Recycling and Rainham MRF

Keeping recyclables separate, or separating them out when they've become mixed ("comingled") is something I've pondered. The Barking & Dagenham Post (26 Sep) carried an article about Rainham Materials Recycling Facility (owned by Veolia). All kinds of clever gadgets sort the waste out automatically into:

Quality paper
Mixed paper
Polyethylene terephthalate (PET) - eg soft drink bottles
High-density polyethylene (HDPE) - eg milk polybottles
Mixed jazz *
cardboard
plastic film (eg thin carrier bags)
aluminium
steel

The Post says "7 grades of waste are baled separately" but I make it 9.

It seems sensible that all these materials can go in our orange bags, and also that they should be kept separate "up stream" where possible - by use of bring banks. * - The Post article gives the example 'coloured bottles' for 'mixed jazz' but according to http://www.plasticsrecycling.co.uk/ it seems to be some kind of plastic recyclable material.

I think the plant can process black bag general waste, too. Presumably separately from the orange bag stuff.
