Waste recycling in the healthcare sector - 30/01/2024

Sustainability in medical technology: a particular challenge

Quality and safety of medical care are top priorities in the healthcare sector. However, this is often at the expense of climate protection, as not only are energy and raw material consumption very high, but so is the amount of waste generated due to the large number of disposable products. Sustainable product design and improved recycling strategies are therefore required to reduce waste and the CO2 footprint.

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.

Epigenetically active drugs enable the cell to read parts of the genome that were previously blocked and inaccessible. This leads to the formation of new mRNA transcripts and also new proteins, as scientists from the German Cancer Research Center and the University Hospital Tübingen have now published. These "therapy-induced epitopes" could help the immune system recognize cancer cells.
