Abstract:
The aim of this study was to examine the possibility of using pretreated cellulosic medical waste as a remarkable source of glucose production and maximize enzymatic digestibility efficiency of cellulose. The pretreatment approach that was used to enhance medical paper waste enzymatic digestibility was sequential acid and enzymatic hydrolysis. The independent variables of the acid hydrolysis pretreatment conditions were time, temperature, and concentration of dilute acid solution. Diluted sulfuric acid was chosen as the treatment solution. The acid hydrolysis temperature was 180, 200 and 220 oC, the acid concentration was 0.01, 0.0225 and 0.035 M and the isothermal reaction time was 0, 20 and 40 min. The combinations of the experimental conditions were depicted by using Stat-Ease 360, the latest-release of Design-Expert® software. These condition sets operated simultaneously for cellulose enzymatic digestibility optimization, as well as a sterilization procedure for the medical paper waste which contains many harmful and toxic substances for humans. The product of acid hydrolysis process was separated in solid cellulosic phase and liquid glucose containing phase. The solid product of acid hydrolysis was studied as a recycled sterilized material for fermentable to ethanol glucose production via enzymatic hydrolysis.
