In Sweden, we consume on average 140 liter water per person and day. After we use the water, it must be treated before we can discharge it into nature Can we improve existing treatment processes or develop new that consume less energy and chemicals, take up less space, and remove pollutants more efficiently?

Waste streams such as wastewater and solid waste contain valuable resources such as energy, nutrients, and metals. How can we recover these resources from the waste streams?

Past industrial activities has led to pollutions. Soils, sediments, and groundwater are contaminated in many parts of the world. In Sweden, the Swedish environmental protection agency has identified 26 000 contaminated sites. How can we manage these sites?

Complex microbial communities are important in many environmental engineering processes. The degrade pollutants and help us recover resources. To optimize processes, we must understand how operational and environmental factors affect the function of microbial communities, and we must learn to control them. Methods to assess biodiversity and changes in community composition are helpful in this research.
