Around our area, it’s unusual to see a take-out place without empty big cooking oil cans outside. Hopefully they’re recycled as part of a commercial doorstep recycling programme but most of time it seems like they’re going to landfill - here they were next to a skip filled with other random rubbish. Very frustrating. If we took some of them, what could we do with them? I know after intensive cleaning, crude oil barrels can be made into woodburners/rocket stoves

and barbecues - could these essentially big tin cans be used for a similar thing on a smaller scale or is the metal not heavy duty enough? With the top taken off (and the edge made safe), I imagine they could be turned into planters for the garden - albeit ones that might rust over time. Any other suggestions?
