Thus, Federal Law 12,305 / 2010, which established guidelines and showed ways for a responsible management of urban solid waste, was introduced. Linked to this, there is also a quest to make renewable energies and alternative sources of fuel viable, such as biogas generated through municipal solid waste. There is a promising market for new waste treatment technologies, as well as an increase in the search for greater knowledge of this new market that starts in the country, by public and private managers, in order to consolidate and nationalize techniques developed in other continents. In this work, the possibility of electric power generation using the biogas generated by solid urban waste in the city of Jundia?-SP and an economic analysis of the whole system will be discussed. The methodology to be used is the agreement between the City of Jundia? and the German government, with the author's adaptations, taking into account the standard DIN 38414-8 (1985-06). The results show a good potential for the generation of biogas, showing a revenue of one hundred sixty-eight million, two hundred and ninety-five thousand, two hundred and ninety-five reais and seventy-six cents (R $ 168,295,295.76) per year for the city of Jundia?. / Com o aumento da popula??o das cidades brasileiras e o despejo irregular dos res?duos s?lidos urbanos, houve a necessidade da cria??o de diretrizes para a implanta??o de uma gest?o de res?duos s?lidos nos munic?pios. Assim, surgiu a Lei Federal 12.305/2010, que estabeleceu diretriz e mostrou caminhos para uma gest?o respons?vel dos res?duos s?lidos urbanos. Atrelado a isso, h? tamb?m uma busca por tornar vi?veis energias renov?veis e fontes alternativas de combust?veis, como, por exemplo, o biog?s gerado atrav?s dos res?duos s?lidos urbanos. Vislumbra-se um mercado promissor para novas tecnologias de tratamento de res?duos, bem como um aumento na busca por maior conhecimento desse novo mercado que se inicia no pa?s, por parte dos gestores p?blicos e privados, a fim de consolidar e nacionalizar t?cnicas desenvolvidas em outros continentes. Neste trabalho, ser? abordada a possibilidade de gera??o de energia el?trica utilizando o biog?s gerado pelos res?duos s?lidos urbanos da cidade de Jundia?-SP e uma an?lise econ?mica de todo o sistema. A metodologia a ser empregada consta do conv?nio firmado entre a Prefeitura de Jundia? e o governo Alem?o, com adapta??es do autor, levando em conta a norma DIN 38414-8 (1985-06). Os resultados obtidos permitem vislumbrar um bom potencial para a gera??o de biog?s, mostrando uma renda de R$168.295.295,76 (cento e sessenta e oito milh?es, duzentos e noventa e cinco mil, duzentos e noventa e cinco reais e setenta e seis centavos) por ano para a cidade de Jundia?.

In the Brazilian case, and with regard to territorial public policies, such as urban planning and urban and regional planning,discussions generally restricted to the field of administrative law, predominantly instrumental in character, whose effects invariably limited to specific actions, topical and devoid of virtue to reach the root causes of urban issue. And more. They reappear with the contemporary environmental crisis. Another factor that affects decisively reflection and proposition urban instruments developed with a view to solving the urban problems is the application of the concept applied to management of public affairs. Originally conceived in the context of organizations, employment management, to migrate to public administration, reduces the understanding of the political dimension to the city's plan merely negotiated territorial management. This also proves insufficient, which will be addressed through a particularly significant that relates environmental and urban issues: the National Policy on Solid Waste. / Visando contribuir nos debates que envolvem o equacionamento da problem?tica urbanoambiental, a disserta??o parte do pressuposto de que certas abordagens, por se bastarem ?s an?lises conjunturais, s?o impotentes para lidar com a natureza estrutural que as revestem. No caso brasileiro, e no que diz respeito ?s pol?ticas p?blicas territoriais, como o urbanismo e o planejamento urbano e regional, as discuss?es geralmente restringem-se ao campo do direito administrativo, de car?ter predominantemente instrumental, cujos efeitos invariavelmente limitam-se ?s a??es pontuais, t?picas e desprovidas da virtude de atingir as causas origin?rias da quest?o urbana. E mais. Elas recrudescem com a crise ambiental contempor?nea. Outro fator que compromete, decisivamente, a reflex?o e a proposi??o de instrumentos urban?sticos desenvolvidos, com vistas ao equacionamento da problem?tica urbana, ? a aplica??o da no??o de gest?o aplicada ? coisa p?blica. Originariamente concebida no contexto das organiza??es, o emprego da gest?o, ao migrar para a administra??o p?blica, reduz o entendimento da dimens?o pol?tica da cidade ao plano meramente negociado de gest?o territorial. Isso tamb?m se mostra insuficiente, o que ser? abordado por meio de um caso particularmente significativo que relaciona quest?es urbanas e ambientais: a Pol?tica Nacional de Res?duos S?lidos.

The move towards sustainability calls for the generation / evaluation systems in their direction, through the incorporation of environmental requirements and in line with the National Policy on Solid Waste. Therefore, the proposed research supports the importance of social and environmental vision, complementing the technical view, the system for management of solid waste from East London, which is a municipality that has a system whose inadequacies are configured in environmental risk and health. Therefore, by observing, applying the model of sustainability indicators and content analysis of interviews, this research proposes to investigate the principles of sustainability and social participation are presented and what is the perception of risk about the inadequacies in the system. The results confirmed the hypotheses of the study and draw a picture of worrying data, such as very unfavorable indicators of sustainability, lack of channels of participation, uncommitted investments with the management system, devaluation of the collector of waste and differing perceptions about the risk by making actors act in isolation. This worrying situation is eased by the appearance of a series of elements are configured as opportunities for the integration of environmental principles in the system. And despite the inability of managers to participate in the research system, yet it behaves as an opportunity to implement public policies in the area of solid waste such as: the preparation of the municipal waste, the institutionalization of selective collection and organization of cooperative with the support of companies present in the city and educational institutions as the Federal Institute. The research is an opportunity for the implementation of policies in the area of solid waste and will collaborate with the building instruments for the quality of life of residents, for the socioeconomic conditions of collectors and the move towards a sustainable society / A realidade ambiental global aponta o desenvolvimento sustent?vel como ?nica op??o vi?vel para o enfrentamento da crise que se apresenta. O caminhar para a sustentabilidade requer a constitui??o/avalia??o de sistemas em sua dire??o, por meio da incorpora??o de preceitos ambientais e em conson?ncia com a Pol?tica Nacional de res?duos S?lidos. Por isso, a pesquisa proposta defende a import?ncia da vis?o socioambiental, complementando o olhar t?cnico, para o sistema de gest?o de res?duos s?lidos de Jo?o C?mara, que consiste num munic?pio que apresenta um sistema cujas inadequa??es se configuram em risco ambiental e a sa?de. Portanto, por meio da observa??o, aplica??o do modelo de indicadores de sustentabilidade e an?lise de conte?do de entrevistas, esta pesquisa prop?s averiguar como os princ?pios da participa??o social e da sustentabilidade se apresentam e qual ? a percep??o de risco sobre as inadequa??es neste sistema. Os resultados confirmaram as hip?teses da pesquisa e desenham um quadro de preocupantes dados, tais como: indicadores muito desfavor?veis a sustentabilidade, inexist?ncia de canais de participa??o; descomprometimento da gest?o com investimentos no sistema; desvaloriza??o do catador de res?duos e percep??es divergentes sobre o risco fazendo os atores agirem de formas isoladas. Esse quadro preocupante ? amenizado pelo aparecimento de uma s?rie de elementos que se configuram como oportunidades para a inser??o dos princ?pios ambientais no sistema. E apesar da impossibilidade de participa??o dos gestores do sistema na pesquisa, ainda assim, ela se porta como oportunidade ? implementa??o de pol?ticas p?blicas na ?rea de res?duos s?lidos tais como: a elabora??o do plano municipal de res?duos, a institucionaliza??o da coleta seletiva e a organiza??o de cooperativa com o apoio das empresas presentes no munic?pio e das institui??es de ensino como o Instituto Federal. A pesquisa ? uma oportunidade para a implementa??o de pol?ticas na ?rea de res?duos s?lidos e colaborar? com a constru??o de instrumentos para a qualidade de vida dos moradores, para a inser??o socioecon?mica dos catadores e para o caminhar rumo a uma sociedade sustent?vel

The soil-cement bricks are one of the alternatives to masonry construction. These elements, after a short curing period, provide compressive strength similar to that of solid bricks and ceramic blocks, and the higher the resistance the higher the amount of cement used. We used the soil from the city of S?o Jos? do Mipibu / RN, the banks of the River Baldun, cement CPIIZ-32 and residue of drill cuttings from oil wells drilling onshore wells in the town of Mossley, RN, provided Petrobras. To determine the optimum mix, we studied the inclusion of different residues (100%, 80%, 70%, 60% and 50%) where 15 bodies were made of the test piece. The assessment was made of bricks made from simple compression tests, mass loss by immersion and water absorption. The experimental results proved the efficiency and high utilization of the waste from the drilling of oil wells, making the brick-cement-soil residue with a higher strength and lower water absorption. The best result in terms of mechanical strength and water absorption for the ternary mixture was 10% soil, 14% cement and 80% residue. In terms of binary mixtures, we obtained the best result for the mix-cement residue, which was 14% cement incorporated in the residue / O presente trabalho consiste no estudo das caracter?sticas e propriedades tecnol?gicas de tijolos solo-cimento formulados a partir de misturas bin?rias e tern?rias de cimento Portland, areia, ?gua, com e sem adi??o de cascalho proveniente da perfura??o de po?os de petr?leo, que poder?o ser utilizados pela ind?stria, com o objetivo de melhorar seu desempenho e diminuir seu custo utilizando o res?duo e, conseq?entemente, aumentando sua vida ?til. Os tijolos de solo-cimento constituem uma das alternativas para a constru??o em alvenaria. Esses elementos, ap?s pequeno per?odo de cura, garantem resist?ncia ? compress?o simples similar ? dos tijolos maci?os e blocos cer?micos, sendo a resist?ncia tanto mais elevada quanto maior for ? quantidade de cimento empregada. Foi utilizado o solo proveniente do Munic?pio de S?o Jos? do Mipib?/RN, as margens do Rio Baldun, cimento CPIIZ-32 e res?duo de cascalho de perfura??o de po?os de petr?leo proveniente da perfura??o de po?os Onshore, no munic?pio de Mossor?/RN, fornecido pela Petrobras. Para a determina??o da mistura ?tima, estudou-se a inclus?o de teores de res?duos diferenciados (100%; 80%; 70%; 60% e 50%) onde foram confeccionados 15 corpos-de-prova. A avalia??o dos tijolos confeccionados foi feita a partir de ensaios de compress?o simples, perda de massa por imers?o e absor??o de ?gua. Os resultados experimentais comprovaram a efici?ncia e o elevado potencial de utiliza??o do res?duo proveniente da perfura??o de po?os de petr?leo, tornando o tijolo de solo-cimento-res?duo com uma maior resist?ncia mec?nica e menor absor??o de ?gua. O melhor resultado, em termos de resist?ncia mec?nica e absor??o d ?gua, para a mistura tern?ria, foi de 10% de solo, 14% de cimento e 80% de res?duo. Em termos de misturas bin?rias, obteve-se o melhor resultado para a combina??o cimento-res?duo, que foi de 14% de cimento incorporado no res?duo

Another negative factor is the disposal of waste gypsum in inappropriate places, thus contributing to the degradation of environmental quality, due to the leaching of this waste and may trigger the formation of sulfuric acid. Therefore, based on this picture, processing and reuse of waste coating, combined with the ceramics industry, which is a strong potential in the reuse of certain types of waste, promote mutual benefits. Thus the overall objective of this work is to conduct a search with scientific and technological aspects, to determine the effect of the incorporation of the residue of plaster for coating, from the building, the formulation of bodies for red ceramic. The residue of plaster coating was collected and characterized. They were also selected raw materials of two ceramic poles of the state of Rio Grande do Norte and formulations have been made with the intention of obtaining those with the best physical and mechanical properties, the residue was added the percentage of 5%, 10%, 15%, 20%, 25% and 30%, in the best formulation of ceramic industry 1 and, according the properties analyses, 5%, 10% and 15% as the best results of ceramic industry 2. The samples were sintered at temperatures of 850 ?C, 950 ?C and 1050 ?C, the heating rate of 5 ?C / min with isotherm of two hours. They were submitted to testing technology, such as lineal shrinkage, water absorption, apparent porosity, apparent density and bending resistence. The residue incorporation best results in the formulations of mass in red ceramic, were observed between the temperatures of 850 ?C and 950 ?C, in those formulations that have illite clays and medium plastic in their composition, in the range of 0% to 15% residue incorporated / Na constru??o civil, durante o processo de execu??o de grandes ou at? mesmo pequenas obras, h? um desperd?cio consider?vel de gesso nas etapas de revestimento, tornando-se este um fator negativo, pois parte das perdas destes processos construtivos permanece incorporada nas constru??es, na forma de componentes, cujas dimens?es finais s?o superiores ?quelas projetadas. Outro fator negativo ? a disposi??o dos res?duos de gesso em locais inadequados, contribuindo assim para a degrada??o da qualidade ambiental, devido ao processo de lixivia??o deste res?duo, podendo desencadear na forma??o de ?cido sulf?rico. Baseado neste panorama, a transforma??o e o reaproveitamento dos res?duos de revestimento, aliada ? ind?stria da cer?mica, que ? um forte potencial no reaproveitamento de alguns tipos de res?duos, promoveria benef?cios m?tuos. O objetivo geral deste trabalho foi de realizar uma pesquisa com aspectos cient?ficos e tecnol?gicos, para verificar o efeito da incorpora??o do res?duo de gesso para revestimento, proveniente da constru??o civil, na formula??o de massas para cer?mica vermelha. As mat?rias-primas foram coletadas de dois p?los cer?micos do Estado do Rio Grande do Norte e formuladas com o intuito de obter aquelas com as melhores propriedades f?sicas e mec?nica, tendo sido incorporados os percentuais 5%, 10%, 15%, 20%, 25% e 30% de res?duo, na melhor formula??o da ind?stria cer?mica 1 e, de acordo com a an?lise dos seus resultados, de 5%, 10% e 15% na melhor formula??o da ind?stria cer?mica 2.

Nevertheless due to its rapid decomposition and release of odors, this practice hamper?s the operation and implementation of a recycling system. These facts encouraged our research to find an efficient system for the management of organic waste, not only for the use of official workers responsible for managing these wastes, but also for non-governmental institutions. The Recycling for Life Community Association ? ACREVI (Associa??o Comunit?ria Reciclando para a Vida), together with the municipal authorities of Mossor?-RN, Brazil, have assumed the social role of collecting and recycling solid waste produced by most of the local population. However, it was observed that the organic waste it collected was not receiving any treatment. This present work aims to make compost with mixed waste (green waste and organic household), and then do chemical analysis of the material in view to use the waste as organic fertilizer. The objective being: to share the knowledge acquired by putting it into a very simple language accessible to people with little education. The experiment was conducted at ACREVI, Mossor? (RN), and the compost was obtained following the method "windrow", forming three cells (I, II, III) with conical shape, dimensions of 1.6 meters and 2.0 meters in diameter for cells I and II, and 1.0 meters high and 2.0 meters in diameter for cell III. The process was accompanied by analysis: CHN elemental, a variation of cell temperature, humidity, pH, TKN, bulk density, nutrients and heavy metals. Stabilized organic compounds reached the C/N ratio of 10.4/1 cell I and 10.4/1 in the cell II in the cell, showing how good soil conditions, with potential to improve the physical properties of any soil and pH acid soils, has presented the cell III at the end of the process the C/N 26/1, is a high ratio may be associated with the stack size III, thus changing the optimal conditions for the occurrence of the process. The levels of heavy metals in the analyzed compounds were lower than those established by the SDA normative instruction, N? 27, of 5 June, 2006. The use of pruning trees and grass are used in small-scale composting, while generating a quality compost in the final process, it also created an important condition for a correct sizing of the composting piles. Under the studied conditions it is not advisable to use cells with a height of 1.00 m in height and 2.00 m in diameter, as these do not prevent the rapid dissipation of heat and thus can not be a good product at the end of composting. The composting process in the shed of the association and the preparation of the primer enabled the development of an alternative technology to generate income for members of ACREVI. / Durante d?cadas e ainda hoje no Brasil, assim como em muitos pa?ses do mundo a deposi??o de res?duos org?nicos biodegrad?veis em aterro foi uma pr?tica muito comum, pois a r?pida decomposi??o e a libera??o de odores destes res?duos dificultam a operacionaliza??o e aplica??o de um sistema de reciclagem. Estes fatos incentivam ? busca de medidas eficientes para a gest?o de res?duos org?nicos n?o s? nas entidades oficiais respons?veis pela gest?o destes res?duos, mas tamb?m nas institui??es n?o governamentais. A Associa??o Comunit?ria Reciclando para a Vida ACREVI, com o apoio da prefeitura municipal de Mossor?, Brasil, tem assumido o papel social da coleta e reciclagem de res?duos s?lidos produzido por grande parte da popula??o local. Por?m, observou-se que os res?duos org?nicos que ela coleta n?o est?o recebendo qualquer tratamento. Nesse trabalho objetivou-se realizar a compostagem com misturas de res?duos urbanos (res?duos verdes e org?nicos domiciliares), fazer a an?lise qu?mica desse material, tendo em vista sua utiliza??o como adubo org?nico, e repassar o conhecimento produzido em linguagem bem simples e acess?vel a pessoas com baixa escolaridade via produ??o de uma cartilha de compostagem. O experimento foi realizado na ACREVI, Mossor? (RN) e o produto da compostagem foi obtido seguindo o m?todo windrow , formando tr?s pilhas (I, II, III) com formato c?nico, dimens?es de 1,6 metros de altura e 2,0 metros de di?metro para as pilhas I e II, e 1,0 metro de altura e 2,0 metros de di?metro para a pilha III. O processo foi acompanhado atrav?s das an?lises: elementar de CHN, varia??o de temperatura da pilha, grau de umidade, pH, NTK, densidade aparente, metais pesados e nutrientes. Os compostos org?nicos estabilizados atingiram a rela??o C/N de 10,4/1 na pilha I e 10,4/1 na pilha II, mostrando-se como bons condicionantes de solo, apresentando potencial para melhorar as propriedades f?sicas de qualquer solo e o pH de solos ?cidos, j? a pilha III apresentou no final do processo rela??o C/N 26/1, est? alta rela??o pode ser associada ao tamanho da pilha III, alterando desta forma as condi??es ideais para ocorr?ncia do processo. Os teores de metais pesados analisados nos compostos foram inferiores aos estabelecidos pela instru??o normativa SDA, N? 27 de 05 de Junho de 2006. O uso de podas de arvores e gramas, utilizadas na compostagem em pequena escala, ao mesmo tempo em que gerou um composto de qualidade no produto final do processo, tamb?m criou uma condi??o importante para um correto dimensionamento das pilhas de compostagem. Nas condi??es estudadas n?o ? aconselh?vel utilizar pilhas com altura de 1,00 m de altura e 2,00 m de di?metro, pois estas n?o impedem a r?pida dissipa??o de calor e assim n?o se consegue um bom produto no final da compostagem. O processo de compostagem no galp?o da associa??o e a elabora??o da cartilha viabilizou o desenvolvimento de uma tecnologia alternativa de gera??o de renda para os associados da ACREVI

De acordo com essa lei, os munic?pios devem incentivar a operacionaliza??o da coleta seletiva com a participa??o de entidades de catadores de materiais recicl?veis, objetivando a inclus?o social desses trabalhadores. Por?m, as a??es planejadas nesse sentido nem sempre alcan?am os objetivos legais, visto que inserem estes trabalhadores no contexto da coleta oficial, mas os mantem despidos de certos direitos laborais b?sicos que proporcionariam a concretiza??o do Trabalho Decente. Este deve ser compreendido, segundo a Organiza??o Internacional do Trabalho, como o labor devidamente remunerado e exercido em condi??es de liberdade, equidade, seguran?a e apto a proporcionar uma vida digna ao trabalhador. Neste sentido, a presente pesquisa investigou o processo de efetiva??o das diretrizes da Pol?tica Nacional de Res?duos S?lidos no munic?pio do Natal, a partir da an?lise da inser??o socioprodutiva dos catadores de materiais recicl?veis. Fundamentado no m?todo qualitativo, o estudo utilizou como principais percursos metodol?gicos a consulta bibliogr?fica e documental. Na pesquisa de campo realizada entre os anos de 2013 e 2014 nas cooperativas de catadores de Natal, foram realizadas observa??es in loco do trabalho da cata??o, bem como entrevistas semiestruturadas com representantes das organiza??es pesquisadas. A fim de investigar a efetiva??o do Trabalho Decente no cotidiano da cata??o, foram estudadas as a??es municipais para inclus?o de catadores em Natal, investigando-se tanto a gest?o municipal, quanto as cooperativas de catadores, com a finalidade de refletir acerca dos avan?os e dificuldades vivenciadas no trabalho da coleta seletiva sob a chancela da municipalidade. Verifica-se que, mesmo apoiadas pelo poder p?blico, as cooperativas atuantes no munic?pio de Natal ainda enfrentam dificuldades de diversas ordens. O desempenho do trabalho oferece riscos aos catadores, sem um ambiente de trabalho seguro e/ou adequado ? sa?de daqueles trabalhadores. Persistem ainda o estigma da ocupa??o e a baixa renda obtida pelos indiv?duos, o que distancia a atividade estudada dos par?metros do Emprego Verde e Trabalho Decente. Por outro lado, a pesquisa apontou potencialidades como a busca incessante das cooperativas pela obten??o de melhorias para os trabalhadores. / The integrated management of municipal solid waste in Brazil is held legally responsible by the city council administration. This is done since the year 2010 with the publication of the National Solid Waste Policy term. According to the policy and law, each city must encourage the implementation of selective collection and the participation of waste picker?s entities aiming social inclusion. However, these actions haven?t yet reached its legal aims. These workers are considered regarding collection actions but are stripped of certain basic labor rights not in conformation with the Decent Work concept. This type of work, according to International Labour Organization, must be seen as work that is properly paid for and must be done regarding conditions of freedom, equity, security and able to provide workers with a dignified life conditions. Thus, this work aims to investigate the implementation process regarding the Solid Waste National Policy in Natal-Rio Grande do Norte in Brazil. This is done considering socio-productive insertion of recyclable material collectors. The research is substantiated by a qualitative approach as well as documental and bibliographical research. A field research considering the cooperatives as well ?in locco" observation and semi-structured interviews were carried out between the time span of 2013 and 2014. In order to investigate decent daily working conditions the research emphasized municipal management actions in Natal towards social inclusion that aim to reflect on the progress and difficulties experimented. It is seen that even when these cooperatives receive government support there are still important struggles that need to be overcome. The worker?s tasks are risky, the work environment in not safe or is adequate in terms of health issues. There is the stigma of it being considered an occupational task, the low individual income distancing the activity regarding parameters of the Green Employment and Decent Work concept. On the other hand, the survey showed potential as the relentless pursuit on behalf of the cooperatives that still search better work condition improvement.

The aim of this research is to study problematic of the management of solid waste under the point of view of the environmental awareness and the participation of the population in a city of Brazil. In this matter, the target of the work is focusing on the strategy of solid waste management, through the attitudes and the respondents behaviors to aid in the making decision of the public manager related to the implantation of a selective collection program in Natal/RN. The methodology used in this work constitutes in the application of a questionnaire with scales of the type Likert being constituted of variables that compose the aspects of attitudes and of behaviors, besides a social-demographic scale. For analysis statistics is used the Pearson s Chi-Square Method in order to verify the dependence of the associations between the social-demographic variables and the attitude and the behavior ones. The results appear for a larger participation in a SCP, since this provides a better quality of life of the population (28,3 %), followed for offering a financial advantage (27,3%). Other results indicate the existence of the variables that exercise influence on the environmental awareness of the population to its demographic aspects / O presente estudo insere-se na tem?tica ambiental internacional, abordando a gest?o integrada de res?duos s?lidos e a participa??o dos atores sociais na busca do desenvolvimento sustent?vel atrav?s de sua conscientiza??o ambiental. Descreve ainda a conscientiza??o em integrar-se a um Programa de Coleta Seletiva PCS de res?duos s?lidos em parceria com o poder p?blico municipal, no desenvolvimento de a??es conjuntas que resultem em melhores alternativas de gest?o para os res?duos nos centros urbanos, proporcionando melhor qualidade de vida para a popula??o e preserva??o do meio ambiente. O objetivo desta pesquisa ? estudar a problem?tica da gest?o de res?duos s?lidos sob o ponto de vista da conscientiza??o e participa??o ambiental da popula??o em uma cidade do Brasil. Desta forma, o escopo do trabalho versa sobre a estrat?gia de gest?o de res?duos s?lidos, atrav?s das atitudes e comportamentos dos entrevistados para auxiliar na tomada de decis?o do gestor p?blico quanto ? implanta??o de um programa de coleta seletiva em Natal/RN. A metodologia empregada neste trabalho constitui na aplica??o de um question?rio com escalas do tipo Likert constituindo-se de vari?veis que comp?em os aspectos atitudinais e comportamentais, al?m de uma escala s?cio-demogr?fica. Foi utilizado na an?lise estat?stica o m?todo Chi-Square de Pearson de modo a verificar a depend?ncia das associa??es entre as vari?veis s?cio-demogr?ficas e as vari?veis atitudinais e comportamentais. Os resultados apontam para uma maior participa??o em um PCS, desde que este proporcione uma melhor qualidade de vida da popula??o (28,3 %), seguido por oferecer uma vantagem financeira (27,3%). Outros resultados indicam a exist?ncia de vari?veis que exercem influ?ncia sobre a conscientiza??o ambiental da popula??o quanto ao seus aspectos demogr?ficos

The sample preparation for analysis had been make in the laboratories of geology of the UFRN. This samples procedures consists in register, dry, bolt and send to analysis in external laboratory (LAKEFIELD GEOSOL) in Belo Horizonte (MG, Brazil). The studied area involves the rivers Trairi, Arar? and N?sia Floresta lagoon, that empties in the sea, situated in the Rio Grande do Norte State. The study objects (Rivers Trair?, Arar? and N?sia Floresta lagoon) receive influences from urban dumpies, agrotoxics and fertilizer, shrimps tank, pastoral, with this, the concentrations of metals (Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, P, Zn) (except phosforus) in some points of the study area had been above of the value of reference what it leads to classify them as not polluted to moderately polluted, as the calculated Igeo. In front of discussed, can say about the environmental problems found in Trairi, Arar? and N?sia Floresta Lagoon are still in small scale, since when regard the studied ?rea is over human activity effects / Foram determinadas as concentra??es dos metais (Al, Ba, Cd, Cr, Cu, Fe, Mn, Ni, Pb, Zn ) e do fosf?ro (P) analisadas atrav?s de Espectr?metro de Massa com Plasma Indutivamente Acoplado para fra??o fina, < 0,063 mm, em 22 amostras. A prepara??o das amostras para an?lise foi realizada nos Laborat?rios de Geologia da UFRN e consistiu em cadastrar, secar, peneirar e enviar para an?lise em laborat?rio externo (LAKEFIELD GEOSOL), em Belo Horizonte (MG). A ?rea estudada corresponde aos rios Tra?ri, Arar? e lagoa N?sia Floresta, que des?guam no mar, situados no Estado do Rio Grande do Norte. Os objetos de estudo (Rios Trair?, Arar? e lagoa N?sia Floresta) recebem influ?ncias de lixos urbano, agrot?xicos e adubos, viveiros de camar?es e pastoril; com isto, as concentra??es destes metais em alguns pontos da ?rea de estudo ficaram acima do valor de refer?ncia classificando-os como n?o polu?dos a moderadamente polu?dos, conforme o Igeo calculado. Diante dos dados obtidos conclui-se que os problemas ambientais encontrados nos rios Tra?ri, Arar? e lagoa N?sia Floresta s?o ainda de pequena escala, mesmo quando se considera que na ?rea estudada a atividade humana ? intensa
