Implementing ISO 50001 at our Cement Division
InMay 2016,we achieved full ISO50001:2011 certification
at our Clinker plant, thus completing the process which
we had begun in the previous year. We also commenced
with the implementation process in our Kuching plant
during the year and will follow suit with our Bintulu plant
in 2017.
Specifically, ISO 50001 provides a framework to:
• Develop a policy for more efficient use of energy;
• Set targets and objectives to meet the policy;
• Use data to better understand and make decisions
about energy use;
• Measure the results;
• Review how well the policy works; and
• Continually improve energy management.
As part of its efforts to adapt to the new initiative, our
Cement Division set up a committee to specifically
monitor the implementation of ISO 50001 and to ensure
its success within the Division’s respective companies.
The committee members comprise the Division’s
Executive Director/Chief Executive Officer acting as
advisor, General Manager of Production and respective
Plant Managers as management representatives. It also
includes Engineers who have been appointed as energy
managers and other Engineers or Managers who have
strong say and enough influence to ensure the success of
this new strategy within the Cement Division.
Although the initiative is still fairly new, the committee
has to date rolled out several projects with several basic
energy-reduction awareness plans in the pipeline. One
of the projects that was successfully implemented was
the conversion of a cooler second grate drive from DC
motor to AC motor which contributed direct savings of
almost 30 kW per hour (kWh). The Division will apply for
an energy management grant in 2017 which will enable it
to be appointed as an Energy Audit Company registered
with the Energy Commission or Suruhanjaya Tenaga
Malaysia.
Introducing Energy Efficient Technologies
CMS Cement Sdn Bhd aims to minimise overall energy
consumption and to maintain grinding efficiency. The
Company has been using the SIKA 874, a pre-grinding
processing aid since 2011 to improve grinding efficiency
at its Kuching plant. This has helped to reduce the plant’s
power consumption from 42 kWh/MT to 34 kWh/MT.
Over time the use of SIKA 874 as a grinding aid and
strength enhancer to the cement during the cement
milling stage has increased both throughput and cement
strength from 5% to 10%. This is equivalent to 300 kWh
savings per tonne of cement produced. In 2016, the
usage of SIKA 874 was put under strict control to reduce
operating costs due to lower cement demand and
improved produced clinker quality.
Back in 2015, CMS Clinker Sdn Bhd upgraded its kiln and
began to use a high-momentum burner that controls the
swirl and jet air volume for a more effective flame shape.
A cooler efficiency study executed in 2016 showed that
heat recuperation from the cooler was well above 80%
after the upgrading exercise. Heat consumption for 2016
was also above 800 kcal/kg due to the lower production
output caused by several external and internal factors.
This marked a significant increase from the previous year
which measured heat recuperation and consumption
below 800 kcal/kg.
Energy Efficient Lighting
As part of our efforts to decrease the negative effect of
toxic chemicals in the environment while minimising
our operational costs, many of our companies have
been converting to energy-efficient lighting. LED bulbs
have proved to be the most feasible option as they are
energy efficient, have a long lifespan and are free of toxic
chemicals.
CMS’ Property Development Division is using LED lighting
in the common areas of many of its new properties such
as the niche Rivervale Residences project and The Isthmus
river pontoon. The Division also uses LED bulbs in its
general landscaping lighting and sodium lamps (which
reduces energy) at its construction sites. The year saw
an addition of 47 solar lights introduced at the Rivervale
Residences.
CMS Cement Sdn Bhd has also adopted the practice of
using LED lights. The Company has implemented LED
lighting at its Kuching plant and has begun to run the
cement mill during off peak hours due to low cement
demand. The plant also strictly controls the starting of
the 6kV motor, choosing to kick-start the motor after a
30-minute lapse from the previous tripping or stoppage,
following the plant’s conversion of motors from DC to AC
power.
Samalaju Properties Sdn Bhd installed two units of solar
lighting at the Eco Park Sales Gallery/Site Office in 2014.
The 40W LED lanterns have since been saving the office
with RM35/unit per annum on electricity bills.
Our efforts in implementing energy-efficient lighting
extend beyond the changing of light bulbs, as is evident
at our Samalaju Resort Hotel which was built with a green
concept in mind. The architecture of the building employs
substantial amounts of tempered glass panels to allow
indirect natural lighting into the premises. The hotel site
was also deliberately designed to face the South China
Sea, to allow the wind from the sea to naturally cool the
premises and to reduce the solar heat. To facilitate long
lifespan term savings, energy-efficient lightings have
been planned for the hotel from the onset. The usage of
LED lightings have translated into an estimated 50% cost
savings to light up the hotel as compared to conventional
lighting.
