Bioethanol, as a clean and renewable fuel with its major environmental
benefits, represents a promising biofuel today which is mostly used in
combination with gasoline. It can be produced from different kinds of
renewable feedstocks. Whereas the first generation of processes
(saccharide-based) have been well documented and are largely applied, the
second and third generation of bioethanol processes (cellulose- or
algae-based) need further research and development since bioethanol yields
are still too low to be economically viable. In this study, the possibilities
of bioethanol production from cotton fabrics as valuable cellulosic raw
material were investigated and presented. Potential lignocellulosic biomass
for bioethanol production and their characteristics, especially cotton-based
materials, were analyzed. Available lignocellulosic biomass, the production
of textile and clothing and potential for sustainable bioethanol production
in Serbia is presented. The progress possibilities are discussed in the
domain of different pretreatment methods, optimization of enzymatic
hydrolysis and different ethanol fermentation process modes.
