Factory Water Recycling and Conservation Measures

In order to cope with the extreme climate change and water shortage risks, TGI factories continued
promoting water conservation in 2017. In addition to improving facilities and equipment, TGI also
conducted outreach to staff on water use for behavioral changes to improve the efficiency of water
conservation. The Hsinchu Factory had a higher water recycle rate in 2017 than 2016 because the factory

introduced filtered pure water with high conductivity to the cooling circulating pool and increased the
conductivity standard of the cooling pool. This means the wastewater will not go to the wastewater pool
and as the result, the amount of wastewater had decreased while more water had been recycled, which
contributed to a higher recycling rate.
The following table shows each TGI factory§s amount of water recycled and recycling rate in 2017:
