Economic evaluation of enzymic utilisation of waste cellulosic materials

Abstract

This paper deals with a review of the methods available for utilisation of waste cellulosic materials and gives a brief description of the process developed for enzymic saccharification of cellulose. For economic evaluation of the process, a cost estimate has been drawn up after a careful analysis of the cost elements involved in the production of glucose. A similar cost‐structure based on the process for the production of SCP from waste newspaper is also presented. The estimated price of glucose or biomass from this source appears to be compatible with the reported market price of these products.

“…24,25 The conversion of cellobiose into glucose is a ratelimiting step since high concentrations of cellobiose can inhibit cellobiose production. [26][27][28][29] Trichoderma reesei cellulase is the most commonly used industrial cellulase 19 and has very low amounts of b-glucosidase. 30 Previous work in the literature has found that supplementing the reaction with additional b-glucosidase can reduce cellobiose inhibition and substantially increase glucose yields.…”
