Finding out about plastics

We have been researching different types of plastics to see which ones we can recycle at school.  We looked at all the different products that are made from plastics with codes between 1 and 7.  Most of our common produucts like drink bottles and milk bottles are made from code 1 and 2 plastics.  We know that glad wrap and plastic bags are not to be put in the recycle because they cause problems with the equipment at the recycle centre.  We presented all our information at a school assembly.
