technologies, and skills. Circulation activities maximize the value of environmental
knowledge which is also the purpose of EKM. According to IISI [42], CSC had be-
come the world's seventeenth largest (and Asia's eighth-largest) steel making group
by 2000. In addition, CSC was listed in a list on Forbes [43] as one of the 400 best
large companies of the world. Moreover, CSC was designated by IISI as 25th out of 80
top steel producing companies in 2006 [42] which demonstrates the performance and
implementation of EKM in CSC.
From the interviews conducted in this study, it is clear that CSC uses environmental
knowledge activities to its advantage and continuously creates, accumulates, shares,
utilizes, and internalizes environmental knowledge enabling EKM to mesh with CSC's
ethos, mission and vision (Figure 2). External stresses such as environmental policies,
WEEE, RoHS, awareness of the environment, green innovation, and social responsibil-
ity all speed up the improvement of EKM in CSC. Moreover, in consistently improv-
ing with EKM activities, environmental knowledge is internalized CSC business spirit,
organizational values, competitive advantage, and organizational culture which drive
CSC to use its environmental knowledge and ideas in product design and the produc-
tion process. Therefore, CSC has built up a complete and high quality EMS through the
EKCP providing a good example for other enterprises to follow.
Environmental Performance
According to the environmental load of Chinese Steel Corporation, this report will be
referred to the environmental load generated in 2004, including input of resources and
energy, as well as gas, liquid and solid output. This report indicates the current status
along with improvement measures taken in the past years.
Indicators are calculated based on each ton of steel products, including:
• Unit consumption of energy and discharge of CO
2
gas.
• Unit discharge of NO
2
, SO
2
and particulates from waste gases.
• Unit consumption of water and unit discharge of chemical oxygen demand
(COD) and suspended solids (SS) in effluent.
• Generation of the by-products process and the recycled or disposed percentages.
Therefore, environmental performance really can be improved through the per-
formance of EKM.
In response to environmental regulations and increasing of environmental aware-
ness, CSC implemented environmental technology and managed solutions to reduce
emissions and natural resource demands and control waste. For instance, water treat-
ment has been a major concern; it includes physical, chemical and biological treatment
to remove or change the composition of coke effl uent before releasing or recycling.
The water recirculation system ensures water effi ciency and enables reuse of water to
reduce production costs. The CSC is still searching for new environmental knowledge
to reduce the environmental pollution, energy demand and manufacturing cost via the
newest recycling technologies.
Water Pollution Control and Water Consumption
The CSC method of water pollution control and consumption is an in-plant process
that reduces and eliminates the generation of pollutants and waste to reduce risk to
