GreenMan Subsidiary Completes Conversion for Bhushan Steel Ltd.

LYNNFIELD, MA--(Marketwire - Oct 28, 2011) - GreenMan Technologies, Inc. (OTCQB: GMTI) (PINKSHEETS: GMTI) announced that its American Power Group Inc. (APG) subsidiary has completed the follow-on order for Bhushan Steel Ltd. ("Bhushan Steel"), New Delhi, India, to convert two MAN B&W generators (one 12MW and one 9MW) at their Khopoli industrial site to APG's dual fuel technology. Bhushan Steel Ltd. is India's third largest secondary steel provider with estimated capacity of 2 million tons per annum.

Lyle Jensen, GreenMan's President and Chief Executive Officer, stated, "In the case of Bhushan Steel, we installed our dual fuel technology on two additional generators which are used to supply primary energy for the operation of Bhushan's steel rolling mills and are the size of two greyhound buses stacked on each other. Based on the historical performance of the generators previously upgraded to dual fuel, we anticipate a payback of less than six months on Bhushan's most recent investment with us." Mr. Jensen added, "Our ongoing efforts and investments to enhance the functionality and cost competitiveness of our dual fuel technology are why we can offer cost effective solutions in such diverse markets. India is quickly becoming a large market for both generator and vehicular natural gas dual fuel opportunities. We recently received approval from the Automotive Research Association of India ('ARAI') to upgrade two heavy-duty test vehicles. ARAI is a cooperative industrial research association of the automotive industry and the Ministry of Industries in India. The approval will allow us to start gathering in-country vehicular data as we prepare to commercialize the significant number of heavy-duty trucks and transit buses in India."
