Este trabalho discute o uso da análise de frequência de moscas das famílias Calliphoridae e Muscidae na avaliação do impacto da implantação de programas de coleta seletiva de lixo urbano. Para isto, utilizou-se do estudo de caso de Tupã, município paulista, em duas fases distintas: fase 1 - compreendida entre os meses de junho e outubro de 2001, período caracterizado pela presença do lixão e; fase 2 - entre os meses de novembro de 2001 a maio de 2002, caracterizada pelo início da implantação do processo de coleta seletiva e reciclagem e aterramento gradativo do lixão. Procedeu-se a captura dos insetos com dez armadilhas confeccionadas com garrafas plásticas, de dois litros, do tipo PET, alocadas em residências e árvores ao redor do lixão. Como atrativo utilizou-se aproximadamente 400 ml de vinhaça de cana de açúcar, substituída semanalmente no ato da colheita. Nas duas fases da pesquisa, observou-se que a família mais frequente e constante foi a Calliphoridae.  Houve correlação positiva, antes da coleta seletiva, entre o número de califorídeos e a precipitação pluviométrica (0,638) e, entre o número de muscídeos e a temperatura média (0,605). Após a coleta, o mesmo não foi observado. O programa de coleta seletiva implantado nesse município paulista resultou em diminuição significativa na frequência de dípteros e a análise da flutuação de califorídeos e muscídeos demonstrou-se como um eficiente indicador de monitoramento da qualidade ambiental.

Among numerous studies about the selective collection of solid waste and cooperatives of recyclable materials, this research aims to contribute with the study of these problems from the geographic space. As the world population increases, the issue of solid waste becomes increasingly worrying, due to new consumption patterns that create larger amounts of waste, especially in the urban centers. The recycling appears to be the best solution for this problem since most materials that are currently sent to landfills would become raw material for new products. The Triage Centers performs an important role in this process because they are responsible for sorting, packing and selling the materials arising from the selective collect, so it is necessary to analyze the places where these steps are performed. This study intend to examine the location and distribution of these enterprises in the city of São Paulo in order to provide support for the mitigation of impacts, both environmental and social, from their location, as well as provide support for the expansion of selective collection program in the city. The choice for studying this area was due to the curiosity of investigating the inefficiency of the recycling program in the city of São Paulo, which currently recycles about 1% of all household solid waste collected. Therefore, from a historical survey of the city's recycling programs, technical visits, interviews with responsible agencies and also analysis of the Triage Center's frameworks based on the guidelines from the municipal legislation, it will be evaluated the problems faced by the program for its expansion

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.

The research aims to propose grants for development of Municipal Plan for the Management of Organic Solid Waste generated in the municipality of Rio Claro. The research universe was composed of organic waste generators establishments (markets and grocers). From the registry of commercial establishments provided by the municipal government were identified who presented this typology, which totaled 38 establishments. In this universe the interview was conducted in 15 establishments obtained by directed sampling based on the characteristics of size, type and location. The data collected were the amount generated, disposal of waste, waste separation, collection frequency, reasons for the disposal of waste, frequency of purchase of products. From the data obtained in the field, we estimated the total generation of organic waste in this segment for the municipality. Then, the estimated costs for implementation and operation of a composting center, a way to subsidize the implementation of the management plan was carried out. We opted for the aerobic composting process by the simplicity of operation and because it is a technique already known. The average waste generation was established by tracks (size) with: stores up to 4 boxes (classified as small) generate on average 1511 kg / month, 40% of organic waste, the 5-9 boxes (small/midsize) generate on average 4338 kg / month, 35% organic and the 10 to 19 boxes (midsize) generate on average 7647 kg / month with 32% organic. In total establishments generate 105 t/ month of waste, with 35t / month of organics. 94% of establishments are in font segregation of waste into recyclable, organic and waste, indicating that the proposed management of organic waste is amenable to application without many changes in existing routine in stores. Recyclables are sent for recycling through selective collection held by the cooperative, while the organics are destined for the landfill and feed. The results indicate...
