Measuring and repurposing FOG waste

by Eco Clarity | Mar 11, 2025

For too long, businesses have had limited visibility over what happens to their fat, oil and grease (FOG) waste once it leaves their site.

Traditional waste disposal routes often provide little to no data, making it difficult to track volumes, understand impact, or report on sustainability performance.

At Eco Clarity, we are changing that.

Our real-time, cloud-based tracking system provides businesses with full transparency on every load collected, offering:

Precise measurement of total waste and FOG
Detailed breakdown of waste composition
Traceable data for compliance and sustainability reporting

This level of traceability is unmatched in the industry. Businesses no longer have to guess where their waste is going or how it is being processed. Instead, they gain full oversight and control over their waste stream, ensuring compliance, operational efficiency and clear environmental reporting.

Beyond waste: Turning FOG into a valued resource

FOG waste has long been seen as a disposal challenge but holds significant untapped value. When properly collected and processed, it becomes a high-quality feedstock for biofuel production, reducing reliance on fossil fuels and contributing directly to the UK’s net-zero targets.

Through our process:

Every drop of FOG waste is measured, valued and repurposed into a useful resource rather than being simply disposed of.
Businesses can quantify and report their carbon savings, supporting their ESG and Scope 3 emissions targets.
Waste that would otherwise enter mixed waste streams or even anaerobic digestion (AD) is given greater value, improving its calorific content and impact.
Support a new, sustainable market for FOG waste, transforming homegrown waste into a feedstock that directly supports the UK’s renewable energy transition and 2030 net-zero goals.

A smarter, more accountable approach to waste management

By providing businesses with real-time data and complete transparency, we enable them to make informed, strategic decisions about their waste. No other known provider offers this level of insight into FOG waste disposal.

The result? A fully traceable, efficient, and high-value waste management solution that recovers even the smallest waste value and transforms it into something greater.

At Eco Clarity, we believe FOG should be a resource rather than an afterthought.

How North West companies unite to save sewers

by Eco Clarity | Feb 19, 2025

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.
