Análisis de Ciclo de Vida para la producción de biodiesel en comunidades agrícolas cubanas. Inventarios

Abstract

Diverse tools of evaluation of the significant environmental impacts exist, associated to any productive activity or services, but in the majority cases they are qualitative and they do not express with its results all the necessary information, to be able to drive suitably, but the life cycle assessment (LCA), it studies the environmental aspects and it allows to evaluate the associate environmental loads throughout the cycle of life of a product, in this case, the production of biodiesel in Cuba from the energy inventories, raw materials, products and emissions to enviroment, using two sources that do not contradict the state policy, that is not to change
foods by fuels, and these sources are: cachaza, like sugar bowl wastes and the seeds of the Jatrophas Curcas L., of that it is extracted a toxic oil and both they have as advantages that by-products and activities have stops economic, environmental and social high values, that gives important credits to the proposal. This tool includes the stages of extraction and processing of raw materials, manufactures, transport, distribution, use, reusability and maintenance; recyclingand final destinyof the waste fraction, reason whythe initial work is to define the objectives and scopes of study, soon to do a deep inventoryof the processes (extension of this work),
it will allow the pass of the evaluation of impacts and the improvements that arise to demonstrate how environmentally are compatible or not, in the obtaining of biodiesel in the present economic, environmental and social conditions of Cuba.
