Korean Airline Catering is the largest caterer in Korea.
The facility is designed for meal production for passengers and includes a big dish washing area for incoming trays from the flights.
The Envac system has a capacity of 60 000 trays/day.
The waste from the trays is automatically removed.
In the catering area there are 9 inlets in total. The waste is put in 60 litres plastic bags for later transporation by the vaccum system.
The waste is transported by vacuum in an underground pipe net to a collection station in the same building, where the full containers are picked up by truck.
Since the system is fully closed the hygiene will be significantly improved.
