  • In January, a European consortium with 11 partners from industry, academia, non-profit and research institutes, launched a three-year project with a budget of โ‚ฌ9 million ($9.84 million) to demonstrate the viability of tapping into PV panel recycling for silicon supply.

Dubbed Fostering A Recycled European Silicon Supply (FORESi), the project considers all the technical, economic and environmental aspects of recycling and re-using end-of-life modules.

It has several enabling technology goals. Building on an assessment of state-of-the-art European practices for the recycling of end-of-life PV panels, the team will develop a system that tests panels for reuse or repair. A process will be developed to dismantle to extract the raw material silicon from the non-reusable panels. In addition, new technologies will be utilized to purify the silicon to a level of purity sufficient to produce new PV panels and batteries, according to the project team.

The consortium members include Beglium-based Recma, Latvia-based Latvijas Tehnologiskais Centrs Nodibinajums, Hungary-based Bay Zoltan Alkalmazott Kutatasi Kozhasznu Nonprofit Kft, Italy-based Applied Materials Italia, Slovakia-based Slovenska Technicka Univerzita V Bratislave, along with several France-based entities, including Boralex, Mondragon Assembly France, Carbon, Hespul Association, and Commissariat ร  l’รฉnergie atomique et aux รฉnergies alternatives (CEA).

The project coordinator is Sipow, a Norwegian startup company that aims to produce monocrystalline pure silicon combining innovative low-cost methods with silicon recovered from end-of-life solar panel waste scrap.

The project is one of the latest groups to pursue innovative end-of-life solutions for PV panels. Others include France-based Rosi Solar and Italyโ€™s Tialpi, as well as Japanโ€™s Rexia Corporation, a joint venture between conglomerates Marubeni Corporation and Hamada. Others include research groups at the U.S. Department of Energyโ€™s National Renewable Energy Laboratory (NREL) and Australia’s University of New South Wales

Green Building Africa promotes the need for net carbon zero buildings and cities in Africa. We are fiercely independent and encourage outlying thinkers to contribute to the #netcarbonzero movement. Climate change is upon us and now is the time to react in a more diverse and broader approach to sustainability in the built environment. We challenge architects, property developers, urban planners, renewable energy professionals and green building specialists. We also challenge the funding houses and regulators and the role they play in facilitating investment into green projects. Lastly, we explore and investigate new technology and real-time data to speed up the journey in realising a net carbon zero environment for our children.
