New MultiPhase BioSystem™ Proves
Cost-Saving Alternative to Thermal Oxidizer
or Biofilter for VOC Control

Tri-Mer Corporation announces a major
advance in VOC control technology.
It is a more practical alternative to a thermal
oxidizer, biofilter system, and aerobic
digestion with trickling filter mass transfer.

The air emissions regulations of the MACT standard,
(Table 1B Subpart DDDD of Part 63: Add-on Control
Systems Compliance Options) now apply universally to
board manufacturing. Fortunately, there is now a cost-
effective, reliable, and proven technology for controlling
formaldehyde emissions, also methanol, terpenes, and
other VOC emission types generated by board plants,
as well as the manufacturing of fiberglass, adhesives,
resins and other materials.

This new MultiPhase BioSystem for VOC control combines the best of in-bed bioscrubber and
aerobic digestion technology with the high removal efficiency of enhanced scrubbing using a
variety of approaches, depending on the project.  It treats high inlet concentrations of VOC in a
tower configuration with a manageable, small footprint.  Unlike the large, in-bed biofilter approach
of the past, this proven new technology can be sited close to the emission source, minimizing
long duct runs. 

This unique VOC control technology is less expensive to install and less costly to operate than
older approaches. It provides high removal rates on high particulate concentrations and heavy
loadings of biological treatment products, without clogging the media beds.  Media is permanent –
no replacement of media or packing is necessary.  Initial costs are generally lower than competing
older biological approaches and the system is highly reliable, with lower maintenance and operating
costs plus superior performance. The MultiPhase is a fraction of the equipment costs of thermal
oxidizer systems without the enormous perpetual operating expense in natural gas.    

Tri-Mer’s new MultiPhase BioSystem for VOC control generates minimal waste
and does not create NOx by-products.  

The Tri-Mer system addresses a broad spectrum of VOC control challenges. Alcohols,
including methanol and other high vapor pressure VOCs, are simultaneously treated along
with more challenging VOC control issues, such as terpenes and pinenes.  Formaldehyde
emissions, perhaps the most problematical from a regulatory perspective, are readily removed. 
The system is highly flexible, with options for treatment of numerous volatile organic
compounds.  The underlying design philosophy focuses on MACT compliance. 

Time is critical in complying with air emissions regulations found in the VOC MACT standards.
The Tri-Mer MultiPhase BioSystem is a cost effective, reliable and proven solution. 

This new VOC control alternative is available exclusively through Tri-Mer Corporation, which
offers turnkey engineering , VOC emission control equipment manufacturing, installation
and project management.  With its own manufacturing facility in Michigan, and resources
nationwide, project schedules can be expedited and regulatory deadlines met.

Tri-Mer Corporation, a leader in particulate and VOC control and technology since 1967.

Tri-Mer’s MultiPhase BioSystem for VOC control meets the regulatory standards
applicable to manufacturers of engineered lumber, LVL, PSL, LSL and OSL.

These Industry-Leading Companies Chose
Tri-Mer for VOC Control . . .

Roseburg Forest Products manufactures and markets building materials and specialty
products that include lumber, plywood, engineered wood products, decorative melamine, MDF,
particleboard and specialty panels. Roseburg chose a Tri-Mer MultiPhase Biosystem for
VOC control at its 100 million ft. capacity MDF facility in Holly Hill, SC.

Collins Lumber Corporation, a supplier of lumber, building materials, custom millwork,
wooden trusses and wall panels, chose a Tri-Mer MultiPhase Biosystem for VOC control at
its Klamath Falls, Oregon facility. Collins was the first privately-owned forest products company
in the US independently certified by the Forest Stewardship Council (FSC). The FSC is the only
certification system endorsed by major environmental organizations, including the World Wildlife
Fund, Greenpeace, Rainforest Alliance, National Wildlife Federation, and the Wilderness Society.

Stimson Lumber Company is one of the oldest continuously operating forest products
companies in the United States. Its Resource Group manages 500,000 acres of company-owned
timberland, consistent with the Sustainable Forestry Standards of the AFPA.. For its hardboard
manufacturing facility in Forest Grove, Oregon, Stimson chose a Tri-Mer MultiPhase BioSystem
for VOC control.

On April 26, 2007, the Air Resources Board adopted an airborne toxics control measure
(ATCM) to reduce formaldehyde emissions from composite wood products, including hardwood
plywood, particleboard, MDF, and products created with engineered lumber products.

Formaldehyde is generated worldwide on a massive scale.  The ARB evaluated formaldehyde
emissions exposure within California and concluded that a major source of exposure is inhalation
of formaldehyde from composite wood products. The International Agency for Research on
Cancer has classified formaldehyde "carcinogenic to humans" due to an increased risk of
nasopharyngeal cancer. Formaldehyde emissions were also classified as a toxic air
contaminant in California, with no safe level of exposure.

The U.S. Court of Appeals for the District of Columbia has invalidated the
“low risk” subcategory provisions of U.S. EPA MACT emissions rules for
plywood and other engineered wood product facilities. The ruling means
that mills previously exempted from VOC control limits will now have
to install VOC control technology such as a thermal oxidizer,
biofilter or MultiPhase BioSystem.

The ruling also struck down a one-year compliance extension,
reverting back to October 2007 as the compliance deadline.
