To provide a system for efficiently using a lignocellulose, which organically combines three processes of an ethanol fermentation process, a kraft process and a sulfite process and make them cooperatively act by putting them to combined use.
The system for exceedingly efficiently producing bioethanol etc., includes a kraft cooker for kraft cooking a first lignocellulose raw material to give kraft pulp and kraft black liquor, a sulfite cooker for sulfite cooling a second lignocellulose raw material on a sodium base to give sulfite pulp and sulfite black liquor, an ethanol fermenter for ethanol fermenting sulfite black liquor to give ethanol and fermented liquor and a cooking chemical recovery apparatus for recovering cooking chemicals contained in the graft black liquor and the fermented liquor and sending the recovered cooking chemicals to the kraft cooker.
