Summary

This commentary challenges a study claiming mealworms do not chemically degrade expanded polystyrene, arguing that valid biodegradation conclusions require mass balance analysis and comprehensive analytical methods including gut microbiome, transcriptome, and metabolome characterization rather than limited chemical testing alone.

Polymers

Biodegradation of polystyrene products should be characterized on basis of mass balance and by comprehensive analytical methods associated with gut microbiome, transcriptome and metabolome.
