Students join green force
From now until June, students will tend gardens and grow vegetables at the Hong Kong International Airport in Tung Chung.
The organic gardening competition, a pilot scheme under the airport waste recycling programme, is jointly organised by the Airport Authority (AA) and the Environmental Protection Department.
The aim of the competition is to get schools close to the airport to take part in the AA's waste reduction projects.
Fertilisers will come from restaurants at the passenger terminal. Kitchen waste will be collected and a special waste eliminator will turn part of it into water with nutrients for plants.
Two compost units will also turn the waste into chemical-free solid fertilisers.
Each unit can compost 100 kilograms of food waste a day, taking 108 tonnes of waste off the landfills a year.
At present, part of the airport landscape is irrigated with treated waste water from the passenger terminal.
Students will be growing lettuce and other vegetables at their schools and at the airport along the East Coast Road, with mint and marigold providing a natural pest control.
Their produce will be judged according to height, weight and size.
The competition is sponsored by Yee Sun Garden Limited, with technical support from the Produce Green Foundation.
