摘要： Cotton-containing textiles, such as “trash” feedstock in terms of end-of-life-cotton textiles, may be used to produce sugar without the same kinds of harsh pretreatments used for other biomasses, such as corn, grass sources, or wood. Disclosed is a process for production of sugar from a cotton-containing textile waste fabric comprising optionally mechanically pretreating the cotton-containing textile, pretreating the cotton-containing textile with an acid pretreatment to form a slurry, cooling the slurry, adding at least one base to the slurry, adding at least one additional acid to the slurry to form a buffer in situ, adding a hydrolysis enzyme, and optionally filtering the slurry.
