Abstract

Synthetic plastics derived from petroleum have a substantial share in the packaging industry and related sectors, due to their special properties in meeting the needs of various industries. As a result, the demand for these plastics is constantly increasing. Despite the advantages and wide applications of synthetic plastics, their non-biodegradability poses a serious threat to humans and animals, especially marine species. Additionally, their continuous production leads to a decrease in petroleum reserves and a significant increase in carbon dioxide emissions. On the other hand, the continuous release of waste from the food processing industry into nature has adverse environmental impacts, due to the large number of organic compounds. Since these wastes contain significant amounts of biodegradable polymers or their precursors, they can be considered suitable sources for the production of bioplastics. Such a substitution can potentially reduce the environmental impacts and economic effects of conventional plastics and food waste. In this article, synthetic plastics are first reviewed, and then studies on the conversion of food waste into bioplastics and the advantages and disadvantages of each are reviewed.
