Example 2-2
MSW is found to contain the following components:
3
No Components % weight Uncompacted Bulk Density (kg/m )
1. Food waste 22 290
2. Mixed plastics 12 60
3. Glass 8 200
4. Ferrous and aluminum 12 200
5. Textiles 5 60
6. Dust, dirt 28 500
What is the average density of this solid waste mixture?
Answer
Example 2-3
For the following waste mixture:
3
No Components % weight Uncompacted Bulk Density (kg/m )
1. Corrugated cardboard 25 30.0
2. Paper products 15 61.0
3. Aluminum 9 38.0
4. Food waste 29 368.0
5. Yard waste 22 7.1
a) What is the bulk density for the waste mixture prior to compaction?
3
b) Assume that the compaction in the landfill cell is 500 kg/m .
Estimate the volume reduction (expressed as %), during compaction in the landfill
c) If the food and yard waste is diverted for composting, what is the uncompacted bulk density of
the remaining waste?
