Emirates Flight Catering (EKFC) has taken a significant step in its sustainability journey by introducing a large-capacity, custom-designed biodigester to manage organic waste more efficiently. Installed at EKFC’s Central Commissary Unit, the Power Knot LFC-3000 enables the company to treat food waste directly at its source, cutting the need to send it to landfill sites.
The biodigester operates using aerobic digestion, a natural process that relies on oxygen, heat, and microorganisms to decompose organic matter. The output — grey water — can be reused for non-drinking purposes. Unlike traditional mechanical systems that gradually decline in efficiency, this biodigester improves over time as its microbial community evolves to handle a wider range of waste materials.
“At EKFC, we constantly look for areas where we can create real, lasting impact,” said Shahreyar Nawabi, Chief Executive Officer of Emirates Flight Catering. “Waste management is one of those areas. By treating waste responsibly and giving it a second life, we’re taking an important step toward our landfill diversion goals. This project’s success is a testament to our team’s collaboration, innovation, and daily commitment to sustainability.”
Since coming online in December 2025, the system’s capacity has grown steadily, currently processing around 3.5 tonnes of food waste every day. EKFC expects the facility will soon handle up to 6 tonnes per day once the biodigester reaches full efficiency.
According to emissions data aligned with the UK’s Department for Environment, Food & Rural Affairs (DEFRA), diverting one tonne of food waste from landfill can prevent roughly 0.7 tonnes of CO₂ equivalent emissions, mainly by avoiding methane release during decomposition. At full maturity, EKFC’s new biodigester could help cut more than 2,000 tonnes of CO₂e emissions each year.
The system is part of EKFC’s wider plan to weave sustainability into its core operations. The company continues to invest in clean energy and low-emission technology, including solar panels that generated about 4,000 MWh of electricity last year — offsetting nearly 1,600 tonnes of CO₂e. EKFC is also electrifying its ground fleet, with the region’s first electric hi-loader prototype set to debut by mid-2026.
In its ongoing circularity push, EKFC processed roughly 75,000 kilograms of food waste through its first biodigester last year and removed 45,000 kilograms of single-use plastic annually through packaging improvements.
The company has also created 47 new recipes that reuse production trimmings, while pesticide-free lettuce sourced from Bustanica supplied 28,000 fresh Emirates salads each day. Advanced automation and AI-based monitoring are further helping EKFC reduce waste and boost production efficiency.
