Clean Water

Unevenly distributed water

More and more often, entire regions are drying out—while other regions are being devastated by catastrophic floods. The uneven distribution of water is facing the human race with problems that were previously unimaginable. Good management and technology adapted to local needs can help in the search for a solution

Water as a resource: distribution, costs, availability

Water is distributed extremely unequally throughout the world. Where is this resource available in abundance, and where is it scarce? Who wastes it, and who uses it sparingly? And how much does this important raw material cost? A numerical overview

Evonik: Strategies for saving water

Nothing can happen at Evonik without water, which is indispensable for cooling, for example. To secure supplies and conserve resources, different strategies are used depending on the location—from rainwater retention basins in South Africa to high-tech filters in Thailand and recooling systems in Germany. A look at sustainability around the world

How can we protect water?

Today a large proportion of our freshwater is disappearing unused into the ocean, causing additional rising of the sea level. The hydrologist Dr. Johannes Cullmann works as a scientific advisor for the United Nations. He believes that the water challenge can still be solved at the global level—if the steps are implemented at a faster rate than climate change

Water as a natural reaction medium

If synthetic organic chemistry is to survive, the transition from its dependence on petroleum products and organic solvents, in particular to nature’s reaction medium, water, must happen quickly

New Zealand: Cloudwarriors

Welcome to Aotearoa! In the language of New Zealand’s original inhabitants, the Māori, this name means “the land of the long white cloud”— a reference to a special cloud formation that is said to have guided Polynesian seafarers here a long time ago. This island group in the Pacific Ocean features a breathtaking natural environment that has a spiritual meaning for the Maōri and also shapes the country’s economy.
