Revolutionizing Plastic Waste Management: A Bibliometric Analysis of Superworm and Mealworm Biodegradation Potential
AI summary Read the abstract
Researchers conducted a bibliometric analysis of studies on superworms (Zophobas morio) and mealworms (Tenebrio molitor) as plastic biodegradation agents, finding rapid growth in publications from 2019–2024 and highlighting these insects' enzymatic potential as eco-friendly alternatives to conventional plastic waste management.
The rapid increase in plastic use has contributed to a 12% accumulation of plastic waste, ranking it as the fourth largest global waste category. Conventional degradation methods remain largely ineffective, prompting interest in biological alternatives. Recent studies highlight superworms (Zophobas morio) and mealworms (Tenebrio molitor) as potential agents for plastic biodegradation. This study applies bibliometric analysis using ProQuest data from 2019–2024. The co-occurrence keyword analysis identified 53 keywords, 940 links, and a total link strength of 2521. Publications rose from 2 in 2019 to a peak of 8 in 2023, with 6 already in 2024. Polymers emerged as the leading journal (9 papers). China was the most active country, followed by Poland, Japan, Malaysia, Spain, and Italy. Common keywords associated with T. molitor and Z. morio were “insect,” “larva,” and “protein,” reflecting the focus on biological and nutritional aspects. Findings underscore the potential of superworms and mealworms in reducing plastic waste through biodegradation. They also open avenues for further research into enzymes, nutrients, and consumption, emphasizing the link between nutrition and enzymatic efficiency. Continued study is essential to deepen understanding and maximize the role of these insects in addressing global plastic waste.

AI summary Read the abstract
This comprehensive review identifies over 23 insect species across multiple orders capable of degrading plastic polymers, proposing that plastic-degrading enzymes are likely evolutionary repurposings of enzymes originally used to digest natural materials like lignin, beeswax, and chitin—insights that could inform engineering of robust enzymes for large-scale plastic bioremediation.
Global research landscape of microplastics and their impact on earthworm: a bibliometric analysis
AI summary Read the abstract
Researchers conducted a bibliometric analysis — a statistical review of published research — to map global trends in studies on how microplastics affect earthworms, finding steady growth in publications through 2022 with China and Europe leading the research. Earthworms are a key focus because they live in soil, help decompose organic matter, and serve as an indicator species for measuring how microplastics disrupt soil health.
Worming the Circular Economy for Biowaste and Plastics: Hermetia illucens, Tenebrio Molitor and Zophobas morio
AI summary Read the abstract
This paper examines whether insect larvae — black soldier flies, mealworms, and superworms — can help process both organic food waste and plastics as part of a circular economy. COVID-19 increased single-use plastic waste and food waste simultaneously, making combined bioconversion solutions appealing. The authors review evidence for using these insects to reduce two major waste streams at once.
Mealworms are plastic waste disposers

This conference paper highlights recent research demonstrating that mealworms can consume and biodegrade plastic waste, presenting the insects as a promising biological tool for addressing plastic pollution across ecology, chemistry, and earth sciences disciplines.
Integrative frameworks for plastic biodegradation in insect–microbiome systems: mechanistic insights, emerging multi-omics and enzyme engineering perspectives
AI summary Read the abstract
Certain insect larvae (like mealworms) can chew up and break down plastic with help from bacteria living in their guts, offering a possible natural solution to our massive plastic waste problem. This review pulls together what scientists currently know about how this works — a team effort between the insect's own body and its gut microbes — though it's still unclear exactly how much the plastic is being fully broken down versus just partially altered. The bigger payoff: understanding these natural processes could help researchers engineer better enzymes to break down plastic waste at scale, which matters because plastic pollution and the microplastics it creates are increasingly showing up in our food, water
