On 25th October, the kretsloppsteknik research group hosted a farewell symposium in honor of Professor Håkan Jönsson. At SLU, Prof. Jönsson has been leading research and education on the topic of nutrient recycling from wastewater and food waste since 1993, when the topic was first introduced at the department of energy and technology. It was under his lead, the research group kretsloppsteknik (environmental engineering) was established.
In his farewell presentation Prof. Jönsson explored many topics such as composting, source-separation of wastewater, urine diversion and recycling, systems analysis and environmental impact assessment of urine diversion, etc. Click here to access the presentation which recaps the work, research and contributions of Prof. Jönsson to various subject areas over the years.
Prof. Jönsson closed the symposium with further remarks and a vote of thanks. Continue reading Lessons learnt towards sustainable resource loops, and remaining challenges
What is ‘New Sanitation’ according to Professor Grietje Zeeman from Wageningen University in the Netherlands? How has the practical experience been so far with the upflow anaerobic sludge blanket (UASB) reactor for blackwater treatment and bio-flocculation of greywater? Can micropollutants be mitigated through composting of anaerobic sludge? Are heavy metals from wastewater really a problem in agriculture? Interested in learning more about how these technologies have been applied at full scale in Sneek, Venlo, Wageningen and The Hague? Click here to access Professor Zeeman’s presentation.
