Emission estimation calculators, booklet 1: chapter 14

Waste Oil Combustion

This calculator was designed to assist with estimating the releases of National Pollutant Release Inventory substances from the burning of waste oil. The substances of concern in this activity are Metals (Part 1 Substances), Criteria Air Contaminants (Part 4 Substances),and Speciated Volatile Organic Compounds (Part 1 and 5 Substances).

Suggested estimation methodology: Emissions Factor

The equation for emissions estimation is:

E = A x EF


  • E = emissions
  • A = activity
  • EF = emissions factor


A = Waste Oil Burned [cubic meters]
B = Ash Content in Oil [%]
C = Sulphur Content in Oil [%]
D = Lead Content in Oil [%]
G = Chlorine Content in Oil [%]

Note: if the waste oil burned is known in liters it can be converted to cubic meters by dividing by 1000.

Note on Emissions Factors

The default emission factors are used in the table above, however if you have a site specific emission factor you would prefer to use you may enter it in the emission factor column. If you choose to insert your own emission factor ensure that the units have been converted accordingly. 

The emission factors used in this spreadsheet are based on uncontrolled emissions. If you are using an emission control device you will have to adjust the emissions calculated by this spreadsheet according to the following formula:

Controlled Emissions = Uncontrolled emission x ((100 - control efficiency)/100)
