Recycling Prosthetics Generates Environmental Ease
Recycling has clearly become an accepted and embraced practice in most North American communities. The practice is credited with extending the long-term availability of natural resources, reducing the impact of industrial production on the environment and conserving energy. When we think of recycling, it’s of opportunities at home: glass and plastic containers, newspaper and aluminum cans, etc. Recycling at the crematory most likely ranks far lower on the list, if at all. The use of orthopedic prosthetics in North America has boomed. More than 80 million North Americans suffer from some type of orthopedic condition. The number has clearly led to the sky-rocketing use of implants and their frequent appearance in U.S. crematories. Current implant technology uses metals such as stainless steel, titanium and cobalt chromium which are believed to have an approximate 15-year life. Metal components from the body and container are not destroyed by the heat and atmosphere of the cremation process. They remain in the cremation chamber among the cremated remains when the cremation process is completed. In addition to the metal remains from the caskets and containers (staples, screws, hinges and plates), orthopedic prosthesis or implants such as hip joints, knee joints, plates, rods and screws are left. The metallic orthopedic remnants are fabricated from high-grade metals such as stainless steel, titanium and cobalt chromium-all of which have recyclable value. Currently, most crematories separate metal remnants from cremated remains prior to processing them which reduces the size of the bone fragments. These metallic parts are placed into metal waste bins until there is sufficient quantity to dispose. Disposal of the parts is either performed at a cemetery where they’re buried, or more commonly, sent to the landfill with the other residential, commercial and industrial waste. Whether buried in a cemetery or at a landfill, the materials do not decompose with time, but rather take up finite land space permanently. Current disposal practices appear very inefficient, inadequate and environmentally unfriendly. So what are our options? Recycling orthopedic prosthesis implants left from the cremation process is now a common practice in many European countries where it began over six years ago. The process, if adopted in North America, would probably look something like this: Cremated remains swept from the cremation chamber- metallic items separated from the cremated remains –placed into recycling shipping bins-shipped to collection centers-metals sorted and re-melted- ingots sold to orthopedic and other manufactures-metal re-enters the material supply chain-new products for the marketplace. It’s plausible that recycled metal from the crematory can be remanufactured into new hip joints and end up at the crematory once again. Recycling these materials appears to be dignified and environmentally sound, reduces mining requirements for new metal, as well as reduces landfill space that would be occupied forever. What are some of the pros and cons of recycling orthopedic prosthetics?
