Aerobic Bin

Design Considerations

Density of biodegradable waste

500 kg/m³

Retention time

45 days

30% of waste reduction will be considered due to leachate and volatile gas removal.
For one unit (2 bin) of Aerobic bin

Calculations

Volume of a bin (= 1.2 X 1.2 X 1.2 ) : 1.728 m³
Volume of waste that can be treated in a bin excluding of cow dung/inoculum :
1.512 m³
Volume of waste that can be treated in a bin considering 30% volume reduction : 2.16 m³
Waste can be treated in a bin (in kg) : 1080 kg
For Retention time 45 days : 24 kg/day
For one unit (i.e. 2 bins) 24 kg of biodegradable waste can be treated per day
Leachate collection facility shall be provided. Collected leachate can be used for agriculture purposes after dilution or may be used in the unit itself for accelerating the composting process.
