Techno-Economic Aspects of Ethanol Production from Lignocellulosic Agricultural Crops and Residues

Forskningsoutput: Kapitel i bok/rapport/Conference proceedingKapitel samlingsverk


Bioethanol has been introduced on a large scale in several countries, for example, in Brazil, the United States, and some European countries such as Sweden. Currently, most bioethanol is produced using starch- or sugar-based production from wheat, corn, or sugar cane (first-generation bioethanol). However, to be able to meet the expected demand, further expansion will have to come from lignocellulosic materials, for example, forest or agricultural residues. Research and development are currently intense, but, so far, no full-scale plant is put in operation. Techno-economic estimations are therefore based on experimental work performed in either lab scale or pilot scale. In this article, technical and economic aspects on the current status of the biomass-to-ethanol conversion are discussed, with regard to some of the more important steps in a process, for example, pretreatment, hydrolysis, and fermentation. Also, the importance of integration with existing plants, such as combined heat and power plants, and with already-running first-generation bioethanol plants is discussed.
