EMISSIONS CONTROL IMPROVES AT HELSINKI-VANTAA

Airlines use propylene glycol and hot water to retard and remove ice from aeroplanes. At Helsinki-Vantaa the aircraft treatment areas are clearly indicated, the apron drainage system has been improved in recent years and more effective use has been made of suction vehicles so that the glycol that spills from wings can be channelled for wastewater cleansing, thus preventing it from entering the runoff water.

In 2005 the CAA initiated a project aimed in the next few years at transferring some of the ice prevention and de-icing treatment to a specially built centralised de-icing area adjoining Runway 3. Transferring aircraft anti-icing and de-icing to a new area requires stringent planning and cooperation with the operators. However, a central de-icing area will further improve control of glycol runoff.
