Cellular phones contain hazardous components and should not be disposed with regular trash. Phones in good working order may be reconditioned and reused.
Businesses can recycle worn-out cell phones at no charge by contacting Minnesota Waste Wise at (800) 821-2230. Some manufacturers of cell phones also accept cell phone accessories for recycling. The Wireless Association lists a variety of manufacturers and possible recycling options. Many donation opportunities exist; search the Internet using the key words "cell phone recycling."
Some electronic equipment recyclers also recycle cellular phones (see Computers, Electronics and Office Equipment). Contact your county environmental office for further disposal options.
