Status quo

Conventional mineral wool and plastic foams for thermal insulation are characterized by energy-intensive production and complicated recycling and disposal processes. Biodegradable thermal insulation materials made of cellulose fibres offer an alternative to this. Up to now, these materials are usually available as panels, mats, felt or loose fillings. In order to dry the components after foaming, they must be pressed. The production of more voluminous foams is therefore a difficult task.

Our technology: Innovative production process for fibre foam

Voluminous fibre insulation foams made of renewable raw materials now can be produced using special production processes. The foam is made of cellulose fibres, water and different additives and can be dryed without applying pressure in a simple way.


  • Lower material, cost and energy consumption during production.
  • More voluminous foams by omission of the production step pressing.
  • Biodegradable and sustainable.

Current stage of development

Technology-Readiness-Level: Level 3. Proof of Concept is shown with two different production processes. Test specimens were made and measured.

Application possibilities

Thermal insulation material for sustainable construction. Can also be used as packaging material or for sound insulation purposes.

Commercialization opportunities

For the implementation of the technology, we are looking for interested companies who would like to extend their product portfolio or open up new business fields. There are various possibilities for cooperation between the industrial partner and TU Darmstadt: from an exchange with the know-how carriers of the technology up to a close cooperation in case of further development needs. The technology is protected by intellectual property rights and can be used by the industry partner after a sale or licensing agreement.
