Turning fatbergs in to biodiesel

Turning fatbergs in to biodiesel

Fatberg, the alternative oil source you may not know about. People pour fat and grease down their kitchen sinks and drains, this then causes the drains to block. Here at Metro Rod Dorset we specialise in unblocking your drains and properly disposing of the material causing the disruptions.

In London congealed lumps of fat, and other nasty things stalk the sewers, causing blockages and damage to water infrastructure.  Thames Water is working on an innovative solution to fight these fatbergs by turning them into biodiesel.

The water utility has joined forces with renewables firm Argent to investigate the feasibility of turning the fatbergs into renewable biofuel. The plans would see fatbergs dug out of the sewers and transferred to a specialist plant where the fat, diesel and greases could be turned into biodiesel. Other unflushable items such as baby wipes would have to be disposed of.

Thames Water has been working hard in recent months in an attempt to solve the fatberg problem, launching a wide ranging awareness campaign dubbed “Bin it don’t block it”, encouraging Londoners to do their bit to avoid sewer blockages

The biodiesel scheme has been described as a “no-brainer” by Simon Brum, strategic recycling manager at Thames Water. “We have a problem with fatbergs, both in sewer networks and at sewage treatment centres. Previously, what we’ve done is either extract the fatberg out of the pipes and send to landfill, or break it down and put it back through the system. Now we’re looking to see if we can use fatbergs in a clever way, and we’re working alongside Argent to do that," Brum said in a statement from Thames Water.

“Let’s be clever, remove them, and then do something good for the environment.”

It is hoped that the biodiesel produced could eventually be used to power buses in the Thames Water area.
