Note 1 The statistics of Taiwan Glass's wastewater volume are presented by the number of emissions paid by each factory. The
emissions of Taichung processing factory include Taiwan Autoglass Ind. Corp., and the emissions of Changpin factory include TG
TECO Vacuum Insulated Glass Corporation.

Note 2 Taichung factory and Taichung processing factory reuse wastewater for cleaning filter cloths and flushing roads, so the payment
measurement is lower than the actual discharge.

All factories have wastewater treatment equipment to reduce the pollutants in the wastewater so that the wastewater can meet the
local discharge quality standards. Domestic sewage, after being treated by the treatment system, is compliant with the legal standard to be
discharged to the surface water body. TGI factories discharged a total of 1,410,199tons of wastewater in 2019.
