Lehigh Redding moves to mill SCM from CO2-rich kiln emissions

Lehigh Hanson Inc. and Fortera Inc., a Silicon Valley technology developer wise to calcium carbonate chemistry and mineralization, are teaming to commercialize a process with optimal output for an era of greenhouse gas scrutiny: Converting the carbon dioxide gas emitted to the environment at the front end, or calcining phase, of ASTM C150 powder production into a blendable supplementary cementitious…

CalPortland documents glaring greenhouse gas accounting void

Paper cropped

In a new paper summarizing peer-reviewed scientific studies, CalPortland Co. staff cites the exclusion of a critical factor in global, national, and regional greenhouse gas accounting methods: Concrete buildings, pavements and structures are silently absorbing carbon dioxide from the atmosphere—to such an apparent degree that the built environment represents one of the world’s largest carbon storehouses.

Cement companies inventory low-carbon production methods per Paris Accord

Sources: World Business Council for Sustainable Development (WBCSD), Geneva; CP staff

A new report from WBCSD’s Cement Sustainability Initiative (CSI) focuses on technology availability and the need to scale up research and development that can help the cement industry mitigate greenhouse gas emissions. In light of the United Nations Framework Convention on Climate Change Paris Agreement’s entry into force, CSI effected an in-depth review of its original papers from 2009, when the sector issued the first ever low-carbon technology roadmap in partnership with the International Energy Agency (IEA).

Cement production undeniably minor in EPA greenhouse gas emissions census

Sources: U.S. Environmental Protection Agency; CP staff

U.S. portland cement production accounted for 2.3 percent of carbon dioxide-equivalent (CO2e) emissions in EPA Greenhouse Gas Reporting Program 2015 data. Modern kilns increasingly running on natural gas and other coal alternatives, coupled with limited offsetting import factors, appear to position the domestic cement industry favorably in a business often tagged as the source of 5 percent of global carbon dioxide emissions.
