Coal Combustion

Paul Breeze, in CoalFired Generation, 2015. Coal combustion is a dirty process, releasing a range of pollutants including sulphur dioxide, nitrogen oxides, carbon dioxide, volatile organic compounds, ash and a range of heavy metals. If these are not controlled they can enter the atmosphere, causing damage to the environment and to human health. Air quality standards limit the amount of each ...

Cement

 · The direct CO2 intensity of cement production increased % per year during 201418. To get on track with the SDS, a % annual decline is necessary to 2030. Sharper focus is needed in two key areas: reducing the clinkertocement ratio (including through greater uptake of blended cements) and deploying innovative technologies (including CCUS).
