▫️ The main raw material for producing cement is heated to very high temperatures achieved by burning of huge amounts of coal and fossil fuels.

▫️ In the complete process, carbon dioxide is released in two occasions.

1. Conversion of limestone to cement

2. Burning of biofuel and fossil fuel

▫️ The carbon emissions from the cement industry in Sri Lanka is seen below.

▫️ The main contributor of GHGs by cement production in Sri Lanka is the Puttlam Cement Company Limited (PCCL).

▫️ The following graph shows its release of carbon dioxide.

▫️ The next graph shows the predicted carbon emissions by PCCL.

SOLUTIONS

▫️ The most basic and strongest step to fight the GHG emissions would be to either use alternative raw material or change the ratios of raw material.

▫️ Additionally, sources of energy other than biofuels and fossil fuels can be considered.
