4. Disposable Cylinders Product Descriptions Portable, convenient fuel gas source contained in small steel cylinder. Portable, helium gas source for balloon inflation. Portable, refrigerant recovery and collection cylinder primarily used in the commercial HVAC industry. Cylinders are manufactured and shipped in accordance with U.S. Department of Transportation regulations. Cylinders are not intended for re-use.

5. Product History Disposable propane Developed in the early 1950’s for use with portable hand torches for heating, soldering, brazing. Used with camping appliances such as heaters, lanterns and stoves beginning early 1970’s. Two disposable cylinder manufacturers: –Worthington Cylinders: Chilton, WI facility since 2005. Prior to 2005, Western Industries operated the facility, dating back to the early 1960’s. –Coleman Company: facility in Wichita, KS

6. Today’s Reality Non-refillable Disposable Gas Cylinders Tens of millions of fuel gas cylinders are sold annually. Well over half are used outdoors in camping related activities. Up to 30,000 tons of potentially recyclable material is discarded each year. (At roughly 1 pound of steel per unit) Most jurisdictions governing solid waste allow general disposal on non-refillable cylinders. Handling and recovery activity must comply with federal and state regulations and procedures (DOT, DNR, OSHA, EPA and local fire officials). Controls are necessary to assure safety and environmental responsibility in the workplace, community and during transportation.

7. Today’s Disposal Methods Government organized “Clean Sweeps” Local Household Hazardous Waste drop off locations Private service companies specializing in safe recovery and recycling State Park drop points Household trash for curbside pickup Littering or other improper disposal

8. Future Disposal Methods Manufacturer take back? Curbside collection? Retail take back? Household Hazardous Waste? Private entrepreneurs and cylinder recertifier locations? Exchange facilities? Other

9. Exercise Define the pros and cons of each potential disposal path.

10. Manufacturers Take Back Pros Regulatory understanding Product knowledge Cons Few locations Increased cost Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities

11. Curbside Collection Pros Very convenient Current programs exist for non- hazardous waste Cons Potentially unsafe Product education Haz-Mat transportation Un-regulated industry Employee/communi ty safety Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities

12. Retail take back Pros Retailer controlled Convenient Cons Increased complexity Lack of regulatory knowledge Public safety No Haz-Mat transportation Increased cost Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities

13. Household Hazardous Waste Pros Current programs established Cons High cost to manage Limited budget Inconvenient locations Limited bulk transportation ability Dependent on private service industry Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities

14. Private Entrepreneurs & Cylinder Recertifier Locations Pros Established processes Understanding of safety requirements Educated employees Cons Few locations Lack funding Inconsistent recovery methods to reduce cost Lack haz-mat transportation fleet Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities

15. Pros Convenient drop locations Developed infrastructure requirements Currently recovering and recycling larger cylinders Educated staff Safety understanding Experience with flammable gasses Cons Operating cost Possible Options Manufacturers take back Curbside collection Retail take back Household hazardous waste Private entrepreneurs and cylinder recertifier locations Exchange facilities
