Report by Leading Engineering Firm Verifies Nexterra Biomass Gasification Systems Deliver Superior Air Emissions Performance

VANCOUVER, Oct. 26 /PRNewswire/ – Nexterra Systems Corp. (www.nexterra.ca), a leading supplier of biomass gasification heat and power systems,
today released the results of an air emissions report developed by
Levelton Consultants Ltd., a leading engineering and science consulting
firm specializing in air quality assessment and management.

The Levelton study compared air emissions test results from Nexterra’s
gasification plants with comparable emissions data from conventional
combustion plants located in the US and Canada. The report confirms
that Nexterra’s facilities produce “best in class” air emissions when
compared with conventional biomass combustion technologies. For certain
types of emissions, Nexterra plants were also found to produce
emissions that were equivalent to or lower than natural gas combustion.

Key findings are as follows:

• Carbon Monoxide (CO) emissions from Nexterra’s systems are less than 2%
  of the CO emissions from the biomass combustion systems surveyed and
  are equivalent to or lower than emissions associated with fossil fuel
  generation facilities surveyed.
  
  
  

• Volatile Organic Compounds (VOC) emissions from Nexterra’s systems are
  less than 3% of the VOC emissions from the biomass combustion systems
  surveyed and are equivalent to or lower than emissions associated with
  fossil fuel generation facilities surveyed.
  
  
  

• Particulate matter (PM) emissions from Nexterra’s systems are equivalent
  to or better than the best emissions performance demonstrated by
  biomass combustion systems. In addition, Nexterra’s systems exhibit
  characteristics that make them particularly amenable to good control of
  PM levels.
  
  
  

• Nitrogen Oxide (NOx) emissions from Nexterra’s systems are lower than
  the US Environmental Protection Agency’s (EPA) AP-42 air emissions
  regulatory factors for biomass systems and, when coupled with Selective
  Non-Catalytic Reduction (SNCR) technology, can reduce NOx to levels
  comparable to low NOx natural gas combustion systems.
  
  
  

• Nexterra systems can achieve PM and CO thresholds for the US EPA’s
  proposed Boiler MACT (Maximum Achievable Control Technologies) rules
  for both Area and Major Source categories. In contrast, many of the
  biomass combustion systems surveyed do not achieve the proposed Major
  Source PM limits, and none achieve the proposed Area Source CO limits
  for new facilities.

“Nexterra has achieved impressive air emissions results at its
commercial biomass gasification facilities,” said Alex Schutte, Vice
President Environment and Energy with Levelton. “The results clearly
show that Nexterra plants achieve significantly lower levels of CO and
VOC emissions compared to the combustion facilities surveyed. Nexterra
facilities also demonstrate particulate emissions performance that is
as good as the best performance demonstrated by direct combustion
systems and these systems are particularly well suited to enable good
control of PM. Finally, Nexterra’s systems, when coupled with SNCR
technology, can achieve NOx emissions that are comparable to natural
gas.”

“Our goal in Vancouver is to become the greenest city in the world, and
one way we can do that is by using cleaner energy in our day-to-day
lives,” said Gregor Robertson, Mayor of the City of Vancouver. “Making
the shift away from fossil fuels towards low-emission energy is crucial
for us to meet our climate change goals. The technical breakthrough
achieved by Nexterra means that biomass energy can play a critical role
in helping Vancouver and cities around the world achieve their
sustainability targets without compromising air quality.”

“Our customers demand cost effective biomass solutions that achieve the
highest standards of air emissions, reliability, fuel flexibility and
efficiency,” said Jonathan Rhone, CEO of Nexterra. “We are fully
committed to delivering products that meet and exceed our customers’
expectations through continued investment in innovation and product
development. This study provides further validation of our technical
performance, innovation processes and underscores our commitment to
achieving the lowest possible air emissions.”

Air emissions from Nexterra systems are routinely tested by qualified
third parties at customer sites and at Nexterra’s Product Development
Center.
