Abstract:
The environmental disadvantages of fossil-based fuels have necessitated some serious demands for safer and sustainable energy alternatives. Bioethanol was identified and recognized as a promising option with a sustainable choice of biofuel that was chiefly from first-generation feedstocks that threaten food security while Second generation bioethanol is produced from lignocellulosic biomass, one of the abundant renewable bio resources on earth with the adoption of active acid pretreatment to isolate the components of cellulose from hemicellulose and lignin for fermentation with the activity of enzymatic fermentation. The Paper industry has the biggest income of biomass for non-food-chain production, and, simultaneously generates a high amount of residues specifically as waste papers that are quite rich in mono- and poly-saccharides. Technically, they were utilized as a proper feedstock for second-generation bioethanol production. 100g of shredded cellulosic enzyme pretreated (2.55g initial sugar contents), acidic hydrolyzed, and saccharomyces cerevisiae fermented (72hours) waste paper samples were actively converted into 58.50% molecular sieve dehydrated ethanol. Classical characterizations (ceric ammonium nitrate & combustion tests) with GCMS -FID conditions were employed in the qualitative analysis of the generated bioethanol. This innovation reinforced the point that bio refineries must be interconnected with the technology that will be productive in the production of ethanol processing with the existing paper manufacturing plants. This will lead to added ecological advantages with product diversification and improved productivity for the pulp and paper industries.
