Internal Program (1994 – Present)

• Refrigerant Recovery– 1994 – 1997

• +400 lbs. CFC Fleet Services• Processed using reclaimed equipment

– 1996 – 1997• +200 lbs. HCFC Building Maintenance

– 1999 – Present• +200 lbs 134a – Fleet Services

– 2008 - 2009• 7000+/8000 units• 0 Disposal Costs

Internal Program (2009)

• HHW Oil and Antifreeze Collection– 75,462 gallons used oil

• 9% collected volume

– 6,231 gallons of spent antifreeze• 19% collected volume

Internal Program (2009)

• Oil– Re-refined - Firebird 15-40 CJ4 = $6.65 gal– New (Virgin) - 15-40 CJ4 = $6.40 gal

• Antifreeze – Remanufactured - Extended Life 50/50 = $3.95 gal – #2 HDPE jug - Reusable = $1.97 ea– New (virgin) - Fleet Guard 50/50 = $11.65 gal

Internal

The used oil collected at the Cities, Colbert and Valley Transfer Stations and at the Waste to Energy Facility (65,792 gals in 2008) were processed at the Portland, OR refinery.

• Process yields from used oil.– 70% Lube oils (Motor, Hyd., and ATF) – 5% Water– 7-10% light Fuels. (Gas & Diesel)– 10-15% Asphalt

• Transportation costs from Spokane to Portland is approximately $180.00 • Cost is $0.25 per gallon more than virgin lube oils• Production of base oil from used oil requires only about 65% of the energy

required to produce base oil from crude oil

Internal Program (2009)

• Fleet Services (annually) – 6800 gallons of motor oil– 1200 gallons of antifreeze

• Purchasing remanufactured antifreeze• bulk quantities • re-packaging – refillable code 2• “closed loop”• Previously the code 2 containers were not recycled due to

antifreeze contamination

– Culture shift

Internal Program (2009)

• Diversion (reuse) vs. Reduction - norms

• Culture shift
