Главной проблемой человечества в последние десятилетия является накопление различных отходов промышленности, сельского хозяйства и производства продуктов питания. Их неэффективная утилизация и практика управления оказывают пагубное влияние на здоровье человека и вызывают загрязнение окружающей среды, что требует принятия срочных мер. В последнее время пищевые отходы стали сложным явлением, привлекающим внимание ученых, потребителей и активистов. Целью данного исследования является применение биотехнологии преобразования пищевых отходов в кристаллы полимолочной кислоты (PLA), мономера для биоразлагаемого пластика. Образец пищевых отходов берется из студенческой столовой; промывается для удаления примесей и ферментации углеводных отходов автотрофными молочнокислыми бактериями в естественном процессе в течение примерно семи дней в оптимальном диапазоне температур. Наконец, молекулы молочной кислоты полимеризуются по реакции конденсации, образуя кристаллы поли-L-молочной кислоты (PLA), а затем биоразлагаемый биопластик.

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.
