Ground calcium carbonate, commonly referred to as GCC, is primarily based on limestone and chalk in the UK, though marble stone is imported and processed at a few locations. Precipitated Calcium Carbonate (PCC) is produced through a recarbonisation process or as a by-product of some bulk chemical processes.

Researchers in the UK have developed a process that could drastically cut the carbon emissions associated with manufacturing cement. The low-temperature process produces both calcium hydroxide and sodium carbonate, and carbon dioxide that would otherwise be released gets stored as a stable and useful mineral. Limestone decarbonisation, a major process required for cement production, is

Manufacturing Process Calcium carbonate is often made into chalk or limestone, but is also the main ingredient in Tums. This compound is a raw material, and is also the most commonly found organic compound. It can be found in many places, for example: rocks, caves, and even sea shells! Although calcium carbonate can be used as chalk, it can also be used in edible items.
