IW EPD GWP: Ready mixed producers shrink carbon footprint by one-fifth

National Ready Mixed Concrete Association producer members have lowered their carbon footprint by 21 percent in seven years, according to a new Life Cycle Assessment (LCA) report and Industry Wide Environmental Product Declaration (IW EPD). NRMCA has tracked environmental impacts—carbon dioxide emissions, energy and water use, and waste associated with ready mixed concrete production activities—since releasing an inaugural LCA in…

Calculator performs life cycle assessment for slag cement concrete

IMAGE

The Slag Cement Association has programmed a calculator with which concrete producers can quantify and interpret cradle-to-gate life cycle assessments (LCA) reflecting the environmental impact of mixtures with and without slag cement. Calculations are based on the industry-average Environmental Product Declaration (EPD) for ready mixed concrete that incorporates industry-average EPDs for slag cement and portland cement in the United States. The calculator also allows users to evaluate how different concrete mixtures affect whole building impacts based on a typical case study project.

NRMCA caps first phase of industry-wide Environmental Product Declaration

A representative sampling of energy consumption trends from a coast-to-coast, cross section of producers contributes to the NRMCA LCI Data Collection Summary Statistics, boosting the credibility of an industry-wide EPD for transit or central mixed concrete.

The first of two phases in the National Ready Mixed Concrete Association’s development of a standard Environmental Product Declaration (EPD)—aimed at assisting ready mixed producers on projects where customers target certification under the new LEED v4 green building rating system—has produced a survey report and list of participating companies and plants.
