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).

What are the types of coal?
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalifiion," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are:

· The type of fuel and efficiency of equipment used during clinker production also have an impact. Meanwhile, the floor area of the world's buildings is projected to double in the next 40 years. This means cement production is set to grow to around 5bn tonnes by 2030, a 25% increase from today, reaching over four times 1990 levels.

Coal – Types, Uses and Formation
In this process, mineworkers have to remove all kinds of rocks and soilforming the top layer. It is cheaper than underground coal mining. There are three types of surface mining strip mining, where explosives are used to remove the top layers; open pit mining when a pit is dug, and MTR mining where a whole mountain summit is destroyed.
