The demand for clean drinking water is rising, while water scarcity is also intensifying—driven in part by climate change. At the same time, the growing scarcity of raw materials, combined with geopolitical tensions and increasing demand in emerging economies, makes reducing our dependence on these resources more important than ever. Embracing a circular economy helps address these challenges by limiting waste production and minimising environmental harm. The problem of water scarcity leads to a demand for solutions that contribute to efficient water use and reuse. Circular solutions regarding water play an increasingly important role across all industries and especially in sectors where water is an essential part of the production processes. Examples are energy (hydrogen transition), sustainable agriculture and sustainable food production.
