When you have finished with your old cellphone or battery, do not dispose of either in the garbage. There are various recycling programs which exist in your community to help you dispose of them in a sustainable and responsible manner. Most providers as well as some local charities offer programs. Contact your provider to find out how to participate.
The CWTA also offers a program – www.recyclemycell.ca. The program offers several drop-off locations or pre-paid shipping labels to send in your phone.
