The brewed tea is kitchen waste, because the brewed tea will ferment after a long time. If the soaked tea leaves are dried, they belong to other garbage.
Expired tea belongs to kitchen waste and can be used as fertilizer for plants. If there are potted plants at home, covering them with expired tea residue can promote the growth of plants and make the leaves greener and more shiny.

Characteristics of kitchen waste
Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce stench. After proper treatment and processing, it can be transformed into new resources. Because of its high organic matter content, it can be used as fertilizer and feed after strict treatment, and it can also produce biogas as fuel or power generation. Part of the oil can be used to prepare biofuels.
The illegal collection and recycling of kitchen waste will pose a threat to the environment and residents' health. Classified collection of kitchen waste can reduce the amount of organic matter entering the landfill, reduce the generation of odor and landfill leachate, avoid the adverse effects of excessive water on garbage incineration, and reduce the corrosion of equipment.
