Accelerated electrons dislodge cellulosic sugars from lignocellulosic feedstock [Registered]

Extracting cellulosic sugars from lignocellulosic biomass is costly as it is difficult to tease out the cellulose and hemiceullose fractions from the recalcitrant lignin and hydrolyse the former two into sugars which could then be used through the conventional route to produce biofuels via fermentation. The US-based start-up Xyleco has developed a process that is currently being scaled up for obtaining sugars from crop residues employs beams of accelerated electrons to fracture chains of cellulose and hemicellulose, allowing dramatically improved enzymatic hydrolysis in subsequent process steps. The company is building a commercial-scale demonstration plant in Moses Lake, Washington to make…
