University of Sussex graduate Lucy Hughes used fish waste to create MarinaTex, a compostable alternative to current single-use plastic that has won her this year's UK James Dyson Award.
MarinaTex is made from fish scales and skin — waste products that would usually be buried in landfill or incinerated.
It is translucent and flexible, making it a candidate for single-use packaging such as bags and sandwich wrappers, and importantly, it will break down in home composts or food waste bins within four to six weeks.
