NRMCA has become an Environmental Product Declaration (EPD) Program Operator, a designation enabling it to help members meet new requirements in LEED v4, International Green Construction Code (IgCC) and the Architecture 2030 Challenge for Products. EPDs are third-party verified reports published by product manufacturers that provide quality assured and comparable information regarding the environmental performance of their product.

A major coal producer has acquired a 10.3 percent position in Alexandria, Va.-based Ceratech Inc., whose Ekkomaxx technology can yield concrete binding agents with performance characteristics reportedly matching ASTM C150 Types I–V powder.
Alpha Natural Resources can increase its Ceratech stake to 28.3 percent under certain future terms. It becomes the second coal producer to invest in prospective concrete technology offsetting carbon dioxide emissions from either portland cement production or fossil fuel-fired power generation. In April 2010, market leader Peabody Energy took a $15 million interest in Calera Corp., whose calcium carbonate precipitation processes—applied to power plants’ flue gas streams—are netting concrete-grade fine aggregate.
