Environmentally sound recycling of nickel cadmium batteries

Publisher Summary Rechargeable nickel cadmium (Ni–Cd) batteries possess attributes that make them ideal for powering portable appliances such as cellular and cordless telephones, portable household appliances, and power tools. Concern exists that after the useful lives of these batteries has ended, they may become a source of cadmium and nickel that reaches the environment. Recycling Ni–Cd batteries addresses this concern and also conserves valuable natural resources. Used Ni–Cd batteries do not trade freely as commodities because the cost of collecting them for recycling exceeds the value of their reclaimed constituents. Faced with this challenge, companies that manufacture and use these batteries have developed and implemented collection programs in several national jurisdictions, and are now working to coordinate these activities intemationally. The chapter examines the key elements necessary in establishing a successful rechargeable Ni–Cd battery recycling program.
