Valorization and Reuse of Materials for the Circular Economy


Valorization and Reuse of Materials for the Circular Economy


The construction and infrastructure sector annually produces 260 tons of non-dangerous waste, being 70% of the waste generated in France. The recycling of this waste is at the heart of national and European legislation and more particularly the objectives set by the Directive 2008/98 / EC on waste, and the energy transition law for green growth of August 2015. The reuse of waste is fully in line with the concepts of the circular economy linked to sustainable development and the preservation of the environment. The application of the circular economy principals for the good management of waste allows the maintenance of secondary resources in the production circuit and the preservation of primary natural resources. As part of this event, international researchers and engineers come together to present innovative and economic case studies focusing on the main challenges and opportunities in the cycle of recycling, recovery and reuse of waste in the field of Construction.

Valorisation et Réemploi des Matériaux pour l’Économie Circulaire


Le secteur du BTP produit annuellement 260 tonnes de déchet, rarement nocifs, soit 70% des déchets générés en France tous secteurs confondus. Le recyclage des déchets du BTP est au cœur de la réglementation nationale et européenne. L’ensemble des professionnels du secteur du BTP visent à atteindre   les objectifs fixés par la Directive-cadre Déchets 2008/98/CE et la loi de transition énergétique pour la croissance verte d'août 2015 et ambitionnent de répondre aux concepts de l’économie circulaire liés au développement durable et à la préservation de l’environnement. L’application des principes de l’économie circulaire pour la bonne gestion des déchets permet la maintenance des ressources secondaires dans le circuit de production et la préservation des ressources naturelles primaires. Dans le cadre de cette manifestation, des chercheurs et des ingénieurs internationaux se réunissent pour présenter des études de cas innovantes et économiques en se concentrant sur les principaux défis et opportunités dans le cycle de recyclage, de valorisation et de réutilisation des déchets dans le domaine du BTP.
