Project :

For several years waste recycling activities have become an integral part of consumer goods life cycle. Nevertheless, some specific waste flows remain poorly recycled as the “Best Available Technologies” cannot cope with them due to technological and/or economical reasons.


The objective of the Phoenix project was to find out a technological and economical solution to tackle the problem of recycling low-grade poly-metallic materials. An innovative process based on the bacterially-assisted dissolution of metals in oxidizing acidic media, commonly called bio-hydrometallurgy, has been developped.


The research program started in 2009 and has quickly led to very encouraging results which have been diffused in international conferences and scientific journals (see open repository).

Scale-up to the industrial level is planned by 2014
