Municipal solid waste incineration in Newfoundland and Labrador - conical burners

Download the municipal waste incineration in conical burners calculator to help you estimate the releases of National Pollutant Release Inventory (NPRI) substances.

Incineration of municipal solid waste (not including wood waste) releases:

  • mercury and its compounds (Part 1 substances)
  • hexachlorobenzene and dioxins/furans (Part 3 substances)
  • criteria air contaminants (CACs) (Part 4 substances)

This waste disposal practice is believed to continue in Newfoundland and Labrador. The calculator focusses on releases to air and uses default emission factors. It can be adapted to use site-specific emission factors if they are available. If you want to use a site-specific emission factor, enter it in the emission factor column, but be sure to convert the units correctly. (See also: Guidance on reporting the releases of NPRI substances for conical burners in Newfoundland and Labrador.)

The spreadsheet calculators use emission factors based on uncontrolled emission sources. If you use an emission control device and the default emission factor is uncontrolled, use this formula to adjust the spreadsheet calculation:

Controlled emissions = uncontrolled emission x ((100 - control efficiency)/100)

Since NPRI reporting thresholds are for the facility as a whole, you may need to combine the air releases you calculate with releases from other sources at your facility.

The following sections explain how the spreadsheet calculator works.

Suggested estimation methodology: emission factor

The general equation for estimation using an emission factor is:

E = A x EF


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

Input data

A = quantity of waste incinerated [tonnes];

If A is not known, it can be estimated using the following equation:

A = B x 0.770 x (C/365)Footnote * 


A = Quantity of waste incinerated [tonnes per year]
B = Population served
C = Number of days of operation during the year
