Macleans magazine had an article earlier this month about tea bag food waste in Britain. Having recently developed a tea habit on that fair island, and being generally concerned with food and waste and composting, I've got a vested interest in this.
Britain's 62 million residents drink 165 million cups of tea per day. (Fun fact! That's 2 ⅔ cups per person.) This is a lot of tea, and it produces a lot of waste: tea bags add 370 000 tonnes of waste to landfills per year.
