Phosphorus recovery from sewage sludge - 21/10/2020 Bacteria help to recycle phosphorus Biotechnology for the bioeconomy: in something known as the P-bac process, sulphur bacteria extract phosphorus from sewage sludge ash. Phosphorus is one of the key building blocks of life and an essential nutrient for plant growth. When there is not enough phosphorus in the soil, farmers apply it via organic or mineral fertilisers.https://www.biooekonomie-bw.de/en/articles/news/bacteria-help-recycle-phosphorus
