Bio-based paints

Bio-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.

Overview of the benefits of bio-based paints:

• Sustainability: By using renewable raw materials, bio-based paints contribute to the reduction of fossil-based resources and promote sustainable business.
• Reduced environmental pollution: Compared with paints based on petrochemicals, bio-based paints reduce CO₂ emissions and are often more biodegradable.
• Circular economy: The use of waste products, such as chitin and hen feathers from the food industry, makes it possible to implement a production process that conserves resources and reduces waste.

Many possible applications

Whether indoors, in the construction industry, in the automotive industry or on furniture, bio-based paints can be used in a wide range of applications.  

Bio-based paints can be used to achieve high-quality, durable coatings that represent an alternative for the modern market that is environmentally friendly and harmless to health.
