PVT Landfill operates a landfill site on the island of Oahu, Hawaii, where it processes from 200,000 to 300,000 tonnes of C&D waste annually, including concrete, asphalt, wood, glass, masonry and roofing. The company crushes as much of the C&D waste as possible for use on its own roadways and as rip-rap to prevent erosion. The island's climate is such that it only receives a very small amount of rainfall, making the generation of dust a serious concern, especially when the wind gets up. General manager Steve Joseph said: We initially used conventional water trucks to help control the dust, and we continue to use them on roads and high-traffic areas. But we wanted a dust management technique that would give us more coverage."

PVT has opted for a DB60 DustBoss unit from DustControl Technology, which it has mounted on a lowboy trailer, paired with a generator and small water truck to allow it to be used anywhere across the site. This setup can cover more than 1,858 m2 (20,000 ft2)

Joseph said of the equipment; "It has great coverage and really knocks down the dust, and the cooling aspect is a nice bonus. It's not uncommon for temperatures to reach 90 degrees Fahrenheit or more out there, and having that fine mist projected over such a large working area really helps the men stay comfortable.
