In the paper are exposed the possibilities of achieving a clean technology of production of corrugated paper from the employment of the pounding of the trash of sugar cane with ethanol. Were established the possibilities of achieving, by means of an analysis, processes of material and energy integration of the manufacture of sugar and installations of production of by-products. These processes are technologically and energetically sustainable, environmentally compatible, and economically competitive based in the benefits that can be achieved through the material and energy integration of the sugar cane by-products and the possibility of producing celluloid pulps with ethanol for corrugated cardboard, and by-products from the lignin obtained in the process.

The aim of this paper is to assess the current operating and safety conditions of biological treatment systems for wastewater in the centers of swinish and poultry breeding at Villa Clara Water Management Company, with the purpose of setting a group of organizational, technical and human measures that contributes to prevent contamination and minimize biological risks. In this way it can be guaranteed the protection to the workers, the facilities, community and the environment, to have a sure occupational atmosphere in the organization. As a result of the evaluation the factors that affect the operation of the biodigestion system and the security of the process are defined. [ABSTRACT FROM AUTHOR]

In this paper the use of the Integrated Management Systems in the Cuban sugar production is analyzed. Coherently to the strategic management process that takes place in the Cuban sugar industry, an initial conceptualization of these systems and an evaluation of their utility for any organization are performed. Finally, some recommendations for applying the integrated management systems approach in this business context are provided. [ABSTRACT FROM AUTHOR]

Main economic and environmental aspects of cogeneration technologies for the energy sector of sugar cane industry are considered in this paper. Special emphasis has been made about the aspects of the fuel cycle affecting environmental performance of these technologies. An assessment is done to show the potential of sugar cane biomass in the context of the Cuban energy sector. [ABSTRACT FROM AUTHOR]

In this paper we study the impact of new substrates on the production of Torula yeast in Cuba, by analyzing combinations of mixtures of juice of the clarified filters, still wines, and final honey, according with its yield: % of gross protein, substrates costs and protection of the environment, measured as Chemical Oxygen Demand. For that, it was carried out a study at laboratory scale, by means of an experiment simple mesh-type, being obtained the models that correlate yield in propagation, gross protein and chemical oxygen demand in function of the contribution total sugar reducers for each substrate. The results showed the feasibility of production of Torula yeast with substrates mixtures, for the optimum proportions of mixture honey-juice-wines of 58, 12 and 30% of contribution of ART respectively, for a prospective yield of 42%, and in binary mixture honey-wines: 40-60 % for 39 % yield .
