Over the next fortnight, the UK will create around 30 per cent more waste than usual, including six million Christmas trees and 225,000 miles of wrapping paper. For merry-makers, the festive season is fun, tiring, indulgent and, at times, excessive. For retailers, it is invariably the most important period in the year. And for Biffa, it is exceptionally busy. Biffa picks up refuse from 2.4million households and 72,000 businesses, including major chains such as John Lewis and Sainsbury’s.
