Some cheapo skip bag companies will let you use them, but it's likely they're a little less than kosher.

I keep one in with the spare wheel in my car, as it saves the boot when I'm taking stuff to the tip.

If they don’t take up much space - keep them. Handy for storing stuff or covering things outdoors. But then, I do hoard.

In effect they are single use bags. Cubic yard / meter, they are only safe work loaded for that first use. Then scrap.

Depends where you are, down my way they are like gold dust, and people actually pay for them, for things like logs etc.

I'm sure if you put them on freeads\gumtree\facebook someone would take them off your hands.
