ABOUT
The APOLLO project, an acronym for “A Proactive Approach to the Recovery and Recycling of Photovoltaic Modules” is a 36-month research project co-funded by the European Union’s Horizon Europe research and innovation programme under Grant Agreement No. 101122277

APOLLO will create a circular approach to link legacy recycling, future production, and future recycling. A pilot line will be demonstrated and used to process an input of 40 tonnes of PV waste which will be recycled, resulting in enough reclaimed materials for 1 tonne of remanufactured silicon and 30 exemplar PV modules. Incoming modules will be streamed by glass composition, enabling batch recovery of high-quality glass, to be used for new solar-grade glass. A novel continuous ‘sonification’ technique, (ultrasonically excited etchant) will rapidly separate silicon, silver, copper, and other metals in a sequence along a pipe-based process. Used liquid etchants will be recycled in a closed loop resulting in low waste, and a small footprint. Further, recovered silicon will be refined to a purity suitable for new PV-grade ingot growth.
-
The objective is to deliver purified silicon with a minimum purity of 99.9999%. Multiple innovations increase the percentage of weight recovery from 18% to 93%.
