Every year, the CAG Horticulture team works to beautify Changi Airport by maintaining our garden spaces and filling the airport with greenery specially grown in our airport nursery. In an effort to close the waste loop, the team has been actively diverting waste from our nursery and gardens to be used as compost.
An example of garden waste that we recycle are the withered stems of sunflowers. Instead of sending them to the incinerator, they are given a second life as compost. Sunflowers are especially suitable due to their high nutrient content and relatively short rate of composting.
Over the next few years, we plan to expand our recycling efforts to include more horticultural waste from our gardens as well as the trees and plants along Airport Boulevard.
