The war against rubbish never stops for the waste men of Newcastle. But the things we throw away have never been worth so much. On the streets of the city no bin, skip or piece of scrap metal is safe from the opportunists who have learned how to turn rubbish into cash. But, as the waste men working at the city's tips know, the value of waste is not simply financial. Often it's the emotional value that means that one man's rubbish really is another's treasure.
