Starting around 9:00 pm every night, trucks of empty plastic barrels roll into the city to collect waste from restaurants. The foul smell of rotting food fills the air of the back alleys as the waste is poured out of garbage cans and into the barrels. A lot of the food scraps are used to feed pigs in the city’s farms. But the most popular collection points seem to be from hotpot restaurants, probably because the oil is still being illegally recycled. This recycled oil is called “gutter oil” and is particularly disgusting to read about.
I’ve walked past this truck hundreds of times as it’s always being loaded out the back of a hotpot restaurant just outside of my apartment. I’ve always wondered where the oil goes.
