I worked for a waste management company called Veolia - although they are expensive to dispose of, I did find out quite a few things. Certain tips will recycle it for you, possibly for a small fee too - but if they wont accept it, you may need to get a private company to dispose of it. Like Biffa, or Veolia...the number to get it disposed of at Veolia is 0151 348 5000, and ask for Matthew Smith, he will produce a quote for you, you have no obligation to accept the quote though, you can take it yourself to a site, and you will only pay for disposal. Dont know whether that helps.
Life isnt a practise,you have to get it right first time!
