13. Processamento de cartuchos de impressoras de jato de tinta: um exemplo de gestão de produto pós-consumo
This work presents a route for processing spent ink-jet cartridges in an experimental course. The disassembly of the cartridges requires several steps and the recognition of their different components is essential to define the best final destination (recycling, co-processing). The plastic strips were chemically processed so as to recover gold and copper. Th

15. Alternativas para o Reaproveitamento de Rejeitos Industriais de Poli(tereftalato de etileno) Reciclado / Alternatives for recycling of industrial wastes of recycled poly (ethylene terephthalate)
The production of nonwoven fabrics (NWF) by extrusion process from recycled poly(ethylene terephthalate) (PET) is an interesting way for polymer recycling used by industry which to allow conciliate economic viability with environmental benefits. However, during extrusion step, a fraction of material is lost due to equipment clogging or others factors, leadin

17. O espaço dos resíduos sólidos domiciliares e de sua logística reversa na geografia urbana: diagnóstico e modelo de gestão pró-ativo
The present study investigates the reversal logistic of waste in urban geography and proposes a model of proactive management. As methodological principles, were used bibliographical review, field research and document analysis. In order to reflect this context, concepts like reverse logistic, urban space, selective collection, environment, solid waste, sust

18. Programa de gerenciamento de resíduos químicos do CENA/USP: avaliação, ações de aperfeiçoamento e de extensão / Chemical waste management program of CENA/USP: assessment, improvement and extension actions
The generation of chemical waste in industry is very high, therefore the effluent discharge has been monitored by environmental inspections with greater intensity, to avoid environment contamination. The volume of waste generation is very small in universities, but the diversity is too large, what makes the treatment more difficult. Nevertheless, there are a

19. ANÁLISE E PROPOSTA DE DIRETRIZES PARA UM SISTEMA LOGÍSTICO DE RECOLHA E BENEFICIAMENTO DOS RESÍDUOS SÓLIDOS PARA ÁREAS DE FAVELA EM SINTONIA COM OS PRECEITOS DO GRSCM / ANALYSIS SCOPE AND GUIDELINES PROPOSAL OF A COLLECTION AND TREATMENT LOGISTIC SYSTEM FOR SOLID WASTE IN SLUMS AREAS IN HARMONY WITH GRSCM PRECEPTS
O gerenciamento de resíduos sólidos tornou-se um tema de preocupação para administradores públicos de todo o mundo. O aumento no nível de consumo, somado ao uso indiscriminado de materiais descartáveis, despertou na opinião pública movimentos que cobram das empresas uma nova postura referente à preservação dos recursos naturais. O Green Supply Ch

20. Mechanical characterization using optical fiber sensors of polyester polymer concrete made with recycled aggregates
The sustainable management of solid wastes encourages metallurgic and metal-mechanic industries to look for safety applications for their wastes, thereby attenuating the environmental impact or lowering the costs. The study herein proposes strain monitoring the recycling of foundry sand with organic pollutants, as inert, in the manufacturing process of polym

21. Statistical design for recycling kaolin processing waste in the manufacturing of mullite-based ceramics
Mineral extraction and processing industries have been cited as sources of environmental contamination and pollution. However, waste recycling represents an alternative recovery option, which is interesting from an environmental and economic standpoint. In this work, recycling of kaolin processing waste in the manufacture of mullite-based ceramics was invest

23. Editorial
Numerous silicates based wastes have been produced and considered for recycling and reuse. Among them, glass cullet is one of the most common silicate wastes and has considerable volume in the cities wastes. A big amount of this waste is recycled by the glass industry but another part is dumped in the cities garbage deposits. In the last few decades there ha

24. Evaluation of the feasibility of reintegrating post-consumer PET into production / Avaliação da viabilidade de reintegração de resíduos de PET pós-consumo ao meio produtivo
Entre os materiais presentes nos resíduos sólidos domiciliares, os resíduos poliméricos pósconsumo representam cerca de 27% do volume total da coleta convencional, segundo Matos (2006), com o agravante da degradação lenta, comprometendo a vida útil dos aterros sanitários e poluindo o meio urbano. Dos resíduos poliméricos, destaca-se o Poli (tereft
