GreenMan Technologies, Inc. (Lynnfield, MA) sold its Green Tech Products subsidiary, marking its exit from the rubber recycling business. Under terms of the agreement, the buyer Irish Knight Holdings is purchasing Green Tech Products' assets while assuming its liabilities and is to provide $150,000 of additional consideration in the form of a promissory note and inventory credits. Green Tech was known as Welch Products Inc. when GreenMan acquired it in October 2007. Welch, which made playground safety tiles and other recycled rubber products, had been one of GreenMan's major crumb rubber customers. However, in 2008 GreenMan sold its scrap tire processing operations in Iowa and Minnesota to Liberty Tire Services of Ohio LLC, essentially exiting the rubber recycling business with the exception on the Green Tech subsidiary. GreenMan remains as an alternative energy and renewable fuel company, whose subsidiary American Power Group Inc., markets a patented dual fuel conversion technology for diesel engines and diesel generators.
