Why Is There Plastic In My Tea Bag?

We look at brands to avoid and eco-friendly alternatives.

As the UK wakes up to the damage single-use plastic is wreaking on our planet, it seems even the most unexpected of everyday British joys are to blame, such as the humble cup of tea. This is because a number of the UK’s most popular tea bag brands use polypropylene, a sealing plastic, to fasten the tea bags and ensure that they hold their shape.

While a handful of brands have announced they will be ditching plastic for good - first Co-op’s own brand and later PG Tips - the nation’s excessive tea habit still contributing to our plastic pollution problem. Tea drinkers in the UK get through 60.2 billion cups of tea each year, with 96% of brewed using a tea bag, according to the UK Tea and Infusions Association

Louise Edge, senior oceans campaigner at Greenpeace UK, told HuffPost UK: “There is no reason why enjoying a cuppa should mean adding to our plastic waste problem. Plastic-free alternatives already exist.”

We spoke to various brands to find out where to get your tea bags if you’re keen on a plastic-free brew. But remember to check whether the products are biodegradable, which means it breaks down, or compostable, which means it can be used as nutrient-rich soil - the two are often used interchangeably and are not the same.

Ones To Avoid

Tetley has confirmed to HuffPost UK that its tea bags contain polypropylene plastic, but it is working on ways to be more sustainable.

Meanwhile both Twinings’ ‘heat-sealed’ and ‘string and tag’ ranges include plastic as well. 

Eco-Friendly Alternatives

If you’re partial to a Twinings tea, fear not, its Loose Leaf pyramid tea bag range contains no plastic and is fully biodegradable, including tags. 

Pukka Herbs’ tea bags are completely plastic-free and stitched together with organic cotton. All tea bags, including tags, are fully-compostable. 

PG Tips has announced it is ditching plastic from its tea bags in place of a new plant-based material that is 100% renewable and biodegradable.

When it comes to Teapigs, things aren’t so straight forward. Its tea bags are compostable, but only when put into food waste so they can be broken down industrially through local council recycling schemes. Basically, they won’t break down fast enough if you try to compost at home. However, you know the plastic bag the tea bags are stored in? The brand recently started using a material called ‘Natureflex’, which is made from wood-pulp and can be composted at home. 

Earlier this year Co-Op announced its plans to ditch the plastic strip that seals its own-brand 99 tea bags, replacing it with a new heat-sealing process. The bag will be on the shelves later this year. 

For more supermarket ranges check out Aldi’s premium Specially Selected range and Waitrose’s Duchy range, which is biodegradable. 

HuffPost UK also reached out to Lidl, Tesco and Asda regarding the recommended disposal of their own-brand tea bags, but had not received a response at the time of publication.
