CPH removes waste from the three passenger terminals and from CPH’s maintenance facilities and administration buildings. Other companies are responsible for disposing of waste from aircraft and other activities on the ground, such as maintenance and catering.
CPH’s share of the total volume of waste at the airport amounts to 9 tonnes per day. CPH handles this waste by three different methods:
Recycling of waste from operations
Recycling of waste turns it into new raw materials. Recyclable waste accounts for 18% of the total amount of waste. Recyclable waste is primarily cardboard, paper and iron and other metals. Most of the recyclable waste is generated continually by airport operations, whereas a smaller and highly variable proportion is generated by various cleaning-up processes.
Incineration for district heating
Waste that cannot be recycled is utilised by way of incineration for district heating and power. Waste for incineration primarily consists of mixed combustible waste from offices, shops, kiosks and passenger areas in general.
Some waste contains environmentally hazardous compounds and is not suitable for recycling or ordinary incineration. This type of waste must be incinerated at special facilities, such as KommuneKemi.
Waste for special treatment primarily consists of water with a small content of oil and/or soap, e.g. from washing aircraft stands after oil spills. Two factors that affect the volume of this waste are the amount of precipitation and the time of year the collection tanks are emptied. As a result, there are large fluctuations in the volume of waste for special treatment.
Waste that is neither suited for recycling nor for incineration must be deposited to a landfill. This type of waste primarily comes from infrastructure maintenance and is not affected by changes in passenger numbers. The largest fraction for disposal to landfills is waste swept from streets and similar areas and waste vacuumed from stands and similar areas.
In 2014, the aggregate amount of waste was 4,501 tonnes. Waste per 1,000 passengers totalled 176 kg in 2014.
