Barb ... there was a recycling center in town that I used to pick up used nursery pots, cheap. One & two gallon where the easiest to find (I got 1,000 one gallon pots). Five gallon a bit harder to find and 10's and 15's where rare. I did buy from Eddies Nursery Wholesale but without a PST number now that's not possible.
It's not only "insurance regulations" but this stuff is worth money when sold to recycling plants.

Cheers, Barrie.

Ditto for Edmonton. The recycle depot usually has a number of 1 gal to 5 gal pots. But if the stuff goes into the waste bins you are not supposed to scavenge, Unless you are St. Vincent de Paul and similar societies that provide household goods to people who have lost everything.

Reuse should be the TOP priority in the recycling scheme.
These pots use considerable energy to be made into something else.

It'd be worthwhile to know a landscaping company, as they'd have larger sizes of pots.

Many years ago we were travelling through Atlanta Georgia.
There was a huge Architectural Salvage yard and warehouse.
We wandered through the yard: stone, brick, "gargoyles", fountains, iron gates, bathtubs, huge marble and stone driveway "lions".
Their warehouse was chock full of magnificent old--and huge--chandeliers, 50-foot long carved mahogany hutches and buffets, everything from old mansions.
Even a restored antique car section. Magical!

Here, in Western Canada, where the oldest building on the block seems to be a Midas Muffler Shop,
we're always tearing things down, rather than reusing existing buildings. 🙁

It does seem like a pity that we have a tendency to destroy everything.

Edmonton is one of the rare exceptions. Not because they are recycle friendly, but because they almost ran out of dump space. Edmonton's arrogant attitude toward the surrounding communities resulted in the communities retaliating and refusing to allow the city to put a dump in their counties. Now almost everything is recycled, drywall, concrete, grass clippings and vegetable waste, metals, most plastics. paint etc. There are at least 2 companies that recycle building materials and Restore that recycles small quantities of new building materials, used appliances and fixtures.

Dump capacity is a big deal in BC, too.

Like Edmonton counties, now there's a public outcry that "Burns Bog" in the Lower Mainland will be accepting waste that previously was shipped in B-trains to Cache Creek in the Interior.

Heard of a tiny community dump near Barriere BC where they still burn garbage out in the open...and yup, plastic plant pots were in the pile! If people only realized the toxins contained in that smoke 😥
