Municipalities are expected to provide solid waste management to their inhabitants, funded by tax revenue or/and waste treatment fees. In many low and middle income countries, municipalities however struggle to provide an adequate level of service; in such places the informal sector plays a major role in the collection and treatment of solid waste. In… Continue reading How to get the best value out of organic waste?

Dry fertiliser from urine
The saying ‘we are what we eat’ is only part of the story. What we eat is what we excrete, and this means plant nutrients. Human excreta contain the same nitrogen, phosphorus and potassium (N-P-K) as the fertilisers used to produce the food consumed (Winker et al., 2009). However, human excreta are considered unwanted waste… Continue reading Dry fertiliser from urine
The Road to Large-scale Implementation of Source-separation?
Within our research group we are working with several methods for returning nutrients from food and wastewater to agriculture. Source separation of waste flows can make for simpler treatment and higher quality of the recovered products. However, the use of source separation systems is far from wide spread. Trying to understand why this is the… Continue reading The Road to Large-scale Implementation of Source-separation?

What do farmers in South India think of human urine as a fertiliser?
Technological advances in the sanitation sector have made it feasible to safely recycle human wastes to agricultural areas to use as fertilisers. From a social science perspective, these developments open up a new array of questions: for instance, are farmers be willing to handle and use such fertilisers? How do farmers perceive such materials –… Continue reading What do farmers in South India think of human urine as a fertiliser?
