2. H2E Teleconference2 Solvent Reclamation and Management\ At Baystate Medical Center Hazardous Waste Minimization - Solvent Recovery Systems and Product Substitution June 11, 2004 Solvent Reclamation Baystate Medical Center currently operates 5 solvent management units: Two distillation units (stills); two filters; and, a vial crusher to separate waste methanol and obliterate patient Information. Estimated savings from these operations is $19,000/yr.

3. H2E Teleconference3 A Brief History BMC began solvent reclamation in 1980. The original still was installed to reclaim a xylene from wax generated during tissue processing. A second still was installed in 1990 to recover ethanol from tissue staining.

4. H2E Teleconference4 Xylene Still – Used to reclaim xylene from a solvent/wax solution. Originally installed in 1980. Product is better than the reagent purchased to replace waste.

5. H2E Teleconference5 COST AVOIDANCE – Xylene Wax Still Cost avoidance of new product purchase$4,560 480 gallons/yr @ $9.50/gallon Cost avoidance of waste disposal$ 744 480 gallons/yr @ $1.55/gallon ______ $5,304 Initial cost - $15,000. The waste wax is disposed of as a flammable solid.

8. H2E Teleconference8 Methanol Filter – Used to reclaim Wright’s Stain. This gravity fed unit hold 6 gallons of stain per fill. Chromatographic analysis of reclaimed product matches new material with one exception. Reclaimed material has a “fruity” odor. Performance of reclaimed material is good.

9. H2E Teleconference9 COST AVOIDANCE – Methanol Filter Cost avoidance of new product purchase$7,405 500 gallons/yr @ $14.81/gallon Cost avoidance of waste disposal$2,275 500 gallons/yr @ $4.55/gallon ______ $9,680 Initial cost - $1,400. New filter cost - $500. After 10 months, the quality of the is still acceptable. Specific gravity is checked as a measure of quality. The filter is disposed of as a flammable solid.

12. H2E Teleconference12 Vyleater Vial Crusher – Crushes methanol containing vials to remove liquid and disfigure patient information. Solvent Reclamation and Management\ At Baystate Medical Center Hazardous Waste Minimization - Solvent Recovery Systems and Product Substitution June 11, 2004

13. H2E Teleconference13 In 2003, 82,000 vials were processed. Approximately two gallons per week of liquid waste are generated. Solvent Reclamation and Management\ At Baystate Medical Center Hazardous Waste Minimization - Solvent Recovery Systems and Product Substitution June 11, 2004

14. H2E Teleconference14 COST AVOIDANCE – Vyleater Vial Crusher Barrel all vials and dispose of as hazardous waste Estimated @ 41 drums/year @ $250/drum$10,250 OR Ergonomic exposure of opening all vials and pouring off the liquid $ !!!!! Initial cost - $20,000. The liquid waste is disposed of as a flammable liquid. The crushed vials are disposed of as regular trash.
