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.

Compostable nappies - 14/10/2021

Nappies for a sustainable bioeconomy

In an EU-funded project, the Tübingen-based biotech company Novis is working with international partners to develop a fully compostable nappy that contains no plastic parts. This could reduce the huge quantities of used disposable nappies that have been produced to date and the enormous costs of disposal, as well as avoiding the greenhouse gases produced when they are incinerated.

Hygiene and health company Essity is today presenting a breakthrough in sustainable tissue production and is beginning production based on pulp from wheat straw. The plant in Mannheim, Germany, is the first of its kind in Europe, and the first on a large-scale tissue production in the world.

Start-up PROSERVATION - sustainable packaging - 21/09/2021

Husk as a substitute for polystyrene: packaging materials with a good conscience

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.

As a rapidly growing renewable raw material, bamboo is an ideal substitute for wood. However, bamboo’s susceptibility to mold in damp conditions poses a problem. Researchers at Fraunhofer have now analyzed bamboo’s response to moisture under specific climatic conditions. By using simulation software, building owners can plan and implement measures to prevent the growth of mold.

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.

An international research team has calculated the potential for material efficiency strategies in residential buildings and passenger cars. Up to two-thirds of global emissions could be saved in these areas, provided that appropriate strategies are consistently implemented.

Plastics from the field - 12/08/2021

Great potential for biological residues

Huge amounts of waste are produced both during food production and by consumers.
