The KNAP research project is set to take center stage at the IWA Resource Recovery 2025 conference in Leeuwarden (NL), with a presentation on the key interim findings on circular fertilisers. Next to that, conference attendees will be invited to enjoy the first-ever chips made from potatoes grown using circular fertilisers—including the innovative, market-approved Puraloop. This flavorful stunt is part of the KNAP research project’s mission to close the phosphate loop and promote circular agriculture.
