Water Treatment

Challenge:

One of the largest regional districts in Canada—supplying waste and water services to more than two million people—operates water treatment plants that produce waste sludge.
Over the years the sludge from these plants has been landfilled, which was not a sustainable long-term solution.

Solution:

Plant modifications and investments were made at a nearby Geocycle facility so it could receive and process the sludge.
The sludge supplied alumina corrective which is a necessary component in the manufacture of cement.

Benefits:

• Straight line cost savings of $400,000 per year with no CAPEX investments.
• Significant improvement in reaching zero-waste targets.
• Enhanced reputation within community and image as a green city.
