A research in field have been realized inside building sites of companies in order to provide knowledge about the implemented and accomplish actions according to the resolution from CONAMA n?307. Trough the interview among the representations of the companies and photographic survey in loco, such as, what makes the companies implement this management, reutilization and recycling, transport and disposition. The present study had as objective: analyze the insertion of the used tools to residuals management, proposing improvements, in a way that it can be easily identified during the procedures execution in the building sites of the building companies of the city of Natal/RN. To reach the goal, in the first place a revision of the pertinent literature was performed; there for, it can be seen the relation between residues management and environment sustainability, once it happens in a continued way it may prevent the waste and reduces the risk that the activities way bring to the employees, community and environment; once found the great difficult faced with regard to labors, material, equipment, project, planning, costumer s interference, furnisher. And still, it could be verified wich materials generate greater indexes of residues in the works and the main occurrences of waste and loss. However a greater transparency is needed coming from the high administration in the commitment with the continued actions, to make it so, there must be a cultural change inside the company. There for there will be a greater productivity and quality of the under taking such as costumer s satisfaction / Devido a maior preocupa??o entre as atividades industriais desenvolvidas e os impactos resultantes sobre o meio ambiente, uma associa??o de in?meros fatores tem ocorrido, procedimentos para o gerenciamento eficaz das rela??es entre desenvolvimento econ?mico e meio ambiente vem sendo aperfei?oados. Foi realizado um trabalho de campo, dentro dos canteiros de obras das empresas para que se possa ter conhecimento das a??es implementadas e cumpridas segundo a Resolu??o do CONAMA n? 307. Atrav?s de entrevista junto a representantes da empresa e levantamento fotogr?fico in loco; assim como o que leva as empresas a implementar este gerenciamento, reutiliza??o e reciclagem, transporte e disposi??o. O presente estudo teve como objetivo analisar a inser??o das ferramentas utilizadas para o gerenciamento de res?duos, propondo melhorias, de forma que as mesmas possam ser mais facilmente identificadas durante a execu??o dos processos no canteiro de obras de empresas construtoras da cidade de Natal-RN. Para atingir este objetivo, primeiramente, foi efetuada uma revis?o da literatura pertinente, na qual foi observado que o gerenciamento de res?duos relaciona-se com a sustentabilidade ambiental, uma vez que de forma continuada previne a gera??o de desperd?cio e reduz os riscos das atividades sobre os funcion?rios, comunidade e meio ambiente; sendo constatadas as maiores dificuldades enfrentadas em rela??o ? m?o-de-obra, materiais, equipamento, projeto, planejamento, interfer?ncia do cliente, fornecedores. E ainda se pode constatar quais os materiais que geram maior ?ndice de res?duos nas obras e as principais ocorr?ncias das perdas e desperd?cios. Entretanto, se faz necess?ria maior transpar?ncia da alta administra??o no comprometimento com a continuidade das a??es, para que a partir disto possa haver uma mudan?a de cultura instalada nas empresas, gerando maior produtividade, qualidade dos empreendimentos e uma maior satisfa??o dos clientes

All the problems of waste generation becomes even more serious due to the ineffectiveness of treatment and final disposal of this waste, given that ways to manage these wastes can impact profoundly on the environment, contaminating soil, air, water. All the problems of waste generation becomes even more serious due to the ineffectiveness of treatment and final disposal of this waste, given that ways to manage these wastes can impact profoundly on the environment, contaminating soil, air, water. Thus, there is no way to think of ways to preserve and restore the environment regardless of the existence of waste management programs that allow the minimization of environmental impacts. In this context, the present study aimed to investigate the management of chemical waste in the Department of Animal Morphology and Physiology (DMFA) of the Federal Rural University of Pernambuco (UFRPE). And as specific objectives, seek to identify and quantify the situation of chemical waste generated in histology laboratories; propose and provide a guide for chemical waste management procedures in order to assist DMFA laboratories in a future implementation of a Chemical Waste Management Program (PGRQ). We used the case study method, where qualitative and quantitative data were collected, as well as observations in locus. The application of semi-structured questionnaires, with open and closed questions, was conducted from February 2015 to April 2015, and the record of the waste produced in laboratories, from November 2014 to March 2015. The survey results showed the need to prioritize actions aimed at proper management of chemical waste, so that UFRPE implement a chemical waste management Program, capable of treating the waste produced in its laboratories and thereby reducing environmental impacts generated by these. / No contexto de crise ambiental vivenciado pela humanidade, destacamos o aumento progressivo dos res?duos produzidos nas ?ltimas d?cadas, o qual tem demandando mudan?as nos assuntos socioecon?mico, cultural, legal e precipuamente, ambiental. Toda a problem?tica da gera??o de res?duos se torna ainda mais grave em raz?o da inefici?ncia dos tratamentos e disposi??o final adequada dos mesmos, tendo em vista que as formas de gerir estes res?duos podem impactar profundamente no meio ambiente, contaminando o solo, ar e recursos h?dricos. Deste modo, n?o h? como pensar em formas de preservar e recuperar o meio ambiente sem levar em considera??o a exist?ncia de programas de gerenciamento de res?duos que permitam a minimiza??o dos impactos ambientais. Neste contexto, a presente pesquisa teve por objetivo investigar a gest?o de res?duos qu?micos no Departamento de Morfologia e Fisiologia Animal (DMFA) da Universidade Federal Rural de Pernambuco (UFRPE). E como objetivos espec?ficos, buscamos identificar e quantificar a situa??o dos res?duos qu?micos gerados nos laborat?rios de histologia; propor e disponibilizar um guia de procedimentos de gerenciamento de res?duos qu?micos, a fim de auxiliar os laborat?rios do DMFA em uma futura implanta??o de um Programa de Gerenciamento de Res?duos Qu?micos (PGRQ). Utilizamos o m?todo de estudo de caso, onde foram levantados dados qualitativos e quantitativos, assim como observa??es in l?cus. A aplica??o de question?rios semiestruturados, com quest?es abertas e fechadas, foi realizada no per?odo de fevereiro de 2015 a abril de 2015, e o registro dos res?duos produzidos nos laborat?rios, no per?odo de novembro de 2014 a mar?o de 2015. Os resultados da pesquisa apontaram para a necessidade de priorizar a??es voltadas para o gerenciamento adequado de res?duos qu?micos, de modo que a UFRPE implemente um Programa de Gerenciamento de Res?duo Qu?mico, capaz de garantir o tratamento dos res?duos produzidos em seus laborat?rios e com isso a redu??o dos impactos ambientais gerados por estes.

However, it is from available data that the public executives should define the USW management. To contribute to the choice of a model for the management of USW in small municipalities, this study reviews the related literature, showing an overview of the final disposal of USW in small municipalities. Several data and researches are discussed, concluding that the available data, despite being provided by the public managers, who often attenuate the problem, should be considered for the proposition of policies to encourage the waste treatment / O panorama dos Res?duos S?lidos Urbanos (RSU) no Brasil, de maneira geral deixa a desejar face ? imensid?o do pa?s. No entanto, ? a partir dos dados existentes que o gestor p?blico deve embasar a gest?o dos RSU. Visando contribuir para a escolha do modelo de gest?o dos RSU em munic?pios de pequeno porte, o presente estudo revisa a literatura relacionada, mostrando como se d? a disposi??o final dos RSU em munic?pios de pequeno porte. S?o discutidas v?rias pesquisas, concluindo-se que os dados apresentados, muito embora sejam fornecidos pelos gestores, que muitas vezes minoram o problema, h?o de ser considerados para a proposi??o de pol?ticas de incentivo ao tratamento de res?duos
