Agricultural Waste Utilization forthe Production of Alcohol- A Review

Abstract

Waste is any substance that is discarded as worthless, defective, and of no use. Agriculture waste, Domestic waste, Industrial waste, and commercial waste are the types of waste. Agricultural waste is unwanted or unsalable material, cheaply available, and has the potential to produce energy that occurs during harvesting and processing. The agriculture and industry-based waste produced during the growing and processing of raw materials like cereals, fruits, vegetables, meat, fish, and poultry are the residues. Including rice bran, wheat bran, wheat straw, sugar cane bagasse, and sugar cane molasses. Produced waste from agriculture has a good potential to convert into energy and is also rich in some residue like cellulose, lignocellulose, and hemicellulose. As for alcohol production sugar or starches are required but with the use of recent technologies developed by scientists can produce lignocellulosic waste. Various pre-treatment methods were developed by scientists for alcohol production. Presence of residue and good potential the waste can be utilized for various products like alcohol production, methane production, organic chemicals, biofuels, biogas, enzymes, vitamins, antioxidants, fermented products by solid-state fermentation, and animal feed. The following paper concerns the studies
made on agriculture waste utilization and different types of pre-treatment methods used for accelerating yield of the alcohol production.
