Borosil has developed NoSbEra: World's first Antimony-free solar glass.- The world is staring at a burning issue of the most hazardous substance "Antimony" present in solar glass.
- Antimony in solar glass is toxic and causes :
Skin and respiratory problems.- Interferes with gastro-intestinal functions.
- Causes chromosomal damage in leucocytes, inhibits healthy reproduction.
- Possibly carcinogenic to humans.
- Limits set by various agencies on Antimony in drinking water :
- US Environment Protection Agency (EPA).
- 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.
- The Antimony from crushed glass leaches out and gets mixed with water and enters the soil which affects the seed germination process.
- The problem posed by a solar glass containing Antimony is of GIGANTIC proportions :
- By 2030 the estimated proportion of solar glass as a percentage of total panel mass for different PV panel technologies C-Si (80%), CIGS (90%), CdTe (95%).
- The Estimated cumulative solar glass waste will be 1.5-7 Million tonnes by 2030. This leads to an exposure of 3000-20000 tons of Antimony.
- Borosil has been able to successfully remove the Antimony from Solar glass.
- Institut fur Solartechnik SPF, SWITZERLAND, widely considered a GOLD STANDARD for testing and certification of solar glass publishes on its website, test results of solar glass from some of the top solar glass manufacturers in the world.
- Test results published by SPF establish that Antimony free glass by Borosil has nil photo-degradation and the highest efficiency amongst the solar glasses.
