Estudo da viabilidade econômica da implantação de incineradores de RSU na Região de Bauru

A principal preocupação relacionada à produção de resíduos tem sido o manejo e a gestão integrada, procedimentos que passaram a fazer parte das políticas de gestão com o objetivo de evitar problemas irreversíveis ao meio ambiente e aos seres humanos. Neste trabalho estuda-se a possibilidade da incineração dos Resíduos Sólidos Urbanos (RSU) como solução para o problema relacionado com a destinação dos resíduos gerados na Região de Bauru. Estimar os custos de capital e a viabilidade econômica para o projeto de incineradores de larga escala é uma tarefa prioritária para auxiliar o processo de tomada de decisão. Este trabalho revê a situação dos resíduos sólidos na região de Bauru e realiza revisão dos processos empregados e existentes no tratamento dos RSU com o objetivo de analisar a viabilidade da implantação de uma usina de incineração com geração de energia elétrica para o tratamento dos resíduos sólidos coletados na Região de Bauru. O estudo apresenta um retorno interessante ao passo que as simulações apresentam indicadores favoráveis a sua implantação.

Life cycle assessment applied to municipal solid waste management: a case study

This study analyzes the environmental performance of the Municipal Solid Waste Management System (MSWMS) of Piedade, São Paulo, from a systemic perspective. A life cycle assessment (LCA) technique was applied according to an attributional approach to evaluate both the current operational situation and different prospective scenarios, which were devised based on the application of targets for recycling dry and wet waste suggested by the pre-draft version of the Brazilian Plan for Solid Waste. The life cycle impact assessment method EcoIndicator 99, in association with normalization and weighting procedures, was used to conduct the analysis. It was observed that the adoption of goals of 30%, 50% and 70% for recovering of the recyclable dry waste, resulted in improvement of the environmental performance of the waste management system under analysis, respectively of 10%, 15% and 20%. It was also possible to detect an evolution in the order of 54% in reducing impacts resulting from the adoption of targets for composting. LCA proved to be effective for the evaluation of the environmental performance of MSWMS-Piedade. However, for future evaluations, the attributional approach should be replaced by the methodological practice of substitution to enable the avoided burdens to be considered in estimations of the environmental performance municipal solid waste management systems.

Potencial de contribuição e importância socioambiental dos 'catadores autônomos' de Rio Claro (SP) para o programa de coleta seletiva municipal

The Urban Solid Residues are the rests of human activity, popularly known by trash and considered by population like useless, undesirable and disposable. On the other hand, for the waste pickers, solid residues are the beginning of a cycle: they see in the other's people trash the only income, an economic value. Currently, in brazilian cities, one million collectors act, alone or in cooperatives, socially excluded by the work they do. The National Policy of Solid Residues (PNRS), instituted in 2010, established guidelines to the execution of integrated residues management, with should be practiced by city halls and other governmental institutions. This policy has, besides other things, goals of residues reduction and inclusion of waste pickers in the mechanism of selective collect and recycling. However, this and other public policies created for residue management are benefic only for cooperated waste pickers. That could negatively affect most of this class, since 90% are waste pickers working in a precarious way on the country's streets. This study has for objective show that most of waste pickers that work in a precarious way on the brazilian territory has a huge potential for the solid residues recycling chain and how they should be valued for the environmental services they provide, so they can be included with dignity on the society, ensuring economic and social benefits for this workers. The methodology adopted was based on the amount of residue collected by the 44 cooperated members of the Rio Claro‟s waste pickers cooperative to estimate the potential of collect and recycling did by 210 autonomous waste pickers who are active on city streets. It was observed that the cooperative collects the equivalent of 10.2% of all recyclable residues generated by city population. However, with the potential that these autonomous waste pickers have, which together could contribute 465 tonnes of solid residues per month, or 5,570 tons a year...

Cooperviva: análise das possibilidades e limites do trabalho dos catadores de resíduos recicláveis de Rio Claro (SP)

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.
