Using bone char as phosphate recycling fertiliser: an analysis of the new EU Fertilising Products Regulation

Abstract

Abstract Background Phosphorus recycling is an important cornerstone of sustainable phosphorus management and required to establish a circular economy in line with the EU Green Deal. Animal bones contain phosphate which can be recovered and processed into bone char. Animal bone char has a fertiliser potential. In the past, the EU lacked measures to market these fertilisers on the internal market. With the adoption of the Fertilising Products Regulation in 2019, the EU sought to incentivise recycling fertiliser production. Against this backdrop, the aim of this paper is to first provide the key elements of the new regulation and to second assess the extent to which it enables marketing bone chars as fertilisers. To this end, a qualitative governance analysis is applied. Results Results show that the Fertilising Products Regulation closes an important regulatory gap by establishing the legal framework for diverse recycling fertilisers, including bone char fertilisers. However, a lengthy adoption process hinders the marketing of bone char fertilisers and contaminant limits require improvement. Conclusions Ultimately, the promotion and use of recycling fertilisers is a necessary but complementary approach for the circular economy. A comprehensive transformation of the sector is needed to align it with global environmental goals.
