On 2 December 2025, the ReNu2Cycle project partners presented their novel methodology with selected indicators to assess the sustainability of recycling derived fertilisers (RDF) compared to conventional mineral fertilisers.
Designed specifically for RDF, this sustainability assessment offers a transparent, multi-criteria framework using 15 ecological, economic, and social indicators, aligned with sustainable economic principles and the UN Sustainable Development Goals.
