Co-op announces initiative to reduce Britain’s plastic waste

The war on plastic waste is extending to the UK’s favourite beverage, with a major retailer in the final stages of developing a fully biodegradable paper teabag that does not contain plastic.

The Co-op is to make its own-brand Fairtrade 99 teabags free of polypropylene, a sealant used industry wide to enable teabags to hold their shape, and the guilt-free brew is due to go on sale by the end of the year.

The scale of the problem is huge. According to the trade body the UK Tea and Infusions Association, teabags account for a whopping 96% of the 165 million cups of tea drunk every day in the UK. Anti-plastic campaigners have been appealing to consumers to use loose tea or “greener” options such as Japanese-style “pyramids” made of 100% compostable corn starch, but these are more expensive than mainstream mass-produced teabags.

The Co-op, which sells 4.6m boxes of tea a year (367m teabags) has joined forces with its tea supplier, Typhoo, and Ahlstrom-Munksjö – specialists in sustainable fibre solutions – to develop a method of heat-sealing bags to eliminate the more widely used plastic seal.

The biodegradable bag will undergo rigorous testing next month and could be on shelves later this year. It is intended to be rolled out across the Co-op’s entire own-label standard tea range and will be fully compostable in food waste collections.

“Many tea drinkers are blissfully unaware that the teabag from their daily cuppa is sealed using plastic,” said Jo Whitfield, chief executive of Co-op Food. “Even though it’s a relatively small amount, when you consider the 6bn cups of tea that are brewed up every year in the UK, we are looking at around 150 tonnes of polypropylene – that’s an enormous amount of accumulated plastic waste that is either contaminating food waste compost collections or simply going to landfill.”

But the UK Tea and Infusions Association warned of higher prices for consumers. A spokesman said: “The UK tea industry has been experimenting with non-plastic sealing methods, but those methods are costly. The raw material cost and upgrades to machinery would increase the cost of a bag by about eight times if we were to move to a non-plastic sealing procedure now. We know that a significant price rise would have a severely negative effect on sales and seriously reduce the income of farmers from some of the poorest tea-growing regions of the world.”
