Municipal government policies supporting recycling cooperatives at the start of the 1990s and in the first years of the current century have contributed to resemanticizing trash rather than improving the living conditions of the street scavengers in the city of Rio de Janeiro. This idea was based on multiple case studies conducted in three post-consumption recycling cooperatives which have resulted from such policies. Interviews were held with three municipal government managers and 66 scavengers between 2002 and 2004, during a period of field observation that varied from two to six months in each case. Following a Foucaultian analysis approach, in this thesis post-consumption trash is considered as a discursive production. For this reason, the discourses have been analyzed (through an archaeology and a genealogy) that animated this object as a target condition of public policies. Thus, problematization of the trash has been proposed ¿ characterized by the concomitance of discourses related to an environmental and economic issue surrounding it, which would have impacted the scavengers' work. This proposal made it possible to consider the conditions that enable the scavengers to participate in this discursive production concerning trash. Problematization means the social enhancement of trash (its resemantization as recyclable) and the government policies were an attempt to make the scavengers adapt to this conjuncture. The conditions have been investigated that enable the scavengers to participate in the construction process of the discourse concerning trash (preparation of the strategies), in consonance with public policies. According to the three organizations observed, the public managers assumed that it would be possible for the scavengers to participate in the rules of discourse on trash, when they achieved economy of scale and when they sold to middlemen. Through the findings of the studies, however, it has been concluded that the ways in which these three organizations were managed enabled the scavengers to accede to the rules of discourse regarding problematized trash only when they could control the strategies that allow them to attend what is set by such rules.

Num quadro de escassez de recursos e de redefinição do papel do Estado, os municípios ganharam papel importante como provedores de novos serviços e de desenvolvimento econômico regional. A dinâmica de novos arranjos institucionais, com a participação de todos os atores políticos que compõem o poder local possibilita a busca de soluções de graves problemas da localidade, otimizando recursos e apresentando resultados mais eficientes. Ampliando a lógica da localidade para a união de municípios com mesma identidade social, cultural e econômica, a experiência dos Novos Arranjos Institucionais - Consórcio Intermunicipal do Grande ABC e a Câmara Regional do Grande ABC-- funcionando como espaços públicos para a busca de soluções de problemas locais, dão mostras de que o poder local de forma descentralizada e democrática, pode propiciar ações planejadas e cooperadas visando o desenvolvimento regional.corno um todo. Dessa maneira, os sete municípios do Grande ABC se unem para buscar soluções de problemas comuns, dentre eles a destinação final dos Resíduos Sólidos Urbanos, que é hoje um dos principais problemas urbanos a ser enfrentado. É neste. contexto, de disputa entre os atores políticos na Juta por seus interesses, que será demonstrada a possibilidade de .se alcançar uma relação entre Estado e Sociedade, em que o interesse público sempre prevaleça

Este estudo faz uma análise dos ambientes institucional, organizacional, tecnológico e competitivo que cercam o aproveitamento energético dos resíduos sólidos urbanos no Brasil, objeto de política recente lançada no país, que trata a questão superficialmente, priorizando, sobretudo, a destinação dos resíduos aos aterros sanitários, inclusive aqueles de origem orgânica. As análises realizadas mostram que, acima de uma gestão excelente do processo, as políticas de governo sobre o tema da recuperação energética de resíduos são fundamentais para a viabilidade destes empreendimentos, que é dependente também de um fortalecimento no ambiente organizacional, responsável pelas pressões políticas e centralização dos interesses sobre o tema. Uma análise do ambiente tecnológico concluiu que a recuperação energética de resíduos é dominada por empresas no Brasil e que pode ser ampliada em escala e tecnologias disponíveis, desde que o mercado de resíduos sólidos urbanos ofereça segurança ao investidor, sobretudo acima de outras fontes de energia renováveis que se valem das mesmas legislações existentes sobre a comercialização de energia elétrica, porém com menores custos de implantação. Diferentemente de outras fontes de energia, sob o contexto político atual, os empreendimentos de aproveitamento energético de resíduos sólidos urbanos são viáveis economicamente em condições muito específicas no Brasil, especialmente aquelas ligadas à falta de espaço ou ao estabelecimento de parcerias público privadas em que pesem os interesses de ambos os parceiros, como também ponderados os ganhos para o município nos pilares ambiental, social e econômico.

Over one-third of global food production goes to waste while over 850million people are fighting chronic hunger. The United States is the world’s largest food waster. One third of America’s food with an economic value of US$161 billion is wasted and less than 7% is recycled. American food waste ends up in landfills creating powerful methane gas emissions. South Korea, on the other hand, has implemented the world’s strictest food waste laws, and today diverts 93% of wasted food away from landfills turning such waste into powerful economic opportunities. This Master Thesis investigates the reasons behind global food waste by comparing South Korea and the US. It explores what these two nations are doing to address their respective food waste problems, South Korea successfully, the US not. The paper looks at the two countries’ respective policies and national characteristics, which impact decision-making and recycling processes. The effort concludes that South Korea has embarked on a necessary paradigm shift turning food waste into powerful economic drivers leading to a sharp decline in food waste. In the US, food waste continues to be a major problem without a national strategy to remedy waste. Any effort in the US, while laudable, is sporadic and local, and hence the US misses out on possibly important economic growth opportunities.

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.

In 2010 Brazil produced about 60.8 million of municipal solid waste, an amount 6.8% higher than in 2009 and six times the rate of urban population growth recorded in the same period. According to a study by the Brazilian Association of Companies of Special Wasteand Public Cleansing (Abrelpe), the average waste generated per person in the same period the country was 378 Kilograms, an amount 5.3% higher to 2009 (359 Kg). The total reached 60.8 milion tons of waste, 6.5 million tons were collected and not end up inrivers, streams and vacant lots. Of this total production, 42.4% or 22.9 million Tons, did not receive proper destination and destiny had dumps and landfills. The data show that the country is in upward trend in waste generation, but did not advance the appropriate destination at the same pace. The waste thus throw open cause public helth problems, such as proliferation of disease vectors (flies, mosquitoes, cockroaches, rats, and others). Generation of odors and especially the pollution of soil, surface water and groundwater through slurry ( liquid black, smelly and high pollution potential produced by the decomposition of organic matter contained in waste), affecting the water. This Study shows the popper closure of the areas, wich long has been degrading our natural resources, not to cause damage to nature and therefore society

Dengue is currently considered one of the most relevant public health problems worldwide. Studies indicate the surroundings of the houses as the preferred sites for the proliferation of Aedes aegypti. The residential areas are privileged environments for human development and contribute to the formation of the individual s identity and for the establishment of affective, social and cultural bonds. The purpose of this study was to investigate possible links between psychological indicators of pro-environmentalism and conservation status of residential backyards. Data collection was performed in 147 homes and methodological strategy involved the use of interview, the Scale of Ecocentric and Anthropocentric Environmentalism, Scale of Consideration of Future Consequences and a tool for environmental evaluation. It was found that the participants expressed as environmental practices the garbage recycling, besides they had the knowledge of how the transmission of dengue occurs. These residents showed ecofriendly motivated commitment: pro-environmentalist ecocentric and anthropocentric. In evaluating the backyard it was verified that the conservation conditions, in almost half of the homes, appeared as carelessness on the part of residents and those conditions are conducive to the proliferation of Aedes aegypti. The pro-environmentalists and guidance for the future identified by the scales were not associated with the conservation status of the backyards. However, it was found that the trends of reduction and stability of infestation levels are associated with self-reported environmental care. These results can contribute to the discussion and design of new mosquito control actions and practices of education and health information among the population

The research approaches recycling of urban waste compost (UWC) as an alternative fertilizer for sugarcane crop and as a social and environmental solution to the solids residuals growth in urban centers. A mathematical model was used in order to know the metal dynamics as decision support tool, aiming to establish of criteria and procedures for UWC's safe use, limited by the amount of heavy metal. A compartmental model was developed from experimental data in controlled conditions and partially checked with field data. This model described the heavy metal transference in the system soil-root-aerial portion of sugarcane plants and concluded that nickel was metal to be concern, since it takes approximately three years to be attenuated in the soil, reaching the aerial portions of the plant at high concentrations. Regarding factors such as clay content, oxide level and soil pH, it was observed that for soil with higher buffering capacity, the transfer of the majority of the metals was slower. This model may become an important tool for the attainment of laws regarding the UWC use, aiming to reduce environment contamination the waste accumulation and production costs.

O estudo de caso analisa o fen??meno de judicializa????o de pol??ticas p??blicas, o qual se d?? quando se transfere quest??es de cunho pol??tico, t??picas do Poder Executivo e do Legislativo, para serem analisadas pelo Poder Judici??rio. Considerando-se o extenso leque de direitos sociais, o Poder Judici??rio passa a ser tamb??m demandado em quest??es pol??ticas mais espec??ficas, previstas ou n??o em pol??ticas p??blicas, o que gera in??meras possibilidades de atua????o para esta esfera de poder. O presente caso analisa, portanto, a tens??o na defini????o de compet??ncias entre os Poderes Judici??rio e Executivo, no que se refere ?? coleta de lixo no munic??pio de Cambuquira, Minas Gerais. Ele aborda dois direitos sociais: o direito ?? sa??de e ao meio ambiente saud??vel. O estudo suscita, portanto, o debate sobre a exist??ncia de uma pol??tica p??blica, que passa a ser questionada no Poder Judici??rio, debatendo-se quais seriam os reais limites da democracia
