Leachate System
Leachate is liquid that drains from the waste. This simulation shows:
- Generation based on moisture content
- Flow through waste layers
- Collection at the base
Gas Collection
Biodegradation produces landfill gas (mainly methane and CO₂):
- Gas generation depends on organic content
- Vertical wells collect gas
- Can be used for energy production
Waste Layers
Waste is placed in compacted layers:
- Daily cover reduces odors and pests
- Intermediate cover separates waste lifts
- Final cover seals completed landfill
Settlement
Waste compacts over time due to:
- Mechanical compression
- Biodegradation of organics
- Moisture movement
