Necessity for recycling photovoltaic glass: Managing resource
The production of this significant amount of (77.1–178 Mt) glass annually will place considerable pressure on raw materials, such as antimony (Sb), which is essential for PV glass manufacturing.

NoSbEra Antimony Free Solar Glass
Proportion of Antimony in solar glass is typically 0.2% to 0.3% (2 to 3 million ppb). Each PV module has a front glass weighing about 16 kg and thus an Antimony content of 32 to 48 grams.

Request QuoteFAQs about Amount of antimony metal used in solar glass
How much antimony is in solar glass?
World Health Organization (WHO): A limit of 5 ppb. California Environmental Protection Agency (CalEPA): A public health goal of 1 ppb for Antimony. Proportion of Antimony in solar glass is typically 0.2% to 0.3% (2 to 3 million ppb). Each PV module has a front glass weighing about 16 kg and thus an Antimony content of 32 to 48 grams.
Can you recycle solar glass with antimony?
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?
How can the US reduce antimony levels in solar glass?
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.
Should PV module manufacturers be required to disclose antimony compounds?
To address these challenges, the ESIA Recommendation paper suggests that the European Union should consider mandating PV module manufacturers under the upcoming Ecodesign regulations to disclose the composition and manufacturing process of solar glass, including additives like antimony compounds.
