Remarks:
The variation in density is due to different compositions of surplus
filling materials
There may be discrepancies in the total quantities with the quantities of
inert C&D materials stated in Appendix E and section 7.2.4, due to rounding
errors
No density was given from October 2017 to March 2018 due to the direct
volume figures as provided and confirmed by the RSS
