TECHNICAL-ECONOMIC PROPOSAL TO IMPROVE PRODUCTION AND MARKETING Bacillus BIOPESTICIDES thuringiensts DE PLANT Biologies KILLS

Abstract

In this investigation techno - economic alternatives that facilitate the commercialization of the Bacillus thuringiensis pesticide are valued, that is obtained in the biochemical Plant in Matanzas. One selects the sedimentation, filtration and centrifugation as mechanical separations mechanisms for the elimination the water content whereupon the Bacillus thuringiensis takes place. In order to select the most suitable mechanism heuristic methods directed are applied to the operational and economic analysis of the operations. The operational analysis includes the characterization of the product and an optimization of the separation process in which the more suitable raw material for the production of the pesticide and the influence of the parameters studied in the quality of the product and the separation of phases is defined. The economic analysis allows to complement the results of the technical analysis when defining to the feasible alternative sedimentation after obtaining a positive Net Present Value (NPV) for this operation, contrary to the obtained ones with the remaining studied mechanisms.
