The anticipated wave of end-of-life (EOL) solar panels has raised concerns about waste management, as the industry must address both the disposal and recycling of this equipment. 2. The Recycling Process for Solar
Learn MoreThe 2 potential EoL treatment scenarios explored in this study are incineration and pyrolysis. In general, the life cycle assessment of fluorine-free backsheet material shows better environmental performance than fluorinated backsheet material for both EoL scenarios.
Fluorine is released to natural waters through chemical weathering of F-bearing minerals (e.g., fluorite). For dissolved F −, global concentrations in rivers vary widely, ranging from ~0.1 to >1,000 mg/L in some volcanic provinces (Ali et al., 2016; Chowdhury et al., 2019 ).
In general, the life cycle assessment of fluorine-free backsheet material shows better environmental performance than fluorinated backsheet material for both EoL scenarios. For incineration scenario, the environmental impact of fluorine-free backsheet is evidently better than fluorinated backsheet across 11 out of 12 investigated impact categories.
Therefore, several experimental trials were conducted to measure fluorine transfer into the gas phase at 300 °C, 400 °C, 500 °C, and 900 °C (for pyrolysis) and at 750 °C, 850 °C, and 950 °C (for incineration). Ultimate analysis and heating values of the backsheet samples. Experimental conditions-pyrolysis experiments.
The content of fluorine gases in the atmosphere is so small (averaging ~1.5 ppbv; Russell et al., 1996) that despite recent rising concentrations (Cheng, 2018 ), changes in the atmospheric reservoir of F do not factor significantly in its global budget. The mean residence time of HF in the atmosphere is about 4 days (Cheng, 2018 ).
Furthermore, because of the release of high amounts of hydrogen fluoride, as well as the presence of halogenated hydrocarbons and halogenated aromatics in pyrolysis products, it can be concluded that pyrolysis is not an environmentally feasible pathway for fluorinated backsheet. The authors declare that they have no conflict of interest.
