Innovative Biological Air Filtration Technology Demonstrates Energy-Efficient VOC Emissions Control at Lumber Mill
December 18, 2006
In order to comply with environmental regulations and air quality standards, it is critical for the wood products industry to control its emissions of hazardous air pollutants (HAPs) and volatile organic compounds (VOCs).
Biological systems that employ microorganisms to oxidize organic and inorganic pollutants into nontoxic byproducts are emerging as a promising alternative control technology conventional emissions control technologies, which require significant amounts of energy and generate secondary pollutants such as nitrogen oxides and excess carbon dioxide. In a project sponsored by the Industrial Technologies Program, researchers from Texas A&M University-Kingsville and Bio•Reaction Industries LLC have recently completed field-scale tests of a biological oxidation and air filtration system at Stimson Lumber Company in Forest Grove, Oregon. The testing has shown that a multi-stage bio-oxidation system is a viable control technology that uses less energy and costs less to operate than conventional systems.
The successful demonstration of the multi-stage bio-oxidation system lent data that supported a determination by USEPA Region IV that the BRI bio-oxidation system was acceptable as a best available control technology for press emissions, paving the way toward the greater acceptance and adoption of bio-oxidation systems throughout the Forest Products industry.
