A "rag bag" army of pupils at Cardross Primary School have celebrated another victory in their battle to save the planet.

The school's young eco warriors dispensed of their usual smart clothes on Friday and donned a weird range of outfits made from rubbish and recyclables.

The "trashion" show was to mark the official hoisting of their third green flag - awarded to the school for their continuing work to promote the best of all things 'green'.

And while the outlandish styles were all just for a laugh, there was a serious message behind the escapade, with recycling being a key element.

Head teacher Elspeth Davis told the Advertiser that this third flag marked the success of the school in continuing to meet criteria set down by Eco Schools Scotland which encourages young people to engage in their environment by allowing them the opportunity to actively protect it.

Elspeth said: "We are very proud to receive our third green flag. The whole school has a worked very hard to achieve it."

Pupils watched on proudly as the flag was raised by Councillor Ellen Morton.

The councillor said: "It was an honour to raise the flag as this - their third - is a significant achievement for the school, and the pupils and teachers deserve full congratulations.

"It was a very entertaining day, with the children dressed imaginatively. The message was 'there is no such thing as waste' - it all can be recycled. It was a great laugh as well as being educational."

Pupils, led by principal teacher Kelly Girling and the school's eco committee, are involved in a whole range of activities to boost the school's green credentials.

The children are encouraged to come to school by walking or on scooters or cycles - with special parking areas provided.

Plums and apples grown in their orchard are used in the school kitchen and the primary six "waste team" keeps a close check on the amount of food waste by weighing the amount discarded every day and compiling weekly statistics.

The school is run in an energy efficient manner, with the heating turned off when it's not needed, and recycling is routinely carried out.

Pupils also enjoy outdoor learning in local woods and along the shore, with several teachers being trained in woodland leadership.

The school also has a very ambitious textile recycling project which raises funds which are ploughed back into the eco work.

Elspeth said: "We have a textile bank in the playground for the public to use and the pupils have a twice-yearly collection of unwanted textiles around the village. We earn money through a recycling company which comes and weighs the collected textiles and last year we raised £518.

This money, plus what we expect to receive from the Tesco Bags of Help scheme, will be used to buy a polytunnel to grow vegetables and fruit.

"Our first green flag was awarded six years ago, so this is a very well embedded theme, and not just lip service. The school has worked very hard to achieve its green flags."
