FoodsecURe: Food security through better sanitation: the case of urine recycling


Human urine contains essential plant nutrients. Hence, urine can serve as a “free” and locally available fertiliser. Successful, low-cost urine-diverting toilets (UDTs) that separately collect urine have been developed in Scandinavia and Europe and manufactured at large scale in Africa. A solution for stabilising urine into a solid fertiliser has also been developed. 

But why can't we recycle urine at scale?

In Sweden UDTs are used in some cottages, and the Swedish University of Agricultural Science (SLU) has developed a method to stabilise and dry urine into a fertiliser product, urine-based fertiliser (UBF). FoodSecure aims to implement this technology at a medium scale in Ethiopia.

JordbærSmak: En optimalisert moderne produksjonsteknologi for mer smakfulle norske jordbær


Det er et mål å øke produksjonen i den norske grøntsektoren, inkludert jordbær, med inntil 50 prosent de kommende 15 årene. For å oppnå dette må dyrkingssesongen utvides, men da trengs en mye bedre kunnskap om hvordan man kan påvirke planteveksten og ta i bruk teknologi for å overvåke og beskytte plantene, uten at det går utover kvalitet og smak.
