Scientists from Jaen University (Spain) have reported the use of a mathematical model from which the optimum conditions for the hydrolysis of waste from olive prunings can be made for subsequent conversion into biofuel ethanol or a value bioproduct, xylitol. The goal was to obtain the optimum time and temperature to reach maximum production. According to the researcher, Professor Alberto Moya Lopez, once the waste has been collected to particle size, the optimum hydrolysis conditions can be applied. The hydrolyzing agent attacks the hemicellulosic and cellulosic fractions of the olive pruning waste. Hemicellulose hydrolysis will produce pentosan (mainly xylose), which could be used to produce xylitol (a major "dental friendly", component in chewing gum), while the attack in the cellulosic fraction could produce glucose, which can be used to develop ethanol..
