A Taiwanese-designed biodegradable bottle cap that hermit crabs can use as their homes won gold at this year’s World Innovation and Invention Competition in South Korea, as Taiwan ranked first overall, according to the results, which were announced yesterday.
The competition attracted 243 entries from 12 countries, including Taiwan, which submitted 51 inventions, as well as Canada, Indonesia, Malaysia, the Philippines, South Korea, Thailand and Turkey.

Made of plastarch material — a biodegradable thermoplastic resin that is derived from corn starch — the cap can serve as a home for hermit crabs before it decomposes.
Many hermit crabs are forced to use bottle caps as homes, as people remove the seashells the crustaceans typically use from beaches, Chen said, adding that they can die without suitable shells to live in.
The team designed a waterproof layer in the cap made with edible wax, which would not harm sea birds if ingested by accident.
Chen said he hopes the caps raise awareness about conservation.
The team has already obtained a patent for the cap.
Another gold-winning invention was a method for recycling lithium-ion batteries used in electric vehicles, conceived by Da-Yeh University environmental engineering professor Lee Ching-hwa (李清華) and graduate students Huang Yu-jui (黃于睿) and Shih Chen-hsuan (施辰宣).
The team used hydrometallurgical techniques to recycle valuable metals such as lithium, aluminum, cobalt, nickel, manganese and copper from the batteries of scrapped vehicles to promote a circular economy and curb environmental pollution, they said.
They have filed a patent for the project, which has been awarded a grant from the National Science and Technology Council.
Other gold-winning inventions included an interactive picture book created by a team led by Yen Ying-hung (閆嬰紅) at Asia Eastern University of Science and Technology; a smart pressure testing system for table tennis players devised by Tsai Meng-hsiun (蔡孟勳) and his students at National Chung Hsing University; and a fast decanter invented by Liu Wei-wu (劉緯武) and his students at Hungkuo Delin University of Technology.
EVA Airways today confirmed the death of a flight attendant on Saturday upon their return to Taiwan and said an internal investigation has been launched, as criticism mounted over a social media post accusing the airline of failing to offer sufficient employee protections. According to the post, the flight attendant complained of feeling sick on board a flight, but was unable to take sick leave or access medical care. The crew member allegedly did not receive assistance from the chief purser, who failed to heed their requests for medical attention or call an ambulance once the flight landed, the post said. As sick
A drunk woman was sexually assaulted inside a crowded concourse of Taipei Railway Station on Thursday last week before a foreign tourist notified police, leading to calls for better education on bystander intervention and review of security infrastructure. The man, surnamed Chiu (邱), was taken into custody on charges of sexual assault, taking advantage of the woman’s condition and public indecency. Police discovered that Chiu was a fugitive with prior convictions for vehicle theft. He has been taken into custody and is to complete his unserved six-month sentence, police said. On Thursday last week, Chiu was seen wearing a white
The Taichung District Court yesterday confirmed its final ruling that the marriage between teenage heir Lai (賴) and a man surnamed Hsia (夏) was legally invalid, preventing Hsia from inheriting Lai’s NT$500 million (US$16.37 million) estate. The court confirmed that Hsia chose not to appeal the civil judgement after the court handed down its ruling in June, making the decision final. In the June ruling, the court said that Lai, 18, and Hsia, 26, showed “no mutual admiration before the marriage” and that their interactions were “distant and unfamiliar.” The judge concluded that the couple lacked the “true intention of
EVA Airways, one of the leading international carriers in Taiwan, yesterday said that it was investigating reports that a cabin crew manager had ignored the condition of a sick flight attendant, who died on Saturday. The airline made the statement in response to a post circulating on social media that said that the flight attendant on an outbound flight was feeling sick and notified the cabin crew manager. Although the flight attendant grew increasingly ill on the return flight, the manager did not contact Medlink — a system that connects the aircraft to doctors on the ground for treatment advice during medical
