There currently is not a specific smoke alarm recycling program. Also many smoke alarms contain radioactive material. Most of the major recycling centres offer hazardous waste days where toxic or hazardous items can be handed in for disposal.
Non lithium batteries on the other hand can be recycled. The best place to recycle batteries is also at major recycling centres.
Check Systems regularly disposes of batteries and smoke alarms in this way in order to minimise the footprint of our smoke alarm replacement service.
