asphalt plants reduce emissions

RESTRICTIONS ON ASPHALT PLANTS

Cook asked Sen. Daily, who introduced the bill, whether the moratorium would reduce emissions from the states 37 operating asphalt plants. Daily said it would not reduce emissions, but would prevent increased emissions, particularly in Bridgeport, Colchester and Waterbury.

Increased use of reclaimed asphalt, reduced emissions

Reducing emissions and increasing the use of reclaimed asphalt pavement is among the key aims of plant manufacturers. Patrick Smith reports. Lower emissions and the use of recycled materials coupled with reduced costs are the aims of manufacturers of modern asphalt plants.
