The Production of Alcohol from Municipal Waste(I) -The Changes of Components of the Pretreated Lignocellulosic Biomass-

도시 폐기물로부터 알콜생산(I) - 전처리된 lignocellulosic biomass의 조성분 변화 -

In recent years, the municipal wastes recognized resources. This study was performed to survey the changes of main components of the pretreated(chemical, physical) lignocellulosic biomass. The result can be summerized as follows; In pulp fiber composition, newsprint and corrugating container were mainly consist of softwood fiber(tracheid). But computer print out and magazine had a large amount of hardwood fiber(wood fiber). And, carbohydrate content in the various lignocellulosic biomass increases as the following orders : Magazine < Newsprint < Corrugating container < Computer print out. In the chemical pretreatments for the delignification, sodium hypochlorite pretreatment was more effective than sodium hydroxide. By washing, ash content of lignocellulosic biomass was decreased. Physical pretreatments were less effective than chemical pretreatment for the delignification. On the other hand, in physical pretreatments, ash content of lignocellulosic biomass was the same tendency as in the chemical pretreatments.
