1. Sustainable argument: An anaerobic digestion plant produces circa 40% CO2. This could be better. Waste treatment with the help of larvae of the black soldier fly goes at least six times faster and gives 70% less emissions of CO2.
2. Commercial argument: Waste treatment with larvae gives a new organic waste stream, namely the adult larvae. These can be used as raw material for biobased products, such as biodiesel, all kinds of bioplastics, adhesives, coatings and green chemicals. Look here.

However, there is a legal hurdle within the EU, that goes back to the definition of farmed animals. See here.
