A controversial wheelie bin trial in Hounslow has helped boost recycling rates, council figures suggest.
Wheelie bins were last July issued to 7,300 homes in selected neighbourhoods across the borough at a cost of £153,000 for a six-month trial.
A council survey, published this week, shows overall recycling in those areas increased from 37.1 per cent in June to 40.6 per cent in December.
The amount of waste per household going to landfill from the trial wards, meanwhile, was 76kg a year - or 14 per cent - below the borough average.
The scheme has also been credited with reducing rubbish spilling onto the streets when bags split open.
The trial was intially unpopular in some areas, particularly in Chiswick where some residents argued the bins would make their streets look untidy.
But a council survey suggests 93 per cent of participants were in favour of the new bins at the end of the trial, compared with 80 per cent before it began.
Deputy council leader Colin Ellar said: "These results are encouraging and I am particularly pleased in the way the bins have helped make the streets cleaner.
"The increase in recycling rate is also good news for council tax payers as it helps the council reduce the amount of landfill tax it has to pay."
According to Mr Ellar, the the wheeled bins would pay for themselves in 15 months by reducing the amount of waste being sent to landfill.
However, although they will remain in place in the trial areas, he said there were as yet no plans to roll them out borough-wide.
