To give further explanations we have written a couple of blogs about recycling of plastics - https://www.pavilionearth.co.uk/promotional-gifts-and-the-recycling-of-plastics is an overview of all the plastic types and which can and cannot be recycled. The most interesting being how PET is transformed for carbonated drinks bottle into a fine yarn used for clothing. A process described in full here https://www.pavilionearth.co.uk/how-is-polyester-pet-recycled. The issue is a little complicated for some plastics because as well as manufacturing items for virgin polymer many application use a proportion of recycled material. Pavilion identifies those which are 100% recycled polymer – although in truth any amount of recycled polymer is to the benefit of the environment.
