London's massive fatberg to be turned into renewable energy

Britain's biggest fatberg weighing a whopping 130-tonnes is to be transformed into eco-friendly fuel.

The 250 metre-long congealed mass of fat, oil, gress wet wipes and nappies has been slowly been plugging Victorian sewers for years.

The fatberg, which is more than twice the length of two football pitches, took an eight-strong crew using high-powered jet hoses to break up and dislodge the mass.

The team has now transferred the fatberg to a specialist plant where it will be processed with other fats and greases and transformed into a biodiesel.

But unflushable elements including baby wipes, condoms and sanitary products, in the ugly mass found beneath the streets of Whitechapel, east London, will be disposed of.

It may be a monster, but the Whitechapel fatberg deserves a second chance. We've therefore teamed up with leading waste to power firm Argent Energy to transform what was once an evil, gut-wrenching, rancid blob into pure green fuel. It's the perfect solution for the environment and our customers as we work towards our target to self-generate 33 per cent of the electricity we use from renewable sources by 2020. It also means the Whitechapel fatberg will get a new lease of life as renewable, biodegradable fuel powering an engine instead of causing the misery of sewer flooding.
