[ti:Inventor Wins Prize for ‘Plastic’ From Fish Waste] [by:www.ljhzhm.tw] [00:00.00]更多聽力請訪問51VOA.COM [00:00.04]A 23-year-old British woman has invented a product she hopes will one day replace single-use plastic. [00:11.88]The new product is made by combining fishing waste and algae. [00:19.16]It could be used to replace plastic bags or containers that people use once and throw away. [00:29.28]Lucy Hughes created the material, called MarinaTex, for her final year project at the University of Sussex. [00:40.26]The Reuters news agency says she continued her research after she left the university. [00:49.80]On November 13, the James Dyson Foundation announced [00:56.03]that Hughes was the international winner of the 2019 James Dyson Award for design. [01:06.60]MarinaTex is edible, meaning it can be eaten without danger. [01:13.40]Hughes says it also is strong and stable. [01:17.73]But unlike plastic, MarinaTex biodegrades in four to six weeks [01:26.22]under normal conditions and does not pollute the soil. [01:32.32]The inventor said she is concerned about the growing amounts of plastics in ocean waters. [01:41.11]She noted one report that there would be more plastic than fish in the world's oceans by the year 2050. [01:52.60]The United Nations estimates that 100 million tons of plastic waste has already been left in the oceans. [02:04.08]Hughes also was investigating ways to reduce the amount of waste from the fishing industry. [02:12.02]The industry produces an estimated 50 million tons of waste worldwide each year, UN officials say. [02:25.36]Hughes told Reuters that she was "trying to work out [02:30.30]how I could use [the] waste stream and add value to that waste." [02:37.92]Examining fish parts left over from processing helped to give her the idea [02:45.37]for a material that was useful and did not harm the environment. [02:53.28]"Why do we need to have hundreds of man-made polymers [02:58.03]when nature has so many already available?" she asked. [03:04.48]To create a strong material, Hughes added the molecule chitosan, [03:10.96]which comes from sea creatures like crabs, and agar, a substance from red algae. [03:20.36]After months of testing, Hughes produced a strong, [03:25.10]flexible sheet that forms at temperatures below 100 degrees Celsius. [03:33.92]Inventor James Dyson said that MarinaTex is "stronger, safer [03:41.71]and much more sustainable" than the plastic polyethylene. [03:47.92]It is also easier to break down, or compost, than other possible replacement products [03:56.28]for polyethylene, the material that single-use plastic bags are made of. [04:04.08]Hughes will receive about $41,000 in prize money [04:11.08]as the first place winner of the James Dyson Award. [04:16.61]She told Reuters that she plans to use the money [04:21.48]to further develop the product and ways to mass produce it. [04:27.64]"Further research and development will ensure that MarinaTex evolves further, [04:35.29]and...becomes part of a global answer to the abundance of single use plastic waste," Dyson said.
