In recent years, many tea drinkers have become aware of an unsettling fact, that their daily cup of tea may be delivering more than just warmth and relaxation. It’s now understood that microplastics (tiny plastic particles less than 5mm in size) are present in many conventional tea bags, potentially posing a risk to both our health and the environment.
What Are Microplastics?
Microplastics are small fragments of plastic that result from the breakdown of larger plastic products or from the manufacturing of products like textiles, cosmetics, and even tea bags. When these tiny particles are released into the environment, they don’t biodegrade, meaning they accumulate in the soil, waterways, and eventually, the food chain.
In recent years, studies have found microplastics in seafood, bottled water, and now tea. One study shows a single plastic tea bag at brewing temperature can release around 11.6 billion microplastic particles and 3.1 billion nanoplastic particles into just one cup of tea. Although research is ongoing, scientists are increasingly concerned about the potential health risks of ingesting microplastics and their long-term environmental impact. These particles are invisible to the naked eye, but they’re ingested with each sip, leading to concerns about potential health risks.
How Microplastics Get Into Tea Bags
Traditionally, tea bags were made from natural materials like silk or paper. However, as production methods evolved, many manufacturers began using plastic-based materials, particularly in the sealing and reinforcing tea bags. Some tea bags, particularly pyramid-shaped or “silken” bags, are made from plastic materials such as polyethene terephthalate PET or polypropylene - (A plastic that's often used to heat-seal tea bags to prevent them from falling apart) which releases microplastic particles when exposed to hot water.
Why Microplastics in Tea Are a Concern
The ingestion of microplastics is a growing concern for several reasons:
- Health Implications: Although research on the effects of microplastics on human health is still developing, early findings are concerning. Microplastics can carry toxins, and there’s potential for these particles to accumulate in the body over time, leading to inflammation or other unknown health effects.
- Environmental Impact: When microplastics from tea bags end up in compost or landfill, they contribute to plastic pollution. These particles enter the soil and waterways, where they are difficult to filter out and ultimately harm ecosystems and wildlife.
- A Deceptive Experience: Many tea lovers choose tea bags for convenience, assuming they’re as natural as the tea leaves they contain. However, the reality is that some of these bags can be up to 25% plastic, leaving unsuspecting consumers ingesting microplastics with each cup.
How to Enjoy a Plastic-Free Cup of Tea
Switching to plastic-free tea options is an easy and effective way to protect yourself and the environment from microplastic pollution. Here are a few ways to start enjoying a safer, more sustainable cup of tea:
- Opt for Loose Leaf Tea: Loose-leaf tea is one of the simplest ways to avoid plastic in your brew. By choosing loose tea leaves, you eliminate the need for a bag. To make the switch even more eco-friendly, consider using a Loose Leaf Tea Strainer—a reusable, durable alternative to disposable tea bags that allows the flavour of the tea to infuse fully without any plastic waste.
- Look for Plastic-Free Tea Bags: Some brands have recognised the demand for plastic-free tea bags and now offer products made from compostable plant fibres. Be sure to check the packaging and certifications to confirm that the bags are 100% plastic-free.
- Reusable Infusers and Strainers: Reusable tea infusers or stainless steel strainers are excellent alternatives for tea drinkers who prefer a no-fuss brew. The ecoJiko Stainless Steel Strainer is a great option, providing an easy way to steep loose-leaf tea without contributing to plastic waste.
- Make Your Tea Blends: If you’re feeling adventurous, you can make your tea blends using dried herbs, flowers, and tea leaves. By doing so, you have full control over the ingredients and can package them in eco-friendly containers or jars, completely avoiding plastic packaging.
Practical Steps to Avoid Microplastics in Your Kitchen
Switching to plastic-free tea bags is just one step toward reducing your exposure to microplastics. Here are a few other eco-friendly products that can help you avoid plastic and help the environment:
- Bamboo and Stainless Steel Utensils: Plastic kitchen tools can shed microplastics over time. Instead, opt for sustainable plastic-free kitchen utensils. A great alternative could be changing from a plastic chopping board to a Beech Wood chopping board which is durable, eco-friendly, and removes any risk of microplastics getting into your food.
- Plastic-Free Cleaning Supplies: Microplastics can also come from synthetic cleaning sponges and cloths. Consider switching to natural cleaning tools and swap your plastic scrubbing brush for a Sustainable Bamboo Pot Scrubber. They are biodegradable and plastic-free, helping to keep your kitchen as eco-friendly as your tea.
- Stainless Steel Water Bottles and Glass Containers: Avoid plastic bottles and containers that can leach microplastics by choosing stainless steel, or bamboo alternatives. We have a range of suitable bamboo containers such as a Sustainable Bamboo Spice Container and our Stainless Steel Lunchboxes. These materials are long-lasting, easy to clean, and free from microplastics, making them a healthier choice for storing beverages and food.
Why Plastic-Free Tea Matters
Switching to a plastic-free tea routine might seem like a small action, but it has far-reaching implications. By choosing sustainable tea bags or loose-leaf options, you’re:
- Supporting a Healthier Body: Reducing microplastic exposure helps protect against potential health risks associated with ingesting plastics and the toxins they carry.
- Protecting the Environment: Less plastic waste means fewer microplastics in the soil, rivers, and oceans, preserving ecosystems and protecting wildlife from the harmful effects of plastic pollution.
- Encouraging Industry Change: By supporting brands that prioritise plastic-free products, you’re encouraging the industry to shift toward more sustainable practices.
By educating ourselves and making conscious choices, we can make a positive impact on our health and the planet. Start with small changes, like opting for plastic-free tea bags or loose-leaf tea, and explore eco-friendly alternatives for everyday products.
