Three fourth-grade students from Dang Chau Primary School in Tuyen Quang designed a steel boat with an oil spill-absorption and -filter system after they had been taught about the influence of oil spills on the environment.

They used bagasse for the filtration.

They also made a model of a solar-powered water treatment tank.

Two high-school students from Van Ban High School in Lao Cai province made an instrument that measures water level and speed, automatically lights up at night, catches hazardous insects and warns of danger in spillways.

They hope to popularise the instrument in northern provinces to ensure safety for teachers and students during the rain-flood season.

Twenty-eight other teams won excellence awards.

The contest was meant for students aged 6 to 30.

Nearly 1,500 entries had been received by the Vietnam Environment Administration, which organised the contest together with the Ho Chi Minh Communist Youth Union’s Central Committee. Friesland Campina Vietnam was the main sponsor.

The entries pertained to energy saving, environment-friendly products, biological conservation, and solid, liquid and gaseous waste recycling and treatment.

Some also suggested policy and education solutions for environment protection and IT application in environment management.

The contest was part of a programme called For Vietnam’s Green Environment carried out by the administration and the company since last year.
