Waste Industries USA, Inc., Selects Cleantechnics for Installation of High-Performance Oil Filtration Systems

HIGH POINT & RALEIGH, N.C.--(Business Wire)--
Cleantechnics International, Inc., today announces that Waste
Industries USA, Inc., has chosen its bypass oil filtration system to
begin to outfit its fleet of heavy trucks. Waste Industries has begun
to install the CTI filters on its fleet in Garner, NC, and will expand
the program over time throughout the fleet, eventually outfitting
several hundred pieces of equipment. As was shown in an in-the-field
pilot test, the outfitted equipment will experience dramatically
extended filter change intervals and increased engine durability,
which will in turn provide significant cost savings.

"We're excited about this transaction for several reasons," said
Cleantechnics CEO Bruce Thomas. "Waste Industries is a forward-looking
company, and we're gratified that they've chosen our product to help
reach their goals of reduced waste and operating costs. The company is
also a leader in the field, and we hope that its decision will inspire
other operators of heavy trucks, heavy equipment and over-the-road
trucks to seek us out for more information on how our bypass
filtration systems can help them reach their goals."

"The CTI filtration system was ideal for our situation," said
David Peck, Fleet Manager for Waste Industries. "We were seeking a way
to reduce our carbon footprint in keeping with our corporate
philosophy, but we also wanted to reduce our fleet's operating costs.
With Cleantechnics, we got both of those things in an easy-to-install,
easy-to-operate package."
