Bioeconomy

The University of Stuttgart is contributing to innovations for climate protection as part of the EU project "Smart Circular Bridge". An old material is being rediscovered: flax has been with us for thousands of years in the form of clothing, sacks, and robust ship's ropes. Now the plant fibres are experiencing a renaissance and could become the building material of the future.

Sustainable reinforcement of e-bike battery cases

Ansmann AG from Assamstadt provides mobile energy solutions with a focus on sustainability. The BioBattery project, which was awarded the Baden-Württemberg Bioeconomy Innovation Prize, saw Ansmann AG working with the Fraunhofer LBF in Darmstadt to develop a natural fibre reinforced plastic composite for use in e-bike battery cases.

A viscous biopaste that is easy to process, solidifies quickly and is suitable for producing even complex structures using the 3D printing process has been developed by a research team headed by Prof. Dr. Marie-Pierre Laborie from the Chair of Forest Biomaterials at the University of Freiburg. The wood-based biodegradable synthetic could potentially be used in lightweight construction, amongst other things.

A soft material that heals itself instantaneously is now reality.

Magnetised algae as microrobots for medical and environmental purposes

Algae, for most of us, is something that lives in water courses that we occasionally find unpleasant. However, that is to do them a wrong. These extremely versatile and frugal organisms might in future prove to be extremely important. Scientists at the University of Stuttgart are investigating how algae can be used as microrobots in biomedicine and environmental remediation.

Textiles: water-repellent thanks to fungal proteins

Outdoor lovers and athletes love them: water-repellent jackets and trousers. However, many consumers are unaware that the chemicals used to functionalise the textile surface often pollute the environment. Organic fluorine compounds (perfluorocarbons = PFC) are usually added to textiles to make them water-repellent. Scientists at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Hohenstein Group are researching an…

Development of innovative, ecological construction materials and methods at the University of Stuttgart

The Baden-Württemberg construction sector is currently experiencing a similar boom to the one that occurred in 1996. Between January 2016 and January 2017, low interest rates and uninterrupted demand for housing has led to an increase in orders of almost 10%1. A shift from conventional building materials to biobased building materials and products would likely also support the transition to a bioeconomy in this economic sector. The Institute for…

Building with bamboo and fungi – renewable buildings of the future

Bamboo to replace steel and fungi to replace concrete: a research group at the Karlsruhe Institute of Technology (KIT) is working on ways of using renewable raw materials in the construction industry. Biological building materials such as bamboo and fungal mycelium could one day replace conventional materials such as steel and concrete.

PURCELL – cellulose to replace plastics

Glass fibre-reinforced plastics have become an integral part of our everyday life: in cars, playground slides, swimming pools or on facades, such composites are used wherever stability is required. Unfortunately, both production and disposal are far from sustainable. Scientists from the German Institutes for Textile and Fiber Research Denkendorf have now developed an innovative material made from pure cellulose, which has practically the same…

Biobased electrode materials for future energy storage systems

Novel biomass materials suitable for various applications need to be developed in order to establish a biobased raw material platform within the bioeconomy. These biobased materials must be able to compete with conventional fossil fuel-based materials, both from a technological and economic point of view. Researchers at the University of Hohenheim are working on the development of conductive carbon materials from biomass with the long-term goal…

Biogranules for industrial foils and a new class of products

Biogranules are a starting point for the production of a wide range of novel biobased materials: in a BMBF-funded project called ”EnzymaCell”, a company called TECNARO and its cooperation partners have developed thermoplastic biofoils. The innovative combination of cellulose and natural additives has led to a material with many application possibilities.

Straw replaces plastics – a material revolution

Junior professor Dr.-Ing. Hanaa Dahy and her team from the ITKE in Stuttgart are developing everyday biobased materials that have a wide range of possible applications. The materials can be used for thermal insulation, designer furniture, yoga mats or resilient flooring in sports halls. The researchers use techniques from the plastics industry to process recyclable and compostable materials.

Nanofur for cleaning up accidental oil spills in water

Accidental oil spills such as those following oil disasters need to be cleaned up as quickly as possible. Researchers from the KIT in Karlsruhe have now developed an environmentally friendly process that can eliminate oil spills effectively. Nanofur is a material that imitates the fine hairs of aquatic ferns and is capable of absorbing large amounts of oil within a relatively short time.

Biobattery made from unused and windfall apples

The disadvantage of wind and solar energy is that they cannot be produced continuously nor can they be stored, at least not yet. High-performance batteries that can store intermittent renewable energy sources might change this in the future. Sodium-ion batteries would be both a cheap and environmentally friendly possibility. Prof. Dr. Stefano Passerini and his team at the Karlsruhe Institute of Technology (KIT) have developed a battery that…

Stuttgart-based ZSW turns wood and electricity into gas

It is rather reassuring to know that fossil energy carriers can be replaced by renewable ones. However, the difficulties are always in the details. For example with regard to the storage capacity of electricity produced with sun and wind; or with regard to the use of biomass to produce natural gas substitutes. The Stuttgart-based Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) has a number of solutions up its sleeve for…
