Toronto, ON — Safety-Kleen Canada Inc., has been awarded a three-year contract by the Toronto Transit Commission (TTC) to recover and re-refine 600,000 litres of used lubricants generated annually by the TTC fleet. The used lubricants recovered from the TTC will be physically and chemically treated in a state-of-the-art re-refining process and then returned to the TTC for use in its fleet.


Since 1989 the TTC’s fleet has been using between 500,000 and 740,000 litres of Safety-Kleen’s re-refined lubricants annually. With the award of this tender, Safety-Kleen will be both providing re-refined lubricants to the TTC and recovering waste oil for re-refining. This three-year contract effectively closes the loop with regard to TTC’s lubricant needs with a comprehensive cradle-to-cradle environmental management system.



The recovered lubricants will be processed by Safety-Kleen in its re-refinery in Breslau, ON, which re-refines more than 150 million litres of used motor and industrial oils annually.


“Re-refining used lubricants is widely recognized as the most energy efficient and environmentally effective way to reduce greenhouse gases and waste associated with the production, use and end-of-life management of lubricants,” said Dale MacIntyre, vice-president of refining for Safety-Kleen.


Re-refining offers the following environmental benefits:


– Producing engine oil from used lubricants generates 2.85 kg (or 80%) less greenhouse gases per litre than producing it from crude oil;


– Over the three year contact Safety-Kleen will re-refine 1.8 million litres of used TTC lubricants and will provide an equal amount of re-refined lubricants for use in TTC vehicles. This will reduce greenhouse gas emissions by 3.9 million kg as compared to manufacturing the same lubricants from crude oil. The greenhouse gas savings will be equivalent to taking 239 passenger vehicles off of the road annually; and,


– Re-refining used oil, rather than burning it as waste derived fuel in industrial boilers and asphalt plants, prevents the discharge into the environment of such toxic substances as arsenic, benzene, cadmium, chromium, inorganic nickel, polycyclic aromatic hydrocarbons (PAHs) and lead.
