Are Tea Bags Compostable? (And Biodegradable)

Tea bags, the evolved method of packaging our tea, are one of the most innovative packaging wonders – we’ve found a way to enjoy fresh tea from any part of the world. Tea bags are not only great for packaging tea but will also preserve the contents and keep them fresh for you.

Finally, you can trust that a tea bag will leave no mess before, during, and after preparation. Well, the health benefits, refreshing qualities, and these other advantages we’ve mentioned certainly explain why upward of 159 million Americans consume tea daily.

Essentially, our primary concern is with the extract we can derive from the leaves contained in the bag. As such, when we finish extracting it by brewing it in a hot mug, the bag becomes useless. Or does it?

This blog post will show you alternate uses of tea bags and how these are better and safer options than throwing them away. Keep reading!

Can You Compost Tea Bags?

In society today, there are many methods of disposing of our waste. One of them is composting, and this serves many purposes. For instance, it reduces the amount of waste we leave behind, thereby creating a uniform disposal method. In addition, composting also provides a nutritious meal for our plants.

If you enjoy gardening and do it often, and are also a tea lover, then you may find the thought of composting tea bags occasionally running through your mind. Well, you can compost tea bags, but not all.

Tea bags are made of tea leaves that have been packed into a slightly porous material that holds the bag together. You get your tea by infusing the sachet in water and waiting for the water to significantly dilute the leaves and extract the fragrances and flavors you want.

Most brands use filter paper, a type of paper made from abaca. This is a safe option, as abaca itself is the leaf stalk of a banana plant found in the Philippines.

However, some brands also use silk, nylon, and plastic, or “silken” tea bags. These materials are non-compostable because they won’t break down fast, unlike biodegradable materials.

Now, while you can’t compost all tea bags, you sure can compost the bag’s components. It’s as easy as opening it up and pouring it into your compost bin, then finding environmentally sensitive ways to dispose of the pack.

However, if you consume a brand that uses biodegradable materials for the bags, don’t hesitate to drop the bag in your compost pile. It’ll also add to the nutrients for your plants.

Most importantly, it’s best to avoid leaving the tea bags in an exposed area, such as a landfill. This is because it can adversely affect the environment while it slowly rots.

Can You Put Tea Leaves in the Compost?

We interact with tea bags to extract the tea fragrance and flavor from the leaves packed in them. After infusing for the designated timeframe, we can remove the tea bag and dispose of it, as it’s now become useless.

But again, this isn’t true, as you can compost the tea leaves instead. Depending on the tea brand, you may have to remove the leaves and compost them alone.

Now, we’re confident it’ll interest you to know that there are several reasons you’ll benefit from composting your tea leaves. First, because the leaves go in your teapot before they go in the compost pile, they already have all the moisture they need to break down properly.

Tea leaves qualify as nitrogen-rich materials, so they’ll serve as the balance between these materials and the carbon-rich ones found in most compost piles. Let’s also consider the effects the tea leaves will have on your plats and soil, considering that they’re nitrogen-rich materials.

For one, tea leaves will increase the rate of nitrogen retention in your soil. Subsequently, the concentration of nitrogen increases, ultimately resulting in faster growth and sturdy roots that can withstand extreme temperatures. So, you see how important those tea leaves are – you can save them from improving the quality of your gardening experience.

Are Tea Bags Biodegradable?

Most of us are more familiar with tea bags that are made from abaca – they’re a filter-like paper, as we’ve mentioned earlier. These packaging materials are eco-friendly; they’re made from natural materials and have no added components.

As such, if you compost them or dispose of them in the garbage can, they break down in a short time. Most times, it takes about 2 to 6 weeks for a full breakdown. When this happens, these bags can also increase the nutrients in the soil.

On the other hand, tea bags made from silk, nylon, and plastic should never go in a compost bin. They should also never go in your compost pile at home.

Instead, you’ll have to find alternate ways to dispose of these tea bags. Our go-to option is recycling, but even that method is subject to some conditions. For instance, you can’t recycle materials other than paper or bio-plastic. Essentially, this means if the tea bag is made from mixed materials, you can’t recycle it.

In this case, you can empty the bag’s content into your compost pile and creatively dispose of the silken bags.

Are Twinings Tea Bags Compostable?

Twinings tea is one of the best tea brands around. It’s available in many flavors and blends, and there’s almost a certainty that you’ll enjoy one or all of the available flavors. If we’ve predicted correctly, you likely also have a couple in your pantry.

Well, beyond consuming this delicious tea, have you considered how you’ll dispose of the bags? This brand has stated that the tea bags contain polypropylene, a plastic that can’t be recycled when combined with other materials. Please note that this material is considered safe for human consumption, so you don’t need to worry about your health.

Polypropylene also isn’t compostable. Ordinarily, most kitchen waste can go in a compost bin or pile, but one that contains a material such as this should be disposed of through other means.

Polypropylene won’t break down fast, unlike the materials that should be in a compost pile. Instead, it takes about two to three decades for it to decompose. During that period, your plants or soil aren’t getting any nutrients. You’ll be exposing them to the toxicity that leaches from materials like this.

This material isn’t good for the environment, but it has little to no effect when you consume products manufacturers have packaged it with. On a final note, Twinings Tea Brand has mentioned that it’ll make tea bags that are biodegradable going further.

Now, while you certainly can enjoy a hot cup of your favorite Twinings Tea Strong and Malty, you’ll have to find an environmentally friendly way of disposing of your waste. We recommend several arts and crafts such as murals, inner lining, or whatever creative idea you can cook up.

Are Tetley Tea Bags Compostable?

For any material to qualify as compostable, it must be capable of breaking down within the shortest while. In addition, its decomposition must serve one or two purposes – such as providing nutrients for plants, providing aeration for the soil, or de-clumping it.

Many of our household waste are compostable, and when they aren’t, we can recycle them. For this reason, finding a compost bin in your community won’t be difficult. Alternatively, you may have your compost pile for your kitchen waste at home.

Typically, the contents of a compost pile should be biodegradable; that is, they must break down within the shortest period. Ordinarily, tea bags made from filter paper can go in the compost pile, as they’re chemical-free. They’ll also break down fast.

However, Tetley has revealed that their tea bags contain a small amount of plastic to help the bags remain sealed until we have no use for them anymore. That way, you’ll always have access to fresh tea.

By now, we’re confident you’re aware plastic isn’t biodegradable, so it’s the last item that should be found in your compost pile. So, you can’t compost Tetley tea bags because of this small addition. But again, this brand is currently working on tea bags that’ll be compostable and eco-friendly.

Are Lipton Tea Bags Compostable?

Lipton is one of the oldest and most famous tea brands globally today. More often than not, it’s the go-to tea brand for most households. So, if you consume a significant amount of Lipton tea bags, then you’ll also have a considerable amount to dispose of.

If you have a compost pile in your garden, you may consider composting the used bags. After all, they contain tea leaves that’ll benefit your plants.

Well, you’re right to a reasonable degree. You can compost Lipton tea bags, but not all. This brand produces two types of tea bags. The manufacturers make the first type from unbleached paper and TCF, both non-threatening materials to the environment.

On the other hand, the other type of tea bag contains polyethylene terephthalate, the material that makes these batches non-biodegradable and therefore non-compostable.

So, before you compost any Lipton tea bag, ensure it’s not made from the latter material.

Can You Drink Expired Tea Bags?

Finding a set of your favorite tea bags can be exciting, but your mood may dampen when you think about the expiry date. After all, nothing seems to be externally wrong with the tea bags, but they’ve been in storage for way too long.

Now, tea bags typically don’t go bad. They only have an expiry date to give you an idea of the production timeframe. When tea exceeds its shelf life, it won’t spoil or result in stomach troubles. However, you’ll notice a significant reduction in the quality, taste, and fragrance.

Tea bags have been produced to last long years on your shelf. They’re dried leaves so that they can be preserved for much longer than your average foods. Unless they contact water, they won’t rot or spoil.

Tea bags don’t expire, despite having an expiration date attached. If you are skeptical about the condition of the tea, you can examine it to see if mold has started growing on it. We recommend that you examine any abandoned tea bags for growing mold. It’s at this point that tea becomes unconsumable.

But again, if the tea bags have just exceeded their expiry date, or maybe by a ballpark of two years, you can still boil some water and brew a few bags.


As green thumbs, the thought of any material going to waste never occurs. We always find one or two uses for it. For instance, we’ve discovered that tea bags are compostable and biodegradable.

We threw in a few exciting facts about drinking expired tea bags as an interesting side bit. Of course, we trust that you’ll use all this information to make more informed decisions.
