About ShellCem

Oyster Shell Contains 92 % of calcium carbonate.

Based on its mineral properties, oyster shell is a suitable alternative to replace limestone in cement manufacturing as one of the raw materials.

Project Approach

ShellCem Project employs an "All People Engagement" approach to enhance the recycling process. This means not only one party or organization is responsible for waste handing, but also all communities and individuals who contribute for the waste generation and circular economy.
