Question 3 (a) After initial compaction in refuse collection vehicles, the compacted wet density is estimated to be 260 kg/m'. The following composition and densities of the solid waste are assumed before compaction, assuming that garden trimmings, wood, ferrous metals, and dirt and ashes are incompressible materials. Component Percent by Mass Wet Density (kg/mº) Food wastes 15 290 Paper 30 85 Cardboard 7 50 Plastics 5 65 Textiles 2 65 Rubber 0.5 130 Leather 0.5 160 Garden trimmings 8 105 Wood 6 240 Misc. organics 2 240 Glass 10 190 T'in cans 6 90 Ferrous metals 5 320 Dirt and ashes 480
Determine the volume reduction for the compressible materials, and determine the overall volume reduction of the solid waste.
