· Type 1L was conceived as a way to limit the amount of CO 2 generated because cement is basically limestone put in a kiln and cooked. It’s cooked until it turns into little boulders called clinkers, and then they grind it. When that comes out of the bottom of the grinder, it’s called cement.”.

Cement plants are highly capital intensive. The construction of new plant costs about £10 million for each 100 000 tonnes per year of cement capacity. Large modern plants can, therefore, cost over £100 million. Ongoing capital investment at individual plants can also typically amount to several million pounds a year.
