Feed production is destroying ecosystems worldwide. Insects represent a high-quality alternative to conventional feed. By recycling industrial side streams, insects enable a circular economy. So far, however, insect proteins are not competitive. In the Innovation Sprint, a prototype of a decentralized recycling plant is built. In the plant, industrial food waste is fed to insect larvae. Thanks to the innovative design and intelligent control software, the process is fully automated despite low investment costs. Thus, the recycling plant can recover nutrients from food waste at small and medium-sized food producing companies. The sustainable insect proteins replace soy and fish meal as animal feed.
