According to GBCSA estimates, the global construction sector accounts for nearly 40% of energy-related CO2 emissions, which makes it the most energy-intensive and biggest greenhouse gas-emitting industry in the world.
Responding to the demand for innovative solutions with a lighter impact on the environment is JSE-listed building material company Afrimat. Its CLC building and plaster lime offers a less carbon-intensive alternative that replaces cement as a binding agent in mortar and plaster.
While standard cement materials typically require higher burning temperatures during production, CLC lime absorbs about 75% of burned-off CO2 during manufacturing and, in fact, requires CO2 during drying. This process results in a weather-resistant carbonate stone that has a low embodied carbon footprint. It retains its breathability – limiting the damage caused by moisture and, as a result, proving more cost-effective and lower maintenance than cement.
In addition to providing the SA building sector with alternative construction materials, Afrimat consistently tracks and assesses its carbon footprint with the aim of reducing its environmental impact.
The company also provides employees with environmental-risk mitigation training, and it implements ongoing energy-reduction measures at its quarries and plants.
