The Main Application Of Antimony
Antimony is used as a clarifying agent in photovoltaic glass, which can improve energy efficiency by about 10-20% and prevent the generation of bubbles. Solar glass typically contains
However, the composition of solar glass varies, especially concerning antimony (Sb) content, depending on the production method. Antimony is used to enhance the performance of patterned solar glass but introduces environmental and health concerns, complicating recycling efforts.
This makes recycling solar glass with antimony both costly and technically challenging. Transporting glass cullets (crushed glass ready for recycling) also presents a logistical challenge, as their low density makes transport costly and inefficient. What is the regulatory support for solar glass recycling?
The U.S. could also implement a threshold for antimony levels in solar glass, gradually reducing the allowable amount over time. This would encourage manufacturers to phase out the use of antimony in their production processes and facilitate more straightforward recycling in U.S. facilities.
Antimony-containing glass can lead to undesirable interactions with the manufacturing process, affecting quality and emissions.

Glass accounts for a significant propor on of PV module weight, making glass recycling an environmentally beneficial process due to reduced CO2 emissions and energy savings. However, the
Given that glass constitutes a substantial portion of PV module weight, recycling glass proves environmentally beneficial by reducing CO
Is antimony necessary for photovoltaic glass Guide for Ensuring Solar Glass Recycling Happens for Your PV The recycling of solar glass presents unique challenges, particularly due to the use of
The same study also reported that antimony trioxide leaches from solar glass after prolonged contact with water and subsequently undergoes hydrolysis, forming the antimony oxo
On top of supply risk, antimony trioxide carries a health warning label. It has been classified as a carcinogen in recent toxicology assessments, and regulators are increasingly
Given that glass constitutes a substantial portion of PV module weight, recycling glass proves environmentally beneficial by reducing CO 2 emissions and conserving energy. However, the
This article explores a new process for extracting valuable antimony from the glass of solar panels, aimed at solving disposal challenges in the 2030s.
At that time, dispensation was granted to optical glass and solar glass because the European industry had then represented that it was not possible to make solar products without it. However, glass
A significant portion of framed silicon-based solar panel waste is glass, approximately 67-76%. Ensuring effective recycling of this glass is not only crucial for minimizing the environmental
The proposed PhD thesis is part of the ANR GRISBI project (2026–2030), which aims to optimize the recycling of glass from photovoltaic (PV) panels. These glasses, predominantly manufactured in
