InBiRa: Insect biorefinery turns food leftovers into new products

Insect larvae can convert food leftovers and waste into secondary raw materials for technical products and cosmetics. Researchers are looking to establish an insect biorefinery for this purpose at the Fraunhofer IGB in Stuttgart. The InBiRa project is financed with a total of 3.8 million euros in EU and Baden-Württemberg state funding.

Pharmaceutical products, medicine, proteins, and nutrients are usually produced on an industrial scale in a bioreactor. Although the technology is well established, more research is needed in order to be able to increase the production volumes. A visual inspection of the production is usually not possible because bioreactors are made of opaque steel.

The glass facade of a high-rise building can get so hot that you can fry eggs on it – a major factor in the overheating of our cities. At the same time, flood events such as torrential monsoon rains cause billions of dollars of damage annually. On October 4, 2022, a solution to both problems was presented at the University of Stuttgart.
