FOG-fired fuels
gain momentum The energy potential of FOG waste from homes, restaurants and sewers is well known, and technologies and projects that capture and reuse this valuable resource are now coming into play.
The energy potential of fats, oils and grease (FOG) recovered from wastewater is increasingly being recognised. Collected and processed effectively, FOG is an energy and carbon rich resource and an ideal feedstock to produce energy, fuel and a range of possible biochemical products.
EcoClarity, a London-based company with a manufacturing facility in South Africa, has developed a revolutionary technology for the recovery of FOG generated by food service establishments (FSEs). The patented separation system uses one-fifth of the energy of traditional techniques to harvest a 95% FOG concentrate from wastewater in a continuous process.
The cleaned water is made readily available for reuse or discharge, without requiring storage, while the collected FOG can be used in fuel and energy generation. EcoClarity is establishing a network of FOG ‘recovery hubs’ in the UK, providing suitable locations for hauliers to sustainably dispose

of wastewater containing FOG, preventing it from entering the sewerage network or wastewater treatment works.
EcoClarity recently partnered with Argent Energy at its site in Ellesmere Port, installing a combined recovery hub and separation plant that can process 150 tonnes/day of FOG containing wastewater. The company is offering biodiesel on a wholesale basis to company fleets.
A similar size plant will be shipped to a wastewater treatment works in Hull, in a partnership with Yorkshire Water. Southern Water is also working with EcoClarity and anticipates using the fat which could clog the utilities’ sewerage networks to power vehicles instead.
Fuelling sustainability
FOG from participating food outlets in the city of Brighton and Hove will be delivered to a recovery hub at Southern Water’s treatment works in Peacehaven, where it will be mixed with FOG extracted from the wastewater treatment process and turned into a biofuel. The company is targeting restaurants that already collect FOG in grease recovery units, or fat traps.
Steve Williams, Southern Water’s network protection manager said, “Getting usable oil out of the 51 million litres of wastewater that pours into Peacehaven every day, along with
