Prospect of CO2 sequestration in Malaysia cement industry

Abstract

Carbon Dioxide (CO2), a known greenhouse gas, is the most influential driver of climate change. Tolerable amounts of CO2 emission are naturally produced through respiration, volcanic eruption, and organic matter decompositions. However, excessive emission of CO2 by human activities such as deforestation, changes in land use, construction, and energy-generating processes eventually increases the earth's temperature and results in irreversible global climate change. In line with the Paris Agreement's aim to limit the impact of climate change, numerous research is undertaken globally to identify ways to reduce man-made CO2 emissions. This paper discusses several potential CO2 sequestrations through CO2 utilization in the cement industry and their applicability for adoption in Malaysia as part of carbon emission reduction; fresh concrete, masonry bricks, cement bonded fibreboard, recycled masonry aggregate, recycled concrete aggregate and ultra-high performance concrete.
