Pyramid tea bags are often made from plastic or nylon and are not compostable or biodegradable. However, some companies are making efforts to create plastic-free pyramid tea bags using biodegradable plant-based materials such as Soilon, derived from cornstarch, or plant fibres from sugar cane and corn. Concerns have been raised about the presence of microplastics in tea bags, with studies finding that premium tea bags may release billions of microplastic and nanoplastic particles into hot water. These particles are invisible to the naked eye and have been detected in drinking water, although the health risks are currently deemed low. The impact of plastic tea bags on the environment is also a concern, with non-biodegradable bags contributing to landfill waste.

Some pyramid tea bags are made from plastic or nylon
The presence of plastic in tea bags is often due to the use of plastic mesh to hold the bag in a pyramid shape, which is claimed to enhance the infusion of tea leaves. However, some companies, such as Tease, offer plastic-free pyramid tea bags made from plant fibres derived from sugar cane and corn/abaca. These bags are also free from staples, glue, and bleach, making them more environmentally friendly.
Another alternative is biodegradable tea bags made from polylactic acid (PLA), a bioplastic designed to break down in industrial and municipal composting facilities under controlled conditions. However, studies have shown that the breakdown of PLA can negatively impact earthworms, highlighting potential ecological risks.
It is worth noting that not all pyramid tea bags contain plastic, and some companies, like Canton Tea, use biodegradable plant-based materials like Soilon, derived from cornstarch. These tea bags are claimed to break down into water, carbon dioxide, and biomass within 8-12 weeks when disposed of in council food waste bins.
Overall, while some pyramid tea bags are made from plastic or nylon, there are environmentally friendly and plastic-free alternatives available in the market. Consumers concerned about their health and environmental impact can opt for these sustainable options.

Plastic pyramid tea bags can release billions of microplastic particles into water
The study specifically examined premium tea bags made with plastic mesh to hold the bag in a pyramid shape, which is claimed to improve the infusion of tea leaves. Plastic pyramid tea bags are often made from nylon or other petroleum-based compounds, which can melt in the microwave and release chemicals into the tea. These tea bags are not biodegradable or compostable and can take a long time to break down, even in council compost treatment cycles.
Some companies, such as Tease, Canton Tea, and Leaf Infuser, offer plastic-free pyramid tea bags made from biodegradable plant-based materials like Soilon (derived from cornstarch), sugar cane, and corn/abaca fibres. These tea bags are environmentally friendly and do not release microplastics into the water. However, they may take longer to break down in a domestic compost heap and are recommended to be disposed of in council food waste bins.
To avoid the potential release of microplastics into tea, consumers can choose loose-leaf tea sold without packaging or tea packaged in paper tea bags. Composting tea bags can also help reduce their environmental impact, although only about 70% of tea bags are currently compostable.

Plastic tea bags are not biodegradable or compostable
Plastic tea bags are a growing environmental concern. The plastic in tea bags is usually found in the form of polypropylene plastic, nylon, or other petroleum-based compounds. These materials are often used to seal the tea bags and prevent the tea leaves from escaping. However, they are not biodegradable or compostable, which means they can take hundreds of years to break down in landfills.
The presence of plastic in tea bags has also raised concerns about the potential health risks associated with consuming microplastics. A study published in the journal Environmental Science and Technology found that a single plastic tea bag released approximately 11.6 billion microplastic and 3.1 billion nanoplastic particles into hot water. These particles are invisible to the naked eye and can potentially be consumed unknowingly. While the World Health Organization (WHO) has stated that microplastics in drinking water do not currently pose a significant health risk, they have called for further research on the topic.
Some tea companies have started offering plastic-free and biodegradable alternatives to traditional tea bags. These tea bags are often made from plant-based materials such as sugar cane, corn/abaca fibres, or a biodegradable material called Soilon, which is derived from cornstarch. These biodegradable tea bags are designed to break down naturally in composting conditions, leaving no harmful residues. However, it is important to note that some biodegradable tea bags are specifically designed to break down in industrial and municipal composting facilities and may not break down effectively in a domestic compost heap.
Consumers who are concerned about the environmental and health impacts of plastic tea bags can opt for loose-leaf tea or tea packaged in paper tea bags. Using a stainless steel infuser or DIY brew bags made from sustainable wood pulp are also environmentally friendly alternatives to plastic tea bags. By making conscious choices, consumers can reduce their plastic waste and minimize their impact on the planet.

Plastic-free alternatives are made from biodegradable plant-based materials
Plastic-free tea bags are usually made from biodegradable plant-based materials such as maize or corn starch. These plant-based materials function in the same way as polypropylene, a type of plastic. Bioplastic can also be derived from genetically modified (GMO) maize, although these are not permitted in organic tea bags.
Some tea brands that offer plastic-free and biodegradable tea bags include Clipper Teas, Teapigs, PG Tips, Tielka, and Abel & Cole. Clipper Teas, for example, uses a non-GM bio-material made from plant cellulose, known as PLA or bioplastic. PLA is fully biodegradable and unlike oil-based plastics, it won't contaminate your compost heap with petrochemical residue. PG Tips also announced in 2018 that they were transitioning to a fully biodegradable, plant-based material for their pyramid tea bags. Teapigs tea bags are made from corn starch and will break down in 12 weeks if put in with food waste collection.
In addition to corn starch, other plant-based materials used to make plastic-free tea bags include abaca, cellulose fibres, and polylactic acid (PLA). For instance, Traditional Medicinals' tea bags are made from sustainably harvested abaca leaf fibres and wood pulp, while Tielka's Fair Trade tea bags are made from an unspecified plant-based fabric.
Some tea bags are also sealed with a blend of cellulose fibres (wood pulp), abaca, and a small amount of acrylic binder to prevent microwave bursting, and poly-amide-epichlorohydrin (PAE) as a wet strength plastic resin. However, it is important to note that while biodegradable plant-based plastics exist, studies have shown that they can be toxic to human health. As an alternative, consumers can opt for loose-leaf tea or reusable tea infusers made from materials such as stainless steel.

Plastic-free pyramid tea bags are available from some manufacturers
Leaf Infuser's pyramid tea bags are also plastic-free and are made from 100% natural plant-based PLA tea bag paper. However, it is worth noting that PLA is designed to break down in industrial and municipal composting facilities under specific conditions, and there are only a few such facilities in some countries. For example, the manufacturer EatRite Australasia Pty Ltd, based in Australia, states that their tea bags are made with unbleached paper and no polymers or plasticizers.
Some other manufacturers have made efforts to reduce the amount of plastic in their tea bags. For instance, Lyons' tea bags are now all plant-based and made from a blend of natural fibres, including a small amount of plastic fibres. They state that the amount of plastic used is minimal, making up less than 5% of the tea bag paper, and that their tea bags are designed to break down naturally in composting conditions, leaving no harmful residues.
It is important to note that, while plastic-free pyramid tea bags are available from some manufacturers, many pyramid tea bags are made from plastic or nylon and are not compostable or biodegradable. A study published by the journal of Environmental Science and Technology found that a single plastic tea bag released about 11.6 billion microplastic and 3.1 billion smaller nanoplastic particles into hot water. Therefore, it is essential to choose plastic-free tea bags from reputable manufacturers to reduce the impact on the environment and potentially on health.
