As an avid tea drinker, do you often find yourself wondering what to do with all those leftover tea leaves? Are used tea leaves general waste that goes to the landfill, or can they be recycled as food waste? Let’s dive in and take a closer look!
Tea Waste Sorting: Are Used Tea Leaves Food Waste?
Waste sorting rules for used tea leaves vary by region and largely depend on local government regulations. In Taiwan, spent tea leaves are mostly classified as “raw food waste” (compostable organic waste), meaning they are organic matter that decomposes naturally and is ideal for composting. Please note! They are raw food waste, not cooked food waste. Cooked food waste is suitable for feeding pigs, whereas tea leaves can only be used for composting and should not be placed in the cooked food waste bin.
Under current (2025) waste management policies in Taiwan, tea leaves are generally treated as recyclable raw food waste. Additionally, tea bags do not count as food waste and must be disposed of as general waste. We recommend checking your local waste sorting guidelines to ensure proper recycling.
What Else Can You Do with Used Tea Leaves Besides Recycling?
Aside from recycling them with waste collection services, used tea leaves actually have quite a few eco-friendly and practical household uses! For instance, dried tea leaves can act as a natural deodorizer—you can place them in the fridge, shoe cabinet, near pet litter boxes, or inside trash cans to absorb odors. They also make great plant compost, providing natural nutrients for your potted plants or home garden. So, you don’t necessarily have to hand them all over to the garbage truck.
Although spent tea leaves are technically “waste” after brewing, they still have plenty of uses around the house. If you have a large amount of tea leaves to dispose of via the garbage truck, simply drain the excess water first, then hand them over to sanitation workers to be recycled as “raw food waste.”
