Use them as bricks and build houses.

  Given the season, I'd been thinking of an ice house. But I suppose that one could fill them with concrete, and stack them. Maybe scatter some small rocks between layers, so they deform and ~interlock. And maybe even punch some rebar through them. But you'd need to cover the outside, to slow weathering. And stuff doesn't stick well to polyethylene. Gorilla glue does, so you could add a layer of foam, and then siding. I suspect that getting a construction permit would be iffy, though.

    I think you could use them for something like earthbag construction, filled with soil. Would have great insulative properties as long as you fill in the cracks with mud 'mortar'.

      That's a better idea. Concrete has substantial CO2 cost.
