An Oregon-based roofing company, which manufactures rubberized asphalt shingles, needed to reduce the amount of formaldehyde emitted by its manufacturing process. The rubberized asphalt shingles are made by laying down chopped glass, adding a binder, and then oven curing the mat. Formaldehyde is a byproduct of the fiberglass mat manufacturing process. The off gas is captured and sent to an oxidizer. When choosing a solution, the company‘s two most important factors were energy efficienc

Red Trail Energy, an investor group from North Dakota, operates a corn-based ethanol facility that produces up to 64 million gallons of ethanol per year. It was looking to increase ethanol production, which would require increased dryer and dried distillers’ grain solubles (DDGS) output.

The company wanted to take its current system, a heat recovery steam generator (HRSG) offline and replace it with a boiler to form a cogeneration plant. With this approach, the steam generated by the new boiler requires a regenerative thermal oxidizer (RTO) to process the dryer`s e
