It is well known that the production of cement will release a very significant amount of carbon dioxide (CO2) into environment. As a rule of thumb, for every ton of cement product, an equivalent amount of carbon dioxide (CO2) will be released into the atmosphere. Of course, this CO2 comes from various stages of cement production process, starting from extraction of raw material till the delivery of the cement. However, the majority of the carbon dioxide (CO2) is released during the process of transforming limestone into clinkers.<br />
<br />
Many developed countries have taken many constructive steps in talking this issue, either due to economic reason or regulative requirement. Therefore, it is time for Malaysian cement manufacturers to look into ways to cut down the carbon dioxide (CO2) emission. The most common way of reducing the carbon dioxide (CO2) emission is by replacing part of the cement clinkers with other supplementary cementitious material, which is normally a by-product of other industries. Currently, Fly-ash and slag has been used widely as replacement material in cement manufacturing. Replacing the cement clinkers with either one these materials will reduce the carbon dioxide (CO2) emission significantly.<br />
<br />
Fly ash is a by-product of coal fueled power plant, while slag is a by-product of steel industry. Both these materials have been researched extensively and their benefits in concrete have been published and debated in thousands of publications and conferences. For every part of cement replaced by this material, there will be an equal amount of reduction in carbon dioxide (CO2) emission.<br />
<br />
Besides the CO2 reduction, the use of by-products will also enhance the durability of concrete which will result in better life span for the structure. The use of by-products also reduces the heat of hydration thereby results in reduced thermal cracking, and also many other problem. The use by-products in concrete especially the slag has been proven to improve the durability of marine structures exposed to chloride and sulfate attack.<br />
Governments of many developed countries have made it mandatory for the cement manufacturers and users to use recycle by-products in cement and construction. It is time for Malaysian government and industry players to come together to play an important role in promoting the use of by-products in cement production as well as in overall construction process. There has been some initiatives taken by some manufacturers, but the green journey has just begun, and we hope to see more initiatives coming up.<br />

We should do this especially as we are custodians for future generations.<br />
</div><div style="text-align: justify;">New Malaysian initiatives unveiled recently leave me feeling ever optimistic that we are doing more to preserve what we have, in order that our children and their children may enjoy our unique, natural wonders for years to come.<br />
</div><a name='more'></a><br />
<div style="text-align: justify;">Firstly, under <a href="http://www.pmo.gov.my/bajet2010.php" target="_blank">Budget 2010</a>, a fund amounting to RM1.5 billion will be established by the Government to provide soft loans to companies supplying and utilising green technology. The Government is furthermore committed to restructuring the Malaysia Energy Centre as the National Green Technology Centre; organising an international exhibition on green technology next year; developing Putrajaya and Cyberjaya as pioneer townships in green technology; and giving priority to environmentally-friendly products and services.<br />
</div><div style="text-align: justify;">Another initiative sees the Sabah state government partnering with WWF-Malaysia to conserve large tracts of forest to protect the habitat of endangered orangutans. The area targeted for restoration amounts to nearly 1,500 football pitches in size.<br />
</div><div style="text-align: justify;">Thirdly, there is the National Tiger Action Plan, adopted by the National Biodiversity-Biotechnology Council. The plan targets an increase in Malaysia’s tiger population from fewer than 500 to 1,000 by 2020. The setting up of a National Biodiversity Centre was also agreed, to further strengthen the management and conservation of biodiversity in Malaysia.<br />
</div><div style="text-align: justify;">We should not stop at these measures. I would like to obtain your views on what more we can do to ensure a greener Malaysia, so that we can learn from each other. How are you reducing your carbon footprint? Please share your thoughts by submitting a comment.
