Carbon Monoxide (CO) is the byproduct of incomplete combustion. The byproduct of perfect
combustion is carbon dioxide and water. Modern trash-to-energy plants like this plant have such
thorough combustion that carbon monoxide is measured in the low parts per million rather
than percent (1% = 10,000 parts per million) whereas the amount of carbon dioxide is upwards
of 10%. This represents a combustion efficiency of over 99.99%! The Department
of Environmental Protection limits the plant to 69 parts per million
(69 ppm) of carbon monoxide in its emissions (corrected to 7% oxygen) during normal trash
combusting operations. This limit does not apply during periods when the facility is burning
natural gas, the first three hours of a start-up or shutdown or during a process malfunction.
