Toilet Roll

S4, E2: Gregg Wallace explores the Manchester factory that produces 700,000 toilet rolls a day. He begins 940 miles away in Sweden where the raw material, wood, is harvested from a sustainable forest of one billion spruce trees. Most of the wood is used for timber, but the off cuts are turned into sheets of wood pulp. Gregg follows this pulp to Manchester where he learns that two types of wood fibre, long and short, are required for loo roll, to give it strength but also softness.
