Interviewees: Lucy Hughes, Eco-inventor & Mat Hunter, Co-CEO, Plus X
A graduate from the University of Sussex has developed a transparent film, made from fish waste, which could help fight plastic pollution.
Lucy Hughes created 'MarinaTex' as part of her product design degree.
It's made from the proteins in fish scales and skins, waste products of the fishing industry, and can be composted after use.
It's being hailed as a 'breakthrough' invention which could drastically reduce our reliance on single-use plastic packaging.
It's won Lucy Hughes the James Dyson Award which celebrates, encourages and inspires the designers of new problem-solving ideas.
Lucy has also won a prize from Plus X in Brighton, which will give her mentoring and a workspace for six months.
It took Lucy around 100 attempts to perfect the recipe, with much of the work done in her own kitchen.
It is predicted that in 30 years there could be more plastic in our oceans than fish by weight. Lucy hopes to change that.
