- Emission factors from the diesel engine powering the tub grinder were taken from AP-42 (10/96), Section 3.4. PM emissions from bark grinding were shown as 0.16 lb/ton, as derived from stack testing on an identical unit operated in Arkansas. All combustion PM is assumed to be PM 2.5, and 10% of PM from wood grinding was assumed to be PM 2.5.

What are emission factors? Emission factors are greenhouse gas (GHG) emissions per unit of activity data. GHGs should always be reported in Carbon Dioxide Equivalent (CO 2 e), a common unit that normalizes all GHGs in terms of their the global warming potential (GWP) or global temperature change potential (GTP), depending on which set of …
