There’s been an exciting new discovery in Kenya in the fight against plastic pollution: mealworm larvae that are capable of consuming polystyrene. They join the ranks of a small group of insects that have been found to be capable of breaking the polluting plastic down, though this is the first time that an insect species native to Africa has been found to do this.
Polystyrene, commonly known as styrofoam, is a plastic material that’s widely used in food, electronic and industrial packaging. It’s difficult to break down and therefore durable. Traditional recycling methods – like chemical and thermal processing – are expensive and can create pollutants. This was one of the reasons we wanted to explore biological methods of managing this persistent waste.
The lesser mealworm is the larval form of the Alphitobius darkling beetle. The larval period lasts between 8 and 10 weeks. The lesser mealworm are mostly found in poultry rearing houses which are warm and can offer a constant food supply – ideal conditions for them to grow and reproduce.
