Recycling codes and the environment

Although plastics have had a remarkable impact globally, it has become increasingly obvious that recycling of all plastic materials is essential.

To assist recycling of disposable items, the Plastic Bottle Institute of the Society of the Plastics Industry devised a now-familiar scheme to mark plastic bottles by plastic type. A recyclable plastic container using this scheme is marked with a triangle of three "chasing arrows", which enclose a number giving the plastic type
