TSX, AIM SYMBOL: QAR April 24, 2008 QuestAir to Supply Methane Purifier for 'Biomethane for Vehicle Fuel' Project in California VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 24, 2008) - QuestAir Technologies Inc. (TSX:QAR)(AIM:QAR)
announced today that it will supply an M-3200 pressure swing adsorption ("PSA") system to the
'Biomethane for
Vehicle Fuel' project located at the Hilarides Dairy in Lindsay, California.
Phase 3 Renewables LLC ("Phase 3") will integrate QuestAir's PSA into a plant that upgrades a
portion of the
biogas generated from the anaerobic digestion of manure at the 9,000-cow dairy in California.Purified
biomethane from the Phase 3 plant will fuel three heavy-duty milk trucks that have been
outfitted with engines
to run on biomethane fuel. The project, which is partly funded by the US Environmental
Protection Agency (EPA),
is expected to be operational by the fall of 2008.
Jonathan Wilkinson, President and CEO of QuestAir Technologies, said, "We are very pleased to
be part of this
project, the first commercial scale plant in North America to produce renewable biomethane
vehicle fuel from
agricultural waste." "California has the largest dairy herd in the US, producing nearly 30,000 tons of manure
annually. This project
demonstrates that this waste can be economically converted to renewable transportation fuel,
reducing air and
water pollution from manure, while also reducing emissions by replacing diesel trucks that
service the
industry." Norma McDonald, Owner and Operating Manager of Phase 3, said, "This project continues our
efforts to expand the
markets for farm-based biogas production. At today's prices, the plant will produce more than
$1 million worth
of fuel. We've integrated QuestAir's low-maintenance unit into a system that allows the farm
to obtain
substantial cost savings versus diesel fuel, while reducing operations and maintenance costs
per vehicle." About QuestAir M-3200 QuestAir's M-3200 purifies methane-containing gas streams such as anaerobic digester gas and
landfill gas to
high purity methane, suitable for supplementing existing natural gas supplies. The M-3200's
optimized Pressure
Swing Adsorption ("PSA") process and proprietary rotary valve technology deliver higher
efficiency than
conventional PSA systems in a more compact, cost effective package. QuestAir's M-3200 system
can upgrade up to
250,000 cubic feet of biogas per day.
