Residents had to attach special Make me a winner address tags to their green recycling bags and were automatically entered into a grand prize draw to get their council tax paid for the year.
The recycling incentive scheme was launched in August 2007 and has attracted more than 40,000 entries. In the year prior to the launch, Swansea Council recycled 428 tones of steel packaging whereas in the last year when the competition was running this increased to 530 tonnes.
Corus steel packaging recycling communications manager Naomi Pope said: Corus is the largest steel recycler in the UK. We are working hard to increase awareness of the benefits of recycling steel packaging and the number of steel cans recycled has more than doubled over the last seven years. This initiative has encouraged even more households in Swansea to join in recycling by putting everything from food and drinks cans to caps and lids from food and drink containers in their green bags.
The steel recycler is aiming to continue with the scheme next year to boost recycling rates further.
John and Barbara Roach from Kittle, Swansea, won the grand prize of a council tax free year.
Their winning tag was selected at random from more than 40,000 entries by The Lord Mayor of Swansea, Gareth Sullivan.
