Household cooking fats and hygiene products played a pivotal role in the formation of the giant fatberg found lurking under a seaside town, scientists have revealed. The 64-metre monster - greater in length than the Leaning Tower of Pisa - was discovered under The Esplanade in Sidmouth, Devon, just before Christmas last year. A team of scientists from the University of Exeter were asked to carry out an extensive 'autopsy' of the fatberg to try to solve the mystery of how it was constructed and whether it posed any environmental risks. The scientists were given four samples from the fatberg, each weighing around 10kg, after South West Water workers spent eight weeks removing it from the sewer. In total, 36 tanker loads - each 3,000 gallons - of debris were excavated and removed by a dedicated team of seven specialists.
