This year's winner of the James Dyson award made a nifty single-use bioplastic out of organic fish waste.
Lucy Hughes started with the idea of utiltising an existing waste stream as a resource for the plastic, and turned to organic fish waste from the fish processing industry - it's plentiful and ongoing, with over 170,000 tons of the stuff is produced annually, so there's not going to be a shortage of it anytime soon.
MarinaTex is made from a combination of the fish waste would otherwise be incinerated or sent off to landfill site somewhere, and locally sourced redalgae.
Once you chuck it onto the compost heap, it'll decompose in around four to six weeks, making it ideal for single-use packaging.
"Young engineers have the passion, awareness and intelligence to solve some of the world’s biggest problems… MarinaTex elegantly solves two problems: the ubiquity of single-use plastic and fish waste. Further research and development will ensure that MarinaTex evolves further, and I hope it becomes part of a global answer to the abundance of single use plastic waste,” said Sir James Dyson himself.
