Mitigation of Soil Pollution by Biodegradation of Plastic Materials through Activity of Mealworms

Abstract

An excellent illustration of this idea is the use of insects in circular production systems, since they are capable of converting a variety of organic waste and byproducts into nutrient-rich feedstocks that are subsequently recycled back into the production cycle. This study reviews the use and applicability of mealworms (Tenebrio molitor) in many industries, including food, agriculture, pharmaceuticals, and more, in order to investigate their potential in circular production systems. This insect is highly versatile and has the potential to replace other sources of nutrients and other vital components, but its adoption and acceptability are currently hampered by a number of behavioral and legislative issues. The majority of plastics made from petroleum do not biodegrade in the environment. Research on the biodegradation of plastics by insects was prompted by observations of damage, penetration, and ingestion of plastics by insects and their larvae. More investigation is required to fully understand the mechanisms underlying the fast biodegradation of PS and PE. It is probable that intestinal microbial activities and the host digestive system work in concert to produce this effect. This review's primary goal is to examine insects' potential from a circular economy standpoint, with a particular emphasis on mealworm larvae. This research will also help to mitigate climate change by lowering soil contamination.
