IGS has developed and patented an effective and efficient means of dealing with all general waste generated within the airport terminals and from onboard aircraft, with its Waste Processing System. This not only reduces the volume of waste by 80%, but also removes 50% of the weight by removing the moisture content within the waste.

The process relies on friction to generate heat during the cycle, which in turn allows the moisture to evaporate as steam, which subsequently sterilises the waste, killing any harmful germs and bacteria. The now dry, odourless, sterile, and inert processed waste (RDF) is dispensed into a holding chamber containing a vacuum bag. Once the bag is sealed, it can be stored for up to 12 Months.

The whole process cycle is complete within 25 to 40 minutes, depending on the initial moisture content of the waste. Under normal conditions the Waste Processing System can effectively deal with the waste of up to 250 passengers and staff, generating around 500KG of waste per day, in approximately 7 to 8 hours.
