Chestnut shells are wet garbage.

Generally speaking, chestnut shells are wet garbage, a type of melon peel and kernel garbage, and should be put in a garbage can marked with a non-recyclable word or icon when disposing of them. Other garbage of the same type, such as coconut shells and pine cone shells, can also be discarded in the same way.

In fact, chestnut shells belong to food waste. Although most nut shells are dry waste, chestnut shells are relatively softer and can be processed by wet waste terminals, so they belong to wet waste, i.e. food waste.

Characteristics of wet garbage:

Wet garbage does not mean garbage that is wet or contains a lot of water. Wet garbage refers to biomass waste generated by daily life that is easy to rot, including leftovers, melon peels and fruit kernels, kitchen garbage, flowers and ferns and greens, expired food, and animal offal. Although chestnut shells are dry solids, they are not categorized as dry waste because dry and wet waste are not differentiated on the basis of water content.

Dry garbage refers only to other garbage, meaning other household waste except recyclables, hazardous waste, food waste and other garbage. Wet garbage refers to easily decayed biomass waste generated in daily life, and peeled chestnut shells belong to one of these categories, so peeled chestnut shells are also wet garbage rather than dry garbage.
