There is revolution going on in waste management, which Big Brother would be proud of.

Tucked away under the rim of wheelie bins found in two Sydney councils are small radio frequency tracking devices collecting information on a household's waste habits.

Randwick Mayor Bruce Notley-Smith told The World Today they are the way of the future.

"We will be able to find out the weights of the various bins and collect the data, the entire amount, as opposed to the quantity that is recyclable," he said.

The garbage truck reads the data on the bin, weighs the bin, and the data is collated on a computer.

"We've aimed to increase or target problem areas in the city where there's a lower level of recycling," Mr Notley-Smith said.

"The fact is that 50 per cent of the city of Randwick is multi-unit dwellings and we have faced a number of challenges there with getting compliance with recycling."

The data collected will allow the council to confirm which areas are recycling and which are not.
