Bioeconomy

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.

In Provence, the lavender fields are in full bloom again. This blaze of color may soon also be seen in Baden-Württemberg. In a joint research project, the German Institutes of Textile and Fiber Research Denkendorf (DITF), the University of Hohenheim and the company naturamus are testing suitable lavender varieties and developing energy-efficient methods for producing essential oil from them.

Mini-factories for producing bioplastics - 05/05/2022

Bacteria produce bioplastics: resource-saving and very environmentally friendly

Using living cells as mini-factories to produce plastic from nothing more than water, sunlight and carbon dioxide; plastic that is also 100 percent degradable – it sounds far-fetched but it actually works: researchers at the University of Tübingen have genetically engineered cyanobacteria so that they fill their cells to the brim with polyhydroxybutyrate. The researchers are now turning the idea into reality with the development of pilot plants.

Hemp: regional superfood and valuable source of protein

If there were a competition for the ‘crop of the future’, hemp would certainly be at the top. But not because of the intoxicating effect of some hemp varieties. Cannabis has the potential to help supply protein in the quantities required by a growing world population – in a sustainable way. The TASTINO project brings together researchers from academia and industry to work on ways to make the regional superfood available as a vegan alternative.

The annual highlight of the industry is the International Conference on Cellulose Fibres in Cologne (www.cellulose-fibres.eu), where the latest innovations were showcased last week: new cellulose fibre technologies for various feedstocks and a wide range of hygiene and textile products as well as alternatives to plastics and carbon fibre for lightweight constructions.

Making important raw materials for fine chemicals out of carbon dioxide really works. As part of the Max Planck collaborative project eBioCO2n, a team of researchers from Fraunhofer IGB have successfully performed a first ever fixation of CO2 via a multi-enzyme enzyme reaction driven by electricity yielding a prospective intermediate for the chemical industry. The process for electro-biocatalytic CO2 fixation was recently published and is…

For the second time, the nova Institute for Ecology and Innovation is honouring outstanding scientific research that provides sustainable solutions for the cellulose fibre value chain as part of the "International Conference on Cellulose Fibres 2022". The DITF Denkendorf is one of the six nominees.

Renewable raw materials and the circular economy in the textile industry - 08/12/2021

Outdoor equipment made from cellulose, castor oil and coffee grounds - functional and durable

VAUDE develops outdoor gear made from natural or recycled materials that are harmless to people and the environment while protecting against the wind and rain. The company relies on renewable raw materials, biobased plastics and the circular economy.

Novel fibre composite made from hop fermentation residues

Biogas plants produce energy-rich gas by fermenting biomass. This process generates both liquid and solid fibrous and particulate fermentation residues. Researchers at the German Institutes of Textile and Fibre Research (DITF) have now managed to create a resistant and water-repellent fibre composite material from solid hop residues that can be used as a veneer to coat wood panels.

Biorefinery: new paths to build our tomorrow

Sustainability is in vogue. And it’s not a question of wanting to be sustainable, but having to be: as the latest report from the Intergovernmental Panel on Climate Change shows, protecting the climate and the environment calls for swift action. Biorefineries that use renewable raw materials and recycle industrial raw materials are playing an important role in the bioeconomy concepts of many countries - including the state of Baden-Württemberg.

The bio-based industries continue their ascent marking a total contribution of 780 billion EUR, a notable increase of 30 billion EUR (+ 4%) compared to 2017. This represents a more than 20% increase compared to 2008 which is the earliest data taken into account in this series of reports by nova-Institute. The first report of the series was first commissioned by the Bio-based Industries Consortium (BIC) in 2017.

In August 2021, the BioMat Pavilion 2021 was inaugurated on the campus of the University of Stuttgart in a ceremonial setting and in compliance with the hygiene concept. The core of the elegantly curved lightweight construction is an active-bending structure made of natural fibers, reminiscent of bamboo. It was developed as part of the "LeichtPRO" research project.

The Hallertau is Germany's largest hop-growing region. During harvesting, hop bine chaff is left over, which is converted into environmentally friendly bio natural gas on site in a biogas plant. But that is not the end of the utilization chain for this fiber plant. Researchers at the German Institutes of Textile and Fiber Research Denkendorf (DITF) have used the plant-containing biogas digestate to produce a composite material that can be…

Textiles can be coated with the biopolymer chitosan and thus made water-repellent by binding hydrophobic molecules. The good thing is that this can also replace toxic and petroleum-based substances that are currently used for textile finishing. In the last few years Fraunhofer IGB and partners have developed technology to provide fibers with the desired properties using biotechnological processes and chitosan.

The wastewater treatment plant is turned into a vegetable farm, bio-based substances recovered from waste are being utilized to prevent oxidative spoilage in food packaging or provide environmentally-friendly and safe water-repellent coatings on functional textiles. In the EVOBIO project coordinated by Fraunhofer IGB, 19 Fraunhofer Institutes are working on solutions for a sustainable economy.

Packaging of the future

What will the packaging of the future look like, and what will be required of it? Can packaging be biobased, recyclable, sustainable and economic? In Baden-Württemberg, there are various approaches to developing packaging with the above properties from various sources including agricultural residual and side streams as well as municipal waste.

A vision: insect biorefineries as components of a sustainable bioeconomy

Eco-friendly and responsibly manufactured products are more in demand than ever before. Specific research is being carried out into materials and applications for a wide variety of uses. The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB is working with Hermetia Baruth GmbH on the vision of an insect biofactory that uses waste materials to produce a wide range of products such as biosurfactants, animal feed or foils.

More than just a nut – new products for the bioeconomy

Plants are often used for one particular purpose only. However, walnut trees have much more to offer than just delicious nuts. The AlpBioEco project is studying the potential of walnut trees for the bioeconomy and how the potential can be exploited commercially. The international team of researchers is also focusing on apples and herbs.

Providing growledge – resources and products for the bioeconomy

Miscanthus and hemp are biomass plants that can be used as raw materials for a wide range of products and can be grown on land areas that are currently underutilised. A European consortium led by the University of Hohenheim in Baden-Württemberg has started a five-year project to demonstrate the economic potential of these plants.

The alternative: “bioplastics”

Plastic waste takes years to decompose and pollutes the environment. Nevertheless, plastics are an indispensable part of everyday life. It is therefore all the more important to find a meaningful alternative that is sustainable, environmentally friendly and has better properties and more functionality than conventional plastics. In addition, such an alternative should not be dependent in any way on fossil resources.

Biocarbon fibres made of lignin

Carbon fibre is increasingly found in airplanes, cars and wind turbines. Carbon fibre is still made from oil and relatively expensive. However, this is soon to change. Researchers from the German Institutes of Textile and Fibre Research in Denkendorf (DITF) are working on the development of cost-effective carbon fibre made of lignin, a by-product of papermaking.
