Yesterday while cooking I set off the smoke detector, no I did not burn anything. They go off when I cook over a high heat. And yesterday once they started going off they would not stop. I ended up having to disconnect them all (they are hard wired with an interconnect) and I replaced them this morning. Aaaaaaaand let me tell you, I had a sleepless night last night knowing there were no detectors installed.

What do I do? Landfill. Nobody near me wants the ABS housing even if I pried out the electronics and the radioactivity of ionization alarms is too low to need hazardous waste disposal. There are so many more impactful things to care about than recycling two or three smoke detectors every ten years.
