Tennant Company's ec-H2O Technology Selected as Sustainable Industries 2009 Top 10 Green Building Products Award Winner


MINNEAPOLIS - July 16, 2009 - Tennant Company (NYSE: TNC), a world leader in designing, manufacturing and marketing solutions that help create a cleaner, safer world, today announces that its ec-H2O(TM) technology has been selected by award-winning business magazine Sustainable Industries as one of its 2009 Top 10 Green Building Products winners. Sustainable Industries' Top 10 Green Building Products guide is an annual publication profiling industry-leading green building products selected by a panel of expert judges and the Sustainable Industries editorial team.

"In the four years Sustainable Industries has produced this popular, independent guide, green building has advanced to the mainstream," says Brian Back, founding editor and publisher of Sustainable Industries. "The Top 10 Green Building Products guide provides a unique snapshot of the most innovative building materials on the market today, which are particularly important given the increased strains on environmental resources."

Tennant Company's ec-H2O technology was selected as a 2009 Top 10 Green Building Products winner based on its environmental performance, scalability/market impact, innovativeness, design aesthetic, value and compatibility with the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) rating system.

Developed by Tennant researchers and engineers and named by R&D Magazine as one of the most technologically significant developments in 2008, ec-H2O technology helps to meet the ever-growing need for sustainable cleaning. The ec-H2O technology delivers proven cleaning results without the negative environmental and health concerns associated with producing, packaging, transporting, using and disposing of traditional cleaning chemicals. The technology starts with water and ends with water, so it can be handled and disposed of easily and safely. It uses 70 percent less water than traditional cleaning methods, which increases scrub time up to three times per tank. It also leaves behind no slippery detergent residue on the floor, and releases no used detergent discharge into water systems. Eliminating the need for chemical additives enhances worker safety and reduces costs for purchasing and disposal of chemicals.

"Tennant Company is committed to providing our customers with products and technologies that are good for them, good for their employees, and good for the environment. We are honored that our ec-H2O technology, which exemplifies Tennant's sustainable product innovation, has been recognized as a Top 10 Green Building Product by Sustainable Industries," said (name), (title) Tennant Company.
