Inside the Factory: Toilet Roll (Toilet Tissue) (Tissue Paper)

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 offcuts 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 a loo roll, to give it strength but also softness. He watches as 3,750 kilos of fibre are combined with 34,000 litres of water and sprayed into a 40-metre-long, 11-metre-high paper-making machine. It takes just four seconds for the watery pulp mix to be transformed into soft, dry paper. It is then rolled onto a 1.2 tonne supersized toilet roll known as a 'mother reel'. Each one of these gives birth to 25,000 individual toilet rolls. Meanwhile, Cherry Healey is at Britain's oldest toilet factory, where they churn out 1,000 loos a day. And she gets the bum deal of following the flush through the sewers and water treatment works of Brighton, finding out how sewage is cleared of debris, grease and bacteria, and transformed into clean water in a little over an hour after flushing. She has a cheeky encounter with a high-tech Japanese toilet and heads to Cranfield University to see a prototype toilet that does away with the need for water altogether. Could this be the toilet of the future that gives one-third of the world's population access to efficient sanitation?
