Today the world population stands at 7.6 billion. It will rise to 9.7 billion by 2050. About 2.5 billion people are expected to live in cities. This results in growth of urbanization thereby increasing the demand for solid urban infrastructure. These changes in world population will directly impact the production requirements placed on the cement industry. More people as a result of rising population need more cement causing increased CO2 emission, producing higher and higher pollution, creating growing risk to health creating growing risk to healthy living and so on. Global cement demand is set to grow 12-23 per cent by 2050. To achieve these global emissions targets of CO2, and the required energy reduction in cement production, new policies and investments are needed. The two most important challenges facing the industry are a pressing need to reduce CO2 emissions and improve energy efficiency. It involves the use of low carbon fuels and energy reduction methods. The use of other fossil fuels such as biomass, on the other hand, can be an effective fuel substitute, producing CO2 emissions that are about 20–25% less than those of coal. Every ton of ordinary Portland cement that is produced releases on average a similar amount of CO2 into the atmosphere. Improved production methods and formulations that reduce or eliminate CO2 emissions from the cement manufacturing process are thus high in demand.
