An easily biodegradable(可生物降解的) material that could be “part of a global answer” to singleuse plastic pollution has won its inventor, British designer Lucy Hughes, the international James Dyson Award.
Hughes' Marina Tex bioplastic is strong and flexible, making it a possible alternative for singleuse packaging such as bags and sandwich wrappers. Its key ingredients are fish scales and skin, so it can break down in home food waste or compost bins.
Hughes created Marina Tex for her finalyear project in the product design course at the University of Sussex. She had set out to create something using waste rather than unused materials, which led her to the UK's fishing industry. She ran more than 100 experiments to improve the bioplastic mixture, mostly using the kitchen stove in her student accommodation.
The fish scales and skin removed during processing usually end up burnt or buried in landfill. And with “about 500，000 tonnes of such waste produced by the country's fisheries annually”， it seems possible that Marina Tex could be used largely in industrial production. The material is lowenergy to produce and doesn't consume the earth's natural resources considering it's based on existing waste. It is also strong, boasting a higher tensile(可拉伸的) strength than the current material most commonly used for plastic bags.
British inventor James Dyson, who every year selects the grand prize winner in the international student design competition that bears his name, said that the material had the potential to replace traditional singleuse plastics. “Marina Tex elegantly solves two problems: the ubiquity(无处不在) of singleuse plastics and fish waste，” he said. “Further research and development will ensure that Marina Tex evolves further, and I hope it becomes part of a global answer to the abundance of singleuse plastic waste.”
