CARLISLE, IOWA - GreenMan Technologies, Inc. announced Jan. 18 that its American Power Group Inc. (APG) subsidiary has signed an EPA Test Vehicle Agreement with Casella Waste Systems Inc., to convert one of its refuse 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.

Casella Waste Systems, Inc. is an integrated regional solid waste services company that provides collection, transfer, disposal, recycling, and resource management services to residential, industrial, and commercial customers, throughout the eastern United States. The company owns or operates 31 solid waste collection operations, 30 transfer stations, and 34 recycling facilities supported by a fleet of more than 1,000 vehicles.

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 percent) by seamlessly displacing 40-70 percent 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 percent 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 EPA 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 Casella Waste Systems Inc. will be a 2003 DT530 8.6L/275hp International refuse truck.

Lyle Jensen, GreenMan's president and chief executive officer, commented, "We are pleased to initiate test trials with Casella Waste Systems, Inc., the 10th largest solid waste company in the United States according to Waste Age magazine's 2010 Waste Age 100. We believe the aftermarket refuse industry will be a large addressed market for effective diesel fuel and diesel emission reduction technologies and this testing is a vital step in APG's move towards commercializing our dual fuel technology."

John W. Casella, chairman and chief executive officer of Casella Waste Systems stated, "We recognize that our industry is evolving towards a model that rewards an approach to resource renewal and sustainability. This includes, for us, developing a 'greener' fleet as we work towards reducing our diesel emissions ten percent by 2013. To get there, we are using innovation to rethink every aspect of our business and we look forward to working with American Power Group to test and determine the utilization of their alternative fuel technology in the Casella fleet network."

About GreenMan Technologies
GreenMan Technologies, through its subsidiaries, provides technological processes and unique marketing programs for alternative energy, renewable fuels and innovative recycled products. The Company's alternative energy subsidiaries, American Power Group, Inc. (APG) and APG International, Inc. (APGI) provide a cost-effective patented dual fuel technology for diesel engines. APG's dual fuel alternative energy system is a unique external fuel delivery enhancement system that converts existing diesel engines into more efficient and environmentally friendly engines that have the flexibility to run on: 1) diesel fuel and compressed natural gas ("CNG"); 2) diesel fuel and bio-methane, or 3) 100% diesel fuel depending on the circumstances. The proprietary technology seamlessly displaces up to 65% of the normal diesel fuel consumption with CNG or bio-methane and the energized fuel balance between the two fuels is maintained with a patented control system ensuring the engines operate to Original Equipment Manufacturers' ("OEM") specified temperatures and pressures with no loss of horsepower. Installation requires no engine modification unlike the more expensive high-pressure alternative fuel systems in the market. Our Green Tech Products, Inc. subsidiary, develops and markets branded products and services that provide schools and other political subdivisions viable solutions for safety, compliance, and accessibility including recycled surfacing.
