Every day at work (furnaces, heat pumps and AC condensing units, some RTUs). It's a big pile. Refrig gets evacuated and the scrap guy comes by once a week (or twice a week if needed. Nothing interesting in the pile usually. Most of it is less than 15 years old.
Outside of work, not much. Probably for the better, I don't think my wife would like me to bring things home. If I brought dishwashers, fridges washers, etc. home, I'd probably be sleeping out in my yard that same night.
I love it when I come across old cars, trucks, home appliances and strange industrial contraptions on a hike. The strangest thing I've come across was an old IBM PS/2 computer tower in the middle of a dark forest, miles from any road. Wondered why or how it got there. Couldn't have been tossed out of a plane because the machine was intact (just mossy and a little rusty). I actually took the time to open it, and yes, the hard drive was still in the machine, in addition to the motherboard, IDE cables, expansion cards and PSU.
I wondered what was on the HDD on that old PS/2 in the middle of the woods. If I were a millionaire, curiosity would have gotten the best of me and I would have paid dearly to send it to one of those data recovery specialists capable of recovering severely damaged drives, all on a whim. Maybe it would have been innocuous: a bunch of spreadsheets and business letters. Then again, maybe I wouldn't want to know what was on that HDD.
