Concrete & Asphalt Recycler Does Away with Dust

At the Spring Street Recycling plant, the Dust Boss DB-60 stops dust from infiltrating surrounding neighborhoods.

Residents of West Haven, Conn. feared that an asphalt and concrete recycling plant, built there in 2005, would cover their neighborhoods and surrounding areas in dust. But thanks to new dust-control technology, those residents are, for the most part, sneeze-free.

Spring Street Recycling recently began using the Dust Boss DB-60, a fully automatic high-pressure misting system to control the levels of dust produced by the recycling process.

“The plans for this facility were closely scrutinized by the regulatory authorities and local citizens,” says Lou Gherlone, owner of Spring Street Recycling. “We had to satisfy everyone that we had proven technology in place to run a very clean operation that wouldn't contribute dust to neighboring wetlands or the communities.”

Spring Street crushes local demolition waste into aggregate that can be processed and re-sold as clean fill material. Tokeep dust to a minimum, the facility employs internal dust control integrated into its crushing operation. But some dust still escapes, and that's where DB-60 comes in.

The airborne particles are knocked down by the DB-60's oscillating ducted fan, powered by a 25-horsepower motor. Its 200-foot throw, which can cover an area of 21,000 square feet, and an internal booster pump that delivers 150 psi of pressure also help to eliminate stray dust.

Less dust means that the West Haven-based recycling plant can stay open. That's important, Gherlone says, because “from every mile of concrete pavement of average thickness, nearly 6,000 tons of material can be reclaimed,” and “that means no landfill and no disposal fees.”
