Does anyone know what to do with empty propane canisters? (the kind that you use for propane space heaters etc).

Take it to U-Haul or AmeriGas, they often have a refill station.

Or try Home Depot, Lowe's, Wally World, CVS/Walgreens, etc etc, many of them run tank exchanges. For $20 or $30, you give them the empty one, and they give you a mostly-full one.

If you mean the little green 1lb ones, you can throw them away (take them to hazardous waste disposal if they aren't empty), or you can buy an adaptor for ~$20 and refill them from your big cans. Note once refilled, Fed law says you aren't supposed to transport them on the highway, but that's not a very enforceable law, at all.

I drill a 3/8” hole in each side and put them in metal recycle.

I have a drill press so it only takes a few seconds. One hole works but the second hole makes it more visible.

Bury them in the neighborhood AH’s fire pit?

Pacific Steel will buy them as scrap, provided they’ve been holed; other scrap dealers in other areas probably do also.
