Eco Clarity’s fat-to-fuel technology is helping to keep the region clean by stopping fatbergs forming in our sewers and creating an environmentally friendly biodiesel instead.

According to The Flood Hub, every year in the north-west, there are 28,000 avoidable sewer blockages – largely due to the incorrect flushing of unsuitable objects like wet wipes and the incorrect disposal of fat, oil and grease (known as FOG) down kitchen sinks.

The build-up of these items results in a rock-hard blockage, that continues to grow, sometimes known as a fatberg.

Andy Peet, Wastewater Network Protection Manager for United Utilities said: “FOG buildup in the drains is an ongoing issue for the business. Along with rag and wipes, these blocked drains cost United Utilities over £3.5m a year to sort out.

United Utilities have also installed orange bins across its headquarters site in Warrington for staff to bring in and recycle FOG from their homes, doing their bit to help the environment and keep it out of the drains. Around 360 litres of FOG have been collected so far for recycling into biodiesel.

“One of our large tankers (also known as Water on Wheels) does, on average, eight miles per gallon or 1.76 miles per litre – so we’d be able to travel around 630 miles – enough to just about get us to from our Lingley Mere site to Balmoral Castle and back.

“Staff at United Utilities are doing their bit for a greener future, and we hope that over time we’ll be able to build on the success of this project and continue working with Eco Clarity to repurpose FOG into biofuel.”

Eco Clarity’s North West FOG Recovery Hub

Eco Clarity, an award-winning green technology company, has recently opened a new recovery hub in Stockport, processing FOG from across north-west England.

“This innovative partnership demonstrates how collaboration between businesses and utilities can effectively address environmental challenges across the region. We are the only facility in the north-west focused on converting FOG waste into renewable biodiesel,” explained Laura Su, Eco Clarity’s business development manager.

“Eco Clarity’s technology takes a waste product and transforms it into something useful, reducing the risk of fatbergs and sewage pollution.”

Eco Clarity works with restaurants and food businesses across the region to dispose of their fat, oil and grease waste responsibly. The company’s chemical-free system separates out clean water, so it can be reused or safely returned to nature, and the leftover FOG waste is sent to its partner to be turned into clean energy instead of blocking sewers or being dumped in landfills.

Argent Energy – Where FOG feedstock is transformed into sustainable biodiesal

Argent Energy, based in Ellesmere Port, converts the recovered FOG into valuable waste-based biodiesel, a renewable alternative to fossil fuel diesel that helps reduce CO₂ emissions

“Working alongside Eco Clarity allows us to play a crucial role in closing the loop on FOG waste in the north west by turning problematic waste into a valuable renewable fuel,” said Jan Jaap Rodenburg, Head of Commercial at Argent Energy. “This partnership highlights the power of collaboration, and we’re excited to be part of a solution that benefits the environment, communities, and the regional economy.”

The north of England is increasingly recognised as a powerhouse in innovation, sustainability and economic growth, and this regional collaboration showcases the power of local innovation.
