The use of silicones, siloxanes and silanes generates energy savings and greenhouse-gas emission reductions that outweigh the impacts of production and end-of-life disposal by a factor of 9.
The study was commissioned by the GSC from the sustainable development research firm Denkstatt in Austria, in association with Dekra, a German testing and certification company. Denkstatt and Dekra assessed the greenhouse-gas emissions and emission-reduction effects linked to the manufacturing, use and waste management of silicon-chemistry products in Europe, North America and Japan.
"The study found that Si-chemistry products in the three regions allow for net CO2 emission reductions of about 52 million tons per year."
This equals the emissions required to heat 10 million homes in the regions covered by the study – or three times the number of households in the Greater London area.
Also striking is that a relatively small quantity of silicone, siloxane or silane can lead to a comparatively large increase in the efficiency of processes and the use of energy and materials. Examples include high-performance thermal insulation products, foam-control agents for washing, paint additives that increase the durability of vehicles and construction materials, and silanes used to reduce the rolling resistance of tyres.
