SACRAMENTO, Calif. -- June 24, 2013

On the heels of the successful launch of the Sacramento BioDigester in
December, 2012, CleanWorld officially broke ground today to expand the 10,000
tons per year facility by 300 percent to 40,000 tons per year making it the
largest commercial high-solids food waste digester in the United States. Upon
completion in December, 2013, the Sacramento BioDigester will convert 100 tons
per day of food waste into renewable energy in the forms of heat, electricity,
natural gas, and fertilizer enhancements.

The Sacramento BioDigester received tremendous attention last year when
CleanWorld announced that the Phase I project, which broke ground June 2012,
had already began accepting food waste in early December. Earlier this month,
the Sacramento BioDigester began providing renewable compressed natural gas
(CNG) to the adjacent CNG Fueling Station operated by Atlas Disposal –
providing clean renewable fuel for the company’s waste hauling fleet.

CleanWorld – known as the North American leader in Anaerobic Digestion --
broke ground in May, 2013 on a 20,000 ton per year BioDigester at the
University of California, Davis – an innovative project that blends landfill
gas and digester gas to produce electricity for UC Davis. In 2012, the company
also placed into service the American River Packaging BioDigester in Natomas,
California, which produces electricity for the box manufacturing company.

When complete, the Sacramento BioDigester will produce 700,000 diesel gallons
per year of renewable CNG and prevent the release 18,000 tons of CO[2] into
the atmosphere. The CleanWorld facility will produce 8 million gallons a year
of organic soils and fertilizer products for Sacramento area farms and
agriculture and generate 1 million kilowatts of electricity to be used to
power the facility and the adjacent Fueling Station.

“With the Sacramento BioDigester, CleanWorld has taken an historic step
forward in developing innovative and cost effective waste management and
energy solutions,” said Shawn Garvey, CleanWorld’s Vice President of
Communications and Public Affairs.

CleanWorld’s proprietary anaerobic digestion technology, developed at the
University of California, Davis, and fabricated and constructed in California,
utilizes natural microbes to break down organic waste, generating biogas and
other forms of renewable energy. CleanWorld’s BioDigesters are pre-fabricated,
value-engineered, and modular-by-design, and require no additional water as do
many AD facilities – meaning the system is less expensive, significantly
shortens construction time and has a much smaller footprint.

“California leads the way in implementing cost-effective and sustainable waste
management solutions that solve renewable energy and environmental problems,”
Garvey said. “CleanWorld is working hard to put our US-made technology to work
in every city and state in the United States.”
