GreenMan Subsidiary Signs Agreement With Waste Connections, Inc. to Test CNG/Diesel Dual Fuel Upgrade on Refuse Transfer Trucks

CARLISLE, IA--(Marketwire - February 7, 2011) - GreenMan Technologies, Inc. (OTCBB: GMTI) announced that its American Power Group Inc. ("APG") subsidiary has signed an EPA Test Vehicle Agreement with Waste Connections of Colorado, Inc. to convert one of its refuse transfer trucks to APG's dual fuel system and begin on-the-road test trials and emission compliance approval. APG recently became the first company in the U.S. to receive a Vehicular Memorandum of Exemption from the United States Environmental Protection Agency ("EPA") allowing public highway access for the testing and verification of APG's unique non-invasive dual fuel upgrade system on aftermarket diesel truck and tractor engines.

Waste Connections of Colorado, Inc. is a wholly-owned subsidiary of Waste Connections, Inc., an integrated solid waste services company that provides solid waste collection, transfer, disposal, and recycling services in mostly secondary markets in the Western and Southern U.S. The company serves more than two million residential, commercial and industrial customers across 27 states. Waste Connections also provides intermodal services for the movement of solid waste and cargo containers in the Pacific Northwest. The company was founded in September 1997 and is headquartered in Folsom, CA.

APG's dual fuel system converts diesel engines and diesel generators to function more efficiently and at a lower operating cost (net fuel cost savings of 25% - 35%) by seamlessly displacing 40%-70% of the normal diesel fuel consumption with CNG, LNG, or bio-methane. APG's system is non-invasive to the OEM engine and operates within all OEM performance controls with the flexibility to return to 100% diesel operation at any time. APG's dual fuel conversion and emissions reduction systems can help users achieve their sustainability goals through lower carbon monoxide, nitrogen oxide, and particulate matter emissions. In addition, the introduction of natural gas through APG's dual fuel system does not impact diesel engine power or pulling torque and will assist in extending the engine's oil life as natural gas is a cleaner burning fuel compared to diesel.

The test exemptions will allow APG to gather critical engine performance and emission data on a pre-dual fuel and post-dual fuel basis to support EPA approval requirements and commence commercialization of their non-invasive dual fuel upgrade system in the United States. The initial vehicle to be tested for Waste Connections of Colorado, Inc. will be a 2007 11.5Liter /405 HP Mack refuse truck operating in the Denver metropolitan area.

Lyle Jensen, GreenMan's President and Chief Executive Officer, stated, "We are pleased to initiate test trials with Waste Connections which is the fifth largest solid waste company in the United States according to Waste Age magazine's 2010 Waste Age 100. With this announcement, two of the top ten solid waste companies in the United States have elected to test our APG dual fuel system which supports our belief that the aftermarket refuse industry will be a large addressed market for commercializing our dual fuel technology. Waste Connections, which operates a fleet of over 3,000 vehicles nationwide, is dedicated to implementing meaningful sustainability initiatives which include using CNG and LNG as an alternative to diesel fuel, as well as harvesting methane gas from landfills to generate renewable energy to power homes, small industry, and eventually, their fleets. Our test trials will start with a conversion to compressed natural gas and we anticipate future tests could include landfill bio-methane and other bio-gas sources of fuel." 

Greg Thibodeaux, Vice President of Maintenance & Fleet Management for Waste Connections, stated, "Our EPA test trial with American Power Group is a continuation of our efforts to evaluate and integrate emerging technologies into our waste hauling and disposal operations. Benefits from these successful projects would include decreasing our nation's dependence on foreign oil, reducing greenhouse gas emissions, and stimulating economic growth by creating green jobs. We look forward working with APG to validate the benefits of their technology."
