Description du projet
Une révolution circulaire pour la gestion des déchets urbains
Le rapide développement des villes s’accompagne d’une demande croissante d’énergie, de nourriture et de systèmes efficaces de gestion des déchets. Dans ce contexte, le projet DECISIVE, financé par l’UE, ambitionne de transformer la gestion des déchets urbains en une économie circulaire. DECISIVE entend répondre aux impacts logistiques, environnementaux et sanitaires de la gestion des déchets dans les zones urbaines grâce à des solutions innovantes, telles que des réseaux de gestion décentralisés et des processus de fermentation éco-conçus. Ce changement de paradigme favorisera l’intégration entre les zones urbaines et périurbaines. Le projet entend passer d’un système de déchets dépendant des importations et géré de l’extérieur à un réseau coopératif permettant la valorisation décentralisée des biodéchets. L’approche globale du projet promet de révolutionner la gestion des déchets au profit des villes en expansion du monde entier.
Objectif
The growing attractiveness of cities leads to increasing population, thus rising energetic and food demands in urban areas. This makes urban waste management increasingly challenging, both in terms of logistics and environmental or health impacts. To decrease the cities’ environmental impacts and to contribute to a better resilience of urban areas towards energy or food supply crisis, waste management systems have to be improved to increase recycling of resources and local valorization. In this context, the DECISIVE project proposes to change the present urban metabolism for organic matter (foods, plants, etc.), energy and biowaste to a more circular economy and to assess the impacts of these changes on the whole waste management cycle. Thus, the challenge will be to shift from a urban “grey box”, implying mainly goods importation and extra-urban waste management, to a cooperative organization of intra- and peri-urban networks enabling circular local and decentralised valorization of biowaste, through energy and bioproducts production. Such a new waste management paradigm is expected to increase the sustainability of urban development by: (1) promoting citizens awareness about waste costs and values; (2) promoting renewable energy production and use in the city; (3) developing an industrial ecology approach that can promote the integration between urban and peri-urban areas, by providing valuable agronomic by-products for urban agriculture development and so improving the balance of organic products and waste in the city; (4) developing new business opportunities and jobs. In order to achieve these objectives, the project DECISIVE will develop and demonstrate, at real scale, eco-innovative solutions addressed to waste operators and public services, consisting in: (1) a decision support tool to plan, design and assess efficient decentralised management networks for biowaste in urban areas; (2) eco-designed solid-state fermentation processes. Moreover in parallel of real scale demonstration sites, an eco-designed new micro-anaerobic digestion process will be developed and tested.
