"Stack testing conforming to U.S. Environmental Protection Agency standards were conducted by an independent U.S. testing company in May 2005, comparing the LDPE (#4) Korean pellets with granulated HDPE (#2) discarded barrels. Three main groups of pollutants were analyzed:
• gases (sulfur dioxide, oxides of nitrogen, carbon monoxide)
• particulate matter
• dioxins/furans
Test results proved that this is an extremely clean burning system in all three groups. The Pennsylvania Department of Environmental Protection (DEP) has reviewed the results, noting that combustion units with a heat input rating of 2.5 million Btu / hr. or less are exempt from the plan approval and operating permit requirements. This means the burner and associated boiler can be marketed in the Commonwealth of Pennsylvania now and without restraint.
However, sites will still have to comply with the DEP opacity regulation, Section 123.41. According to the DEP standard, opacity, or visible air contaminants, cannot be equal or greater than 20 percent for a period or periods aggregating more than 3 minutes in any 1 hour, or greater than 60 percent at any time. For this extremely clean burning system, the opacity regulation testing will most likely not be an issue, hopefully merely a formality."
