The Unit performs both research and education, at both undergraduate and postgraduate levels. The main topic is systems and processes for safe recycling of plant nutrients from the city back to the food production, which is an essential part of a sustainable society, both in developed and developing countries. The research is based on systems analysis and process oriented. Important methods in the system analytic research is ”Substance Flow Analysis” (SFA) and ”Life Cycle Analysis” (LCA). The process oriented research is mainly focused on source separating sewage systems, sanitation/hygienisation technology, both for Swedish conditions and conditions in developing countries, and systems in the compost process.
We are responsible for the course "Safe Nutrient Recycling", 10 HEC, given within master programs in biology and environmental science, and for the courses "Selection of water and sanitation system", 10 hp, "Waste Management", 5 hp and "On-site wastewater systems", 5 hp, given in civil engineering program "Vatten och miljöteknik". The emphasis of the courses is on systems and processes (composting, urine separation, etc.) for the treatment and recycling of plant nutrients in sewage and organic waste, the courses also focus on treatment technologies and hygiene.
Project ongoing since: 2005
SLU Research Projects
Safe and effective use of resources in sewage and waste suitable for developing and middle income countries. Research includes nutrient recycling, protein produced from waste by black soldier fly larvae or worms, or compost technologies.
The Environmental Engineering Group at the Department of Energy and Technology studies nutrient recycling systems from waste to high quality, nutrient-rich products with small risks of spreading diseases. Recycling systems for nutrient rich waste, such as human urine, faeces, food waste, urban manure, slaughterhouse waste, etc. are studied. …
