People and animals create lots of waste that is usually sent to landfills, incinerated, or stored in engineered ponds such as manure lagoons. Now, researchers report a potential removal method using insects, specifically black soldier fly larvae. In experiments, the larvae ate spoiled food, sewage sludge, or livestock manure, and removed most human-pathogenic viruses. The researchers say this demonstrates a step toward simple, environmentally friendly waste management.
