Résumé
Four kinds of waste from the industrial processing of chestnuts (Castanea sativa), namely leaves, pruned material and burrs from chestnut tree plus chestnut shells, were characterized to determine their content in polymers and thus their potential use in biorefinery processes. Results revealed that chestnut burrs have the highest polysaccharide content being the most promising for carrying out the subsequent stages of acid hydrolysis. Treatment with diluted sulfuric acid (prehydrolysis) allowed the solubilization of xylose, glucose and arabinose, but also some toxic compounds such as furan derivatives, aliphatic acids and phenolic constituents. Xylose, the main component released in the hemicellulosic hydrolyzates, was maximized by using a 3**(2-0) full factorial design combined with desirability function. At optimum conditions set at 130 °C and 3% (w/v) H
