Powdered lime disposal

Have been clearing the shed out and found a large container with what I believe to be powdered lime, which must be over 35 years old. Anyone any idea what is the best way to dispose of it?

I would phone the council surely they could help.

Yes I had thought of that, just wondered if anyone had got rid of some before. Will mail them.

We had a barrel of old damp proof fluid, which was full of horrific banned chemicals. I rang the council, who sent me to Gleadless tip, as they deal with controlled chemicals. Turned up and had to argue with the tip chap, because he didn't think they took it. I'd gone fore armed though, and he gave in eventually!

Just dig it into your soil and plant hydrangeas.

Sheffield soil is mostly acidic, the lime will neutralise the soil.

If you don’t want to do that, post on the Allotment section. Someone will take it off your hands.

Edit: I mean the lime, not the damp proof fluid

Is it a solid lump? I use this if it is OK where are you ?
