Chestnut shells belong to food waste (called wet waste in Shanghai).

Food waste is characterized by a very high content of moisture and organic matter, which can easily decay and produce a bad smell. It includes discarded unused leaves, leftovers, leftovers, peels, eggshells, tea dregs, bones, etc. Its main sources are family kitchens, restaurants, hotels, canteens, markets and other industries related to food processing. So chestnut shells belong to food waste.
