Since the beginning of it’s existence the humankind coexists with the production of waste, both organics and inorganics. Over the years the world population is raising, and consequently the different kinds of waste, causing significant problems not only for the public authorities, but also for the population, not only those related with its final or temporary destination but also with its crescent production. Considering it, the cities are not able to handle there volumes, and its landfills and dumps are working over their capacities, leading to a serie of environmental problems due to the lost of environmental quality and the natural and social vulnerabilities arising. This paper plans to working over visits, photographic registration and a review on the theme literature, study the perception and valuation of the landscape on the Ribeirão Preto landfill, São Paulo state (SP), that today is disabled but still an area of risk and environmental vulnerability, well as the perception of environmental quality in the surrounding population

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 management of solid waste has been a great challenge to public managers both because of its high operational costs and increasing waste generation. Besides environmental and public health harm, it involves high costs to be mitigated. It is necessary to seek solutions that focus on, amongst other matters, economic efficiency for a healthy environment. This could be reached with sustainable development, which has proven itself as an alternative model of development to the actual one in place. In order to ensure that sustentability is the goal of an activity, it is necessary to establish goals and to evaluate a system in order to track opportunities and correct possible mistakes, that is, it is necessary to elaborate a Waste Management Plan. However, in order to establish goals, it is also necessary a good description of the management of solid waste, thus diagnosis is a core aspect in the building of an specific law, as it will allow for the knowledge of the actual status of solid waste collection in Osasco town, showing what progress has been made in recent years, identifying current problems and generating the foundations to build future perspectives in the area. The present work has seeked to elaborate a diagnosis on waste management in Osasco municipality, presenting places for consultation and analysing how it meets the current legislation in place, enabling it to serve as a model for the elaboration of other diagnosis in other Brazilian municipalities

The destination of urban solid waste has became a very relevant theme because of the fast growth of cities. Bauru, a strategically located municipality, needs solutions for that problem. This research aims to show solid waste management in Bauru through a survey of the selective or regular garbage collection programs, treatment and final disposal of the waste. To do so, a questionnaire with 85 questions was used about solid waste management in the municipality and visits were made to the solid waste collection and disposal sites. Bauru has a bad selective collection program and very significant clandestine disposal of Hazardous waste. Furthermore, it doesnot treat hospital waste and has a deficient final disposal landfill.

A gestão de resíduos em distribuidoras de eletricidade é bastante complexa, pois enquadram-se em vários tipos (valorizados ou não) e gerados em grande quantidade. Em 2009, a AES Eletropaulo gerou quase quatro mil toneladas de resíduos não perigosos, subdivididos em 30 tipos. Uma divisão por materiais, após desmontagem e separação dos diferentes materiais contidos nos fios, cabos, chaves, isoladores com ferragem e para-raios, subiria o valor da venda em R$ 600 mil. Isso geraria cerca de 214 toneladas de porcelana que, moídas, poderiam substituir as 210 toneladas de brita compradas anualmente pela concessionária para uso em subestações. Cerca de 160 toneladas de porcelanas intactas poderiam ser utilizadas na confecção de gabiões para contenção de encostas. Além disso, peças de ferro galvanizado poderiam ser decapadas e novamente galvanizadas para reaproveitamento.

The issue of environmental impacts to human health and the generation and disposal of solid waste has led to a change of paradigms for your face, highlighting the need for sustainable management of municipal solid waste (MSW). In this context, the expansion of landfills in Brazil in recent decades makes it necessary to sustainable management of waste generated by this type of enterprise, since its implementation. The aim of this study was to perform a diagnosis of the generation of waste in a landfill, in the expansion phase, and the alternatives adopted for its management. The qualitative diagnosis was made from observations on site and the wastes were classified and quantified from August 2011 to January 2012. In the diagnosis was considered the reduction, reuse and recycle, in that order. The results of this study showed that the residue of the greatest generation was PEAD geomembranes used in the waterproofing of the landfill, reaching 7 t, followed by PVC pipes, which reached 850 kg, both destined for recycling. The largest volume of wastewater generated corresponded to the leachate, reaching 11,500 m3 , which were sent for treatment

Criado inicialmente com a função básica de proteção aos pés, o calçado tornou-se um objeto de desejo e um acessório essencial de moda. Entre 1950 a 2015, estima-se que a produção mundial passe de 2,5 bilhões de pares produzidos para 25 bilhões de pares por ano, crescimento bem maior do que a população mundial. O couro, principal matéria-prima para a confecção de calçados, caracteriza-se por gerar grandes quantidades de resíduos ao longo de toda a cadeia produtiva. Especificamente na indústria coureiro-calçadista, o problema concentra-se nos elevados volumes de resíduos gerados na atividade produtiva, podendo causar desperdícios e grandes volumes de resíduos a serem descartados, envolvendo, principalmente, questões financeiras e ambientais. Países como Alemanha e Estados Unidos possuem legislação específica sobre a gestão de resíduos desde os anos 1970. No Brasil, depois de mais de 20 anos de tramitação no Congresso Nacional, em 2010, foi instituída a Política Nacional de Resíduos Sólidos, que reúne princípios, objetivos, instrumentos, diretrizes e metas, que deverão ser adotados pelos governos nas esferas federal, estadual e municipal, bem como pelas empresas com vistas à gestão integrada e ao gerenciamento ambientalmente adequado dos resíduos sólidos. Dessa forma, o objetivo desta tese foi desenvolver um modelo de gestão de resíduos industriais para o setor calçadista de Franca-SP com vistas à Política Nacional de Resíduos Sólidos. O desenvolvimento do modelo teve como ponto de partida um estudo bibliográfico sobre o assunto e, na sequência, por intermédio de uma pesquisa aplicada, conseguiu-se, em um primeiro momento, analisar a situação atual para compreender o modelo de gestão de resíduos vigente e realizar uma pesquisa de diagnóstico dos resíduos industriais do setor. Tal pesquisa possibilitou verificar que atualmente, esses resíduos, são enviados em sua totalidade para aterros sanitários, possibilitou também sua quantificação e cálculos dos custos envolvidos para transporte e destinação. Na sequência, realizaram-se estudos sobre a viabilidade técnica e financeira para tratamento térmico desses resíduos e a busca de benchmark no setor. O estudo também proporcionou uma contribuição de caráter mais prático e/ou gerencial ao recomendar diretrizes para a elaboração de um plano de gestão integrada de resíduos industriais para o setor, e uma proposta de gestão compartilhada dos resíduos industriais entre a entidade de classe e as indústrias calçadistas, com vistas à eliminação de envio desses resíduos para aterros. Dessa forma, contribuiu também para a elaboração do Plano Municipal de Gestão Integrada de Resíduos Sólidos do município em questão. Nesse sentido, após as análises e desdobramentos das etapas anteriores, foi possível propor um modelo de gestão de resíduos industriais, bem como demonstrar sua viabilidade técnica e financeira. Tal modelo foi denominado \"Modelo de Equiparação de Custos com Eficiência Ambiental\".
