The firm uses an already-established process to turn the waste into a range of useful products. It has won this year's Converge Challenge, an initiative set up to help some of Scotland's new entrepreneurs.

The difficulty in recycling most takeaway coffee cups was highlighted by TV chef Hugh Fearnley-Whittingstall in a documentary three years ago. The vast majority of cups are incinerated or end up in landfill because of difficulties separating the paper and plastic in their inner lining which makes them leak and heatproof.

The cups can be broken down into gas and bio-oil which can be used to produce energy. It also leaves behind a carbon-rich solid, known as CreChar which can also be used as a fertiliser. 

The firm is moving on to commercial testing and hopes to have a demonstration production plant up and running in Edinburgh next year...
