Cement Kilns: A Ready Made Waste to Energy Solution

The need to move towards a circular economy has pushed both waste generators and the cement industry to optimise the whole value chain from waste to a resource. In a typical cement kiln some 200 tonnes per hour of sintering material passes the burner(s). The ashes of the fuel used to heat the kiln drops into the glowing material and reacts with

The generation of power from a cement kiln waste gases: a

According to 3, the efficiency of the steam turbine process is around 25–30%, meaning only a 1/4 of the waste heat is transformed into electrical energy in the cement industry. The thermal energy content of cooler waste gases was found to be 784 kJ/kg of clinker. However, only 435 kJ/kg of clinker can be utilized for power generation.

Cement's solution to plastic waste CEMBUREAU

However, there is still much work to be done. This is why the cement industry is championing the issue of protecting Europe's resources, including the innovative use of plastic waste. Currently, approximately 43% of thermal energy fuelling the clinkers used in European cement production comes from waste including plastics and biomass.

Environmental impact of concrete Wikipedia

Carbon dioxide emissions and climate change. The cement industry is one of the two largest producers of carbon dioxide (CO 2), creating up to 8% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel. The CO 2 produced for the manufacture of structural concrete (using ~14% cement) is estimated at 410 kg/m 3 (~180 kg/tonne @ density of 2
