Notes: (1) All figures are rounded off to the nearest ten.

(2) The waste concrete delivered to landfills as industrial waste since 2007 was re-grouped under Overall

Construction Waste. Its corresponding quantities have been deducted from Municipal Solid Waste.

(3) As from the edition of year 2004, the previously used complaint categories "Liquid" and "Water" are combined into one single category "Water" on the ground that both types of complaint are dealt with under the Water Pollution Control Ordinance.
