Cemstone Chosen for Expansion of Project Green Fleet Program
Cemstone, Mendota Heights, Minn., an Upper Midwest provider of aggregates, decorative concrete and masonry products, has been selected by the Minnesota Environmental Initiative (MEI) and its Project Green Fleet program to upgrade 21 vehicles in its ready-mix concrete truck fleet.
When retrofitting is completed in January 2010, the vehicles will have diesel oxidation catalysts (DOC) or diesel multi-stage filters that are expected to reduce engine emissions by up to 50%.
