Simple physicochemical pretreatments for agrofood wastes
The selected agro-food wastes (potato peel, apple pomace, brewers’ spent grain and coffee silverskin) contain 8-21% cellulose, 7-19% hemicellulose and 19-33% lignin. In order to use these agro-food wastes as feedstocks for butanol biorefineries, simple sugars must be released from cellulose and hemicellulose. In the Waste2Fuels project, ITACyL has focused on physicochemical pretreatments to degrade…

Butanol production from agrofood wastes is possible
Biobutanol can be obtained by sugar fermentation. One of the main objectives of Waste2Fuels is the development of suitable pretreatments for lignocellulosic biomass, in order to release simple sugars from cellulose and hemicellulose, thus obtaining fermentable streams for biobutanol production. Apple pomace, a waste from juice and cider industries, has been successfully employed for biobutanol…
