Bioconversion of Starch Base Food Waste into Bioethanol

The global demand for fuel keeps increasing daily. The massive depletion of fossil fuels and their influence on the environment as pollution is a severe problem. Meanwhile, food waste disposal is also a complex problem in solid-waste management since one-third of every food consumed is discarded as waste. The standard waste management methods, including food waste incineration and landfilling, are considered hazardous to the environment. Food waste constituents are majorly starch-based and contain various biomolecules, including sugar, lipids, proteins, vitamins, cellulose, etc. These polysaccharides can be hydrolysed into monosaccharides such as glucose, which can then be fermented using microorganisms to produce ethanol through the fermenting of sugars derived from enzymatic hydrolysis treatment of food wastes. The human food system is rich in starch, which can be a potential resource for bioethanol production.

Automated summary

The global demand for fuel is increasing daily, while the depletion of fossil fuels and their environmental impact as pollution is a severe problem. Food waste disposal is also a complex issue, with current management methods considered hazardous. However, the starch found in food waste can potentially be converted into ethanol through fermentation, making it a valuable resource for bioethanol production.
