A clean-air technology system installation has been tested and confirmed to be in compliance with the U.S. Environmental Protection Agency’s air pollution control regulations for plywood and composite wood products, according to the system’s maker.

TurboSonic Technologies Inc., Waterloo, Ont., says the installation, which treated the combined exhaust gases from a particleboard press and dryer to reduce VOC (formaldehyde and methanol) emissions, is the third one at Arauco-USA's Moncure, N.C., wood-panel production facility. Other installations, which treated exhaust gases from a medium-density fiberboard dryer and press, previously were determined to meet applicable regulations, TurboSonic says.

The manufacturers’ CGT technology eliminates the need for the combustion of natural gas, avoiding the associated greenhouse gas emissions of CO2, nitrogen oxides (NOX) and methane, the company says.

"We see this as the next step forward in wider acceptance of CGT technology,” says Edward Spink, TurboSonic CEO. “Due to the similarity of this particleboard process and emissions to the oriented-strand board [OSB] process, we believe this will lead to the successful introduction of CGT into the large OSB market."
