The Concrete Reinforcing Steel Institute, Schaumburg, Ill., has released Environmental Product Declaration (EPD) for Fabricated Steel Reinforcement Bar, superseding a 2017 declaration. Aware of the increasing interest in transparent reporting of a construction product’s cradle-to-gate environmental performance, CRSI aims to demonstrate members’ sustainability leadership, underscored by their a) output of reinforcing bars of more than 97 percent recycled content, and…

U.S. DOT announces $7 million in grants to promote LCA, EPD adoption
The Federal Highway Administration has awarded $204,000-$312,000 grants to support sustainable pavement, materials emissions tracking and related initiatives at more than 20 state departments of transportation. Many of the initiatives are centered on developing, adopting or advancing the use of life cycle assessment (LCA) methods and environmental product declarations (EPD). The latter encompass LCA data and are the most widely…

The ACI Foundation Concrete Research Council will fund a record eight research projects this year, its budget buoyed by a one-time, $500,000 commitment the American Concrete Institute to address the industry’s growing need for such technical support. The projects are:
Read MoreCalculator performs life cycle assessment for slag cement concrete
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.
