"Reclaiming waste is a hot trend in food and drink, and beauty isn't far off the pace. Exhibit A? UpCircle, a UK-based company, launched in 2016, which is adding moisturisers made with repurposed olive and avocado stones to its range this year.

Now stocked in Boots, UpCircle is already on track to save more than 1000 tonnes of coffee grounds (used to make scrubs and serum) from going to landfill in the next 5 years. "We've proven that the circular economy approach is possible on a mass scale," says co-founder Anna Brightman. "If two siblings can achieve this so quickly, I see no reason why the industry as a whole can't begin transforming its attitude to waste."
