Aspects Regarding the Economic Study of the Bioethanol obtained by Development of a New Environmentally Friendly Pretreated Method

摘要

Due to the fact that lignocelluosic biomass is an inexhaustible source of energy, the range of raw materials used for obtaining bioethanol is extremely wide and abundant: agricultural and forestry wastes, used paper or municipal wastes. For producing bioethanol from lignocelluosic biomass, a process of the carbohydrates chemical or enzymatic cleavage (hydrolysis) and fermentation is necessary, with the use of microorganisms. The goal of this paper is to explore the pretreatment process of the UgnocelMosk substrate in order to facilitate the enzymatic biodegradation. The process is characterized by efficiency and ingenuity because the pretreated biomass assures the increase of enzymatic hydrolysis yield and, in the same time, allows comparable fractionation yields for all biomass types by comparison with the known pretreatment methods. Cost-benefit analysis is a method used for evaluating a policy which quantifies in monetary terms the value of all the consequences of this policy on all society members. More specifically, the objective of cost-benefit analysis is to facilitate a more efficient allocation of resources.
