Waste Management Announces Solution to Reduce Stormwater Pollution

Helps cities and municipalities improve stormwater quality

Waste Management, Inc. (NYSE: WM) today announced that it has entered into an agreement with AbTech Industries under which Waste Management will provide SmartSponge® to its customers including municipalities. Under the agreement, Waste Management has become the exclusive waste and environmental services company distributor of SmartSponge® in North America.

This new product is available now from Waste Management in Los Angeles and will be available soon in additional cities and municipalities throughout North America.

The new product uses an innovative and patented sponge-like material with polymers to filter, absorb and solidify petroleum hydrocarbons. It also removes other pollutants found in runoff from roads and other paved surfaces during wet weather, cleaning or through direct spills. The product’s registration as an antimicrobial that reduces coliform bacteria found in stormwater, has been approved by the EPA. Once used, the product can be safely and responsibly disposed of in a waste-to-energy facility as an alternative fuel in the production of electricity or in a landfill as municipal solid waste.

“Our customers will see enhanced compliance with water quality regulations through improved stormwater quality,” said Paul Pistono, vice president of WM’s Public Sector Solutions. “Stormwater pollution is the leading cause of water quality problems in the U.S., according to the U.S. Environmental Protection Agency. We can now offer our city and municipal customers a new technology that will help them keep their communities cleaner.”

WM soon will begin offering the new service to its municipal customers in Northern Florida, North and South Carolina and Eastern Canada.
