Physical Properties of Waste

There are three physical properties of Solid Waste.


  • Density
  • Size Distribution
  • Moisture Content


Density:
Density is the mass occupied by a unit volume of material. A high density waste capture system can reduce the volume in a solid waste management system, which substantially reduces the cost of :


  • Collection
  • Transportation
  • Final disposal


Density Plays an important role in choosing the size and nature of collection vehicles.

Size Distribution:
Size distribution is important in designing collection vehicles and mechanical recovery systems, and in designing biological treatment methods.

Moisture Content:
Moisture content is defined as the ratio of the amount of water present to the total weight of waste material for a given waste stream.
