Lewis School Pengam took part in a YRE introduction session for teachers and students and then a community litter pick along a local river walkway.. The students were very enthusiastic and the highlight was finding a Pepsi Cola can from the 1980's. Much fun was had guessing how old it could be and it was a fantastic demonstration of how long it takes for drink cans to biodegrade in the environment. The story  of the ancient can was picked up by the local press 'The Caerphilly Observer'.
