LIFE Polyphos Acid

Prayon is working on the development of an innovative process for the production of polyphosphoric acid based on the phosphoric acid wet process. Named LIFE Polyphos Acid, this project obtained the support of the LIFE+ Environment Programme of the European Union.

With a budget of about € 2.5 million (half of it being financed by the European Commission), the project started in July 2013 and is due to be finished in September 2017.  During this period, Prayon will run an industrial pilot to test the feasibility of the process on industrial scale.

The aim of the LIFE Polyphos Acid project is to offer a solution to the reduction of the carbon footprint and to the non-valorised wastes in the context of the polyphosphoric acid production.
