Made from Plastarch – a biodegradable thermoplastic resin derived from cornstarch – the lid acts as a home for hermit crabs before they rot.
Many hermit crabs are forced to use bottle caps as homes, Chen said, because people typically throw seaweed from the beach that the crustaceans use, and without a proper shell to live on, they can die.
The team designed a waterproof coating on the edible wax lid, which will not harm seabirds if accidentally swallowed.
Chen said he hoped the hat would raise awareness about safety.
The team patented the hat.
Another gold-winning invention is a method for recycling lithium-ion batteries used in electric vehicles, devised by Lee Ching-hwa (李清華), professor of environmental engineering at Da-ye University, and graduate students Huang Yu-jui (黃于睿) and Shih Chen-hsuan. . . (施辰宣).
The team used hydrometallurgical techniques to recycle precious metals such as lithium, aluminum, cobalt, nickel, manganese and copper from used vehicle batteries, improving environmental economics and controlling pollution environmental.
They applied for a patent for a project funded by the National Science and Technology Council.
Other gold-winning innovations include interactive picture books developed by a team led by Yen Ying-Hung (閆嬰紅) of the East Asian University of Science and Technology; The Intelligent Pressure Testing System for Table Tennis Players was designed by Tsai Meng-hsien (蔡孟勳) and his students from National Chung Hsing University; and the speed bottle invented by Liu Wei-wu (劉緯武) and his students at Hanguo Dellin University of Technology.
