Toyota reduces air emissions with bio-oxidation technology
Portland, OR – As shown in Toyota’s 2008 North America Environmental Report , Toyota’s aluminum wheel plant in Delta, British Columbia, recently added a third paint booth to meet growing demand. As a result, VOC emissions were expected to increase. To alleviate the VOC increase, the plant needed to implement new emission reduction technology.
Traditionally the plant used regenerative thermal oxidizers (RTO) to reduce VOC emissions in the air stream. The plant instead opted for a Bio-Reaction advanced bio-filter system which biologically breaks down VOCs. By not opting for thermal oxidation, Toyota significantly reduced the energy needed to treat the VOCs and is keeping tons of new CO2 from being generated every year.
Toyota is not alone in its adoption of bio filters. Chemical processing, wood products, food manufacturing and other industrial sectors are replacing thermal oxidizers with bio-oxidation systems, drastically reducing natural gas consumption. By not combusting this natural gas to burn up pollution emissions, companies utilizing bio oxidation technologies are able to save up to 90% in operating costs and reduce their carbon footprint by 85% or more.
