Today's global economy has caused a big disadvantage of industry in developed countries, while in developing countries of labor costs and environmental regulations. The best method is to maintaining market share and reasonable profit margins which to  reduce manufacturing costs and minimize environmental compliance expense.

Industrial process efficiency improvements usually require higher operating temperatures. Lower emission control expenses require a need to replace outdated pollution control systems with innovative filtration technologies. Temperature dependent industrial manufacturing requires increasing the process exhaust temperature beyond the limits of the current cellulosic or polymeric filtration equipment.

The standard solution in moving to a higher temperature exhaust is a thermal oxidizer system. This technology is similar to a catalytic converter on a car. A ceramic or metal honeycomb is coated with a precious metal catalyst that converts emissions to harmless gas products at a temperature above the catalyst reaction temperature. Most industrial process exhausts do not reach this catalyst reaction temperature. Therefore, additional heat must be added by burning large volumes of natural gas. It can help to increase the process exhaust stream to the catalyst reaction temperature as it passes through the ceramic honeycomb. These costs for natural gas can reach from $100,000 to $5 million anually. But it all depends on  the exhaust stream's size.
