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.

The urgency of the ongoing climate change is increasing. There is no doubt that emissions must be drastically reduced at all levels, but that is not enough. To prevent the worst consequences of climate change, additional carbon sinks, so-called negative emissions, are needed. A recently published whitepaper clearly and scientifically substantiates that biochar is a key technology in this fight against climate change.

Germany generates around 38 kilograms of plastic waste per capita each year. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and the Fraunhofer Institute for Process Engineering and Packaging IVV are now working to establish a holistic concept for the sustainable use of biologically degradable packaging materials in the cosmetics industry. The project is focusing on polyhydroxyalkanoates (PHAs).

The European Environment Agency (EEA) recently published its new report “Biodegradable and compostable plastics – challenges and opportunities”. The report highlights many positive aspects of biodegradable and compostable plastics. Unfortunately, its interpretation in several media outlets focused exclusively on the few critical assumptions the report makes regarding consumer perception.
