How do you compare stack emissions from waste incinerators?
Short answer
Match the pollutant, concentration unit, reference oxygen, wet or dry basis, averaging period, and operating conditions before comparing emissions values.
What a concentration can hide
A daily average and a short sampling-period average measure different things. A concentration also differs from an annual mass release. Compare the same averaging period and confirm reference conditions, or use separate columns.
Compare with the actual permit
The EU waste incineration BAT conclusions illustrate reference conditions and averaging definitions. A specific compliance assessment needs the applicable permit limit, measurement record, and jurisdictional rules for that installation.
