Material density values used in this study.

Material Type	Density Values	Unit	Description
Concrete	2300	kg/m3	construction standard production unit system
Block	1900	kg/m3	construction standard production unit system
Brick	2000	kg/m3	construction standard production unit system
Mortar	2000	kg/m3	construction standard production unit system
Timber	590	kg/m3	construction standard production unit system for weight of dry wood
Slate	10.5	kg/m2	10.5 kg/m2 was used for weight per unit surface area of cement asbestos containing 10% asbestos
Roofing tile	198	kg/m2	one cement roofing tile: 5.5 kg, calculated for 36 tiles/m2
Glass/ceramic	2300	kg/m3	densities of sheet glass and ceramics range between 2100 and 2500 kg/m3, so an average value of 2300 kg/m3 was used
Plastics	1200	kg/m3	density of plastic used in buildings ranges between 900 and 1500 kg/m3, so an average value of 1200 kg/m3 was used
Household waste	300	kg/m3	density value of 300 kg/m2 was used for household waste according to a performance guarantee process guideline for processing abandoned waste, Regulation No. 249 by the Ministry of Environment
Soil	1600	kg/m3	dry soil weight
