TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.

TL;DR: Quadratic models using time, temperature, and concentration as continuous variables were developed to predict xylan and lignin reduction, respectively for sulfuric acid and sodium hydroxide pretreatments, and explained most of the variation in xylan or lign in reduction through simple linear regressions.

TL;DR: The high chemical consumption for alkaline pretreatment technology indicates that the main challenge for commercialization is chemical recovery, however, repurposing or co-locating a biorefinery with a paper mill would be advantageous from an economic point of view.

TL;DR: Production of bioethanol from agricultural residues and hays through a series of chemical pretreatment, enzymatic hydrolysis, and fermentation processes was investigated in this study, indicating that concentration and treatment agent play a significant role during pretreatment.

TL;DR: Ensiling of barley, triticale, wheat straws, and cotton stalk significantly increased the conversion of holocellulose to sugars during subsequent hydrolysis with two enzyme combinations, and saccharification with Celluclast 1.5 L-Novozyme 188 resulted in equal or higher saccharisation than with Spezyme® CP–xylanase combination.
