Sustainability Award for Revolutionary Fog Recovery Technology
In a significant achievement for sustainable innovation, Eco Clarity has been recognised by the prestigious Sassda & Columbus Stainless Awards for technology that revolutionises the recovery of fats, oils and grease (FOG) from food service establishments (FSEs). This innovative solution not only addresses a critical environmental challenge but also contributes to the circular economy by converting waste into a valuable resource: biodiesel.
Addressing a critical environmental challenge
FSEs generate substantial volumes of FOG waste, which can lead to severe blockages in sewer systems and wastewater treatment facilities if not properly managed. The blockages often result in costly clean-up operations and environmental hazards. Eco Clarity’s innovative solution, known as FOG Consolidation Hubs, provides an efficient and sustainable method for the disposal of FOG-laden wastewater before it reaches the sewer network.
Eco Clarity Founder Christopher Clemes shares his inspiration for the project. “The idea for this technology came around a decade ago when I was fly-fishing and noticed the impact of surface oil and other contaminants on water quality. This inspired me to find a solution.”
Material optimisation for longevity and efficiency
Eco Clarity’s technology is designed with material optimisation at its core, ensuring maximum lifespan at minimum cost. Careful selection of materials plays a crucial role in achieving this balance. The plant’s high-frequency product contact surfaces (including key components such as skimming tanks, hardware skid, pressure vessels and flexible tubing) are constructed from 304L stainless steel,
which is known for its durability, hygienic properties and low maintenance.
For non-direct contact surfaces (such as cladding, reinforcement and tank mounting), to ensure structural integrity and longevity, the plant uses 3CR12 stainless steel, which is often painted for additional protection. Shipping containers housing the technology are repurposed carbon steel units, which further emphasises Eco Clarity’s commitment to sustainability and material reuse. Over 60% of the plant’s weight comprises stainless steel, which is fully recyclable, contributing to the circular economy.
Energy efficiency and environmental impact
The energy efficiency of Eco Clarity’s system is a standout feature. The technology enables users to screen and separate water from organic solids and FOG before it enters the water system. The cleaned water can be reused or safely returned to the waste stream while dewatered organic solids and FOG are diverted from landfills and converted into renewable energy.
The Eco-Ceptor, a key component of the system, was shortlisted by Isle Utilities at the Global Water Innovation Summit in 2019 as one of the top technologies for halving the cost of wastewater treatment globally. With a throughput capacity of 15 000 litres per hour, the system operates at an impressive energy efficiency of 6,5 kW/ton through advanced power management software.
The environmental benefits of this technology are substantial. By reducing reliance on landfills, minimising road use by FOG haulers and lowering downstream watertreatment costs, Eco Clarity’s system significantly mitigates environmental impact. The compact design of the hubs, which occupy just 10 square metres, makes them suitable for installation close to FSEs and residential areas, further reducing environmental disruption.
Recycling within the circular economy
At the heart of Eco Clarity’s innovation is the concept of recycling as a contribution to the circular economy. FOG recovered by the system is consolidated into a feedstock suitable for biodiesel production. This biodiesel is blended with traditional diesel enabling FSEs, haulers and water
utilities to run vehicles on their waste. This closed-loop system exemplifies the potential for waste to be transformed into a valuable resource, reducing reliance on fossil fuels and promoting sustainability.
The use of repurposed materials in the construction of the hubs further underscores Eco Clarity’s commitment to recycling. The shipping containers, once their initial purpose is fulfilled, can be repurposed again or recycled as part of the stainless steel production process, reinforcing the company’s
dedication to a sustainable life cycle for all materials.
Overcoming challenges through collaboration
The lengthy environmental permitting process was among the challenges on the journey to success for Eco Clarity. Clemes emphasises the need for modernisation in this area. “We want to provide FOG recovery across multiple locations before grease builds up in sewers but delays in obtaining permits are a major hurdle.”
To overcome this challenge, Eco Clarity is actively engaging with key stakeholders to streamline the permit application process. Collaboration within the water sector is also crucial for scaling up the FOG-to-fuel solution. By fostering partnerships and addressing permitting challenges, Eco Clarity aims to promote a more sustainable and efficient wastewater management system for the future.
