Emirates Flight Catering has installed a large-scale biodigester at its Dubai facility, aiming to process thousands of tonnes of waste annually and significantly cut carbon emissions, signalling a major advance in airport environmental initiatives.
Emirates Flight Catering has recently installed a large-scale biodigester at its Central Commissary Unit in Dubai, which marks an important step in the company’s efforts to manage organic waste right at the source instead of sending it off to landfills. According to reports from Breaking Travel News and an official statement from the company, the Power Knot LFC‑3000 started operating in December 2025 and is already processing several tonnes of food waste every day.
This biodigester uses an aerobic biological process that depends on heat, oxygen, and microbes to break down organic material. The process produces grey water that’s suitable for non-potable uses, and unlike mechanical systems, it actually becomes more efficient as the microbial culture adapts to a wider variety of waste. EKFC estimates that the system currently handles up to 3.5 tonnes daily, but this could increase to around 6 tonnes once the biology matures fully and feedstock stabilises. The company projects that, once operating at full capacity and biological maturity, the system could prevent more than 2,000 tonnes of CO₂ equivalent emissions annually, based on greenhouse-gas conversion factors aligned with the UK’s Department for Environment, Food & Rural Affairs (DEFRA).
Shahreyar Nawabi, the CEO of Emirates Flight Catering, called the installation a significant operational milestone. He explained: “At EKFC, when we think about where we can make the biggest difference, it’s in handling waste responsibly, treating it properly, keeping it out of landfills, and finding ways to reuse it productively. Setting up such a big biodigester is a major milestone for us as we ramp up our landfill diversion efforts. The success of this project really depended on teamwork across different parts of the business, along with consistent waste segregation efforts by our ground teams. Combining innovation with a focus on operations, that’s what will keep driving our sustainability initiatives forward.”
Industry suppliers point out that automation plays a key role in making such systems work smoothly. Power Knot and related companies have released information about an Automated Feed System that combines bin tipping, grinding, and screw-conveying modules that feed directly into the biodigester. According to a Power Knot statement passed along by PR Newswire, this setup speeds up waste handling and reduces the need for manual loading, letting EKFC divert over three tonnes of food waste every day into on-site treatment. Sustainability outlets like Clean-the-sky also note that these integrated systems are effective in lowering emissions related to transport and logistics, reducing the effort and costs associated with offsite disposal.
The biodigester is just one part of a bigger environmental push at Emirates and EKFC. For example, their own reports reveal that rooftop solar panels produced roughly 4,000 MWh of energy last year, enough to avoid about 1,600 tonnes of CO₂ emissions. The catering arm is also testing electric ground support equipment, with a proof-of-concept electric hi-loader expected around mid-2026. Plus, they have started introducing electric vehicles into parts of their fleet. Emirates Group also details ongoing recycling programs, fuel-efficiency measures, and eco-conscious product choices onboard flights.
Waste reduction strategies go hand-in-hand with the on-site digestion efforts. EKFC notes past success with a smaller biodigester, the LFC‑50, which processed nearly 75,000 kg of food waste last year. They’ve also revamped their inflight logistics by replacing single-use cardboard packaging with reusable crates, something they estimate will save about 750 tonnes of cardboard waste each year. Innovation extends to vertical farming and creative reuse of waste: EKFC says they’ve repurposed kitchen trimmings into 47 menu items and sourced pesticide-free lettuce from vertical growers to supply tens of thousands of salads daily.
From a climate-technology perspective, doing on-site biodigestion helps tackle two major sources of greenhouse gases: methane emissions from decomposing organic waste in landfills, and emissions from transporting waste offsite. Using DEFRA-aligned emission factors, EKFC estimates that diverting one tonne of waste from landfills avoids roughly 0.7 tonnes of CO₂e. When scaled up, this can lead to meaningful reductions, especially for a busy caterer operating within a major airport hub.
That said, experts note that the success of biodigestion hinges on several factors, mainly the quality of feedstock, disciplined operation, and how well outputs like grey water are reused within local regulations. The actual impact on emissions will depend on the waste mix and how disposal was handled previously. Independent verification of the claimed CO₂ savings and detailed operational data will be crucial for confirming the long-term climate benefits of such systems.
For airports and large-scale food service operators in the Gulf region, EKFC’s example shows a practical way to reduce reliance on landfills while integrating renewable energy and electrification. Industry reports mention that automated feeding systems and integrated logistics are quickly becoming standard features for those looking to scale up food waste treatment without increasing labor costs too much. This trend fits well with the UAE’s plans for decarbonisation and the growing pressure for the aviation industry to demonstrate real sustainability progress.
EKFC’s rollout highlights the potential of combining on-site biological waste treatment with circular procurement, packaging redesign, and energy transition measures. They see the biodigester as part of a broader strategy, not just a standalone fix. As throughput and biological maturity increase, the real tests will be how steady the operation stays, how transparently emissions are accounted for, and how effectively they can reuse outputs back within the airport environment. If those factors stay aligned, this approach could serve as a model that other high-volume caterers in the region might follow.
