A ecoefici?ncia ? uma estrat?gia de gest?o ambiental que tem como objetivo reduzir o consumo de recursos, reduzir o impacto sobre a natureza e fornecer aos clientes produtos e servi?os de maior qualidade. Para sua mensura??o foi utilizada a metodologia denominada Taxonomia CE7, sigla referente ?s ?sete compet?ncias da ecoefici?ncia?, que, adaptada ?s estrat?gias ambientais, mostrar? o n?vel de ecoefici?ncia em que os empreendimentos se encontram. A pesquisa de campo adota como objeto de estudo 44 MPEs da cadeia produtiva do petr?leo e g?s potiguar, integrantes do projeto ?cadeia produtiva do petr?leo, g?s e energia do RN?, desenvolvido pelo Servi?o Brasileiro de Apoio ?s Micro e Pequenas Empresas (Sebrae) do RN, que prestam servi?o ? Petrobras e que fazem parte da RedePetro RN. A coleta de dados ocorreu no per?odo de agosto a outubro de 2016, atrav?s do m?todo survey. Ao t?rmino do estudo, foram evidenciados a aus?ncia de MPEs ecoeficientes no encadeamento produtivo e que o melhor n?vel de entrega ocorreu para 15,91% dos empreendimentos que foram diagnosticados como ?quase ecoeficientes?. As estrat?gias ambientais que promovem a ecoefici?ncia s?o a efici?ncia energ?tica, o Plano de Gerenciamento de Res?duos S?lidos (PGRS), os cuidados ambientais na sele??o de fornecedores e o licenciamento ambiental. Por fim, a ecoefici?ncia n?o ? uma pr?tica de gest?o institucionalizada na realidade das MPEs desse encadeamento produtivo. / This thesis contribute to studies on environmental sustainability in the oil industry by measuring the eco-efficiency of Small Business of Supply chain oil and gas in Rio Grande do Norte. It also seeks to help maximize environmental efficiency, cost reduction, identification of method improvements in operational processes, adding value and strengthening business competitiveness in the region. Eco-efficiency is a management strategy that aims to reduce resource consumption, reduce the impact on nature and provide customers with higher quality products and services. For its measurement, we used the methodology called CE7 taxonomy, an acronym referring to the "seven competences of ecoefficiency" that, when adapted to the environmental strategies to support eco-efficiency, it will show the level of eco-efficiency in which companies are. We analyzed 44 (forty-four) Small business of the oil and gas production chain of Rio Grande do Norte, which works for Petrobras and are part of RedePetro RN. These companies are also part of the project "RN oil, gas and energy production chain" developed by SEBRAE-RN. We collected data from August to October 2016, using the survey method. At the end of the study it was evidenced the absence of eco-efficient Small business in the productive chain and that the best results occurred for 15.91% companies that obtained a level of "almost" eco-efficiency. The environmental strategies that promote eco-efficiency are energy efficiency, Solid Waste Management Plan (SWMP), environmental caution in supplier selection and environmental licensing. Finally, eco-efficiency is not an institutionalized management practice in the small business of this productive chain.

No. of bitstreams: 1 2012 - Rodrigo Rossi Rodrigues.pdf: 2827044 bytes, checksum: 1e0bfbc21aa38412c1823ea16ac2e2ed (MD5) Previous issue date: 2012-03-27 / The goal of this study is to show how the resource?s rationalization can improve the operational results of one maritime transport company. The tanker maket follows a world tendency on the hiring price of charter. It makes the process of costs reducing through the optimization of fuel and diesel or/and through the performance?s control of time, velocity and operational disponibility a mandatory factor. The control of the consume of fuel and diesel is a way to reduce the discounts on the ships earns. The losses can be caused by technical problems on the MCP's (Main Combustion Engine), MCA's (Auxiliary Combustion Engine) and auxiliary machinery of the ships, or by the necessity of revaluation on the contractual price of loading and unloading products on shipping terminals and also by the climate changes in the Brazilian coastline, which causes some different conditions of velocity and time trips. / Atrav?s deste trabalho pretende-se apresentar como a racionaliza??o de recursos pode contribuir para melhorar o resultado operacional de uma empresa de servi?o de transporte mar?timo. O mercado de afretamento de navios petroleiros segue uma tend?ncia mundial na contrata??o do pre?o do frete, tornando importante o processo de redu??o de custos atrav?s da otimiza??o de ?leo combust?vel e ?leo diesel, e controle das performances operacionais: tempo, velocidade e disponibilidade operacional. Uma das formas de reduzir os descontos na receita dos navios ? o controle do consumo de ?leo combust?vel e ?leo diesel. Sejam eles provocados por problemas t?cnicos nos MCP?s (Motor de Combust?o Principal), MCA?s (Motor Auxiliar de Combust?o) e M?quinas Auxiliares dos navios, ou at? mesmo pela necessidade de reavalia??o de taxas contratuais de bombeio de carga e descarga de produtos nos terminais, e velocidade/tempo de viagem em alguns trechos do litoral brasileiro, devido ?s mudan?as clim?ticas e geogr?ficas.
