O progresso desordenado, provocado pelo adensamento demográfico, tem gerado problemas, quando embasado nos padrões do paradigma capitalista. Isso faz prever mudanças na gestão empresarial, para adequar-se a um novo modelo, com a inserção dos conceitos de Produção limpa (PL), Mais Limpa (P+L), Enxuta (PE) e Manutenção Produtiva Total (MPT). A MPT visa obter a máxima eficiência do sistema produtivo, identificando os possíveis desperdícios que possam ocorrer, bem como sua prevenção. Aliada à Produção limpa e Enxuta (PLE), que propõe um planejamento ambiental, como forma de eliminar qualquer forma de desperdício com a melhoria dos processos, a MPT pode fazer com que a economia se fortaleça juntamente com a melhoria da produtividade, gerando melhorias no desenvolvimento social, rumo ao desenvolvimento sustentável. A sustentabilidade ambiental deve ser promovida com a conservação da diversidade biológica, com o uso sustentável de seus componentes, com uma distribuição justa e eqüitativa dos benefícios advindos da utilização racional dos recursos disponíveis. O foco principal deste trabalho foi elaborar uma metodologia que possibilitou garantir a confiabilidade nos sistemas hidráulicos das colhedoras de cana-de-açúcar, identificando e analisando os modos de falhas, de modo a resultar, numa melhoria da qualidade ambiental e sócio-econômica no ambiente de uma indústria sucroalcoleira por meio da diminuição significativa de derramamento de óleo hidráulico. O trabalho teve como base a análise de um estudo envolvendo os princípios da Produção limpa e Enxuta, a partir de critérios para avaliação de modos de falhas que provocam vazamentos no sistema hidráulico das colhedoras, visando à melhoria contínua da Manutenção Produtiva Total. Por meio do histórico existente no ERP (Enterprise Resource Planning), utilizado em uma Usina sucroalcoleira, foi possível fazer o acompanhamento do desempenho operacional de colhedoras de cana-de-açúcar, utilizadas durante 03 safras, com relação aos modos de falhas no sistema hidráulico das mesmas, sendo que, em uma das safras foi elaborado e efetuado um controle total do sistema hidráulico de 5 colhedoras. Os dados obtidos e a metodologia desenvolvida permitiram apontar indicadores de sustentabilidade desejados para a situação estudada, com os quais foi possível desenvolver um software especifico para tomada de decisões / Abstract: Among the important changes in the production processes, it is the need to guarantee the sustainability of the human enterprises. The disordered progress, provoked by the demographic agglomeration, it has been generating problems, when based in the patterns of the capitalist paradigm. That makes to foresee changes in the managerial administration, to adapt to a new model, with the insert of the concepts of clean production (PL), more it Cleans (P+L), Dried (FOOT) and Total Productive Maintenance (TPM). TPM seeks to obtain the maxim efficiency of the productive system, identifying the possible losses that can happen, as well as your prevention. Allied to the clean Production and Dried (PLE), that proposes an environmental planning, as form of eliminating any waste form with the improvement of the processes, TPM can do with that the economy strengthens together with the improvement of the productivity, generating improvements in the social development, and heading for the maintainable development. The environmental sustainability should be promoted with the conservation of the biological diversity, with the maintainable use of your components, with a fair and equal distribution of the occurring benefits of the rational use of the available resources. The main focus of this work was to elaborate a methodology that made possible to guarantee the reliability in the waterworks of the harvester sugar-cane, identifying and analyzing the manners of flaws, in way to result, in an improvement of the environmental and socioeconomic quality in the atmosphere of an industry of sugar-cane through the significant decrease of spill of hydraulic oil. The work had as base the analysis of a study involving the beginnings of the Production it cleans and Dry, starting from criteria for evaluation of manners of flaws that they provoke leaks in the waterworks of the harvesters, seeking to the continuous improvement of the Total Productive Maintenance. Through the existent report in ERP (Enterprise Resource Planning), used in a Sugar-cane Industry Plant, it was possible to do the accompaniment of the operational acting of sugar-cane harvester, used during 03 crops, with relationship to the manners of flaws in the waterworks of the same ones, and, in one of the crops it was elaborated and made a total control of the waterworks of 5 harvesters. The obtained data and the developed methodology allowed to point sustainability indicators wanted for the studied situatiith which it was possible to develop software I specify for electric outlet of decisions / Doutorado / Planejamento e Desenvolvimento Rural Sustentável / Doutor em Engenharia Agrícola

Content: With the development of China sports, researches related to sports leather should be paid attention because they usually required higher strength than commonly used leather. In this paper, we focus on the production of gymnastics leather. In gymnastics, the athlete's hand will have high intensity contact with the balance bar, so the gymnastics leather is required to have high intensity performance. At the same time, in order to comply with the ornamental function, gymnastics leather is required to be light color. In this research, glutaraldehyde was used as the main tanning agent, while acrylic polymer and synthetic were used for retanning, in order to obtain high strength, environmentally friendly white gym leather. The shrinkage temperature and mechanical properties of tanned leather were determined and analyzed to determine the suitable tanning agent. Besides, other properties including softness, gas permeability, water permeability, flexing resistance and yellowing-resistance were also measured for selecting proper production process. Therefore, gymnastics leather with ideal performance can be prepared by this method, and the leather conforms to the practical application standard. In addition, the research has guiding significance and application prospect for high strength chrome-free tanned leather. Take-Away: Aldehyde tanning agents and retanning agents, which can be used for gymnastics leather making, were evaluated and selected to achieve ideal effect of finish leather. This research is meaningful to produce not only gymnastics leather but also other sporty leather which require high strength.

An unit for treat produced waters called UTMDIF, was designed, installed and operated in an industrial plant for treatment of effluents from oil industry. This unit operates by means of the method of separation of phase inversion and can become a promising alternative to solve the problem of oil/water separation. This method constitutes the basis of the working of a new design of mixersettler of vertical configuration which occupies small surface area. The last characteristic becomes specially important when there is limitation on the lay-out of the plant, for example, over maritime platforms to explore oil. This equipment in a semi-industrial scale treats produced wastewaters contaminated with oil at low concentrations (ranging from 30 to 150 mg/L) and throughputs of 320 m3/d (47,4 m3 m-2 h-1). Good results were obtained in oil/water separation which leads to the necessary specification to discharge those wastewaters. Besides, the non dependence of the efficiency of separation in spite of the salinity of the medium becomes the equipment an attractive new technology to treat wastewaters containing oil at low concentrations / Este trabalho tem por objetivo utilizar uma nova tecnologia no tratamento de ?guas produzidas da ind?stria do petr?leo. Uma Unidade de Tratamento de ?guas Produzidas, denominada UT-MDIF, foi projetada, instalada e operou dentro de uma planta industrial de tratamento de efluentes de petr?leo. Esta Unidade de Tratamento piloto utiliza o m?todo de separa??o ? invers?o de fases e pode se tornar numa alternativa promissora para resolver o problema de separa??o ?leo/?gua. Este m?todo constitui a base do funcionamento de um novo modelo de misturador-decantador de configura??o vertical e que ocupa pequena ?rea superficial. Esta ?ltima caracter?stica se torna especialmente importante, quando existe limita??o de espa?o no lay-out da planta industrial, por exemplo, uma plataforma mar?tima para explora??o de petr?leo. Este equipamento em escala semi-industrial trata ?guas produzidas contaminadas com petr?leo em baixas concentra??es da ordem de 30 a 150 mg/L e vaz?es efetivas de 320 m3/d (47,4m3m-2h-1). Os bons resultados na separa??o ?leo/?gua, obtendo-se a especifica??o necess?ria para descarte, associado ? n?o depend?ncia da efici?ncia de separa??o face ? salinidade do meio, podem tornar o equipamento uma nova tecnologia no tratamento de ?guas contaminadas com ?leo a baixas concentra??es
