Airports are among the busiest hubs on Earth, serving millions of passengers every year. Behind the terminals, catering facilities work nonstop to prepare food for lounges, restaurants, and inflight service. These operations produce tremendous amounts of organic waste—from buffet leftovers and kitchen prep to unused inflight meals. Managing this waste efficiently, securely, and hygienically is one of the biggest challenges in airport food service.
The Traditional Approach: A Risky, Resource-Heavy System
Most airport catering facilities rely on external haulers to remove food waste. While this may seem straightforward, it introduces serious drawbacks in a secure, fast-paced environment:
- Security risks: Each pickup requires access to restricted areas, adding potential vulnerabilities.
- Logistical challenges: Waste often needs to be transported through or around passenger zones.
- High costs: Frequent pickups drive up operational expenses.
- Delays and hygiene issues: Waste may sit for days before removal, leading to odors and pest risks.
- Worker strain: Staff must manually handle heavy bins and bags, increasing the risk of injury.
In an industry where safety, efficiency, and cleanliness are mission-critical, this system is far from ideal.
Why the LFC Biodigester is a Game-Changer for Airport Catering
On-site digestion for seamless operations
The LFC biodigester from Power Knot is an aerobic digester that processes food waste on-site in under 24 hours. By converting waste into grey water safely discharged down the drain, it eliminates the need to move food waste outside the facility—or even out of the kitchen.
Hygienic, secure, and cost-effective
Because the biodigester is fully enclosed and odor-controlled, catering operations no longer need to worry about rotting waste, pest infestations, or unpleasant storage. No pickups, no trucks, and no delays.
Safer and more efficient for staff
With the LFC biodigester, staff no longer need to lift, haul, or store heavy containers of food waste. This reduces injury risks and frees employees to focus on food preparation and customer service instead of waste management.
Actionable data for smarter operations
The system automatically records the amount and type of waste processed. Catering managers can use this data to refine purchasing decisions, adjust menu planning, and accurately report on sustainability goals—vital in an industry under increasing pressure to reduce environmental impact.

Proven in Real-World Airport Operations
Air Fayre is a prominent in-flight caterer based in Gardena, California, that specializes in providing food and beverage services for passenger and cargo airlines. With a focus on operational excellence and a unique split-catering model, they serve major airlines at LAX and other Southern California airports, as well as charters for professional sports teams and dignitaries, and cater over 4.7 million meals for 54,000+ flights annually.
In September 2023, they replaced an unreliable system at their catering facility with an LFC-300 biodigester. In just its first month, it processed 14,000 lb (6,500 kg) of food waste—demonstrating both capacity and reliability from day one. The switch reduced waste-handling complexity and improved operational continuity, backed by Power Knot’s responsive technical support.
