CEMENT RAW MATERIALS - International Cement Review

The UK cement industry has agreed to reduce its primary energy consumption by 25.6% per tonne of cement produced by 2010, from a 1990 baseline. In return, the industry receives an 80% rebate from the Climate Change Levy. The reductions are phased over a number of years (Table 2.2.1) MINERAL PROFILE: CEMENT RAW MATERIALS 2: Extraction and processing
