Dubai's Aviation Giant Turns Food Waste to Water with New Tech

DUBAI, UAE – February 06, 2026 – In a landmark move for industrial-scale sustainability, Emirates Flight Catering (EKFC), one of the world's largest airline catering operations, has activated a high-capacity automated system at Dubai International Airport (DXB) that liquefies tonnes of daily food waste, effectively diverting it from landfills. The installation, engineered by California-based Power Knot LLC, marks a significant step in the aviation industry's efforts to tackle its environmental footprint.

Serving over 320,000 meals daily, EKFC's operations generate a substantial volume of organic waste. The newly commissioned Power Knot Automated Feed System (AFS) is designed to process this waste at its source, converting it into environmentally safe grey water that can be discharged directly into the sewage system.

A Technological Leap in Waste Management

At the heart of the new installation is a sophisticated, synchronized chain of machinery designed for seamless, automated operation. The process begins with the SBT-140 bin tipper, a battery-operated unit that safely lifts and empties bins of organic waste into a heavy-duty BCG-315 grinder. This grinder is engineered to handle even tough materials like bones and fibrous food scraps, breaking them down into a consistent particle size.

From the grinder, an FSC-500 screw conveyor transports the macerated waste across a 5-meter span directly into the flagship LFC-2000 biodigester. This central unit is a powerhouse of green technology. Using a process of aerobic digestion, a proprietary mix of microorganisms, oxygen, and heat breaks down the organic material completely, typically within 24 hours. The biodigester is currently processing over three tonnes (3,000 kg) of food waste daily, with its capacity expected to ramp up to six tonnes (6,000 kg) per day as the microbial colony matures.

This integrated system not only automates a labor-intensive process but also provides valuable data. Power Knot's LFC biodigesters are connected to the LFC Cloud, a remote monitoring platform. This allows EKFC to track usage statistics, monitor system diagnostics, and generate reports on the amount of CO2 equivalent emissions diverted from landfills, providing quantifiable metrics for its sustainability efforts.

The Environmental Imperative

The environmental benefits of this onsite solution are profound. When food waste is sent to a landfill, it decomposes anaerobically, releasing methane—a potent greenhouse gas with a warming potential more than 25 times that of carbon dioxide. By diverting this waste, EKFC is directly combating climate change.

Based on industry data, diverting a single tonne of food waste from landfill prevents approximately 0.7 tonnes of CO2 equivalent (CO2e) emissions. Once the biodigester at EKFC reaches its full operational capacity of six tonnes per day, it is projected to prevent the emission of over 2,000 tonnes of CO2e annually. This is a significant reduction that also eliminates the carbon footprint associated with trucks transporting the waste to distant landfill sites. Beyond the carbon savings, the system mitigates odors, reduces pests, and lowers waste disposal costs, creating a cleaner and more efficient operational environment.

Part of a Broader Green Strategy

For Emirates Flight Catering, the adoption of this large-scale biodigester is not an isolated initiative but a cornerstone of a comprehensive and ambitious sustainability strategy. The company has been methodically integrating environmental considerations into every facet of its operations, viewing responsible waste handling as both a commercial and ecological imperative.

This major installation was preceded by a successful pilot with a smaller Power Knot LFC-50 biodigester in 2025, which validated the technology and paved the way for this larger investment. The company's commitment extends far beyond waste. In the past year, EKFC installed a vast solar panel array that generated 4,000 MWh of green energy, and it is a key partner in Bustanica, one of the world's largest vertical farms, which produces pesticide-free leafy greens using 99% less water than traditional agriculture.

In his statement, Shahreyar Nawabi, Chief Executive Officer of Emirates Flight Catering, highlighted the project's importance. "At EKFC, when we look at where we can make the greatest difference, it's in how we handle waste by treating it responsibly, diverting it from landfill, and finding ways to put it back into productive use," he said. "Commissioning a biodigester of this scale is a major operational milestone for us as we accelerate EKFC's landfill diversion efforts."

Nawabi also credited the project's success to internal collaboration and the dedication of ground teams in segregating waste, emphasizing that the combination of innovative technology and operational commitment is key to their ongoing sustainability progress.

A Scalable Model for Global Industries

The successful implementation at a facility of EKFC's scale and prominence serves as a powerful case study for numerous other industries. The challenge of managing high volumes of organic waste is not unique to airline catering. Hotels, cruise lines, large corporate and university campuses, hospitals, and convention centers all face similar issues.

Power Knot's modular and scalable technology offers a replicable blueprint. The ability to process waste onsite provides a compelling economic and environmental argument, particularly as global regulations around landfilling organic waste become stricter and corporate social responsibility targets grow more ambitious. The shift toward a circular economy, where waste is viewed as a resource to be managed rather than discarded, is driving demand for solutions like aerobic biodigesters.

By demonstrating the viability of this technology at one of the busiest airports in the world, Emirates Flight Catering and Power Knot are not just solving a local problem; they are showcasing a sustainable path forward for high-volume industries globally, proving that operational excellence and environmental stewardship can go hand in hand.
