SD plant business summary
Because sewage discharged from the toilets of aircrafts
includes various chemicals unique to aircrafts that do not exist in ordinary human waste, there was a
high bar for its treatment. AFC considered the treatment of aircraft sewage as an important issue from
the start of its business, and acquired a patent for a sewage treatment method through research and
development. The company started the operation of the SD plant in Haneda Airport in 1980, and the
service was expanded to eight airports thereafter. This plant is provided as an infrastructure facility
that can be jointly used by airline companies and ground-handling companies. Sewage brought in is
treated with microorganisms in compliance with the effluent standards of municipalities, which also
contributes in the conservation of the water quality of rivers and oceans. In Haneda Airport,
construction of a new plant was completed in March 2020 in anticipation of an increase in demand.

Large aircraft washer facility business summary
The large aircraft washer facility is a place where airframes
are washed for preventing the corrosion of aircrafts, improving fuel efficiency, and for aesthetic
purposes. It is comprised of an aircraft parking space for washing, and a water supply and drainage
facility that treats the discharged water after the aircraft is washed. Water discharged after the
aircraft is washed contains grease and oil, sludge, and heavy metals, so it cannot be released to the
sewer as-is. Therefore, it must be treated in this facility so that it fulfills the standards to be
allowed to be released to the sewer. Our company contributes to the effective use of the limited space
within the airport by providing this aircraft washer facility as a shared facility that can be used by
different airline companies.
