P for Plastics


I can hold my head up here - I have actually written to my local paper about plastics and recycling them. Plastics are a major offender in the packaging of items from foodstuffs to postal cushioning. A lot of packaging materials are made from polyethylene (PE) and polypropylene (PP). These are biodegradable, but require a lot of time and special conditions to degrade and are not considered viable to recycle – certainly in the UK which still does not have household collection of plastics everywhere.
It is hard to find out about if the plastics we put in our recycling bins are actually recycled. We tend to go by the numbers on the base. The symbols here – polymer ID or PET codes - were actually developed by the American plastics industry to give the plastic recycling industry a rough guide to the many different plastic polymers in use today. But the symbols do not necessarily mean that a plastic can be recycled and they often cause confusion. It does seem, in the UK at least,  that those with code 1 and 2 are recycled if they are bottles but beyond that who can say?

I am using the word "recycle" but plastics don't actually get reformed back into the original products but are reprocessed into secondary (and usually non-recyclable) products. 

There are packaging companies all around the world trying to come up with solutions to replace the PE and PP granules with natural materials like starch, corn, wood pulp and cotton, potato, sugar-beet, soy, tobacco, sugar cane, cellulose and lignite. Read more on eHow and Which.

  1. At least we can now put certain plastic items in our recycling bag. I thought they were developing ways of recycling plastic more efficiently now. *sigh* Our future will be a land where the whole of the ground is covered with old plastic carrier bags!

    1. Almost there with a recycling bag - still have to trundle an enormous bag to a car park recycling area here...bet a lot of people don't bother.

  2. Thanks for visiting my blog earlier, and for the follow - following in return!

    Plastic annoys me - especially the packaging around toys. At least Easter eggs are less likely to come in plastic - Cadbury's seem to be leading the way on that one.

    1. I noticed that with my easter egg - they made a thing about the card insert instead. Good move! Thanks for coming over..

  4. I think we are lucky where we live, the council seem to take the majority of plastic items for recycling. Although I'm not sure what they do with them...I hope they get turned into something useful!

    Found you on the AtoZ Challenge, hope you are enjoying it so far!
