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.

Researchers at the University of Freiburg quantify the amount of material needed to enable people to live without poverty. 1.2 billion people live in poverty. To lift them out of it, an average of about six tons of raw materials are needed per person and year – in particular minerals, fossil fuels, biomass and metal ores. This is the result of a study by researchers from the Chair of Sustainable Energy and Material Flow Management.
