Oil Sands Waste Management

At one time or another, we all have challenges with our waste line. 

Our customer needed a waste management contractor able to embed itself into the site-wide service operation and provide waste management solutions in seamless alignment with the company’s pursuit of operational excellence. 

Our Customer's Challenge

Our customer looked to Tervita to solve a three-pronged waste management challenge:

  • Solid waste (landfill and hazardous waste) management: Segregation, sorting and landfill diversion tactics were required to deal with waste directly at the source. Leachate collection was a particular issue. Our customer had been using a vacuum back-up style truck to collect leachate, and at times the liquid level was proving unmanageable.
  • Ecopit (lined pit that consolidates fluid and sludge waste) : Our customer’s practice of transporting fluid and sludge waste by vacuum truck was costly and inefficient.
  • Lime sludge: Our customer had been managing this waste stream with lugger bins – a labour-intensive application whose manual processes presented personal safety risks.

Tervita's Solution

Segregation & Waste Classification

Tervita employed hazardous waste bins, sorting containers and personnel to sort and organize solid waste directly at the source.

Transportation & Disposal

To remove solid waste leachate, Tervita used tanker trucks, whose higher capacity reduced leachate transportation costs by 60%. We also used tanker trucks to haul fluid waste from the ecopit. Their significant capacity advantage over vacuum trucks (30 vs 8 m3) reduced fluid handling costs by approximately 50% while reducing the carbon footprint of transporting waste to our salt cavern disposal facility in Lindberg.

Process & Safety Improvements

To transport lime sludge, Tervita used hooklift roll-off bins and a roll off truck. In addition to improving on-site safety by eliminating manual activities from the process, this approach eliminated the need for chain hooks and hoists. And by replacing 11 m3 lugger bin with 23 m3 roll-off bins, we significantly reduced the costs associated with lime sludge transport.
