It might not be everyone's cup of tea, but the leftover food in your fridge could be your key to a environmentally-friendly drink with a difference.
Shoppers have been challenged to change their wasteful ways and create fruit and veg concoctions with healthy ingredients that might otherwise end up as landfill.
And according to Love Food Hate Waste, these liquid leftovers could even save you £200 a year.
The Liquid Greens Machine visited Victoria Square shopping centre yesterday to persuade the public that beetroot, spinach and celery can actually make a delicious drink.
While vegetables might not be the first thing you think of when it comes to juice recipes, organiser Sally Holyhead said people had been keen to give them a go.
"You might think that people would immediately go for the fruit smoothies but you would be surprised. It's been a fairly mixed take-up all morning," she said.
It might have contained beetroot, but the 'Cool as a Cucumber' juice was one of those drinks that raised eyebrows – in a good way.
Musician David Jackson's verdict was: "It's cool and actually really refreshing and I would try it again."
Amanda Corless and Lizzie Riley both went for the 'Use Me Up Honey' smoothie, with oranges, honey, and kiwi fruit and banana. Afterwards they pledged to plan their food shopping better and to use leftovers.
