Recycling rare earths with peptides

Whether in smartphones, LED screens or wind turbines: rare earths are indispensable for the high-tech industry. Hardly any electronic device can do without the precious metals. But the raw material is limited and the German economy is dependent on imports, especially from China. Better and more sustainable recycling of rare earths could remedy this situation and would be a first step toward making Germany economically less dependent on imports.

Premiere for stage design from mushroom mycelium

"The Entrepreneur" by Kevin Rittberger at the Residenztheater in Munich is a premiere in two respects. When the curtain rises on December 9, 2022, at the Bayerisches Staatsschauspiel, not only the actors but also, for the first time, a stage set will be in the spotlight. An eight-meter-high tree trunk made of a sustainable material will be presented. A composite material made of wood chips and mushroom mycelium was used to build this backdrop.

From wheat straw to textile fiber

The textile industry's interest in sustainable materials is growing. In particular, this revolves around alternatives to cotton, but also around replacing petroleum-based synthetic fabrics. Expanding the raw material base for textile fibers is the goal of a new research project. As part of the CRF-Sraw project, researchers at the University of Hamburg, together with fiber expert J. Rettenmaier & Söhne, now want to make agricultural residues usable for fiber production.

Networking for the bioeconomy

The emergence of the Green movement in the 1980s was formative for Birgit Lewandowski. The plans for the construction of a hydroelectric power plant on the Danube near Vienna were a wake-up call for the native Austrian and at the same time set the course for the future. Having grown up in the countryside in the green belt of Vienna, the preservation of the Hainburger Au was close to her heart.

Innovation award for lightweight pallets made of biopolymer foam

When it comes to storing and loading heavy goods, industry often turns to so-called Euro pallets. These load carriers are usually made of wood, can be used universally and can carry up to 1,500 kilograms. Although there are also pallets made of plastic, these are still used quite rarely compared to the wooden variant. Researchers from the Fraunhofer Institute for Chemical Technology ICT in Pfinztal near Karlsruhe have developed a high-performance lightweight pallet made of foamed biopolymers.

Ring shaped mosquito repellent

Mosquitoes can make spending time outdoors miserable - especially if you don't have a suitable insect repellent to hand. There are sprays or creams that are supposed to keep the insects away. But if you spend a lot of time outdoors, you need to renew your protection regularly. Researchers at Martin Luther University Halle-Wittenberg (MLU) have now found a way to make the protection last not just hours, but even days.

Making reusable plastic recyclable

The new Packaging Act, which came into force in January 2019, paved the way for more bio-based packaging and increased recycling rates. In particular, the recycling of plastic packaging takes on a high priority. Single-use plastic products such as eating utensils or drinking straws have been banned throughout the EU since last year and have since been gradually replaced with sustainable materials. However, reusable products such as beverage bottles are also made of plastics and are largely disposed of or incinerated at the end of their life cycle.
