Waste to Water (W2W) // In some arid regions of the world where there is both a lack of drinking water and high accumulation of waste, the so-called W2W technology can be put to good use. W2W is an innovative technology that sustainably converts waste into energy and thus specifically contributes to the production of drinking and service water supplies.

Technical approach

The underlying principle of W2W technology is a simple and straightforward idea. So why should regional waste not be used for alternative energy production which can be fed directly into desalination plants to generate valuable drinking and service water? 

There are various combustion processes that use waste to produce heat and steam. The most common method is grate firing – a process that automatically and continuously feeds in fuels on a conveyor belt and burns them on a grate. In the combustion chamber, temperatures reach up to 1000 °C. The heat can be used to run water desalination plants which require an enormous amount of energy. Such plants are for example urgently needed in the countries of the Middle East and North Africa so that the water shortage there can be adressed. The efficiency of these plants delivers clear ecological and economic advantages; it ensures that waste is disposed of in an environmentally sound way while simultaneously resolving the water shortage in these regions.


Particularly in the light of the enormous amount of energy needed to desalinate sea water, and the increased use of fracking technology, W2W offers considerable potential for saving crude oil and natural gas as an energy source for sea water desalination. At the same time, raw material prices which have come under pressure as a result of fracking can be stabilised through the broad application of W2W. 

We additionally take a very regional approach with regards to our projects. In order to avoid long and inefficient transport routes, we aim to set up the plants where waste is generated. On request, we also arrange contacts between international manufacturers and state investors in the area of plant construction.
