The bulk of Taiwan's SF6 emissions come from the optoelectronics, semiconductor, power generation, and magnesium industries. Since the EPA signed SF6 voluntary reduction memorandums with Taiwan's optoelectronics and semiconductor industry associations there has been an estimated reduction in emissions in carbon dioxide equivalent (CO2e) of24 million tonnes. As for the electricity generation industry, their emissions of SF6 come mainly from leakages arising from the insulation of high-voltage facilities. As a result, since 2006 the EPA has been actively promoting the recycling of SF6 from the electricity generation industry and in 2009 completed R&D into purification and reuse technology for this type of SF6. Testing has shown that when the water and impurities are removed and the waste SF6 is purified in the correct manner then it can be used directly by the magnesium industry, which is of great benefit in reducing Taiwan's emissions of this greenhouse gas. This article will introduce how to reduce SF6 cooperation between the electricity and Magnesium industries
