Abstract
- Environmental issues such as the depletion of non-renewable energy resources and pollution are topical. The extent of solid waste production is of global concern and development of its bioenergy potential can combine issues such as pollution control and bioproduct development, simultaneously. Various wastepaper materials, a major component of solid waste, were treated with the cellulase enzyme from Trichoderma viride, thus bioconverting their cellulose component into fermentable sugars. All wastepaper materials exhibited different susceptibilities towards the cellulase as well as the production of non-similar sugar releasing patterns when increasing amounts of paper were treated with a fixed enzyme concentration. The hydrolysis of wastepaper with changing enzyme concentrations and incubation periods also resulted in dissimilar sugar-producing tendencies. A general decline in hydrolytic efficiency was observed when increasing sugar concentrations were produced during biodegradation of all wastepaper materials.
