Materials used for the construction of other facilities in the
landfill site (COF) represent concrete used for roads, storm
drainage and storage systems, monitoring wells, asphalt used
for the road, gravel or stone used as hard core for the road,
embankment and flood control channels, and steel used for
fencing and drainage pipes. The average consumption amounts
summarized from the aforementioned seven design reports
were 3.10 kg of concrete (with the range of 0.76.8 kg, n = 7),
0.930 kg of asphalt (n = 1), 6.79 kg of gravel (with the range of
2.513 kg, n = 7) and 0.051 kg of steel (with the range of
0.0120.15 kg, n = 4) for every one tonne of waste disposed
