GORSE Hall Primary, Stalybridge, has been honoured by Keep Britain Tidy for being eco-friendly.
It is one of only eight from 19,000 registered schools to be included in their Hall of Fame.
And to mark 21 years as having eco-school status, Gorse Hall held a special environmental science week.
It culminated in a special assembly at which Jonathan Reynolds, MP for Stalybridge and Hyde, attended.
It was described as: Eco 21: celebrating 21 years of making positive and sustainable changes to our environment”.
Francis Hyland, Keep Britain Tidy’s eco-schools’ co-ordinator, spent part of the week at Gorse Hall which has a plastic free playground
“I went out with the children litter picking as part of the Great British Spring Clean and it was clear how embedded environmental education is and how much the children were engaged,” he said.
Children spent one day at Gorse Hall Country Park where they carried out biodiversity workshops.
Leah Troy, an undergraduate at Newcastle University, led a school grounds biodiversity audit entitled: “What’s under your feet”.
Pupils also collected data for the British Trust for Ornithology.
There was also visits from representatives from Viridor Waste, Tameside Council about air pollution, United Utilities’ Kingfisher education programme and a pilot from Ryan Air.
Pauline Ashton, vice chair of governors, can remember the school gaining eco status.
She said: “Maurice Smith, an adviser for environmental health with the local authority, did a lot of work at school.
“It was through his encouragement that we went for the eco schools awards leading to us being awarded their green flag.”
