Note 17: Raw materials efficiency


Waste

Effective waste management helps to increase raw materials efficiency in our manufacturing operations, reduces our environmental footprint and reduces costs. Our focus is on reducing total waste and eliminating hazardous waste to landfill. The exception is asbestos waste – mainly from demolishing old equipment and buildings – where the preferred current safe disposal route is properly designed landfill facilities.

  • Total waste per ton of production generated and leaving our sites was down 5 percent to 11.0 kg/ton (2011: 11.6 kg/ton). The total waste volume came down to 203 kilotons (2011: 217 kilotons), a decrease of 6 percent
  • We have realized improvements from projects implemented in the OEE program, resulting in a decrease to 85 kilotons of non-reusable waste (2011: 96 kilotons). Non-reusable waste per ton of production generated and leaving our sites was down 10 percent, to 4.6 kg/ton (2011 5.1 kg/ton). An example is the conversion of a sodium sulphate stream to a product which is now being supplied by Pulp and Performance Chemicals (Magog and Valleyfield)
  • The program for waste prevention through alternative outlets for obsolete paint materials has been successful. Around 15,000 tons of obsolete materials have been sold as by-product, which is being used as raw material for paint. This material would otherwise have been discarded as waste. Sustainable outlets have also been found for other by-product streams (7,500 tons)
  • Hazardous waste per ton of production stayed flat at 3.8 kg/ton (2011: 3.8 kg/ton)
  • The non-renewable hazardous waste to landfill was down 9 percent to 2.7 kilotons (2011: 3.0 kilotons)

Total waste

Total waste in kilotons (bar chart)

Waste means any substance or object arising from our routine operations which we discard, or intend to discard. Non-reusable waste is not used for resources, recovery, recycling, reclamation, direct reuse or alternative uses.

Hazardous waste

Hazardous waste is waste that is classified and regulated as such according to the national, state or local legislation in place.
