Este artigo traz os resultados de uma pesquisa descritiva realizada na Região do Grande ABC, e ele se justifica em virtude da responsabilidade do poder público no tocante à gestão dos Resíduos Sólidos Urbanos (RSU), especialmente a partir da Lei nº 12.305/2010, a Política Nacional de Resíduos Sólidos. Objetivou-se descrever e comparar as práticas de gestão dos RSU adotadas pelas sete prefeituras dos municípios que integram a região. Foram realizadas 17 entrevistas com pessoas do poder público e cooperativas envolvidas com a gestão dos resíduos. Os dados foram analisados por análise de conteúdo. Concluímos que a coleta seletiva caminha a passos lentos na maioria dos municípios, no tocante à implementação e institucionalização. Os representantes das cooperativas manifestaram que a dependência do poder público e a mudança de governos interferem diretamente no desempenho da coleta seletiva, pois precisam se adequar a cada troca de governo, podendo provocar descontinuidades ou paralisações.

The present work is the analysis of the practices and techniques currently used in the final allocation given to organic household solid waste in the city of Rio Claro - SP. As the major part of Rio Claro’s household solid waste is formed by the organic fraction, as well as in the rest of the country, this research proposes a study on what is done with that portion of the waste, its treatment and where finally destined, based on the National Solid Waste Politic, recently approved in 2010. With the use of this organic part, for example: as animal feed supplement or compost embodiment for the purpose of producing organic fertilizer, enables the decrease of the percentage of the total destined to dumps and landfills. This total percentage has already been reduced after the popularization of the beneficial recycling programs in Brazil, which are still growing. As cities and the purchasing power of its individuals grow, there is also a consequent growth of waste production by society. The household whether domestic solid waste are lower than Industrial Solid ( RSI ) waste for the production in million tons ( Mton ) quantities , however, those residues are more visible on a daily basis - in cities and periphery as well, due to the inadequate management, - and also offer , as well as industrial and agricultural wastes , several types of harmful effects to the population when managed incorrectly. Therefore, the research aims to assist in the study of Solid Waste Management (MSW) for efficient Urban and Environmental Planning in a midsize city. Thus, this project aims to analyze in the city of Rio Claro, how the allocation of these materials is done and whether these practices denote effective improvement regarding the proper management of waste, in the same way that the recycling chain would allow this effect

The objective of this study was to analyze the performance of solid waste management in the municipality of Tibagi, Paraná, a city with approximately 20000 inhabitants, which implemented the selective collection program called Recycle Tibagi. The analysis was based on descriptive statistical techniques, considering the three types of waste (tailings, organic and recyclable), and per capita generation of garbage upward trend in the coming years, based on the method of Winter (Triple Exponential Damping), using data recorded by the Department of the Environment and the Association of Recyclable Materials from Tibagi - ACAMARTI. Efficient selective collection from a structured environmental education program with constant training conducted with the scavengers, possible to obtain important data in sorting and marketing of recyclable materials, saving raw materials, water and energy, as well as relevant indicators social inclusion and employment generation and income. The project involves several areas of municipal management and arouses curiosity and interest in several areas: social, financial, environmental and administrative. It's a way to encourage new projects and public bodies, highlighting the importance of recycling and proper disposal of solid waste.

Nowadays the rapid growth of urban centers, the accumulation of social and environmental demands, the relationship between public policy and increasingly complex problems accentuates the feeling that cities undergo an urban crisis. This crisis is especially characterized by its multidimensionality, which goes through economic, cultural, ethical, environmental and, above all, political issues. In order to study the core of this crisis that is manifested by the urbanization process and has in its exacerbation on the metropolitan areas was conducted conceptual and theoretical study of the meaning of sustainable development applied to the everyday reality of cities, extracting from this debate concepts, such as: sustainable territorial development, administrative sustainability and political sustainability. Looking forward to test this the practical applicability of these theoretical concepts studied, an empirical study was done on the reality of metropolitan solid waste in Natal, Rio Grande do Norte, Brasil. According to the recent theoretical debate, the waste comprises a sector of the urban environmental crisis that best represents the relationship between man and environment. Ensuring the multidimensionality of environmental issues through the “Saber Ambietal” (LEFF, 2005), was made a extensive qualitative study correlating the concepts of sustainable territorial development, metropolitan governance and “Saber Ambiental” applied on solid waste. The results point to the real challenges of municipal government in understanding the real situation, take action and change the inertia in which have operated in recent decades. The results also showed the importance of transforming environmental issues in political, in other words, struggle for ideas, ideological and ethical references.

Tendo em vista o crescimento das cidades e aumento da população, temos um aumento do consumo, principalmente pelas parcelas da sociedade que possuem maior poder aquisitivo, fato que tem como conseqüência o aumento da quantidade de lixo gerado. Dentre a cadeia de produção, geração e descarte destes materiais têm-se impactos que agridem de maneira direta o meio do qual fazemos parte. Uma das questões colocadas é a da gestão e gerenciamento dos resíduos sólidos urbanos (RSU), além dos trabalhadores que sobrevivem da separação e venda dos materiais recicláveis. Deste modo, tendo em vista este descompasso imposto pelo capital, que precariza o homem, o objetivo do trabalho é analisar os municípios de Presidente Prudente, Ourinhos e Assis, no que diz respeito à gestão e gerenciamento dos resíduos sólidos urbanos, assim como a organização dos catadores em cooperativas ou associações, levando em conta a valorização dos catadores, sendo eles, os responsáveis pela execução de todo o processo de coleta e venda dos resíduos sólidos recicláveis. Como procedimentos metodológicos, foram realizados trabalhos de campo nos municípios, entrevistas com os cooperados e análise junto às prefeituras sobre o modelo de gestão e gerenciamento dos resíduos.

In Brazil, rates of urban solid waste generation increase proportionally more than the annual growing of the population. The government, from its federal authority to the municipal spheres, faces increasing challenges for Urban and Environmental management regarding to solid waste in general and, in particular, municipal solid waste. Financial problems added to public health problems that worsen with the serious environmental impacts generated every year. In August 2010 Brazil the PNRS (National Policy on Solid Waste) was approved and sanctioned in which represented a true watershed in the country as a legal framework extremely ambitious and visionary. This work presents the successes and challenges that the municipality of Sorocaba/SP is facing after more than three years of PNRS sanctioned to conduct an Urban and Environmental management suited to the new legal bases towards the subject of solid waste. The results show a large gap between the content proposed by the law and the technical, financial and temporal reality to practical implementation by the municipal government. New legislation and federal incentives, consortiums among the cities, flexible deadlines and environmental education at all levels are certainly some proposals to catalyze processes that aim to solve and overcome the challenges of solid waste

O aumento da população, o crescimento das grandes cidades, da industrialização e do consumo, tem trazido preocupação com relação a sustentabilidade quanto à disponibilidade energética e quanto à destinação dos resíduos sólidos urbanos gerados. Dessa forma, é fundamental realizarem-se os estudos visando novas formas de reutilização dos resíduos gerados pelas atividades industriais. Os resíduos sólidos urbanos e os pneus inservíveis gerados trazem conseqüências ao meio ambiente e às populações quando destinados inadequadamente. A destinação final dos resíduos sólidos urbanos é complexa, sendo sempre um grande desafio para as administrações públicas. Com a Política Nacional de Resíduos Sólidos (instituída pela Lei n 12.305/2010), tem-se um marco da preservação ambiental, coma a gestão e gerenciamento de resíduos sólidos, com a ordem de prioridade: não geração, redução, reutilização, reciclagem, tratamento dos resíduos sólidos e disposição final ambientalmente adequada dos rejeitos e prevê, de forma inteligente, a atribuição aos fabricantes de responsabilidade pelo retorno de produtos descartados pelos consumidores. Uma alternativa para minimizar estes aspectos e impactos ambientais é o tratamento térmico com aproveitamento energético. Este processo contribui para mais uma solução de destinação dos resíduos, proporcionado uma redução das áreas a serem utilizadas nos aterros sanitários e contribuindo como uma fonte de geração de energia elétrica
