We don’t stop to think about what happens to the leftover cooking fat we tip
down our kitchen sinks. But when it gets into the sewerage system it can
create enormous blockages called ‘fatbergs’. They have become so common
that a definition has been added to the Oxford English Dictionary.
Fatberg: ‘A very large mass of solid waste in a sewerage system, consisting
especially of congealed fat and personal hygiene products that have been
flushed down toilets’.
Argent Energy made the news when it volunteered to turn the largest fatberg
ever found, into biofuel. A 250-metre long monster weighing 130 tonnes had
to be dug out of an east London sewer in September 2017. Some of it was
taken to Argent Energy
