Dynamiques des filières de récupération-recyclage et écologie territoriale : l'exemple de la filière de traitement des déchets d'équipements électriques et électroniques (DEEE) en Midi-Pyrénées / Recovery-recycling chain and industrial ecology : an example of Waste Electrical and Electronic Equipment (WEEE) treatment in Midi-Pyrénées (France)

Le contexte de la gestion des déchets est soumis à des orientations politiques changeantes qui se font l’écho, d’une part de la volonté de préserver les ressources, d’autre part, de l’avènement de l’écologie industrielle. Pour aborder ces enjeux, cette recherche, conduite à l’interface entre sciences de l’ingénieur, sciences sociales et sciences du territoire, s’intéresse plus précisément aux dimensions technico-économiques, sociopolitiques et spatiales des filières de récupération-recyclage. Elle aborde la manière avec laquelle est favorisé le développement territorial de ces filières, en se focalisant particulièrement sur la filière des déchets d’équipements électriques et électroniques (DEEE). Elle s’interroge sur la contribution du système local de recyclage au développement des démarches d’écologie industrielle. Elle s’appuie notamment sur l’analyse systémique de la mise en oeuvre de l’opération de récupération-recyclage des DEEE en Midi-Pyrénées.Cette recherche montre comment l’objet DEEE met à l’épreuve la territorialisation de la réglementation européenne et française de la gestion des déchets. Basée au départ sur une étude quantitative des flux de matières et d’énergie de la filière, la question se déplace progressivement vers l’étude qualitative des divers positionnements du système d’acteurs qui pilotent le métabolisme de la filière. / Legislative frameworks of waste management are impacted by resource management and industrial ecology’s paradigm. Considering this issues through engineering science, social sciences and regional planning, this work focuses on technical, political and spatial dimensions of recovery-recycling chain. It aims at analyzing its regional development, through the example of the treatment of Waste Electrical and Electronic Equipment (WEEE). It reveals how local recycling system contributes to the development of territorial ecology, while focusing on a systemic approach of WEEE recovery and recycling in Midi-Pyrénées (France).This work shows how WEEE’s management interacts with European and French legislative frameworks. Based on a material flow analysis of the recovery-recycling chain, this study shows the strategic issues of the chain’s metabolism which results from the dynamics of the various organizations involved.

Mudanças no atual papel do catador de materiais recicláveis na cadeia de gestão integrada de resíduos, em face das políticas públicas para o setor em um estudo de caso / Changes in current waste picker´s role in the integrated waste management chain, facing the public Brazilian policy for this sector in a case study

No Brasil, a gestão e destinação de resíduos sólidos são problemáticas e podem ter grandes melhoras com o cumprimento das diretrizes da Política Nacional de Resíduos Sólidos (PNRS). Esta Política aponta para os princípios da Gestão Integrada de Resíduos (GIR), que indica diversificação no tratamento e disposição final como última alternativa. Uma ferramenta importante na GIR é a reciclagem, que no Brasil se estruturou com base no trabalho do catador, fragilizado na Cadeia Produtiva de reciclagem, não possuindo profissionalização equiparada com os outros membros. Verificada a situação de responsabilidade delegada aos catadores no futuro da Gestão de Resíduos sólidos e sua condição atual, no contexto de uma associação de catadores, constatou-se que os agentes se consideram em posição desigual dentro da Cadeia, e apresentam a necessidade de melhorar a comercialização e percebe-se esta Cadeia de Reciclagem comprometida neste ponto. Isto se verificou porque a estrutura da associação era limitada em vários aspectos. A PNRS atribui grande importância aos catadores, que aqui não dariam conta de coletar os resíduos, isto pela necessária melhora da gestão. Há também o fato de que alguns materiais não são de interesse do catador, considerados inviáveis. A reciclagem de certos materiais não ocorrerá naturalmente, sendo necessário algum tipo de intervenção. / In Brazil, management and solid waste disposal are problematic and can have major improvements to compliance with the guidelines of the Brazilian National Policy (PNRS), that points to the principles of the Integrated Waste Management (GIR), which indicates waste treatment and disposal diversification and final disposal as the last alternative. An important tool in the GIR is recycling, which in Brazil is structured based on the work of the waste picker, weakened actor within the Recycling Production Chain, which has no professional capability as the other members. Verifying the situation regarding the responsible delegated to the waste pickers in the future of the solid waste management, and its current condition, in a waste pickers association, It was found that the collectors consider themselves in an unequal position within the chain, and have need of commercial relations improvement. Upon the lack of equivalent professionalism of the waste picker with the other levels, it is clear that the recycling chain is committed at this point. This occurred because the structure of the association was limited in several respects. The PNRS assigns great importance to the collector, that here were not going to collect all the waste, because there is necessary improved in management. There is also the fact that there are some materials that they do not work for its non-viability. It was found that the recycling of certain materials will not occur naturally, requiring some type of intervention.
