摘要

According to the directive 2003/30/EC of the European Parliament and the European Council 'bioethanol fuel' means the ethanol produced from biomass and/or the biodegradable fraction of waste to be used as biofuels. The target in the EU is to significantly increase the contributions of these ecologically sustainable biofuels. Therefore a strong need to develop bioethanol production exists. In this paper bioethanol production from waste potatoes is discussed. 5-20 % of the potato crop in Finland is waste potatoes which makes them a potential feedstock for bioethanol production. In this trial the effect of ten Swedish potato cultivars on lab-scale bioethanol process was investigated. Additionally, a waste solution produced as a by-product from the distillation in a Finnish bioethanol plant was analyzed in order to improve the utilization of these by-products. Preliminary studies to develop the bioethanol distillation by simulation were performed as well. The lab-scale results indicate differences between the potato cultivars especially regarding the properties of mash and ethanol yields. The results also suggest that the utilization of waste solutions from the potato spirit plant as a fuel or a solvent could be possible. The preliminary distillation simulation studies show that azeotropic water-ethanol can be obtained by cutting the lower and higher boiling ends by conventional distillation.
