Environmental impact assessment of pyrolysis of photovoltaic panels
A detailed analysis of the gases evolved during pyrolysis of the End-of-Life (EOL) crystalline silicon photovoltaic (c-Si PV) solar module, focusing on recycling strategies has been reported herein. Further the re ycled glass may re-use for fabrication/lamination sses, which poses challenges to the application of LCA methodology. PV modules encapsulated with Ethylene-vinyl acetate (EVA) – with and without Poly-vinylidene. . Several ecological challenges are associated with their inappropriate disposal due to the presence of hazardous heavy metals (HMs). It is estimated that by 2050, there will be approximately 60−78 million tonnes of PV waste (Farrell, C. ; Osman. . The rapid advancement in renewable energy sources has significantly increased the demand for solar photovoltaic panels, which play a significant role in achieving sustainable energy goals. However, this growing deployment of solar technology presents a dual challenge, managing end-of-life solar PV. .

Pyrolysis photovoltaic panels
Pyrolysis is a thermal decomposition process conducted in the absence of oxygen. It heats solar panels to high temperatures (typically between 400°C to 600°C), which breaks down the polymer layers, such as EVA (ethylene vinyl acetate), without burning them. . In the past few decades, the solar energy market has increased significantly, with an increasing number of photovoltaic (PV) modules being deployed around the world each year. Once they reach the end of their lifecycle, it becomes crucial to recycle them efficiently. Efficient recycling is essential for both environmental sustainability and resource recovery. PV modules encapsulated with Ethylene-vinyl acetate (EVA) – with and without Poly-vinylidene. . With the continuous advancement of recycling technologies for end-of-life solar photovoltaic modules, SUNY GROUP's fully automated PV module pyrolysis recycling line (Pyrolysis Recycling Line 2025 Edition) achieves industry-leading 99% material purity recovery through the integration of intelligent. .
