Implementing ISO 50001 at our Cement Division
In May 2016, we achieved full ISO 50001:2011
certification at our Clinker plant in Mambong. We also
commenced the ISO 50001:2011 implementation
process in our Pending grinding plant in 2017 and will
follow suit with our Bintulu grinding plant in 2018.
Specifically, ISO 50001 provides a framework to:
database for the system has been established and we
will call upon Standard and Industrial Research Institute
of Malaysia (SIRIM) energy auditors to vet through all
the required information. The implementation of ISO
50001 certification will commence in Bintulu in 2018.
In preparing the data relating to the system such as
electrical energy usage and mill output optimisation, the
relevant data has been collated from 2014 onwards.
Although the initiative is still fairly new, the committee
has to date several projects with 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 a Direct Current
(DC) motor to an Alternating Current (AC) motor which
contributed direct savings of almost 30 kW per hour. The
Division is planning to apply for an energy management
grant which will enable it to be appointed as an Energy
Audit Company registered with the Energy Commission
(Suruhanjaya Tenaga Malaysia).
Improving Energy Efficiency at the Cement Division
Through various initiatives introduced, the Group’s
Cement Division has been able to curtail its rate of power
consumption. Though the Bintulu grinding plant is still
in the preparatory stage for ISO 50001 certification,
owing to the recent throughput optimisations and higher
cement sales volume, the plant was able to reduce its
specific power consumption from 43.38 kilowatt hours
per tonne (kWh/t) to 40.89 kWh/t in 2017, a reduction
of 2.49 kWh/t.
The Pending grinding plant’s power consumption in 2017
was 34.51 kWh/t - down from 35.01 kWh/t in 2016,
a reduction of 0.5 kWh/t.
At CMS Cement Industries Sdn Bhd
(formerly known as
CMS Clinker Sdn Bhd)
or the Mambong grinding plant, the
specific power consumption in 2017 was 43.81 kWh/t,
down from 45.21 kWh/t in 2016, a saving of 1.4 kWh/t.
At the CMS Cement Industries’ kiln (clinker plant) the
specific power consumption in 2017 was 97.63 kWh/t,
down from 97.75 kWh/t in 2016, a reduction of 0.12
kWh/t.
The Cement Division continues to explore all avenues
to further improve kiln line availability, reliability
and performance factors in order to reduce its power
consumption rate.
Environment
As part of its efforts to adapt to the new initiative, our
Cement Division has 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 of the Division’s
Chief Executive Officer (acting as advisor), the General
Manager of Production and respective plant managers as
management representatives. It also includes engineers,
energy managers and other positions of influence in
order to ensure the success of this new strategy within
the Division.
The ISO 50001 committee for Pending grinding
plant has established the required framework for the
monitoring of electrical energy usage, the significant
energy usage circuit and the database for the committee
to work on. The relevant documents have been issued.
The committee has attended the required training
and meetings are conducted on a quarterly basis. The
The Mambong
