compaction landfill

essential to reduce settlement

take about 2 years

prevent fire

eliminates odour, flies & vermin

for building structure – 10 – 12 years

ideally compacted fill should have density of 900 – 950 kg/m3

densities are measure by using backhoe method and auger method.

the values depend on:

Type of waste

Pretreatment

Composting of waste

Time of landfill

Moisture content

Type of landfill

Stage of compaction

Leachate

define as liquid that has percolated through solid waste and has extracted Dissolved or suspended material

average amount of leachate generated is 150L//tonne

contain organic matter, nitrogen (ammoniacal), suspended solid salts & colouring matter.

constration of eluted matters will be highest the first 3 – 8 years.

quantity of leachate produced depend on factors:

Soil type

Waste composition

Degree of composition

Rainfall

Evaporation

Landfill type and age
