Water butts, composters, recycling bins and even rap music are among the weapons in the battle to become Abingdon's greenest school tomorrow.

Six schools in the town are competing in the fourth annual sustainability awards, which are organised and sponsored by Abingdon Business Park, in association with Abingdon in Bloom. Children of all ages have taken up the challenge.

Business park manager Chris Neal said: "The entries include a lifesize model made from recycled items. We have had projects on saving water, composting, recycling, and a walk to school week. One school did a rap, which they are using in their assembly and a small play based on water saving."

Last year, the winners were presented with a bench made from wood from sustainable forests. This year's winning school - to be announced at the Management Centre, in Abingdon Business Park - will receive a voucher. Schools taking part are St Edmund's Primary School, Thomas Reade Primary School, Caldecott Primary School, Dunmore Infants School, Larkmead Secondary School and the Abbey Centre for adult education.

Each age group at Thomas Reade Primary School took part, with the foundation stage making junk models, Key Stage One doing a project on reducing waste, and Key Stage Two pupils raising enough money to install a water butt. Headteacher John Serle, pictured with some of the pupils, said: "It's massively important that they are aware of these issues because it is our future."
