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 case and what can be done to increase source separation is also part of our research focus. And we are not alone in looking for opportunities to transition our waste systems into something more sustainable. A recent popular science article in the magasin Extrakt, sponsored by the Swedish Research Council Formas, featured an interview with Jennifer McConville on what is needed to implement these systems at a large scale.
