I have a quantity of used IBCs for sale near Forfar, Angus. £10 each.
They have previously contained various, unknown chemicals, mostly fertiliser concentrates, they will be washed out, but I would suggest not used for animal feed or water, but loads of other uses around the place.
We use the cages for storing/stacking logs as they allow plenty of air and can be easily moved from wood to yard, to beside house when ready.
Would be fab for raised beds, planted trees, seen pics on Internet of them used as hen houses, aquaponics tanks, mini green houses/cloches, many, many uses.
May be able to arrange local, Angus delivery.
Discount for large quantity.
Please send me a pm.
