What should you do with your old Yellow Pages directory? Take it to school.
Pupils from 300 schools across Northern Ireland want people to bring in their old directories for recycling, earning the school cash prizes and funds to plant hundreds of native trees.
The children are taking part in the Yellow Woods Challenge, a fun environmental campaign run by Yellow Pages, the Woodland Trust and 18 councils across Northern Ireland.
Over the next six weeks, the pupils will be asking people to hand them their old Yellow Pages directories or directory covers when the new directory is delivered.
Yellow Pages will award schools that recycle the most directories per pupil with a share of £13,300 in cash prizes and a special 'Seeds to Trees' pack.
Richard Duggleby, head of external relations at Yell, which publishes the directories, said: "The Yellow Woods Challenge is a simple and fun way of engaging schoolchildren and local residents in a worthwhile environmental activity.
"At the end of the competition, the old Yellow Pages directories will be recycled into egg boxes and cardboard by Huhtamaki in Lurgan."
The pupils will also be asked to enter the Big Yellow Pages Art Competition, where cash prizes of up to £1,000 are awarded to schools which build the best Yellow Pages artwork in the UK.
For every pound Yellow Pages awards to schools, a matching pound goes to the Woodland Trust. The money will be used to support the charity's 'Tree for All' campaign - the most ambitious children's tree-planting project ever launched in the UK, which aims to plant 12m trees by 2009.
Janice Hix, corporate partnerships manager at the Woodland Trust, said: " What's great about the Challenge is that children experience first-hand how they can help the environment. Getting kids excited about trees, together with the animals and creepy-crawlies that woodland supports, is so important if we are to ensure our green spaces are protected now so that everyone can enjoy them in the future."
Free curriculum-linked resources are given to every participating school.
Kirk, the campaign mascot, features on all the activities and helps educate pupils about the importance of recycling, woodland conservation and caring for the environment.
Since the Yellow Woods Challenge began in September 2002, participating schools across the UK have helped recycle 1.8m old Yellow Pages directories and helped raise £290,000 for the Woodland Trust.
