Styrofoam is a persistent plastic that is difficult to decompose naturally in the environment, is microplastic, which causes its accumulation as a major contaminant in soils, rivers and oceans. One method to process styrofoam waste is biodegradation. Biodegradation of styrofoam waste using mealworm was carried out by giving styrofoam as the main feed. This research aims to increase the biodegra…
