Waste and water use

We strive to reduce our waste to landfill and water use where possible.

Waste and water use

During the year WesCEF reduced its water use by using dry ice rather than water to clean equipment where feasible.

We are working to reduce our waste to landfill intensity rate and to divert as much as possible to recycling, both in our operations and for our customers.

Water management is a material issue for Coles, WesCEF, Resources and Bunnings. Senior management of those businesses is responsible for assessing and managing water-related risks and opportunities and their divisional boards have oversight of these strategic risks and opportunities. 

We recognise that Australia is a highly water-stressed country and our focus is on using water more efficiently, reducing our water use intensity rate, ensuring dirty water is treated and replacing scheme water with reclaimed or recycled water where possible. 

This year, the Group recorded water use of approximately 13,422 megalitres. This represents a decrease in water use of 19 per cent due to the sale of Curragh coal mine as we have calculated the water use related to our Resources business up until it was divested in March. The decrease was also related to water efficiency projects at WesCEF with more details available here.

During the year CSBP changed its equipment cleaning process to include dry ice. Through the dry ice blasting method, carbon dioxide particles are propelled at high velocity using pressurised air to clean the surface of equipment.

Dry ice blasting has many economic, safety and environmental benefits.  It does not scratch, damage, or leave a profile on the surface being cleaned and can work at a much cooler temperature and lower pressure than traditional water methods.  In addition, dry ice blasting does not create any secondary waste in the cleaning process making it an attractive alternative to water blasting.
