Using local micro-biota to extract biodegradable plastics from food waste through a natural fermentation process

Бесплатный доступ

The main problems of mankind in recent decades are the accumulation of various industrial, agricultural, and food production wastes. Their ineffective disposal and management practices have a detrimental effect on human health and cause environmental pollution, which requires urgent action. Food waste has become a complex phenomenon lately, attracting the attention of scientists, consumers, and activists. This study aims to apply the biotechnology of converting food waste into crystals of polylactic acid (PLA), a monomer for biodegradable plastic. A food waste sample is taken from the student canteen; wash, to remove impurities and fermentation of carbohydrate waste by autotrophic lactic acid bacteria in a natural process for about seven days in the optimal temperature range. Finally, lactic acid molecules polymerized by condensation reaction to form poly L-lactic acid (PLA) crystals, and then a biodegradable bioplastic.
