In '95 as my first fulltime paid job I worked in the summer for about 15 weeks plucking cardboard out of the industrial waste that was brought through, There were 4 of us and we had to pick 4 tonnes a day. At the time, the company (UK Waste), took it to a yard and were paid £85 a tonnes for it. I wish I still knew all the people there to get contacts on where to sell everything for the best prices. I don't know whether its gone up or down in price now but 4 tonnes was a lot of cardboard. Would fill more than one of the big lorry type skips 3 metres high and around 3 width to about 5 metres length and that was when it was crushed down.
