Start-up PROSERVATION - sustainable packaging - 21/09/2021
Expanded polystyrene (EPS) packaging is very practical, but it is made from petroleum and is not very environmentally friendly in other ways either. Single-use plastic containers made of EPS have therefore been banned in the EU, but alternatives are also urgently needed. The Stuttgart-based start-up PROSERVATION has developed an ecological packaging material made from grain husks that could replace EPS and be just as effective.

Press release - 21/04/2023
In collaboration with the project partners CG TEC, Cordenka, ElringKlinger, Fiber Engineering and Technikum Laubholz, the DITF are developing a new fiber composite material (CELLUN) with reinforcing fibers made of cellulose. The matrix of the material is a thermoplastic cellulose derivative. CELLUN made from renewable biopolymers enables the replacement of glass or carbon fibers in the production of industrial molded parts.

Press release - 30/03/2023
Composite materials provide stability in aircraft parts, sports equipment, and everyday household items. However, most of these materials have a poor carbon footprint and are not naturally degradable. A more sustainable alternative has been developed by a team from the University of Stuttgart. This completely bio-based composite material is made of flax fibers and the biopolymer chitosan.

3D-Thermocell project - 17/05/2023
Replacing plastic – for example in packaging – is not that easy but nevertheless urgently needed. In the 3D-Thermocell project, researchers at DHBW Karlsruhe are currently developing new plastic substitute products made of thermoformable paper as a renewable resource, which should be cheap and light and easy to dispose of along with waste paper. The characterisation and application of demonstration models will start soon.

Dossier - 20/03/2017
Petroleum is the raw material for basic chemicals. Growing demand and dwindling resources mean that the chemical industry is increasingly focusing on renewable resources. Lignin is a wood component that is proving to be a promising resource. It is currently almost exclusively used for generating energy, although it could also be used for other purposes. In Baden-Württemberg, a research consortium is specifically focused on exploring its…

Article - 21/10/2019
Plastic plant pots are not good for the environment; strictly speaking, they should not even be disposed of in recycling bins. Alternatives such as coconut fibre pots are compostable, but not pollutant-free and not "bio" at all. The Karlsruhe-based company Fiber Engineering has developed a truly ecofriendly way to grow plants: pots made of hemp or grass, which are preserved with biological components and decompose completely within a…

rezemo GmbH - 26/06/2020
In Germany alone, around three billion disposable coffee capsules made of aluminium and plastic are sold every year. This creates a gigantic waste problem, as only a small proportion of the capsules can be recycled. Fully compostable wooden coffee capsules might be a solution to this problem. The capsules have been developed by a start-up company called rezemo, which also has other biobased packaging solutions in the pipeline.

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.

Press release - 29/09/2022
Fossil raw materials are limited and not available and extractable everywhere in the world – as we are becoming acutely aware of right now by the example of fossil fuels and rising energy prices. Renewable raw material sources will therefore play an increasingly important role in the future: as energy sources, but ideally also as suppliers of building blocks for more environmentally compatible chemicals and materials.

Preventing waste from instant meals - 05/10/2023
Many instant meals such as ramen soups have both a protective outer packaging and individual ingredients in small plastic sachets. To prevent this environmentally harmful waste, five students at the University of Hohenheim have developed a sustainable film based on eggshells and plant proteins that dissolves in hot water and is edible.

Diatoms as a biorefinery - 05/05/2023
Renewable raw materials that can be used as alternatives to fossil resources already exist. However, to turn them into everyday products, plant oils and other renewable raw materials not only have to be extracted, but often have to undergo complex chemical processing. Researchers at the University of Konstanz have now converted microalgae cells into tiny refineries to produce and upgrade raw materials, creating a supply of sustainable chemicals.

The AlbLavendel project - 20/11/2023
Blue-violet, fragrant fields like those in Provence may soon become a common sight in the Swabian Alb. As part of the AlbLavendel project, the University of Hohenheim along with the company naturamus GmbH and the German Institutes of Textile and Fibre Research Denkendorf has started to investigate the cultivation of lavender, the production of essential oils and the use of distillation residues for producing textile fibres in the local region.
