Smoke and carbon monoxide detectors may be disposed of with regular garbage. Do not take the detector apart, but do remove batteries and dispose of them properly.
Batteries
Alkaline batteries may be deposited in the trash. Lithium batteries must be saved for a hazardous waste collection or can be brought to the Skokie
Health Department for Household Battery Recycling.
Smoke & Carbon Monoxide Alarms
Smoke and carbon monoxide alarms are not accepted at electronics recycling events. Some alarm manufacturers will take their own products back for recycling. Contact the manufacturer before mailing back an alarm/detector; some manufacturers charge a fee or have special requirements, if the device is no longer under warranty.
