Legislative issues surrounding the application of insect larvae and compost worms for biobased valorization of manure, digestate and other organics

This document gives a short overview of the current (national and EU) legislation (as on December 2022) on the bioconversion of several organic streams by insect larvae and compost worms. Legislation concerns different substrates, the status of the invertebrates themselves and the status of the resulting insect frass and vermicompost. Dutch and EU legislation on the production of insect larvae as feed for farmed and pet animals has been developed and adapted in recent years, for example the allowance of different feed products from designated insect larvae species as fish, poultry and pig feed. The legislation is still in development. Recommendations are given.
