Equipment or process modification in practice

The following fact sheet presents an analysis of pollution prevention (P2) information submitted by facilities to the National Pollutant Release Inventory (NPRI) for the 2014 reporting year.

The analysis focuses on information from facilities that reported practicing equipment or process modification in 2014. Equipment or process modification is one of the seven common P2 techniques. It involves introducing new technologies or approaches to existing operating systems, processes and practices to improve production efficiencies and reduce pollution generated, and materials, energy or water wasted.

Which sectors reported practicing this pollution prevention technique in 2014?

Three hundred and twenty-four (324) facilities from 25 different sectors reported practicing equipment or process modification in 2014. The following table identifies the 5 sectors with the most facilities that practiced the P2 technique.

Number of Facilities Practicing Equipment or Process Modification by Sector Footnote1
Sector Number of Facilities Practicing Equipment or Process Modification
Wood Product Manufacturing 36
Primary Metal Manufacturing 29
Food Manufacturing 25
Chemical Manufacturing 24
Plastics and Rubber Products Manufacturing 22

Quick facts

  • Number of facilities that reported practicing at least one of the seven common P2 techniques in 2014: 953Footnote2

  • Number of facilities reporting equipment or process modification in 2014: 324

  • The most used equipment or process modification subtechnique: Modified equipment, layout or piping

  • The provinces with the most facilities that reported practicing equipment or process modification (with their percentage share of all facilities that reported practicing equipment or process modification):
    • Quebec: 103 (32%)
    • Ontario: 87 (27%)
    • Alberta: 45 (14%)
    • British Columbia: 42 (13%)
    • Saskatchewan: 14 (4%)

What were the most practiced equipment or process modification subtechniques in 2014?

In the NPRI reporting form, the individual P2 techniques are broken up into subtechniques. Facilities can select which subtechnique they practiced in that reporting year. Note that individual

facilities can report practicing multiple P2 subtechniques.

The following graph shows the number of facilities that reported practicing equipment or process modification subtechniques in 2014.

This bar graph shows the number of facilities that reported practicing sub techniques associated with equipment or process modification in 2014.

The breakdown is as follows:

  • Modified equipment, layout or piping: 153
  • Improved application techniques: 35
  • Instituted better controls on operating bulk containers: 29
  • Changed from small volume containers to bulk containers: 21
  • Modified spray systems or equipment: 18
  • Improved rinse equipment operations: 14
  • Modified stripping / cleaning devices: 12
  • Improved rinse equipment design: 11
  • Changed to aqueous cleaners: 10
  • Modified or installed rinse systems: 8
  • Changed to mechanical stripping / cleaning devices: 5
  • Changed from spray to other system: 3
  • Use of a different process catalyst: 3
  • Other: 166

Where was this pollution prevention technique practiced in 2014?

The NPRI tracks the location of each reporting facility. The following map shows the location of facilities that reported practicing equipment or process modification in 2014.

Figure 2
Figure 2 - Description

This figure is a map of Canada that shows the location of facilities that reported practicing equipment or process modification in 2014. The map shows that facilities which reported practicing equipment or process modification are located all across Canada, with a large concentration in Southern Ontario and along the Saint Lawrence River in Quebec. There is also a large concentration of facilities centered around Vancouver and running north to south in central British Columbia. Facilities are spread more broadly across Alberta and Saskatchewan.

Examples of how Canadian facilities practiced equipment or process modification in 2014

Facilities reporting to the NPRI can provide comments on their P2 activities, describing their initatives in more detail. The following examples are drawn from facilities that reported practicing equipment or process modification in 2014:

  • A plastics and rubber manufacturer in Ontario replaced an old inefficient electric batch oven with a new efficient natural-gas-fired unit. They also made changes to their tempering furnance to recover more waste heat, which has allowed them to reduce their overall use of natural gas by 50%, this despite adding their new gas-fired batch oven.
  • A food manufacturer in New Brunswick installed a new low-nitrous-oxdide burner in their primary boiler.
  • A printer in Ontario replaced their printing press with a new model that utilizes a spray and dry cloth cleaning system. This has led to a reduction in their usage of cleaning solvents.
  • A chemical manufacturer in Ontario has installed more efficient lighting throughout their plant. This will reduce their plant's energy consumption.
