In the summer of 1973 I took a job (as an in-betweener) for a 55 gallon drum recycling company, what we call 44 gallon drums, now 200 litre.

We used to get half used drums of avtur, jet fuel, which worked really well in kerosene lamps and heaters.

The bad stuff was drums of rancid tallow which were rolled through a hot caustic bath, then flushed with steam and water.

It stank like vomit, eight hours a day.
