Mitigation of Soil Pollution by Biodegradation of Plastic Materials through Activity of Mealworms
Summary
This review examines how mealworms (Tenebrio molitor) can biodegrade plastics including polystyrene and polyethylene, and discusses their use in circular production systems. Insect-based plastic biodegradation represents a promising biological approach to reducing plastic waste before it fragments into microplastics in the environment.
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.

Biodegradation of Different Types of Plastics by Tenebrio molitor Insect
This study reviewed the potential of mealworm beetle larvae (Tenebrio molitor) to biodegrade multiple plastic types through gut microbiota activity, finding that the larvae could break down various polymers including polystyrene and polyethylene, making entomoremediation a promising avenue for plastic waste reduction.
Feeding and metabolism effects of three common microplastics on Tenebrio molitor L.
Mealworm larvae from three Chinese regions were fed microplastics (polystyrene, PVC, and LDPE) and were found to actually break down some of the plastic in their gut. The ability of mealworms to partially degrade certain plastics makes them a potential tool for biological plastic waste management.
Plastic Biodegradation through Insects and their Symbionts Microbes: A Review
This review examines how insects and their gut microbes can break down plastic waste, covering species like mealworms and waxworms that can digest polyethylene and polystyrene. The bacteria living in insect guts are responsible for much of this plastic-degrading activity. Insect-based biodegradation could offer a scalable biological solution to reducing plastic pollution.
Biodegradation of aged polyethylene (PE) and polystyrene (PS) microplastics by yellow mealworms (Tenebrio molitor larvae)
Yellow mealworm larvae were able to consume and biodegrade both fresh and aged polyethylene film and polystyrene foam over a 35-day period. While aged plastics slightly slowed larval growth, the worms still broke down the plastic with help from their gut bacteria, confirmed by chemical analysis showing structural changes in the consumed plastic. This biological approach to plastic degradation could help reduce the amount of plastic waste that eventually breaks down into microplastics in the environment.
Biodegradation of Post-Consumer Expanded Polystyrene and Low-Density Polyethylene by Tenebrio molitor Larvae
Scientists found that mealworms (beetle larvae) can actually break down used plastic bags and foam containers by eating them and changing their chemical structure. The mealworms produce waste that contains smaller plastic pieces and chemical compounds, which could potentially reduce plastic pollution in the environment. This research is important because it shows a natural way to help deal with the massive amounts of plastic waste that currently pile up in landfills and oceans.
