Abstract
Bioethanol has emerged as a viable alternative energy source in response to the growing worldwide need for sustainable energy. Largely an underutilized resource, agro-industrial waste offers bioethanol as a sustainable and affordable supply. Residues, such as agricultural leftovers, food processing by-products and lignocellulosic materials, are a substantial amount of fermentable sugars, can facilitate bioethanol production. The pre-treatment of available substrates, followed by hydrolysis to break sugars into fermentable form, fermentation to convert carbohydrates to alcohol and distillation to purify the end product, will allow rapid and sustainable production of bioethanol. Using these wastes efficiently generates eco-friendly power and helps to solve major problems with waste management and its environmental effect. Improvements in technology turning agro-waste into bioethanol mark a turning point towards a circular economy and the realisation of world energy goals.
