In order to achieve this goal a research methodology approach was set. The initial stage of the research methodology was based on a literature review on which it was observed that the CP can be linked with corporate sustainable once it prevents pollution and reduces the operational risks among employees, community and environment. In addition, CP can useful for companies position within competitive position as well as being applied to process, products and services. In order to observe these factors, CP was used within food industry (Company 1), textile industry (Company 2) and in a car dealer (Company 3). Regarding the results, Company 1 changed its raw material as well as implementing housekeeping (control use of water, energy and condensed milk). In Company 2, it was observed the three levels of CP. In other words, housekeeping (e.g. cutting process and manipulation of chemical products), changing technology (high pressure washing machine) and internal and external recycling. In addition, Company 3 considered only level 3 external recycling. As consequence, it was observed that can be applied either within industry as well as service sector. Unfortunately, it was not possible to observe any social gains on a monetary basis. This is due to limitations of the CP methodology and study complexity. Therefore, it was observed improvements regarding to social, environmental and economic areas. Nevertheless, it is necessary more commitment from top level management in order to consider CP like effective sustainable tool / O presente estudo teve como objetivo avaliar a Produ??o mais Limpa como uma ferramenta em busca da sustentabilidade empresarial, atrav?s de uma s?rie de estudos de m?ltiplos casos em empresas do Estado do Rio Grande do Norte. Para atingir este objetivo, primeiramente, foi efetuada uma revis?o da literatura pertinente, na qual foi observado que a PmL relaciona-se com a sustentabilidade empresarial, uma vez que de forma continuada, previne a gera??o de desperd?cio e reduz os riscos das opera??es sobre os funcion?rios, comunidade e meio ambiente. Al?m disto, a PmL contribui para posicionar as empresas em um cen?rio competitivo, podendo ainda ser aplicada aos processos produtivos e servi?os. Para se observar tais afirma??es, a ferramenta foi aplicada em uma ind?stria de alimentos (Empresa 1), em uma ind?stria t?xtil (Empresa 2), al?m de uma concession?ria de ve?culos (Empresa 3). Quanto aos resultados, na Empresa 1 foi contemplada a substitui??o de mat?ria-prima (farinha) e Housekeeping (controle do uso de ?gua, energia e leite condensado). J? a Empresa 2 foi poss?vel contemplar os tr?s n?veis de PmL, atrav?s de pr?ticas de Housekeeping (no corte e manipula??o de subst?ncias qu?micas); modifica??o tecnol?gica (instala??o de um lavador com press?o das telas de estampagem); reciclagem interna (reaproveitamento de retalhos) e reciclagem externa (fabrica??o de fuxico). Por fim, na Empresa 3, devido ao escopo estabelecido foi contemplado apenas o N?vel 3 M reciclagem externa (com segrega??o na fonte e reciclagem externa). Desta forma, observou-se que a PmL pode ser aplicada sem restri??es tanto em empresas industriais quanto prestadoras de servi?o. Enfatiza-se, ainda que n?o foi poss?vel quantificar os ganhos sociais obtidos em uma escala monet?ria, por limita??es da pr?pria ferramenta PmL e pela complexidade do estudo. Portanto, frente a analise da aplica??o da ferramenta Produ??o mais Limpa nas empresas estudadas, foi evidenciado melhoria nas vertentes ambiental, social e econ?mica, preconizadas pela sustentabilidade empresarial. Entretanto, faz necess?rio mais transpar?ncia da alta administra??o no comprometimento com continuidade das a??es, para diante disto, melhor enquadrar a PmL

(IBGE, 2008). The city is also inside Cod?-MA micro-region. The city is located in one of the lacking area in Brazil, where the Human Development Index (IDH) is approximately 0,558. It does not present an adequate model of management when talking about solid residue collecting. All of the solid residue produced and collected in the city is stored in an open area that they call lix?o , which is located in a residence area in the suburbs. Because of that, a problem that involves public health and environmental areas, we understand it is necessary to investigate the way the local government treats and manages the solid residue collecting, as well as, the social, economical and productive reality of those who are directly involved in the collecting itself, its productive chain of the material, including the handling, transportation and its final destiny. It means a social, productive, economical diagnosis, that in a such way,the local society and the organs of inspection can act in a better way to control the problems that include solid urban residue and come from a bad administration. That way, this work proposes to carry out a study that has as result a diagnosis with feasible alternatives on management, taking as basis, social and economical aspects that compound this productive chain. This work can bring great contributions to a better local reality through the introduction of an integrated and supported system of management of solid residue that includes a selective collecting and the creation of a sanitary area. Taking that into consideration, we can contribute to minimize the environmental impacts in Cod? Novo, caused by the garbage / A pesquisa foi realizada na ?rea urbana do munic?pio de Cod?

O munic?pio n?o disp?e de um modelo adequado de gerenciamento dos res?duos s?lidos. Todos os res?duos s?lidos, produzidos no munic?pio, s?o despejados em um lix?o a c?u aberto, situado em bairro residencial da periferia da cidade. Por se tratar de um problema de grande amplitude, que envolve a sa?de p?blica e o meio ambiente, entende-se que ? necess?rio investigar o modo de gerenciamento dos Res?duos S?lidos do munic?pio, bem como a realidade s?cio-econ?mica e produtiva da popula??o de catadores, mas tamb?m a cadeia produtiva deste material, incluindo seu manejo, transporte e sua destina??o final, ou seja, um diagn?stico s?cio-produtivo-econ?mico, Esse diagn?stico pode Contribuir para que a sociedade local e os ?rg?os de fiscaliza??o realizem a??es de controle dos problemas gerados pela m? gest?o dos res?duos s?lidos urbanos.

Nessa perspectiva, esse estudo tem por objetivo investigar e conhecer o papel que os cons?rcios, em especial o Cons?rcio P?blico Regional de Res?duos S?lidos do Serid?/RN, t?m na gest?o dos res?duos, com o prop?sito de observar suas fortalezas e debilidades, com o intuito de concluir se estes s?o uma solu??o adequada para a problem?tica dos res?duos s?lidos. Ao estudarmos uma regi?o que est? passando por um processo de organiza??o institucional pautada nos res?duos s?lidos, o foco transformou-se em um ponto de investiga??o acad?mica interessante. Se tratando de uma pesquisa qualitativa, foram realizadas leituras de autores pertinentes ao objeto e dos seguintes marcos legais, a saber: a Pol?tica Nacional de Saneamento B?sico (Lei n? 11.445/2007), a Pol?tica Nacional de Res?duos S?lidos (Lei n? 12.305/2010) e a Lei de Cons?rcios P?blicos (Lei n? 11.107/2005). A regi?o consorciada possui cerca de 290.000 habitantes, sendo geradas 40.000 toneladas de res?duos ao ano. Quanto ? destina??o final dos res?duos, todos os munic?pios da regi?o depositam seus res?duos a c?u aberto, ou seja, em lix?es. Na an?lise sobre o Cons?rcio do Serid?, foi identificado um rol de quest?es que est?o dificultando a sua implementa??o. As demandas passam, principalmente, pela esfera pol?tica, mas tamb?m por aspectos financeiros, t?cnicos e log?sticos. Espera-se que, com a efetiva??o do Cons?rcio atrav?s da constru??o das suas estruturas de apoio (Esta??es de transbordo e Aterro Sanit?rio), um novo modelo de gest?o dos res?duos s?lidos seja implantado. / The problem of solid waste that involves the management, the management and the allocation of these is an issue that permeates all spheres of society, which denotes environmental implications that contribute to the discussion of the environmental crisis in progress. From this perspective, this study aims to investigate and understand the role that consortia, especially the Regional Public Waste Consortium Solid Serid?/RN have waste management, in order to observe their strengths and weaknesses in order to conclude whether they are an appropriate solution to the problem of solid waste. In studying a region that is undergoing a process of institutional organization guided in the solid waste, the focus turned into an interesting academic research point. Since this is a qualitative research, readings were taken of relevant authors to the object and the following legal frameworks, namely: the National Basic Sanitation Policy (Law n? 11.445/2007), the National Policy on Solid Waste (Law n? 12.305/2010 ) and the Law on Public Consortia (Law n? 11.107/2005). The consortium region has about 290.000 inhabitants, generated 40.000 tons of waste a year. As for the final disposal of waste, all municipalities in the region deposit their waste in the open, or in garbage dumps. In the analysis of the Consortium Serid?, a list of issues that are hindering their implementation has been identified. The demands come mainly from the political sphere, but also financial, technical and logistical. It is expected that with the realization of the Consortium by building its supporting structures (overfill Station and Landfill), a new model of solid waste management is implemented.

Esta crise tem como principal caracter?stica sua multidimensionalidade, passa por quest?es econ?micas, culturais, ?ticas, ambientais e, sobretudo, pol?tica. No intuito de estudar em profundidade esta crise que se manifesta pelo processo de urbaniza??o e tem nas metr?poles sua exacerba??o, foi realizado estudo te?rico conceitual acerca do sentido de desenvolvimento sustent?vel aplicado ? realidade das cidades, extraindo desse debate os conceitos: desenvolvimento territorial sustent?vel, sustentabilidade administrativa e sustentabilidade pol?tica. A fim de testar a aplicabilidade pr?tica destes conceitos te?ricos, estudou-se em profundidade a realidade da gest?o dos res?duos s?lidos urbanos na metr?pole de Natal. De acordo com o recente debate te?rico, os res?duos compreendem um setor da crise ambiental urbana que melhor representa a rela??o entre homem e meio ambiente. Garantindo a multidimensionalidade das quest?es ambientais por meio do Saber Ambiental, foi feito um estudo qualitativo em profundidade, correlacionando os conceitos de desenvolvimento territorial sustent?vel, governan?a metropolitana e Saber Ambiental aplicado aos res?duos s?lidos. Os resultados apontam para os reais desafios das administra??es p?blicas municipais em compreender, agir e mudar a in?rcia na qual v?m operando nas ?ltimas d?cadas. Os resultados tamb?m demonstraram a import?ncia de transformar as quest?es ambientais, em desafios pol?ticos, ou seja, embate por ideias, refer?ncias ideol?gicas e ?ticas. / Nowadays the rapid growth of urban centers, the accumulation of social and environmental demands, the relationship between public policy and increasingly complex problems accentuates the feeling that cities undergo an urban crisis. This crisis is especially characterized by its multidimensionality, which goes through economic, cultural, ethical, environmental and, above all, political issues. In order to study the core of this crisis that is manifested by the urbanization process and has in its exacerbation on the metropolitan areas was conducted conceptual and theoretical study of the meaning of sustainable development applied to the everyday reality of cities, extracting from this debate concepts, such as: sustainable territorial development, administrative sustainability and political sustainability. Looking forward to test this the practical applicability of these theoretical concepts studied, an empirical study was done on the reality of metropolitan solid waste in Natal, Rio Grande do Norte, Brasil. According to the recent theoretical debate, the waste comprises a sector of the urban environmental crisis that best represents the relationship between man and environment. Ensuring the multidimensionality of environmental issues through the ?Saber Ambietal? (LEFF, 2005), was made a extensive qualitative study correlating the concepts of sustainable territorial development, metropolitan governance and ?Saber Ambiental? applied on solid waste. The results point to the real challenges of municipal government in understanding the real situation, take action and change the inertia in which have operated in recent decades. The results also showed the importance of transforming environmental issues in political, in other words, struggle for ideas, ideological and ethical references.

Such tool has been used by companies to face the problems caused by solid waste, in particular green coconut waste, which is constantly among the material discarded by society (companies/ consumer). It is a typical tropical fruit whose fresh water is very benefic for human health, and its popularization has caused a progressive increase of its consumption. Following this stream of thought, this present work came up with an analysis of strengths, weaknesses, threats, and opportunities SWOT analysis on green coconut solid waste management at two agribusiness companies in the state of Rio Grande do Norte (RN), Brazil, aiming to know the challenges and the potentials of this kind of waste. According to the approach of the problem, this work fits a descriptive, exploratory, and qualitative research. The data collection was obtained by a questionnaire and a structured interview, in order to evaluate the strategic posture of agribusiness companies through SWOT analysis, which is an English acronym for Strengths, Weaknesses, Opportunities and Threats. The SWOT analysis is an effective tool to analyze the internal and external environment of an organization. This tool contributes to locate the company at the environment in question and when well applied it enables the detection of mistakes, the strengthening of correct procedures, the avoidance of threats, and the bet on opportunities. The studied agribusiness industries have very similar profiles, such as a long business life span, and a strategy that extends the useful life of the fruit, by using its waste for the manufacturing of new subproducts. In both, the daily quantity of waste resulted of this process reaches approximately 20 thousand units of the fruit in high season, being necessary a focus directed at use and/or treatment of these waste. Further to SWOT analysis, it was ascertained that the agribusiness company A works through a defensive marketing strategy and acts vulnerably, in other words, unable of acting before this market segment, for it has decided to stop using the waste due to a lack of equipment and technology. On the other hand, the agribusiness company B has incorporated an offensive marketing strategy because even not possessing equipments, technology, and appropriated internal installations, it still insists on use and benefits of green coconut waste in its agribusiness. Thus, it is considered that the potential of green coconut waste management for the production of several subproducts reduces the impacts produced by inappropriate placement and generates profits in a short, medium and long term. Such profits being tangible and intangible, as the interest for sustainability actions is not only a matter of obtaining return on capital, but it is an important question in order to move on into business, since it is not enough to have quality on products and process nowadays. It is necessary to establish socio-environmental practices aiming the image of the company as the prevailing role on consumers buying decision / A causa ambiental, na atual conjectura, est? alterando o posicionamento das empresas que est?o praticando ou minimamente adotando a gest?o ambiental. Tal ferramenta est? sendo utilizada nas empresas para enfrentar a problem?tica causada pelos res?duos s?lidos, dentre eles os res?duos do coco verde, presente constantemente no material descartado pela sociedade (empresas/consumidor). ? uma fruta tipicamente tropical, cuja ?gua fresca traz muitos benef?cios ? sa?de humana e sua populariza??o desencadeou um aumento progressivo do seu consumo. Seguindo esse racioc?nio, o presente trabalho prop?s analisar os pontos fortes, fracos, amea?as e oportunidades an?lise de SWOT - no gerenciamento dos res?duos s?lidos do coco verde em duas agroind?strias situadas no Estado do Rio Grande do Norte RN (Brasil), com intuito de conhecer os desafios e potencialidades do aproveitamento desses res?duos. Do ponto de vista da abordagem do problema, este trabalho se enquadra como uma pesquisa qualitativa, explorat?ria e descritiva. A coleta de dados foi realizada com a aplica??o de um question?rio e entrevista estruturada sendo avaliada a postura estrat?gica das agroind?strias atrav?s da an?lise SWOT, que ? uma sigla oriunda do idioma ingl?s, ? um acr?nimo de For?as (Strengths), Fraquezas (Weaknesses), Oportunidades (Opportunities) e Amea?as (Threats). A an?lise SWOT ? uma ferramenta eficaz para analisar o ambiente interno e externo de uma organiza??o. Essa ferramenta contribui para situar a empresa no ambiente em quest?o e quando bem aplicada ? poss?vel detectar erros, fortalecer acertos, driblar as amea?as e apostar nas oportunidades. As agroind?strias estudadas possuem perfis bastante similares como: tempo de vida no mercado e por seguir uma linha de estrat?gia que prolonga a vida ?til do fruto com aproveitamento de seus res?duos para fabrica??o de novos subprodutos. Em ambas, a quantidade di?ria de res?duos gerados alcan?a aproximadamente 20 mil unidades do fruto em alta esta??o, tornando necess?rio um enfoque direcionado ao aproveitamento e/ou tratamento desses res?duos. Em rela??o ? an?lise de SWOT, constatou-se que a agroind?stria A opera com capacidade defensiva atuando assim com vulnerabilidade, ou seja, impossibilitada de atuar diante desse segmento de mercado, por ter decidido parar de aproveitar os res?duos por falta de equipamentos e tecnologias adequadas. Em contrapartida a agroind?stria B est? utilizando a estrat?gia de capacidade ofensiva de mercado, pois, mesmo n?o possuindo equipamentos, tecnologias e instala??es internas apropriadas, ainda assim, persistem no aproveitamento e beneficiamento dos res?duos do coco verde em sua agroind?stria. Assim, considera-se que o potencial do gerenciamento dos res?duos do coco verde para a produ??o de uma diversidade de subprodutos reduz os impactos produzidos pela disposi??o inadequada e geram lucro em curto, m?dio e longo prazo. Lucros esses tang?veis e intang?veis, j? que o interesse por a??es de sustentabilidade n?o ? s? uma quest?o de obten??o de retorno financeiro, mas ? quest?o fundamental para manter-se no neg?cio, posto que hoje em dia n?o basta possuir qualidade nos produtos e processos. ? preciso estabelecer pr?ticas socioambientais, tendo em vista a imagem da empresa como papel preponderante na decis?o de compra dos consumidores

It is discarded after use. The disposal of these fluids causes one of the most difficult environmental problems in the world. This study aims to promote liquid phase separation of drilling fluids, which have circulated in oil wells, and enable this recovered liquid to formulate a new fluid. For this, non-ionic surfactants were used in order to select the best outcome in phase separation. Five real water-based drilling fluids were utilized, which were collected directly from the fields of drilling oil wells, classified as polymeric fluids. The methodology used consisted in combining the fluid with surfactant and then subjecting it to a process of centrifugation or decantation. The decantating tests were scheduled through experimental planning 23 and 32, using as variables the percentage (%) of surfactant utilized and the stirring time in minutes. The surfactants used were ethoxylated nonylphenol and lauryl alcohol ethoxylated with different degrees of ethoxylation. Phase separation was monitored first by tests of stability, and subsequently by the height of the interface in beakers of 100 mL. The results showed that from the surfactants studied, the lauryl alcohol ethoxylated with 3 ethoxylation units has been the most effective in the phase separation process of the drilling fluids tested. The statistical tool used was of great industrial value regarding the programming phase separation in drilling fluids. In conclusion, the liquid phase separated using surfactant can be reused for a new formulation of drilling fluid with similar properties of a new fluid, assuring its efficiency. And in the resulting analysis it is also suggested that the adsorption is the mechanism that leads the phase separation, with surfactant adsorbing in the active solids / O fluido de perfura??o, utilizado para auxiliar na opera??o de perfura??o de po?os de petr?leo, acumula s?lidos inerentes a forma??o ? medida que ? circulado no po?o durante a perfura??o, interferindo no seu desempenho durante a opera??o. Assim, ap?s o uso ele ? descartado, gerando um dos passivos ambientais mais dif?ceis de recuperar em todo o mundo. O presente estudo tem por finalidade promover a separa??o da fase l?quida de fluidos de perfura??o que j? foram circulados em po?os de petr?leos, habilitando seu uso para formula??o de um novo fluido. Para isso, foram utilizados tensoativos n?o i?nicos a fim de selecionar o que melhor atuasse na separa??o de fases. Foram utilizados cinco fluidos de perfura??o base ?gua, reais coletados diretamente nos campos de perfura??o de po?os de petr?leo, classificados como fluidos polim?ricos. A metodologia utilizada constitui-se basicamente em aditivar o fluido com o tensoativo e depois submet?-lo ? um processo de centrifuga??o ou decanta??o. Os ensaios de decanta??o foram programados atrav?s do planejamento experimental 23 e 32, utilizando como vari?veis o % de tensoativo utilizado e o tempo de agita??o em minutos. Os tensoativos utilizados foram o nonilfenol etoxilado e o ?lcool laur?lico etoxilado, ambos com diferentes graus de etoxila??o. A separa??o de fases foi acompanhada inicialmente por ensaios de estabilidade e, posteriormente, pela altura da interface em provetas de 100 mL. Os resultados obtidos mostraram que, dentre os tensoativos estudados, o ?lcool laur?lico etoxilado, com 3 unidades de etoxila??o, foi o que atuou de forma mais eficiente no processo de separa??o de fases dos fluidos de perfura??o estudados. A aplica??o de planejamentos estat?sticos pode ser uma ferramenta de grande valor industrial no que diz respeito a programa??o de separa??o de fases em fluidos de perfura??o. Concluiuse que a fase l?quida separada utilizando tensoativos pode ser reutilizada na formula??o de um novo fluido de perfura??o, com propriedades semelhantes a de um fluido novo, garantindo a efic?cia do mesmo. Com a an?lise dos resultados sugere-se, ainda, que a adsor??o ? o mecanismo que governa a separa??o de fases, com o tensoativo adsorvendo-se nos s?lidos ativos / 2020-01-01

The evaluation was preceded by literature review in public databases and academic literature on the economic, social, cultural, environmental situation, policy and solid waste management in the municipality. Thus, aiming to add value to research and enhancing the systemic view, were introduced information on the understanding of 44 social representatives, residents and collectors of recyclable materials on municipal solid waste management, through a questionnaire. In addition, field observations were carried out in 22 of the 44 districts of the municipal headquarters and in eight districts. The array of indicators used is composed of six dimensions of sustainability, key questions and 42 indicators of which five are indicators of the political dimension, four technological, four in the economic / financial dimension, thirteen environmental / ecological dimension, ten dimension of knowledge (Environmental Education and Social Mobilization) and six in the dimension of social inclusion. The matrix also presents three descriptors for each indicator totaling 126, with space for setting of bookmark note that varies from 0 to 5. After application of the matrix, the level of sustainability was 4.1, corresponding to a low- sustainability, and the financial and social inclusion the most unsustainable dimensions. The results found convenes public managers for emergency decision making, such as the development of solid waste management plan, as required by National Policy on Solid Waste and draws attention to the importance of popular participation in the Municipal Solid Waste Management. Against the backdrop, recommendations for sustainable management were proposed. / A pesquisa buscou avaliar a sustentabilidade da Gest?o de Res?duos S?lidos Urbanos no munic?pio de Feira de Santana, Bahia, por meio da aplica??o da matriz de indicadores de sustentabilidade proposta por Santiago e Dias (2012). A avalia??o foi precedida de revis?o bibliogr?fica em bases p?blicas e literatura acad?mica sobre a situa??o econ?mica, social, cultural, ambiental, pol?tica e manejo dos res?duos s?lidos do munic?pio. Dessa forma, objetivando agregar valor ? pesquisa e potencializar a vis?o sist?mica, foram introduzidas informa??es sobre a compreens?o de 44 representantes sociais, moradores e catadores de materiais recicl?veis, sobre manejo de res?duos s?lidos urbanos, por meio da aplica??o de question?rio. Al?m disto, foram realizadas observa??es de campo em 22 dos 44 bairros da sede municipal e nos 8 distritos. A matriz de indicadores utilizada ? composta por seis dimens?es da sustentabilidade, perguntas-chave e 42 indicadores dos quais, cinco s?o indicadores da dimens?o pol?tica, quatro da dimens?o tecnol?gica, quatro da dimens?o econ?mica/financeira, treze da dimens?o ambiental/ecol?gica, dez da dimens?o do conhecimento (Educa??o Ambiental e Mobiliza??o Social) e seis da dimens?o da inclus?o social. A matriz apresenta tamb?m tr?s descritores para cada indicador totalizando 126, com espa?o para defini??o da nota do indicador, que varia de 0 a 5. Ap?s a aplica??o da matriz, o n?vel de sustentabilidade encontrado foi de 4,1, que corresponde a uma baixa sustentabilidade, sendo as dimens?es financeira e inclus?o social as mais insustent?veis. O resultado encontrado convoca os gestores p?blicos para tomada emergencial de decis?o, como a elabora??o do plano de gest?o de res?duos s?lidos urbanos, conforme determina a Politica Nacional de Res?duos S?lidos e chama aten??o para a import?ncia da participa??o popular na Gest?o dos Res?duos S?lidos Urbanos. Diante do cen?rio, recomenda??es para Gest?o Sustent?vel foram propostas.
