HAZARDOUS WASTE
Photographic Waste Segregation 2,975 Hazardous Waste $14,875 $10,000 $4,875 Photography and Graphic Arts Division implemented a pollution prevention project funded by the P2 Council that segregates hazardous fixer from non-hazardous developer. This reduces the hazardous waste stream by approximately 350 gallons (2,975 lbs.) annually, avoiding hazardous waste disposal costs of approximately $14,875.
Mercury Reuse 25 Hazardous Waste $1,000 $0 $1,000 Medical Department staff filtered and recycled approximately 1.6 liters of mercury rather than disposing of the mercury as hazardous waste. This avoided disposal costs estimated at $1,000.
Chemicals (various) Reuse 6,000 Hazardous Waste $30,000 $0 $56,000 As part of the HFBR Facility Stabilization project, Reactor Division staff redistributed 1300 chemicals to researchers around the Laboratory. Reuse of these materials (estimated at 6,000 lbs.) avoided disposal costs of $30,000 and material costs estimated at $26,000.
Borated Polyethylene Sheets Reuse 1,188 Hazardous Waste $5,940 $0 $5,940 As part of the HFBR Facility Stabilization project, Reactor Division staff transferred 1,188 lbs. of borated polyethylene sheets, used as neutron shields, to the National Synchrotron Light Source for reuse, avoiding disposal costs of $5,940.
Hydrogen Gas cylinders Reuse 6,200 Hazardous Waste $31,000 $0 $31,000 As part of the HFBR Facility Stabilization project, Reactor Division staff returned 31 cylinders (estimated at 200 lbs/cylinder) of hydrogen gas to the vendor, avoiding disposal costs of $31,000.
Sulfuric Acid Reuse 20,040 Hazardous Waste $100,200 $0 $100,200 As part of the HFBR Facility Stabilization project, Reactor Division staff contacted the vendor of this material and arranged a return of 1200 gallons (20,040 lbs.) of sulfuric acid for no cost. This transaction avoided disposal costs of $100,200.
Boron trifluoride gas filled detectors Reuse 200 Hazardous Waste $1,000 $0 $1,000 Boron trifluoride gas filled detectors were returned to the manufacturer for reuse, avoiding disposal as hazardous waste. Approximately 200 lbs. of material was returned, estimated savings of $1,000.
Lead Acid Batteries Recycled 7,250 Hazardous Waste $36,250 $0 $36,250 Estimate 50 lbs./battery and avoided disposal costs as hazardous waste at $5.00/lb.
Ion Exchange wastewater Source Reduction 1250 Hazardous and Sanitary Wastewater $2,000 $500 $1,500 Prefilters were added to the deionization system to polish make up water entering the ion exchange system. This extended the useful life of the ion exchange resins, requiring less frequent regeneration. The regeneration process generates hazardous and sanitary wastewaters. The project is estimated to have eliminated 40 gallons of hazardous waste and 200 gallons of sanitary wastewater. Approximately $2,000 in disposal costs are avoided annually.
MIXED WASTE
Solvents Decay in Storage 85 Mixed Waste $10,000 $0 $10,000 Ten one-gallon bottles of High Pressure Liquid Chromatography solvent, characterized as mixed waste due to phosphorus-32 contamination was allowed to decay in through ten half-lives in accordance with the decay in storage requirements. This allowed the material to be recharacterized and disposed as hazardous waste instead of much more costly mixed waste. This is estimated to have saved $10,000.
RADIOACTIVE WASTE
Shield Block (concrete) Reuse 668,000 Radioactive Waste $1,295,920 $0 $1,295,920 In excess of 600,000 lbs. of shield block was reused on site by Plant Engineering and Collider Accelerator Department. Approximately 500,000 lbs. of activated shield block went to the Collider Accelerator Dept. for reuse as shielding for beamlines. Approximately 168,000 lbs. of block was reused by Plant Engineering for shielding at the scrap yard. This avoided disposal costs of approximately $1,295,920 (estimate 6,680 cubic feet at $194/cubic foot).
Radioactive Wastewater Reuse 3,400 Radioactive Wastewater $14,800 $0 $14,800 As part of the HFBR Facility Stabilization project, Reactor Division Staff collected and reused approximately 400 gallons (3,400 lbs.) of contaminated water during leak testing of piping systems avoiding disposal costs of $14,800 ($37.00/gal).
Tritium Exit Signs Source Reduction 800 Radioactive Waste $38,800 $12,000 $26,800 Removed 80 tritium exit signs from service and returned to the manufacturer . Replaced with energy efficient light emitting diode (LED) signs. Project reduced risk of tritium gas release and avoided disposal as radioactive waste. Savings from avoided disposal costs estimated at $38,800 (200 cuft at $194/cuft), less $12,000 implementation cost for total savings of $26,800.
Filters Decay in Storage 1,920 Radioactive Waste $9,312 $0 $9,312 Filters from the air handlers in the Linear Accelerator facility become contaminated with beryllium-7, a short-lived isotope eligible for decay. The filters were allowed to decay for over ten half-lives in accordance with the decay in storage requirements. They were surveyed and released as undetectable for disposal as industrial waste. This avoided disposal costs estimated at $9,312.
INDUSTRIAL WASTE
Antifreeze Recycled 935 Industrial Waste $4,675 $0 $5,675 Estimate avoided disposal cost of $4675 (935 lbs at $5.00/lbs) and material savings of $1000.
Blasocut Machining Coolant Recycled/Reused 60,000 Industrial Waste $304,800 $0 $304,800 Central Shops Division operates a recycling system that reclaims Blasocut machining coolant and supplies it labwide. 7,500 gallons of Blasocut lubricant were recycled in 2000. Recycling involves aeration, centrifuge, and filtration. Avoids cost of disposal as industrial waste ($5.00/lbs), plus an avoided cost of procurement of 6 drums of concentrate ($800/drum) for a total savings of $304,800. Cost of recycle is estimated to be the same as cost of procurement and preparation of proper dilution for use.
