Condições mínimas para o encerramento de áreas que abrigaram resíduos sólidos domiciliares

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

Diagnóstico dos resíduos de construção e demolição para elaboração e implantação da gestão integrada dos RCD no município de Guanambi – BA

Taking as starting the environmental, social and economic impact of construction and demolition waste in Brazilian cities were created legal mechanisms for management and administration, seeking to minimize the impacts to the maximum, since the irregular deposition can be characterized as environmental crime. CONAMA Resolution No. 307 of 2002 establishing the mandatory implementation of an Integrated Management System Construction Waste and Demolition, guiding the classification and designation of the waste generating agents, collection agents and transporters, and the areas of culling and disposal of waste. The technical partnership between the Ministry of Cities, the Environment Ministry and the Caixa Econômica Federal, coordinated by Pinto & Gonzales (2005) Management in the work and management of construction waste, proposed a guidance manual to guide the implementation of a System Integrated Management of Construction Waste in Municipalities. The municipality of Guanambi in the state of Bahia, in full economic rise, lacks a waste management of construction and demolition, since there has areas for the disposal of waste being proposed in this paper the diagnosis of waste generation in the municipality as part of the methodology proposed by the work of Pinto & Gonzales (2005).

Potencial de aproveitamento de agregados reciclados de resíduos da construção e demolição

CONAMA Resolution 307 / 02, in Article 4, states that the primary goal of those involved in the reuse process of construction and demolition waste is not the generation of such wastes, secondarily is the reduce, reuse, recycling and proper disposal of such material. The disposal problem of large volumes of waste generated coupled with the scarcity of natural resources and environmental degradation involved in the extraction process of such materials resulted in several studies, that after many analyzes proposed various forms of reuse and recycling . The NBR 15.116/04 provides requirements for the use of recycled aggregates in paving and concrete without structural function. This work aims to show the usage potential of recycled aggregates from waste generated in construction and demolition sampled Group AB Areias, Pindamonhangaba (SP) in order to meet the standards in Brazil, as well as the environmental contribution by reducing the use of raw materials extracted from nature. After stabilization and particle size analysis of the California Bearing Ratio and Proctor, obtained mixtures of recycled aggregates showed higher values submitted by the minimum standards related, with excellent potential for use in paving

Diagnóstico dos resíduos gerados nas oficinas mecânicas de veículos automotivos do município de São Carlos-SP

The mechanical garages do varied types to activities related to the reparation from vehicles such as change from Motor oil, change and cleaning from car pieces, motor rectification, among others. These activities generate different kinds of waste and wastewater that when disposed in an inappropriate way can pollute the environmentand cause risks to the public health. Despite the environmental issues that involves these enterprises, they aren´t object of environmental licensing and there are any rules that regularizes their activities with the goal of these possible environmental impacts mitigation. The environmental diagnosis proposed by the present work has as goal the knowledge of the possible environmental aspects and their effects in the environment, for establishing control measures and from that to generate subsidy for environmental normatization of the sector in the municipal level. Furthermore, it should also define practices as waste production reduction, separation of them at the generator source and convenient final disposal, as well as wastewater production reduction and treatment of them before its launching in the wastewater network. The environmental diagnosis was based on a survey realized in garages from the city of São Carlos – SP, in order to define the more important characteristics of this activity that are related to the environment and public health. From the obtained information from the survey and the interpretation of the data, subsidy for the municipal environment management of the mechanical garages were generated.

The implementation of residue selective collection has brought to the city of Sao Manuel an incalculable benefit. It brought a better life for a group of adults and children that lives in a humanitarian condition of extreme poverty. These people live in an open-air dump, disputing the remains found in fifteen tons of garbage that are deposited at the site almost every day.The objective of this paper is to present thecollectors annual income profile and the volume of solid waste collected.To present these factors, the total and fractionated amount according to their material items, collected since the creation of the Association in February 2003 until December 2008, were considered., In addition,the social gains were enumerated. These factors were developed from a theoretical base for municipal solid waste involving environmental, social, and financial concepts. Based on these results it was found that the ACAPEL income value was above the average of other income indicators of the population analyzed, besides the social value enhance that the creation of the Association brought to the people who work there.

Gerenciamento de resíduos da construção civil: análise e atualização dos estudos realizados na UNESP-FEG para o município de Guaratinguetá

The construction industry is a large consumer of natural resources and one of the largest generators of residues with significant impacts on the environment. Because of the large production of Construction Industry Residues (RCC), it is essential reliable and updated information about generation, composition and classification sources of these residues, especially for management, recycling and final disposal. RCC represent the most part of solid residues generated in a city. In this way, the management of these residues is an issue that is gaining increasing importance in the Brazilian scenario, since the legal and society requirements to internalize the sustainability in the construction process - since the extraction, use, wastage savings, reutilization until the appropriate discard has been increasing in the last years. The present work objective is updating the quantities produced and collected in Guaratinguetá-SP, based on data collected with the municipal administrative entities that act direct or indirectly in the RCC management, elaborate a detailed bibliographic review, with special attention to the graduate works that were realized in FEG about this theme. With this material, scenarios to a better adequacy of the administrative structure to managements RCC activities, as well as was suggested actions to achieve these scenarios

Avaliação das condições ambientais e de trabalho em salas cirúrgicas e de necropsia - estudos de casos em hospitais públicos e IMLs da região metropolitana do Rio de Janeiro

A qualidade do ar é um importante indicador de saúde ambiental, sendo o seu monitoramento contínuo necessário. Apesar da relevância do tema, há muitos países em que os limites de exposição para agentes biológicos ainda não foram estabelecidos ou foram definidos de forma inadequada, podendo comprometer a qualidade ambiental. Os ambientes hospitalares, assim como as salas de necropsia podem apresentar problemas de contaminação do ar por agentes microbiológicos, necessitando de monitoramento contínuo a fim de evitar a ocorrência de doenças nos trabalhadores e na população em geral. Este estudo realizou a avaliação microbiológica do ar em hospitais públicos e IMLs da região metropolitana do Rio de Janeiro em salas cirúrgicas e de necropsia. A pesquisa exploratória e descritiva baseou-se em levantamento bibliográfico e investigação de campo, através de estudos de casos. Os dados foram obtidos por meio de entrevistas e observação direta nos locais de trabalho, onde foram realizadas as avaliações microbiológicas do ar. As variações em salas cirúrgicas para bactérias e fungos foram respectivamente de 14,99 ufc/m3 88,29 ufc/m3 e de 45,93 ufc/m3 - 742,09 ufc/m3. Já nas salas de necropsia os valores para bactérias e fungos variaram respectivamente de 18,96 ufc/m3 54,9 ufc/m3 e de 144,87 ufc/m3 - 1152,01 ufc/m3. Foram identificados tanto no ambiente cirúrgico como nas salas de necropsia a presença dos seguintes fungos: Aspergillus sp., Neurospora sp., Penicillium sp., Fusarium sp., Cladosporium sp., Curvularia sp., e Trichoderma sp. Já em relação às bactérias foram identificadas as presenças de Staphilococcus sp., Streptococcus sp. e Micrococcus sp. Foram traçadas recomendações para melhoria da qualidade ambiental e do ar. Os resultados indicaram que os valores são elevados quando comparados com as recomendações das normas internacionais. Foram encontrados valores inferiores aos sugeridos pela CP n. 109 da ANVISA. A presença de microrganismos patogênicos sugere adoção de medidas de controle ambiental. O estudo apontou a necessidade urgente do estabelecimento de valores de referência para ambientes hospitalares no Brasil a fim de garantir condições seguras que não venham a comprometer a saúde dos pacientes e profissionais de saúde envolvidos.

Valorization of solid wastes from cellulose and paper industry

This thesis reports in detail studies of industrial solid wastes valorization as alternative raw materials. All tested wastes are classified as non-hazardous and are generated in the pulp and paper process, including primary sludge, dregs, grits, lime mud and bottom ash (this generated in a process that occurs in parallel to the production of cellulose, whose aim is the production of energy to supply the plant through the combustion of forest biomass in fluidized bed). A detailed general characterization was performed at each waste and according to their characteristics, they were selected some applications in materials with potential use, specifically in Fibercement, Bituminous Mixture for regularization layer and industrial mortars (rendering mortars and cementitious-adhesive). After decided to application each waste was specifically tested to proceed the setting up of formulations containing different content of waste in replacement of the raw conventional material. As an isolated case, the bottom ash was tested not only as an alternative raw material for construction materials, but also it was tested for its use in fluidized bed in which the waste is generated as raw material. Both dregs and bottom ash had undergone special treatment to make possible to obtain a better quality of waste in order do not compromise the final product characteristics and process. The dregs were tested in bituminous mixtures as received and also washed (on the laboratory scale to remove soluble salts) and bottom ash were washed and screened in industrial scale (for removal of soluble salts, especially chlorides and coarse fraction particles elimination - particles larger than 1 mm size). The remaining residues form used in such as received avoiding additional costs. The results indicated potential and some limitations for each application to the use of these wastes as alternative raw material, but in some cases, the benefits in relation to valorization overlap with its limitations in both aspects, environmental and economic.

A situação do Ecodesign em empresas moveleiras da região de Bento Gonçalves, RS : análise da postura e das práticas ambientais

A crescente preocupação com a melhor qualidade do meio ambiente, seja por força da legislação ou pela conscientização da população, faz com que surjam novas técnicas que auxiliam as empresas a participarem ativamente da construção de um modelo de produção ambientalmente sustentável e economicamente viável. Dentre estas novas técnicas, destaca-se a aplicação dos conceitos do Ecodesign, que propõem a integração dos aspectos ambientais no projeto de novos produtos, que é o tema deste trabalho. A questão de pesquisa, refere-se a como as empresas do setor moveleiro tratam as questões ambientais, sob a ótica do Ecodesign. A partir desta questão, foi determinado o objetivo geral de identificar práticas e posturas associadas ao Ecodesign, nas empresas moveleiras filiadas ao Sindicado das Indústrias Moveleiras de Bento Gonçalves, no RS. Os objetivos específicos visaram verificar a postura ambiental das empresas pesquisadas, identificar as atuais práticas relacionadas ao Ecodesign e identificar as principais dificuldades de implantação dos conceitos, apontadas pelos gestores das empresas pesquisadas. Como base teórica, foi realizado um estudo do Ecodesign, comparando diferentes visões e uma revisão do atual panorama do setor moveleiro, em nível nacional e mundial. O método escolhido foi o estudo descritivo, com a utilização de um questionário composto por questões voltadas a atingir os objetivos propostos, aplicado em 27 empresas do setor moveleiro. Como conclusão deste estudo, verificou-se que as empresas pesquisadas possuem uma postura de receptividade média frente às questões ambientais, embora não atuem de forma pró-ativa, pois esperam a concretização de tendências para agirem. Há um grande potencial para implantação de técnicas que causem menor impacto ao meio ambiente, pois já são utilizadas algumas que podem ser relacionadas ao Ecodesign, mas ainda não são exploradas plenamente pelas empresas.
