My Dad used to get into the cinema for old jam jars.
(which he had to pinch from his mum's hoard - jam and marmalade were all home-made)
I think in older times (when LSD had a sterling meaning

, Paul), not just during rationing but long before, recycling was the norm rather than something "new", Paul.
Clothes, home-made in the first place, got mended, darned, patched, repaired and handed down; glass jugs and bits of pottery got stapled together; sheets were given the "sides-to-middling" treatment to make them last longer; table scraps were fed the pigs and chickens; folk chased along the road with a bag and shovel after horses; milk was delivered daily in glass bottles and the empties collected for reuse......
I had to take lemonade bottles back to the sweetie shop.
