E-waste (electronic waste) refers to discarded electronic devices including computers, phones, tablets, televisions, printers, and small appliances. E-waste is the fastest-growing waste stream globally as technology advances and devices are replaced more frequently. Electronics contain valuable materials that can be recovered (gold, silver, copper, rare earth elements) but also hazardous substances (lead, mercury, cadmium) requiring careful handling. Most provinces have e-waste recycling programs, often funded by environmental handling fees charged when new products are purchased. Municipal waste programs typically direct residents to designated drop-off locations or special collection events rather than accepting e-waste in regular garbage. Responsible e-waste recycling ensures hazardous materials don't contaminate landfills or harm workers while recovering valuable resources. Data security is another concern—devices should be wiped before recycling to protect personal information.
