Loose leaf teas have become more and more popular as people seek to avoid microplastics and trend towards more environmentally friendly alternatives. We are here to uncover the mystery around microplastics in tea bags as well as answer your questions about biodegradable tea bags.
Are Tea Bags Biodegradable?
Are all tea bags biodegradable? The answer is no. Not all tea bags break down naturally, as different companies use different materials with varying commitments to sustainability.
While the tea inside tea bags is typically biodegradable, the outer packaging can be problematic. Many conventional tea bags contain plastic fibers, preventing them from fully breaking down in compost or soil. This leads us to the next question:
What are tea bags and tea sachets made from?
Tea bags and sachets come in all shapes, materials, and sizes. The first tea bags were made from gauze! Today, tea bags are made from paper, plastic, or nylon. This is partly because these types of materials can withstand hot water while also showing you the tea inside.
“Pillow Style” tea bags (left) are tea bags made of paper and woven plastics. String tea bags (middle) are the most common type of tea bag. These are made of polypropylene fibers and can also contain plastic or plastic foil. Finally, “silken” sachets (right) are also made of plastic (typically) but have more recently been made out of other materials such as corn or other plant-based materials.
Because of these plastic components, many tea bags do not biodegrade fully, contributing to landfill waste and ocean pollution as they break down into microplastics.
Avoiding Microplastics in Tea Bags & Sachets
Concerns over microplastics in tea bags have been growing, and recent studies confirm the risks. A 2023 study published in Environmental Science & Technology by researchers at McGill University found that steeping a single plastic-based tea bag in hot water can release billions of microplastic and nanoplastic particles into your tea. Researchers warn that long-term consumption of these particles may contribute to inflammation, gut imbalances, and respiratory issues.
This highlights the importance of choosing truly biodegradable and plastic-free alternatives.
