Biodegradation of Single Use Plastic Waste by Insect Larvae: A Comparative Study of Yellow Mealworms and Superworms

Gino Apollo Marajas Guerrero, Michelle Solleza Guerrero

Abstract


The global plastic waste crisis, worsened by ineffective recycling and environmental pollution, necessitates exploration of alternative disposal methods. This paper examines the biodegradation capabilities of yellow mealworms, Tenebrio molitor and superworms, Zophabas atratus, focusing on their consumption of expanded polystyrene (EPS), low-density polyethylene (LDPE), and biodegradable plastics. Plastic waste, mainly composed of non-hydrolyzable plastics like polyethylene and polystyrene, presents challenges due to slow degradation. The research reveals the larvae's preference for EPS, highlighting the importance of species-specific considerations in plastic waste management. Preference for EPS is crucial because it is bulkier and more difficult to dispose compared to other types of plastics. Experimental setups monitored larval consumption, with weight measurements and frass production indicating preferences. Fourier-transform infrared spectroscopy confirms signs of biodegradation in the frass, demonstrating the transformative impact of larval digestion on plastic structures. Despite valuable insights, challenges like maintaining larval nutrition and understanding environmental factors' influence on degradation efficiency require further exploration. Utilizing insect larvae for plastic waste management holds promise for sustainable mitigation, but continued research is crucial for practical implementation.
