Beer brewing

Download the breweries calculator to help you estimate the releases of National Pollutant Release Inventory (NPRI) substances.

Beer production releases criteria air contaminants (CAC) and volatile organic compounds (VOCs).

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 have a site-specific emission factor that you would prefer to use, enter it in the emission factor column, but be sure to convert the units correctly. 

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

where:

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

Input data

The activity rate parameter (A) varies with the substance and emission factor (e.g. thousands of cubic meters of beer packaged, tonnes of grain processed, tonnes of grain dried or thousands of cases of bottles washed.) Refer to the processes and EF units in the tables below, and consult AP-42 Chapter 9.12.1 - Food and Agricultural Industries: Beverages: Malt Beverages for more detailFootnote 2 .
