Fraunhofer Institute for Manufacturing Engineering and Automation IPABio-based paints are a future-oriented alternative to conventional oil-based paints. These innovative coating materials are made from renewable raw materials such as plant starch or from waste products. Using these materials makes a major contribution to reducing dependence on fossil-based resources and reduces environmental pollution due to the lower CO₂ emissions and sustainable use of waste.
Fraunhofer IPA is currently working on the development and integration of natural materials in paint production, including for binding agents, filling agents, pigments and similar components. There is a particular focus on chitin, chitosan and feather keratin. These bio-based substances are byproducts of the food industry (shells of crustaceans and feathers from the processing of hens) and can be integrated into paint production to conserve resources as part of the circular economy. Starch from maize or potatoes also demonstrates significant potential for use as a natural binding agent in bio-based paints and reduces the need for petrochemical raw materials.
