ClearCan the insects Galleria mellonella and Tenebrio molitor be the future of plastic biodegradation?
This review examines recent discoveries about how wax moth and mealworm larvae can break down common plastics using enzymes in their saliva and gut microorganisms. Researchers found that these insects offer a promising biological alternative to traditional plastic disposal methods like landfilling and incineration, which themselves contribute to microplastic pollution. The study highlights key challenges including the need for standardized testing methods and proposes innovative ideas like using insects as living bioreactors for plastic waste processing.
Using Insect Larvae and Their Microbiota for Plastic Degradation
This review summarizes research on insect larvae, including wax worms and mealworms, that can eat and break down plastic using bacteria and enzymes in their guts. Recent discoveries include novel plastic-degrading enzymes found in wax worm saliva that can begin breaking down polyethylene within hours. While still far from a large-scale solution, this biological approach to plastic degradation could eventually help reduce the microplastic pollution that threatens ecosystems and human health.
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.
The use of insects, some land and marine invertebrates, in the biodegradation of plastic
This review examines the potential of insects and invertebrates—including mealworms, wax moths, and shipworms—to biodegrade plastics, microplastics, and nanoplastics, summarizing the gut microbiomes and enzymes involved and the prospects for practical bioremediation.

Unveiling Fragmentation of Plastic Particles during Biodegradation of Polystyrene and Polyethylene Foams in Mealworms: Highly Sensitive Detection and Digestive Modeling Prediction
Researchers discovered that mealworms biodegrading polystyrene and polyethylene foams generate micro- and nanoplastic fragments during the digestion process, despite removing over 70% of the ingested plastic. The study developed a digestive biofragmentation model to predict plastic fragmentation patterns, suggesting that insect-based plastic biodegradation may create secondary contamination that warrants further assessment.
Mitigation of Soil Pollution by Biodegradation of Plastic Materials through Activity of Mealworms
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.
Technological application potential of polyethylene and polystyrene biodegradation by macro-organisms such as mealworms and wax moth larvae
Researchers tested polyethylene biodegradation by mealworms and wax moth larvae across multiple experimental setups, finding that while live larvae altered LDPE surface morphology, homogenized larval paste produced no detectable mass loss or ethylene glycol, suggesting a mechanism beyond gut microbiome action alone. Techno-economic and life cycle assessment analysis indicated that scaling this process as a plastic waste management technology is currently not feasible.
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.
Isolation of Plastic Digesting Microbes from the Gastrointestinal Tract of Tenebrio Molitor
Researchers isolated bacteria from the gut of Tenebrio molitor mealworm larvae that are capable of degrading polystyrene and polyethylene microplastics. The identified gut microbes showed plastic-degrading enzymatic activity, suggesting potential for bioremediation applications.
Biodegradation of Polystyrene by Plastic-Eating Tenebrionidae Larvae
Researchers tested the ability of mealworm (Tenebrio molitor) and superworm (Zophobas morio) larvae to biodegrade polystyrene foam through feeding experiments with different dietary conditions. They found that both species could consume and break down polystyrene, with gut microorganisms playing a key role in the degradation process. The study suggests that insect-based biodegradation could offer a biological approach to addressing polystyrene waste in the environment.
Gut Microbiome and Degradation Product Formation during Biodegradation of Expanded Polystyrene by Mealworm Larvae under Different Feeding Strategies
Researchers found that mealworm larvae successfully degrade polystyrene under different feeding strategies, with gut microbiome composition and degradation byproduct profiles varying by diet, demonstrating that diet manipulation can optimize the biological plastic-degradation capacity of the mealworm system.

This review examined the mechanisms by which bacteria, fungi, and insect larvae break down plastic waste, covering different enzymatic strategies used by each type of organism. Biological plastic degradation offers a low-cost, environmentally friendly approach to addressing 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.
Entomoremediation: An ecofriendly approach for waste management: A review

Some insect larvae have shown ability to ingest and partially break down plastics, offering a low-cost biological waste processing option.
Environmental Biotechnology: Biodegradation of Microplastics with Larvae of Tenebrio Molitor and Galleria Mellonella
Researchers tested the ability of mealworm (Tenebrio molitor) and wax moth (Galleria mellonella) larvae to biodegrade microplastics collected from a Peruvian beach, finding that both species could partially degrade plastic samples, supporting insect larvae as a promising biotechnology for microplastic remediation.
Insect farming: A bioeconomy-based opportunity to revalorize plastic wastes
Researchers propose a two-step system for managing plastic waste using insects. First, mealworm larvae partially break down plastics like polystyrene and polyethylene, and their microplastic-containing waste is then converted into biochar through high-heat treatment. The biochar is then used to enrich compost processed by black soldier fly larvae, creating a nutrient-rich soil amendment while addressing both plastic waste and organic waste in a circular approach.
Feeding and metabolism effects of three common microplastics on Tenebrio molitor L.
