A FURTHER 1 million households will be added to the city's "green account" scheme this year in an effort to boost people's interest in sorting garbage, authorities said yesterday.

Green account holders earn points by dumping dry and wet garbage into different bins. They can redeem the points for milk, cellphone cards and tickets to tourist attractions, or use them to pay their utility bills.

Volunteers work in neighborhoods to help people sort their garbage. They also give out the reward points.
