CO2 and Climate Change
Climate change is one of the pressing issues faced by the world today. It is caused by the increased concentration of greenhouse gases in the atmosphere, among which is carbon dioxide (CO2).
The cement industry is a contributor to CO2 emissions. In the process of cement manufacturing, CO2 emissions come from the decarbonation of raw materials and the combustion of fossil fuels.
As a Group, Lafarge has taken proactive approach in handling the issue of climate change by initiating the Cement Sustainability Initiative, a chapter under the World Business Council for Sustainable Development. Lafarge has also established a partnership with the World Wildlife Fund and has made a commitment to reduce its CO2 emission by 20% per tonne of cement over the period of 1990-2010.
How We Fulfil Our Commitment |

In order to reduce our emissions and fulfil our commitment, we have taken a three-pronged approach:
The sustainability of natural ecosystems comes from their equilibrium with optimum consumption of material and resources that are constantly recycled. Industrial ecology applies these principles to human activity, making the most efficient possible use of by-products and waste.
The recovery and reuse of by-products is a well-established practice in the cement industry. While Lafarge fully embraces this idea and uses waste of other industries as alternative fuels, we observe stringent criteria when it comes to using any waste material at any of our plants. The waste materials must:
At Lafarge Malayan Cement, our cement kilns are used for the disposal of various types of wastes, including scheduled wastes. It provides an economic advantage to the industries we serve as well as protecting the environment and conserving the non-renewable resources.
We have a team who is dedicated to deliver service and waste management solutions to a steadily growing range of industrial customers.
Should you have any enquiries on our Industrial Ecology services or you need a complimentary consultation on the disposal of your industrial waste, please contact:

CO2 and CementWhy does the manufacture of cement produce CO2?
Cement manufacturing is the source of 5% of global CO2 emissions. The cement industry is a natural producer of CO2:
Pulverised Fuel AshPulverised Fuel Ash (PFA) is hydrophilic and can be used as a cementitious additive. The ash, which is collected from chimney filters in coal-fired power plants, is composed of vitreous silica, alumina, iron oxide and lime. They can be used as a partial substitute for clinker and thus help to reduce CO2 emissions.
