Revealed: Main culprits that made up monster fatberg
Cooking fats and hygiene products played a pivotal role in the formation of the giant fatberg found lurking under a seaside town, scientists say.
The 64-metre monster – greater in length than the 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.
The fatberg was taken to a local sewage treatment works where it was fed into the anaerobic digester and produced energy to power the plant.
The university team found that the samples they received were mostly made of animal fats – consistent with domestic food preparation – combined with household hygiene products such as wet wipes and sanitary products, as well as natural and artificial fibres from toilet tissues and laundry.
