ClearBiodegradation of various grades of polyethylene microplastics by Tenebrio molitor and Tenebrio obscurus larvae: Effects on their physiology
Mealworm larvae (Tenebrio molitor and Tenebrio obscurus) were fed different grades of polyethylene plastic to test their ability to biodegrade this common plastic. Both species could consume and partially break down all three types of polyethylene, though the process caused oxidative stress and shifted their gut bacteria. This research suggests biological degradation of plastic waste is possible, which could help reduce the environmental breakdown of plastics into harmful microplastics.

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.
Comparison study on low-density polyethylene film biodegradation potential of Achoria grisella and Galleria mellonella larvae
This study compared the ability of two wax moth species to biodegrade low-density polyethylene plastic, finding both larvae could break down LDPE with gut microbiota playing an important role. The findings suggest potential for insect-based plastic biodegradation as a waste management approach.
Biodegradation of polyethylene, biodegradable-polyethylene bags and corn residues using Tenebrio molitor larvae
Mealworm larvae (Tenebrio molitor) were fed three plastic types — standard low-density polyethylene (LDPE), compostable plastic (CPE), and oxo-degradable plastic with d2w additives — to test biodegradation. CPE degraded most readily (up to 98% with UV pre-treatment), LDPE degraded substantially (77%), but d2w plastic degraded barely at all (4%) and killed nearly all larvae. These results challenge the environmental claims of oxo-degradable plastics and suggest they may pose toxicity risks in natural ecosystems.
Biodegradation of polylactic acid by yellow mealworms (larvae of Tenebrio molitor) via resource recovery: A sustainable approach for waste management
Researchers demonstrated that yellow mealworm larvae (Tenebrio molitor) can biodegrade polylactic acid plastic with up to 90.9% conversion efficiency on a pure PLA diet and proposed a circular waste management approach where PLA plastic serves as feedstock for insect biomass production and the resulting frass is used as fertilizer.
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.
Isolation of Plastic Digesting Microbes from the Gastrointestinal Tract of Tenebrio Molitor

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.
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 polyvinyl chloride, polystyrene, and polylactic acid microplastics in Tenebrio molitor larvae: Physiological responses
Mealworms were fed three types of microplastics (PVC, polystyrene, and PLA) and successfully biodegraded all three, but with significant physiological costs including weight loss, reduced survival, and increased oxidative stress. PVC was the hardest to degrade and caused the most harm, while biodegradable PLA was the easiest and least damaging. The study shows that biological approaches to breaking down microplastics are possible but that certain plastic types generate toxic byproducts during the process.
Can 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.
Comparison of three insect larvae biodegrading polyethylene and role of the intestinal bacterial strains in polyethylene degradation by Galleria mellonella larvae
Compared to two other insect species, Galleria mellonella waxworm larvae showed the highest polyethylene degradation ability, with gut bacterial strains identified as key contributors to plastic breakdown in a process transferable outside the host.
Identification of Biodegradable, Compostable or Toxic Plastic Bags with Two Beetles of the Tenebrionidae Family
This study used mealworm larvae (Tenebrio molitor and Zophobas morio) as a biological test to distinguish between truly biodegradable compostable bags and conventional or oxo-degradable plastic bags. Larvae could degrade compostable and standard polyethylene bags at meaningful rates but barely degraded bags made with d2w additive technology, and the d2w bags caused 98% larval mortality — suggesting they contain toxic compounds. The results raise concerns about the safety and environmental claims of certain marketed "eco" plastic alternatives.
