• Soil compaction
  Soil compaction
  In Geotechnical engineering, soil compaction is the process in which a stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water being displaced from between the soil grains then...

• Compaction (geology)
  Compaction (geology)
  Compaction refers to the process by which a sediment progressively loses its porosity due to the effects of loading. This forms part of the process of lithification. When a layer of sediment is originally deposited, it contains an open framework of particles with the pore space being usually...

• Waste compaction
  Waste compaction
  Waste compaction is the process of compacting waste. Compaction means to compress, condense or consolidate. It is often used to reduce the size of waste material. Garbage compactors and waste collection vehicles compress waste so that more of it can be stored in the same space...
