Some domestic waste was incinerated up to May 1997
(2) Public Fill = Inert C & D materials delivered to public
filling areas
(3) Predicted figures of population in 2001, 2006, 2011 from
the Planning Department under Scenario B of the TDSR
(4) Municipal Solid Waste received at disposal facilities
= (a) + (b) + (c)
(5) Total quantity of all waste received at solid waste facilities
= (a) + (b) + (c) + (d) + (f)
(6) Estimated mid-year population from C&S Dept.
(7) Waste Arisings Indicators: { (a) + (b) + (c) + (d) + (e)

* Figures shown are average of actual operation days rather
than 365 days during the year of commissioning

Tonnage of waste received by each strategic landfill each
year was calculated as follows: For year of commissioning:
Average daily intake (tpd) x No. of actual operation days
(ie 43 days for WENT, 97 days for SENT & 214 days for NENT)
For other years: Average daily intake (tpd) x 365 days
(4) Waste Treatment & Disposal Indicator: Total Remaining
Landfill Capacity by Volume = Designed Capacity minus Used
Capacity of all landfills
