H2020 project PEACOC
PEACOC is a pre-commercial pilot for the efficient recovery of precious metals from European end-of-life resources with novel low-cost technologies. First-of-its-kind, low-cost and eco-friendly technologies are used for efficient recovery of gold, silver and platinum group metals (PGMs) from waste.
Precious Metals and PGMs are widely used in a variety of economic sectors in many industrial applications worldwide. Due to their unique properties, such as low corrosiveness, catalytic properties and low electrical resistivity, there are often no alternatives to replace them.
Europe is the world top consumer of PGMs, thus it is becoming highly dependent on imports, which are essential for its economy. For those reasons, the European Commission (EC) has classified PGMs as Critical Raw Materials. This EU-funded project aims at solving the current challenges that limit the recovery of precious metals at massive scale, while exploiting the vast potential of EU secondary resources.
The PEACOC project will research and demonstrate - on a pre-commercial level - novel, effective, low-cost and environmentally friendly technologies for recovering gold, silver and PGMs from complex waste mixtures. It aims at treating end-of-life products in Europe, including spent autocatalysts, low/mid-grade printed circuit board assemblies and photovoltaic waste.
The project concept is based on previously-developed recovery and refining technologies in the frame of the PLATIRUS H2020 research and innovation project.
The selected technologies, namely microwave-assisted leaching, gas-diffusion electrocrystallisation and deep eutectic solvents for recycling and recovery of PGMs, will be further scaled up to technology readiness level 7.
The main results of the PEACOC project can be read in the following publications:
Scientific publication: Recovery of copper, zinc and lead from photovoltaic panel residue
Numerical investigation of the precipitation of metal ions by the gas-diffusion electrocrystallization
Pt, Pd and Rh recovery from End-of-life Products and Nanoparticle synthesis by gas-diffusion electrocrystallization (GDEx).
