Tightening the monitoring of NOx emissions from boilers
at the Daejeon Plant
As we consider the environment as a precious resource to be

NOx, which generates particulate matters (PM), is also an air
safeguarded and cherished for our future generations, we
strive to minimize our environmental footprint across the whole
of all our business operations. Building upon our sustained
environmental investments, we diversify our actions to reduce
waste, increase recycling, reduce the emission of air pollutants,
and tighten the management of environmental facilities.
Reducing the generation of waste and increasing recycling
level. At Hankook Tire & Technology, work is underway across
diverse areas to reduce waste generation. Our Chongqing
Plant performed independent research and on-site analyses
to promote the circulation and reuse of resources to lower the
generation of waste oil (hazardous waste) such as dust seal oil
and hydraulic oil, regularly used by its facilities to become an
eco-friendly plant. To achieve this, we refined the oil by diluting
it with newly-purchased oil and performed on-going quality
testing to gradually reduce waste oil generation and cut costs,
using resources in an eco-friendly way and demonstrating our
capability to be truly eco-friendly.

committed to minimizing resource consumption and waste
generation and to facilitating resource circulation so that
resources are reused multiple times. One such example is our
self-developed hybrid PE-film, of which up to 80% of it is made
from recycled polyethylene, a subsidiary material used to store
semi-finished tires. This hybrid film is currently used at our
Daejeon and Geumsan Plants, and we plan to gradually extend
its application to our global plants.

made to curb its emissions. In particular, industrial boilers rank just
second to vehicles in generating NOx emissions. Our Daejeon
Plant replaced its low NOx burners with ultra-low NOx burners
that are even more efficient. In addition, the Tele-Metering
System or TMS was deployed to monitor NOx concentrations
in real-time to monitor and prevent PM generation around the
plant vicinities.
