New Delhi: Airlines have said it is not possible to empty toilet tanks in mid-air as claimed in a petition before the National Green Tribunal.
An AirAsia India spokesperson said: “AirAsia India lavatory waste draining and disposal is outsourced to Globe Ground India (GGI). They collect the waste from the aircraft and dump it in an airport-designated waste dumping location.”
A Vistara spokesperson said the airline follows the procedures as per the Aircraft Maintenance Manual according to which waste is to be emptied into specialised waste carts.
“All necessary health, environment and safety procedure are taken while carrying out these activities,” the spokesperson said, adding that emptying toilet tanks is not possible mid-air in modern pressurised aircraft.
Jet Airways said ‘blue ice’, a term used for frozen sewage material leaked mid-air, as a “rare occurrence” which signifies “a leaking toilet system, leading to the formation of accumulation of ice in high altitude.”
In its order, the NGT had asked the Directorate General of Civil Aviation (DGCA) to issue a circular to all airlines using the Delhi airport to ensure that they do not release any waste while landing or taking off at the airport or near it.
It also asked the aviation regulator to impose an environmental compensation of Rs. 50,000 per violation of the circular and submit a quarterly report to the tribunal.
