Clinker is mixed with gypsum and ground to a fine powder to make cement. Coal is used as an energy source in cement production. Large amounts of energy are required to produce cement. It takes about 200 kg of coal to produce one tonne of cement and about 300-400 kg of cement is needed to produce one cubic metre of concrete.

J.M. Khatib, in Sustainability of Construction Materials (Second Edition), 2016. Chapter 25 concludes that, because of an increase in demand, gypsum mining will also increase. However, demand will force the construction industry to use more synthetic, waste and recycled gypsum. In Europe, it is anticipated that by 2035, 25% of recycled gypsum will be used.
