A Concrete Energy Efficiency Solution

Cement , the key ingredient of concrete,is the world’s most widely used building material. It’s also the product of an energy-intensive process that accounts for about 5% of global greenhouse gases. These emissions threaten to increase as developing countries urbanize and build roads, buildings, and other infrastructure in the decades ahead. 

To pursue a low carbon growth path, the industry needs to adopt the most efficient technologies including waste-heat recovery (WHR). Waste-heat recovery involves capturing the excess heat of an industrial process and using it to generate electric power. The technology can be used in a number of heavy industries, including steel and chemicals, but has not been applied extensively outside of China despite its potential to increase energy efficiency and mitigate climate change.
