Large-scale processors of yard trimmings, wood, land clearing debris and other organic materials are more conscious these days of all the equipment on their sites that run on high-priced diesel fuel. The Ketcham Group has operated a 64-acre organics recycling facility in Kings Park, New York since 1997, producing mulch, compost, soil and aggregates such as sand. The facility has made several equipment upgrades, used strategically to increase efficiency. The City of Greensboro, NC has owned and operated a yard trimmings composting site at its White Street landfill for the past three years. The city took the site over from a private operator, and began evaluating how to improve processing efficiency. Greensboro purchased an ALLU Model AS 38H windrow turner in August 2007, a machine large enough to process the facility's 32,000 tons/year of yard trimmings, but also quiet, powered by a 450-horsepower turbo diesel engine.
