Update - Iowa Scrap Tire Program to Reuse 500,000 Pounds of Recycled Rubber

DES MOINES, IA--(Marketwire - July 10, 2008) - GreenMan Technologies (OTCBB: GMTI): Green is the new color of Iowa playgrounds thanks to an environmentally inspired partnership between the Iowa Department of Natural Resources (DNR), the Iowa Association of School Boards (IASB), GreenMan Technologies, Inc. and its wholly owned subsidiary, Welch Products, Inc.

The IASB is implementing the Iowa Safe School Playground Initiative, a program designed to heighten awareness around the benefits of recycling Iowa scrap tires and provide recycled rubber safety tiles to selected school playgrounds.

The Iowa DNR provided matching grant awards in the form of rubber tiles for playground surfacing made from recycled Iowa tires, and Welch Products' subsidiary, National Safe Surface Initiative (NSSI), will supply the recycled rubber safety tiles. This recycling education initiative will generate consumption of more than .5 million pounds of recycled crumb rubber. NSSI will be responsible for the initial site visit, design, installation oversight, ADA playground access certification, and Consumer Products Safety Commission safety certification upon completion of each project. More than 20 playground grants were awarded to Iowa schools. To receive this grant assistance, selected schools must hold an educational program showcasing the long-term benefits of environmental responsibility and recycling scrap tires.

Brian Tormey, Chief of Iowa DNR's Land Quality Bureau, said that IASB selecting GreenMan to facilitate this initiative was a natural choice. "Our office has worked with GreenMan over the years in the clean-up of illegal tire piles." Mr. Tormey added, "We are enthusiastic about our combined role in this recycling initiative focused on creating viable end-product markets for these scrap tires while also demonstrating to our school children the true benefits of recycling."

Lyle Jensen, Chief Executive Officer of GreenMan, noted, "There are multiple benefits of this program. The scrap tire education initiative not only provides our kids with safer, cleaner playgrounds, but it also provides a creative model for implementing recycled products. Using recycled rubber tiles improves child playground safety and provides ADA playground accessibility." Mr. Jensen added, "It also enhances the playground environment, which may encourage increased playtime and exercise activities that contribute to the fight against childhood obesity."
