Environment-friendly Energy Transition

Switzerland has firmly resolved to pull out of atomic energy in a step-by-step program. The Federal government’s Energy Strategy 2050 envisions the expansion of hydroelectric power and the increased use of other renewable energy sources. Eawag is researching the impacts of this energy transition on Swiss waters and society and developing processes for a more efficient use of energy from various sources.

It’s no secret that urine contains valuable nutrients – or that diluting them with water which is then flushed into sewers is not the most sustainable way of managing this resource. But how can urine be kept out of wastewater? Eawag has been investigating this question for many years, and one answer is to use a urine-diverting toilet to separate it “at source”. What may sound simple turned out in practice to be a tricky task, and several generations of toilets were needed to optimise the source separation technology to the point where it can be more widely deployed.  Read more

Aquatic organisms are adapted to harsh conditions at high altitudes and are tolerant of a certain level of disturbances. However, according to a study conducted in the canton of Valais, frequent flushing of water intakes leads to a dramatic decline in populations of macroinvertebrates, such as insects or worms.

The larvae of black soldier flies feed on organic waste matter. This has the potential not only to alleviate the waste problem in many countries, but also cut greenhouse gas emissions from waste disposal by around half. Read more

Strategic area of focus "Energy"

Within the framework of the ETH Domain’s strategic area of focus «Energy», Eawag investigates the environmental impacts of energy production, the acceptance of alternative energy supply, the potential for energy savings and energy production from wastewater. Click for a complete project list.

Selected research projects

Watercourses are among earth's most biodiverse ecosystems. However, they are also under severe pressure from construction work and hydropower generation, among other things.
Sustainable urban water and wastewater management applied and implemented in the modular NEST building.
This project aims at providing a better insight into the public preferences of the Swiss population for the suggested hydropower expansion.
