MAIN FEATURE
easy decision once we looked at the holistic benefits of Eco Clarity’s hubs,” says Gudgeon. “It brings us another avenue of engagement with the food industry and the FSEs [food service establishments] out there; it reduces the amount of FOG going into sewers at source – preventing sewer blockages and protecting the environment, ultimately resulting in protecting our people not having to do high risk jobs.
“It also enables us to bring in new waste streams and new revenue streams into Yorkshire Water and ultimately that money is reinvested into the business and goes towards helping keep customer bills low - it is a true circular economy in action,” he adds.
FOG is a common byproduct of commercial kitchens and food processing facilities, but its disposal has long posed a challenge to the water sector. Eco Clarity’s work with waste service contractor Serious Waste Management exemplifies the power of partnerships in unlocking a FOG-to-fuel circular economy.
“Grease trap waste can be recycled into biodiesel,” explains Rob
Menzies, managing director, Serious Waste Management.
“Collaborating on FOG recovery and reuse is a win-win situation for businesses, hauliers, the water sector and the environment. It promotes resource recovery, reduces landfill waste, creates a closed- loop system, and contributes to a more sustainable wastewater management system.”
The patented Eco Clarity system efficiently separates fat, oils and grease from wastewater, resulting in a 98% concentration of oil suitable for biodiesel production, which could ultimately be used to power the trucks transporting the FOG. Using Eco Clarity, Serious Waste Management has saved nearly 50,000 tonnes of GHG emissions since the company began working together just over two years ago.
As Eco Clarity sites are registered with Argent Energy's Carbon Certification Scheme, the company can track the volume of greenhouse gas (GHG) emissions saved by the biodiesel produced from its FOG feedstock. This allows third-party companies, disposing of their waste in this way, to demonstrate their commitment to sustainability with transparency.
Long travel distances, slow offloading times, limited data on waste content, and a lack of transparency in pricing have historically led to frustration and a drain on profits for liquid waste operators. Thanks to Eco Clarity’s highly efficient disposal opportunities, first at Argent Energy’s refinery in Stanlow, Cheshire, and now at Hull wastewater treatment works, travel distances for hauliers are minimised, along with fuel consumption.
Eco Clarity’s FOG Recovery Hubs analyse the precise mass and FOG content of every load that comes in. As the FOG-rich waste goes through a mass meter, it is quantified and the data shared with the client - supporting their green credentials.
This also translates to quicker turnarounds for tankers, lower operating costs, and more time spent serving customers. Boasting up to a 87% reduction in greenhouse gases, biodiesel contributes to climate change mitigation and could be used to power tankers
