1 . A 23-year-old British woman has invented a product that she hopes will one day take the place of single-use plastic. The new product is made by combining fishing waste and algae （藻类）.

Lucy Hughes created the material, called MarinaTex, for her final year project at the University of Sussex. She continued her research after she left the university.

On November 13, the James Dyson Foundation announced that Hughes was the international winner of the 2019 James Dyson Award for design.

MarinaTex is edible, meaning it can be eaten without danger. Hughes says it also is strong and stable. But unlike plastic, MarinaTex breaks down in four to six weeks under normal conditions and does not pollute the soil.

The inventor said she is concerned about the growing amounts of plastics in ocean waters. She noted one report that there would be more plastic than fish in the world's oceans by the year 2050. The United Nations estimates that 100 million tons of plastic waste has already been left in the oceans.

Hughes also was investigating ways to reduce the amount of waste from the fishing industry. The industry produces an estimated 50 million tons of waste worldwide each year, UN officials say.

Hughes told Reuters that she was "trying to work out how I could use the waste stream and add value to that waste." Examining fish parts left over from processing helped to give her the idea for a material that was useful and did not harm the environment.

To create a strong material, Hughes added the molecule chitosan, which comes from sea creatures like crabs, and agar, a material from red algae.

After months of testing, Hughes produced a strong, flexible sheet that forms at temperatures below 100 degrees Celsius.

Inventor James Dyson said that MarinaTex is "stronger, safer and much more sustainable" than the plastic polyethylene. It is also easier to break down than other possible replacement products for polyethylene, the material that single-use plastic bags are made of.

Hughes will receive about $41,000 in prize money as the first place winner of the James Dyson Award. She told Reuters that she plans to use the money to better develop the product and ways to mass produce it.
