In the latest stage of the project, the Company recently
completed a preliminary trial burn and stabilisation test
at Mambong Integrated plant on silicon manganese
furnace slag road base from OM Sarawak (Malaysia) Sdn
Bhd and Pertama Ferroalloys Sdn Bhd. Laboratory test
results to determine its suitability as supplementary
material for subbase, roadbase and CIPR were
convincing and are submitted in an application to the
DOE in Sarawak which is now awaiting approval. CMS
Pavement Tech is also currently running a field trial on
the pavement after which post construction monitoring
will be carried out.
Other uses for the slag waste such as in Ready-Mix
Concrete, Premix, etc., are being undertaken by the
respective Divisions and companies within the Group.
Although the waste will not be entirely free to us, it
would be much better to use this waste material as
road base, if possible because there is not much hard
stone available in northern Sarawak. Even in the south,
granite-type stone is in limited supply. The more we can
recycle, the better we can help create a modern and
environmentally-friendly society and at the same time,
continue the economic development of the State.
Cold in Place Recycling (CIPR)
CMS Pavement Tech Sdn Bhd is a specialist provider of
pavement works covering construction, rehabilitation
and maintenance. As the conventional method of
pavement rehabilitation tends to be costly, inefficient,
slow and environmentally-unfriendly, CMS Pavement
Tech specialises in using cement stabilisation technology
to reconstruct while rehabilitating pavements using
the Wirtgen WR2500S machine. In this new method,
existing pavements are recycled, stabilised with cement
and enhanced with a higher strength, new bounded base.
This subsidiary is also capable of performing stabilisation
works using other agents such as lime, emulsion,
bitumen and soil stabilisers. As an environmentally-
friendly company, CMS Pavement Tech promotes
sustainable engineering and construction using
locally-sourced, alternative materials. By tapping the
Company’s technology, clients can take advantage
of cost savings, quicker construction times, as well as
improved pavement performance and design life.
In 2017, the total amount of recycling-in-place that
the Company conducted amounted to 184,300 metric
tonnes. The total length of off-site milling conducted
during the year was 6km.
WASTE MANAGEMENT
The Group’s commitment to sustainable and ethical
practices encompasses all our operations including our
waste management practices. Here at CMS, we take the
practice of collecting and disposing of waste and effluent
produced in our plants very seriously. Improper waste
management can potentially have a negative effect on the
community’s health and similarly it can also negatively
impact the environment. Positive waste management
systems, however, can avoid the negative impact that
waste has on the environment. As a responsible industry
player, CMS is committed to finding innovative and
environmentally-friendly ways to re-utilise waste, as well
as to dispose of it.
In 2017,
CMS Wires Sdn
Bhd recycled
23.80 tonnes
of scrap iron
and iron oxide.
In 2017, the
total amount
of recycling-in-
place that CMS
