A aprovação e posterior regulamentação da Lei 12.305, de 2 de agosto de 2010, que institui a Política Nacional de Resíduos Sólidos – PNRS estabeleceu necessidades de uma nova articulação entre os três entes federados – União, Estados e Municípios – o setor produtivo e a sociedade em geral na busca de soluções para os problemas atuais na gestão de resíduos sólidos. Baseada principalmente no conceito de responsabilidade compartilhada, toda a sociedade – cidadãos, setor produtivo, governos e sociedade civil organizada – passa a ser responsável pela gestão dos resíduos sólidos por ela produzidos. Falando especificamente do cidadão, um dos atuais desafios é saber como seu comportamento em relação à separação de resíduos recicláveis no âmbito do seu domicílio se relaciona com os objetivos e metas de reciclagem do município. Considerou-se uma amostra (N=310) de residentes em domicílios do Rio de Janeiro, e os dados coletados foram analisados segundo o modelo ABC de STERN. Os resultados empíricos mostraram que as variáveis associadas ao hábito, às normas sociais diretas e às atitudes afetivas têm peso significativo na predição do modelo do comportamento pró-reciclagem. Como contribuição prática, espera-se que o PMGIRS do Rio de Janeiro possa ser aprimorado, contribuindo para o aumento da participação do cidadão na separação de resíduos recicláveis em seu domicílio, auxiliando os gestores municipais nas decisões necessárias ao cumprimento de objetivos e metas relacionados com a reciclagem na cidade do Rio de Janeiro.

The issue of waste, historically, has been getting worse as a result of the world´s population increase and in order to meet their needs the consumption of natural resources and the generation has been constantly increasing, especially in large urban centers. The people involved in the collection of recyclable solid waste, called from now on as collectors, are responsible for about 90% of the waste sent to recycling industry in Brazil. Apart from having a role in the economy, the collectors have specific knowledge and skills necessary to identify, collect, sort and sell these wastes. This study aims to examine the possibilities and limits of COOPERVIVA – Cooperativa de Trabalho dos Catadores de Material Reaproveitável de Rio Claro - as an instrument of the municipal solid waste management system, and its experience as a recyclable waste collectors cooperative. The methodological procedures of this study rely on the literature research on the experiences of cooperative and the management of municipal solid waste. In addition to this review of the literature, fortnightly visits to the cooperative were held in order to experience their daily activities, and testimonies of the cooperative members were collected as well as documents and reports produced by COOPERVIVA. The results of this analysis are considerations of the limitations of the cooperative and recommendations aimed at maximizing their potential as a tool of the domestic solid waste management system of and as a recyclable waste collectors cooperative. Among other things it can be concluded that the urban selective collection of waste challenges the community to the reinvention of life and the relationships each individual with the planet.

An alternative system was tested for the determination of CO2 in air using recyclable materials. The results indicate that the proposed system allows for reliable, accurate, robust and efficient collection, comparable to the standard gravimetric method. Laboratory wastes are easily treated using a filtrate that can be discharged into the sewer and solids that can be reused. The proposed system is a simple and low-cost tool that encompasses important aspects of environmental education, which should be part of the education in chemistry of undergraduate students and technicians.

This dissertation conducted in the years 2011 and 2012, an analysis of cooperatives waste pickers in the city of Natal, Rio Grande do Norte, aiming to identify improvements to be implemented to assist the management of waste from the municipality as well as to improve the living conditions of the workers who perform the selective collection, the environmental perspective. This analysis was performed by means of an investigation of the reality in which they live cooperatives and their local representation, using also the law. The research is characterized as a case study of an applied nature, documentary, consultations with the institutions related to the issue of solid waste in the national and local levels; exploratory and descriptive, the main methodological tools technical visits and structured interviews. From these methods was possible to obtain data regarding the organization of cooperatives, environmental perception of the collector of recyclable materials, among other issues. For the analysis of data matrices were used to include comments and method GUT, from which it was possible to identify numerous difficulties faced by recycling cooperatives, and develop proposals for possible improvements in various aspects of their operation, such as infrastructure and production process , which can improve both the waste management and the quality of life of workers involved in the selective collection system city
