Wasser 3.0: #detect|remove|reuse - 31/10/2023

How to sustainably remove and recycle microplastics from water

We all pollute our water with things we use in our everyday lives. In the process, microplastics and micropollutants accumulate in sometimes significant quantities and are difficult to remove. This has increasingly devastating consequences for our health and the environment. Wasser 3.0, a non-profit start-up from Karlsruhe, has declared war on this problem by developing a customisable process to detect, remove and even recycle these pollutants.

Textiles are a given in civil engineering. Until now, textiles made of resistant synthetic fibers have been used for this purpose, having a long lifetime. For some applications, however, it would not only be sufficient but even desirable for the auxiliary textile to degrade when it has done its job. Natural fibers, in contrast, often decompose too quickly. The DITF are developing a bio-based protective coating that extends their service life.

Microorganisms degrade biobased turf infill - 17/10/2023

Eco-friendly artificial turf: a sports pitch that’s good for people and the environment

There are thousands of artificial turf pitches in Germany. They are extremely practical, but often not at all environmentally friendly. When it rains or the pitch is used, plastic particles from the rubber granules can be released into the envronment, where they remain. Researchers at the University of Stuttgart along with the company TECNARO are now developing an artificial turf with an infill that biodegrades as soon as it leaves the pitch.

Doubling food production, saving water, and increasing carbon storage capacity – this may sound paradoxical, but would be theoretically feasible. Reaching this goal, however, would require a radical spatial reorganization of land use. This is the conclusion of researchers from Karlsruhe Institute of Technology (KIT) and the Heidelberg Institute for Geoinformation Technology (HeiGIT) of Heidelberg University.

Researchers at the University of Hohenheim are working on an alternative to fish consisting of microalgae. Advantage: Microalgae have high quality ingredients and also contribute to carbon storage.
