Pollution Prevention
UMC’s environmental protection policy explicitly sets the goal
of zero pollution and the mandate to comply with or exceed
environmental regulation requirements or international
standards, in an attempt to become a sustainable green
enterprise. UMC has installed various effective pollution control
equipment and a 24-hour central monitoring system. It continues
to conduct annual pollutant tests and builds a dedicated
pollution prevention team pursuant to applicable regulations.
The team is in charge of pollution management and monitoring
to ensure the proper functioning and performance compliance
of all pollution control equipment.
Management Focus in 2011
● Acute Biological Toxicity in Waste Water
Due to the increased awareness of environmental issues and
the enforcement of government regulations, the control of
biological toxicity in effluent water has become a new area of
concern. UMC's pursuit of sustainability motivates it to join
Hi-tech Waste Water Discharge Standards Functional Group
made up by Hsinchu Science Park Administration, various
industrial associations, and Science Park Association. The group
members have conducted evaluations on factors that could
contribute to acute biological toxicity, including NH 3 , TMAH,
H 2 O 2 , electricity conductivity, nano or other substances. UMC’s
main task is to conduct an improvement assessment of TMAH,
which is scheduled to finish in 2011. The results will be sent to
Science Park Administration and Functional Group to facilitate
appropriate control measures. UMC has built a task force to
minimize the acute biological toxicity in waste water. The task
force focuses on raw materials, pipe diversion, and end-ofpipe
treatment technology. Its effort includes identifying the
toxicity profiles for raw materials, purchasing water quality
testers, identifying sources of waste water toxicity, setting up
a laboratory for daphnia toxicity tests, conducting an analysis
for key factors of biological acute toxicity and a toxicity test on
effluent water, and evaluating the treatment equipment for
biological acute toxicity key factors.
●Waste Contractor Audit Plan
All of UMC’s waste is outsourced for treatment by contractors.
In addition to selecting a qualified contractor and best
treatment method, UMC also established an annual audit plan
for its waste contractors and conducts regular audits in the
treatment plant.
