The main one is the industrial activity and its products. In this context , it is noteworthy the construction , responsible for the high demand of non-renewable resources at the beginning of the production chain, the processes which depend on high energy consumption and high waste generation. To reconcile the potentially polluting activities to sustainable development , the National Environmental Policy Act created the environmental licensing as a tool to be used in order to minimize negative environmental impacts. Considering that Brazil was the country characterized by bureaucratic processes, the aim of this paper is to analyze the legal protection of the environment in the context of sustainable development, with emphasis on the role of the environmental license for the construction of condominiums and subdivisions in the city of Mossley and how effective the instrument responsible for environmental preservation. To consolidate research carried out a descriptive analysis of the responses obtained from the semi-structured questionnaires answered by the Director of Environmental Control of the Secretariat of the Environmental Management System (EMS ) in the city of Natal, three officials said Undersecretary responsible for overseeing projects that are in licensing and the managers of the selected contractors process. At the end of the survey it was found that the SGA has a body of compromised servers to protecting the environment and performs a well- coordinated work to achieve sustainable development in construction. It was also an absence of servers to carry out the inspection activities of the environmental licensing. Regarding companies that operate in the construction business, they were emphatic in stating the importance of environmental permits for the preservation of the environment, but that does not justify performing the procedure without clamor arising from excess requested documents , increasing the cost of work and delaying the granting of licenses. Given what was searched, it was found that environmental licenses in construction reduce negative environmental impacts. However, it could be more effective if there were a greater number of tax in Town of Mossoró / Diversas atividades humanas contribuem para a escassez dos recursos naturais. A principal delas é a atividade industrial e seus produtos. Neste contexto, destaca-se a construção civil, responsável pela alta demanda de recursos não renováveis no início de sua cadeia produtiva, pelos processos que dependem de alto consumo energético e pela elevada geração de resíduos. Para compatibilizar as atividades potencialmente poluidoras com o desenvolvimento sustentável, a Política Nacional do Meio Ambiente criou o licenciamento ambiental como instrumento a ser utilizado com o fim de minimizar os impactos ambientais negativos. Tendo em vista ser o Brasil o país caracterizado por processos burocráticos, o objetivo desse trabalho é analisar a proteção jurídica do meio ambiente no contexto do desenvolvimento sustentável, com ênfase ao papel do licenciamento ambiental, para a construção dos condomínios e loteamentos no município de Mossoró e como instrumento responsável por efetivar a preservação ambiental. Para consolidar a pesquisa fora realizada uma análise descritiva, a partir das respostas obtidas pelos questionários semiestruturados respondidos pelo Diretor de Controle Ambiental da Subsecretaria da Gestão Ambiental (SGA) do município de Mossoró, por três funcionários da referida Subsecretaria responsáveis pela fiscalização dos empreendimentos que estão em processo de licenciamento e pelos gestores das empreiteiras selecionadas. Ao final da pesquisa constatou-se que a SGA possui um corpo de servidores comprometidos com a proteção do meio ambiente e realiza um trabalho bem articulado para atingir o desenvolvimento sustentável na construção civil. Detectou-se, ainda, a ausência de servidores para efetivar a atividade fiscalizatória do licenciamento ambiental. No tocante às empresas que atuam no ramo da construção civil, elas foram enfáticas ao afirmarem sobre a importância das licenças ambientais para a preservação do meio ambiente, mas justificaram que não realizam o processo sem clamores decorrentes do excesso de documentos solicitados, aumentando o custo da obra e atrasando a concessão das licenças. Diante do que foi pesquisado, verificou-se que as licenças ambientais na construção civil reduzem os impactos ambientais negativos. Contudo, poderia ser mais efetivo se houvesse um número maior de fiscais na Prefeitura Municipal de Mossoró

The principal aim of the present work is the characterization of the wastewater from the textile industry that process the indigo, located in the Industrial District of Natal-RN, to know the contaminante load of each stage of the process and the framing of the wastewater with the standards of act of receiving of the System of Treatment of Wastewater of the Industrial District of Natal-RN SITEL-DIN, operated for the Company of Waters and Sewers of the RN CAERN. It was analyzed the following properties and pollutants agents: temperature; pH; alcalinity; color; COD (Chemical Oxygen Demand); total and suspended solids; heavy metals, thermotolerants coliformes, turbidity, dissolved oxygen and electrical conductivity. As conclusion it is distinguished that the wastewater did not get resulted satisfactory, according to comparisons with other sources, in only three parameters: turbidity, dissolved oxygen and electrical conductivity, however none of these parameters is criteria of acts of receiving of the SITEL-DIN,therefore the wastewater if finds inside of normality. After the analysis of the obtained results it was verified that SITEL-DIN is indispensable for completing the wastewater treatment / A grande diversidade das atividades industriais t?xteis ocasiona, durante o processo produtivo, a gera??o de efluentes com caracter?sticas bastante complexas, variando de acordo com o tipo de processo industrial utilizado. O presente trabalho tem como objetivo principal a caracteriza??o do efluente l?quido de uma ind?stria de beneficiamento do ?ndigo t?xtil, localizada no Distrito Industrial de Natal-RN, para conhecermos a carga contaminante de cada etapa do processo e o enquadramento do efluente final com os padr?es de recebimento do Sistema de Tratamento de Efluentes L?quidos do Distrito Industrial de Natal SITEL-DIN, operado pela Companhia de ?guas e Esgotos do RN CAERN. Analisou-se as seguintes propriedades e agentes poluentes: temperatura, pH, alcalinidade, cor, DQO, s?lidos totais, s?lidos suspensos totais, metais pesados, coliformes termotolerantes, turbidez, oxig?nio dissolvido e condutividade el?trica. Como conclus?o destaca-se que o efluente final n?o obteve resultados satisfat?rios, segundo compara??es com outras fontes, em apenas tr?s par?metros: turbidez, oxig?nio dissolvido e Condutividade el?trica, por?m nenhum desses par?metros s?o crit?rios de recebimentos do SITEL-DIN, portanto o efluente final se encontra dentro da normalidade. Ap?s a an?lise dos resultados observamos ser indispens?vel ? exist?ncia do SITEL-DIN para tratamento final dos efluentes da ind?stria

Before being disposed of in water bodies, a pre-treatment of the effluent is carried out, which is sometimes ineffective. In order to be properly treated, physical and chemical properties of the effluent must be known, as well as the pollutant agents that might be present in it. This has turned out to be a great problem in the textile industry, for there is a variety of processes and the pollutant load is very diversified. The characterization of the effluent allows the identification of most critical points and, as a consequence, the most appropriate treatment procedure to be employed, may be chosen. This study presents the results obtained after characterizing the effluent of a textile industry that comprises knitting, dyeing and apparel sections, processing mainly polyester/cotton articles. In this work, twenty samples of the effluent were collected, and related to the changes in production. From the results, a statistical evaluation was applied, determined in function of the rate of flow. The following properties and pollutants agents were quantitatively analysed: temperature; pH; sulfides; chlorine; alcalinity; chlorides; cianides; phenols; color; COD (Chemical Oxygen Demand); TOC (Total Organic Carbon); oil and grease; total, fixed and volatile solids; dissolved, fixed and volatile solids; suspended, fixed and volatile solids; setteable solids and heavy metals such as cadmium, copper, lead, chromium, tin, iron, zinc and nickel. Analyses were carried out according to ABNT NBR 13402 norm, based upon Standard Methods for the Examination of Water and Wastewater. As a consequence, a global treatment proposal is presented, involving clean production practices as contaminant load reducer, followed by conventional (biological) treatment / A ind?stria t?xtil caracteriza-se pela diversidade de processos utilizados e gera??o de altos volumes de efluentes com alta carga poluidora. O efluente recebe um pr?-tratamento, muitas vezes insatisfat?rio e ? lan?ado no corpo d ?gua. Para que possa receber um tratamento, ? necess?rio conhecer as propriedades f?sicas e qu?micas do efluente, bem como os agentes poluentes presentes no mesmo. Isto tem sido um grande problema na ind?stria t?xtil, pois os processos utilizados s?o muitos e a carga poluente bastante diversificada. A caracteriza??o do efluente permite identificar os pontos mais cr?ticos e conseq?entemente a a??o mais adequada no seu tratamento. O presente estudo apresenta os resultados obtidos na caracteriza??o de um efluente de ind?stria t?xtil, composta de malharia, tinturaria e confec??o que processa principalmente poli?ster/algod?o. Neste estudo foram realizadas 20 coletas do efluente, procurando associ?-las ?s mudan?as na produ??o, e a partir destes resultados aplicou-se uma avalia??o estat?stica, determinada em fun??o da vaz?o. Analisou-se quantitativamente as seguintes propriedades e agentes poluentes: temperatura, pH, sulfetos, cloro, alcalinidade, cloretos, cianetos, fen?is, cor, DQO (demanda qu?mica de oxig?nio), COT (carbono org?nico total), ?leos e graxas, s?lidos totais, fixos e vol?teis, s?lidos dissolvidos, fixos e vol?teis, s?lidos suspensos, fixos e vol?teis, s?lidos sediment?veis e metais pesados como c?dmio, cobre, chumbo, cromo, estanho, ferro, zinco e n?quel. As an?lises foram realizadas de acordo com a norma ABNT NBR 13402 sendo as mesmas baseadas no Standard Methods for the Examination of Water and Wastewater . Como conseq??ncia, apresenta-se uma proposta de tratamento global, envolvendo pr?ticas de produ??o limpa, como redutor da carga contaminante, seguidas do tratamento convencional (biol?gico)
