Earlier today, Prof. Håkan Jönsson, Pernilla Tidåker, and Prithvi Simha coordinated a student (from the Sustainable Food Systems master’s program at SLU) visit to a garden and a house owned by Håkan, who has designed a local system where most of the plant nutrients from the household are recycled back to the garden and used as fertilizer. For a very long time Håkan has implemented source separation in his own house and uses all source-separated urine and kitchen compost as fertilizer in his garden, where he grows vegetables and berry bushes. During the visit, the students saw how a small-scale source separation systems can look like and discussed options and challenges for future upscaling.
