[2020广东茂名检测] A 23-year-ld British wman has invented a prduct. She hpes that it will ne day take the place f single-use plastic. The new prduct is made frm by-prducts f the fishing industry and ther natural ingredients.Lucy Hughes created the material, called MarinaTex, fr her final-year prject at University f Sussex. She cntinued her research after she left the university.
On Nvember 13, the James Dysn Fundatin annunced that Hughes was the internatinal winner f the 2019 James Dysn Award.MarinaTex is edible, and t put it in anther way, it can be eaten withut danger. Hughes says it is als strng and stable. But unlike plastic, MarinaTex breaks dwn in fur t six weeks under nrmal cnditins and des nt pllute the sil.The inventr said she was cncerned abut the grwing amunts f plastic in the ceans. She nted ne reprt that there wuld be mre plastic than fish in the wrld’s ceans by the year 2050.
The United Natins estimates that 100 millin tns f plastic waste have already been left in the ceans.Hughes was als investigating ways t reduce the amunt f waste frm the fishing industry. “The industry prduces an estimated 50 millin tns f waste wrldwide each year,” UN fficials say.Hughes tld Reuters that she was trying t wrk ut hw she culd use that waste stream and add value t that waste. Examining leftver fish parts frm prcessing helped t give her the idea fr a material that was useful and did nt harm the envirnment.
T create a strng material, Hughes added the chitsan ml ecule, which cmes frm sea creatures like crabs, and agar, a substance frm red algae.After mnths f testing, Hughes prduced a strng, flexible sheet that frmat temperatures belw 100°C.Inventr James Dysn said that MarinaTex is “strnger, safer and much mre sustainable” than the plastic plyethylene (聚乙烯). It is als easier t break dwn than ther pssible replacement prducts fr plyethylene, the material that single-use plastic bags are made f.
Hughes wuld receive abut ＄41,000 in prize mney as the first place winner f the James Dysn Award. She tld Reuters that she planned t use the mney t better develp the prduct and wrk ut a strategy fr mass prductin.
