Two teams of Vietnamese students beat other foreign participants to win the most prestigious prizes of an international environmental protection competition on Tuesday.
The international final round of the ‘Young Environmentalists’ Challenge’ competition was organized online by the International University under the Vietnam National University-Ho Chi Minh City and Deakin University of Australia.
The contest was held to enhance young people’s awareness of environmental issues such as soil, water, and air pollution, as well as pollution from solid wastes.
Nine teams, with members from Vietnam, Malaysia, and Sri Lanka, competed in Tuesday’s final round.
Among that, Garyy Lee, K.E.L, and Peach and Psss represented Vietnam after finishing in the first, second, and third places in the Vietnamese final leg of the contest on Saturday last week, respectively.
Eventually, Garyy Lee, comprising students from Dinh Thien Ly High School in District 7, Ho Chi Minh City, won the first prize for their research into making soundproofing materials from agricultural waste such as coconut fiber, bagasse, and peanut shells.
Their research result showed that materials made from a mixture of coir, bagasse, and peanut shells have better sound absorption than styrofoam.
In the research, sound insulation varied depending on sound intensity and the mixture with a 3-to-7 ratio produced the best soundproofing effect.
Peach and Psss, with members from the same high school as Garyy Lee, claimed the second prize while the third prize went to the Malaysian team Snailians.
