Shanks increases food waste input by 150% at Westcott Park AD Facility

Shanks Waste Management has increased food waste input into its Westcott Park anaerobic digestion (‘AD’) facility in Buckinghamshire by 150% since the summer.

As the facility reaches the end of its commissioning period, it has increased food waste input from around 400 tonnes per week to over 900 tonnes per week, an increase of 150%. As a result of this increase in food waste, the facility is able to boost production of a nutrient-rich digestate and also export 3MWh of green electricity back to the National Grid, enough to power 14,000 homes.

The significant increase in food waste input is a result of a number of modifications and improvements to the original facility, including changes to the pre-pasteurisation buffer tank mixing system. These changes ensure that the facility can support optimum methane generation. Additionally, the facility has recently secured a contractual arrangement with a digestate offtaker to deploy all digestate produced at the facility to the agricultural sector.

Peter Eglinton, Managing Director of Shanks UK Municipal Division, said:

“Organic waste is one of the most environmentally damaging forms of waste to be sent to landfill so I am delighted that our Westcott Park AD facility is continuing to reduce this burden on the environment by increasing the amount of this waste which it is processing. To increase food waste input by 150% in just three months is a great achievement and I look forward to seeing the facility continue to ramp-up over the coming months.”

The facility has the capacity to process 48,000 tonnes of food waste each year at its strategically-placed location between the M40 and M1 motorways. The fundamental design principles for the facility are based on Shanks’ wealth of experience developed at other organic waste facilities in the Netherlands, Belgium and Scotland.
