           QuestAir demonstration plant at City of Vancouver Landfill
                       recovers methane from landfill gas



VANCOUVER, B.C. - QuestAir Technologies Inc. (AIM: QAR; TSX: QAR) and the City
of Vancouver announced today that a demonstration project at the Vancouver
Landfill Site has begun upgrading landfill gas to methane suitable for injection
into the natural gas distribution system or for use as a transportation fuel.

Jonathan Wilkinson, President and CEO of QuestAir, said that the demonstration
plant will help the company market its commercially available M-3100 landfill
gas ("LFG") upgrading system to municipal landfills around the world.

"Oil and natural gas prices are at record levels and are likely to stay high for
the foreseeable future. These prices improve the economics of upgrading LFG to a
high value fuel that can supplement existing supplies of natural gas."

"In addition, purified methane recovered from LFG can also be used to fuel the
waste disposal trucks servicing municipal landfills, reducing both operating
costs and the greenhouse gas emissions of waste collection fleets," Wilkinson
said.

Paul Henderson, the City of Vancouver's Manager of Transfer & Landfill
Operations, said the joint demonstration project is an opportunity for the City
of Vancouver to participate in innovative work that can help extend the use of
landfill gas as a fuel source and reduce greenhouse gas emissions.

"Vancouver is among the leading municipalities embracing sustainability
objectives. The Vancouver Landfill is a model facility demonstrating sustainable
disposal of the fraction of solid waste that is not recycled or otherwise
removed from the waste stream," Henderson said.

"QuestAir's plant demonstrates an alternative to existing uses of landfill gas -
and is likely to be seen by other municipalities and landfill operators
throughout North America and Europe as a new technology to add economic value to
their LFG projects," Henderson said .

The Vancouver Landfill Site, owned and operated by the City of Vancouver and
located in the Municipality of Delta, serves approximately 940,000 residents in
the Greater Vancouver region. A system to reduce emissions of greenhouse gases
and local air pollutants from the landfill site by collecting and burning LFG
was installed in 1991 and expanded in 2001. In 2003 the City began utilizing a
portion of the LFG generated at the site for commercial purposes. Maxim Power
Corporation currently uses LFG from the site to generate electricity for sale to
the local electrical utility B.C. Hydro and hot water to heat a nearby
greenhouse operation owned Hot House Growers Inc.

The QuestAir demonstration plant upgrades up to 317,000 cubic feet of LFG per
day, producing sufficient purified methane to heat approximately 470 suburban
homes.


Energy recovery from landfill gas

   * LFG is produced by the decomposition of organic waste at municipal
     landfills. LFG typically contains between 40 and 55 percent methane, with
     the balance primarily carbon dioxide, plus minor amounts of nitrogen and
     other non-methane organic compounds.
   * More than 1,000 landfills in Canada, the United States and Europe
     capture energy from LFG by burning it to generate electricity or to heat
     buildings. To date, only a handful of landfills in the US and the
     Netherlands pursue a higher-value use for LFG by upgrading it into
     high-purity methane. QuestAir's M-3100 pressure swing adsorption ("PSA")
     system offers landfills a cost-effective means of upgrading LFG into
     high-purity methane suitable for injection into natural gas distribution
     networks or for the production of transportation fuels, such as compressed
     natural gas or liquefied natural gas.
   * In the United States, there are approximately 2,200 landfills.
     Approximately 450 of these landfills have operating energy projects, most
     generating electricity and/or heat through the combustion of LFG. These
     projects reduce greenhouse gas emissions by approximately 61.3 million tons
     of carbon dioxide equivalents per year - roughly equal to removing the
     carbon dioxide emissions of 11.8 million passenger vehicles. The U.S.
     Government's Environmental Protection Agency estimates that there are an
     additional 600 landfills suitable for LFG projects that can recover energy
     and reduce greenhouse gas emissions.

* In Europe, including the United Kingdom, there are more than 700
landfills that recover energy from LFG, with Germany, Italy and the UK having
the largest number of installed LFG plants. As in the US, electricity generation
is currently the most common method of energy recovery from LFG in Europe.

* In Canada, 16 landfills currently recover energy from LFG, with nine
projects generating electricity and seven projects generating heat for
industrial or agricultural uses. These projects reduce greenhouse gas emissions
by approximately 3.7 million tons of carbon dioxide equivalents per year - equal
to removing the carbon dioxide emissions of about 723,000 passenger vehicles.


About the QuestAir M-3100

QuestAir's M-3100 PSA product upgrades methane-containing gas streams to
high-purity methane, suitable for supplementing existing natural gas supplies.
QuestAir's M-3100 system can upgrade up to 9.0 million cubic feet of LFG per
day, producing sufficient purified methane to heat approximately 13,400 homes.


QuestAir's proprietary PSA technology was originally developed to purify
hydrogen for industrial markets, such as oil refineries, and for fuel cell
markets. QuestAir's PSA process and proprietary rotary valve technology deliver
higher efficiency than conventional PSA systems in a more compact,
cost-effective package. QuestAir has sold more than 60 PSA systems since 1997 to
customers in North America, Asia and Europe.
