The smart recycling bins used in the trial scheme are equipped with odour abatement devices and adopt an impermeable and enclosed design.
Additionally, the odour will be dispersed in the air as the bins are usually installed in outdoor and fully ventilated places. The department stressed that it is inappropriate for the company concerned to use indoor air quality objectives for comparison with the smart recycling bins placed outdoors, and claim that air pollutants generated from the bins exceed the prescribed threshold by 10 times.
The department also pointed out that residents responded positively to the design and operation of smart food waste recycling bins. They actively participated in smart food waste recycling with an increasing quantity of food waste collected
Currently, six public rental housing estates including Shek Pai Wan Estate in Aberdeen, Choi Tak Estate in Ngau Tau Kok, Sheung Tak Estate in Tseung Kwan O, Lin Tsui Estate in Chai Wan, Kwun Lung Lau in Kennedy Town and Tin Heng Estate in Tin Shui Wai have participated in the trial scheme.
