Earlier this year, Peter H. Seeberger was awarded the International Green Chemistry Prize for the production of a sustainable and cost-effective antimalarial agent. Now the biochemist from the Max Planck Institute of Colloids and Interfaces in Potsdam wants to drive structural change in Lusatia in Saxony and the Central German mining region together with his team.
About four kilograms of microplastics per person enter the environment every year in Germany as a result of washing synthetic fibers. The tiny particles then enter waterways via wastewater, where they are ingested by fish. However, some aquatic animals have a filter system in their gills that separates food particles from the water and thus also filters out microplastics.
Agricultural residues range from wheat and grapevines to hemp, hops, tomatoes and zucchini. A novel fiber technology, developed by CleanTech start-up BIO-LUTIONS and Zelfo Technology GmbH, enables this rich array of plant residues to be processed into sustainable products such as packaging and disposable tableware. For this, the developer duo from Schwedt was awarded the Brandenburg Innovation Prize in the plastics and chemistry category.
Bioplastics such as PLA (polylactide) are now used in many areas - from food packaging to dowels or children's toys. Nevertheless, their share is still low compared to conventional plastics based on fossil raw materials. The same applies to composites, which have to exhibit certain properties and therefore consist of different plastics. Here, too, there are now partially or completely bio-based materials. Researchers at the IfBB at Hannover University of Applied Sciences now want to prove that bioplastics can also withstand high temperatures and stresses.
In order to find an alternative to the often aggressive and allergenic detergents, the owner of a commercial cleaning company experimented with various plants. Ultimately, she came across the cleaning power of beetroots, which contain oxalic acid, and developed her own cleaning agent.
From offices to classrooms: Air filters have been booming since the outbreak of the pandemic. They can be used to remove virus-laden aerosols from rooms and thus reduce the risk of infection. Ideally, filter materials should also be environmentally friendly. For this reason, researchers from the Zuse community have taken a close look at nonwovens made of bioplastics as filter materials and examined them for filter performance and durability.
What remains after harvesting usually ends up in the biogas plant and is used for energy. The resulting fermentation residues are often taken as fertilizer in agriculture because of their high nutrient content. Researchers from the German Institute of Textile and Fiber Research Denkendorf have now shown that the recycling chain for fermentation residues does not have to end in the field, but that they can be further processed in industry as a raw material.
Household sponges, mattresses, car seats or insulating walls: it is hard to imagine everyday life without foams, whether hard or soft. However, the production of the petroleum-based material is not very environmentally friendly. Researchers at Kaiserslautern University of Applied Sciences think it's time for a change: Together with partners from seven countries, the team led by polymer chemist Sergiy Grishchuk wants to make foam and composite materials more sustainable.
Whether cream or lotion: natural cosmetics are in vogue. More and more manufacturers are therefore turning to natural ingredients to respond to the growing demand. BASF Care Creations is now launching a natural ingredient for skin care products. At the end of June, the Ludwigshafen-based company announced the launch of a new biopolymer called Hydagen Clean. It is designed to replace synthetic polymers in facial care, body care and styling products. According to the company, Hydagen Clean is made from 100% natural and renewable raw materials and is biodegradable.
One focus of the German sustainability strategy is the optimal use of raw materials in the sense of the circular economy. This includes the recovery of plastics made from fossil raw materials such as polypropylene (PP). Polypropylene contains the finite resource petroleum and is the second most important plastic of all. It is used primarily for packaging, but also in electronics and automotive engineering. However, PP is also a component of products such as carpets, which are made of composite materials and are difficult to recycle.
