Stacks of folded cardboard boxes, computers, and even a microwave oven lay on the floor at the basement of Changi Airport's Terminal 2 on Friday.
The items were part of some 3,365 kgs of waste collected from airport staff in a recycling effort by the Changi Airport Group (CAG).
The first-of-its-kind initiative, which saw similar collection points set up at Terminals 1 and 3, drew support from CAG staff, as well as other companies like SIA Engineering and Emirates Airlines.
Staff members wheeled trolleys of unused documents, old newspapers and disused electronic peripherals like keyboards and monitors to the collection points from 10am, and the items were then sorted and taken away by recycling firms.
The airport's recycling efforts did not stop there.
It also sent off 11,000 used fluorescent lamps - collected from lamp replacement exercises conducted every one to two years - to be recycled,
In total, Changi Airport has about 200,000 light fittings.
"We don't know what to do with the waste most of the time, so we usually throw it away. So it's good now that we have this recycling day," said engineer Mr Muhd Raffi Ramat, 45, who works at Terminal 2's Data Centre.
