One industry's waste is another industry's raw material. These one tonne bales of scrap card are the by-product of cardboard box manufacturing. A single cardboard box production line may produce up to 4,000 boxes per hour. And while waste has been reduced to a minimum, offcuts are inevitable.

This may be waste material from one factory, but these bales of card are the raw material for another – paper pulp production. The card is shredded, pulped and moulded. At the end of its useful life the moulded pulp can be recycled once again, or composted (it's fully biodegradable).
