Cement industry in China
The cement industry in China is the largest in the world, producing 2462 Mt in 2014, an annual increase of 2.6%. China roughly yields 60% of global production of cement. In 2017 China produced 2,400,000 metric tons of cement where as other countries produce cement about 1,728,300 metric tons of cement.
Producing large amounts of cement also causes several problems such as producing one ton of cement emits one ton of carbon dioxide. To heat a cement kiln with waste requires about three times as much waste as coal, and can reduce emissions by around 10%, according to engineering company FLSmidth. Apart from this, the Chinese cement industry has already made improvements in energy efficiency. In 2017, it accounted for 57% of the global industry's output but only 52% of its emissions. However, emissions reductions from energy efficiency measures are tiny compared to those that could be achieved with innovative technologies such as carbon capture and storage, which sequesters emissions.
