GreenMan Technologies, Inc. Subsidiary Wins Key Contract in California Market

DES MOINES, IA--(Marketwire - September 3, 2008) - GreenMan Technologies, Inc. (OTCBB: GMTI), a leading regional tire recycler of over 12 million scrap tires per year and emerging leader in patented cold-cure recycled rubber molded products, announced that its wholly owned recycled products subsidiary, Welch Products, has been awarded two separate contracts in the state of California, with a combined value of more than $500,000.

One contract is for the design, supply and installation of six playgrounds in the Orland Unified School District. The second contract is a playground surfacing contract with the LaTrobe School District. That project was partially funded by the California Integrated Waste Management Board ("CIWMB") waste tire unit and requires the use of value added products derived from California tires. To fulfill the CIWMB requirements, Welch's DuroMat "Extended Life" playground safety tiles were manufactured using California recycled tires. Welch's subsidiary, The National Safe Surfacing Initiative ("NSSI"), was awarded the contracts through its branded "National Playground Compliance Group" ("NPCG"), a partnership with the California School Board Association (CSBA) and Small School Districts Association of California.

"The state of California is the recognized leader in the establishment of public policies related to playground compliance and green technology, previously thought of as separate issues," stated Tim Mahoney, President of NSSI. "Our ability to provide a solution that implements the best practices in safety compliance and uses recycled products positions us very well in this market."

Larry Moody, NPCG's Senior Advisor for California, stated, "In a year when California Schools had a more than $10 billion budget shortfall, schools had to be very selective in their funding of capital projects. We are very pleased that our integrated offerings are being recognized as a valuable solution and funding priority."

"California is a key state for us in our overall growth strategy," stated Lyle Jensen, GreenMan's Chief Executive Officer and President. "These are the type of projects we expect to win as we continue to develop our market presence and brand recognition. It is evident through these projects that we are building a valuable model for our customers and we look forward to our continued growth in California."
