Covered Aerated Static Pile Composting
Aerated static pile composting is an improved version of windrow composting. Here too the waste is arranged in piles or rows. But an air pipe is provided underneath to augment oxygen supply and thereby prevent formation of anaerobic conditions. Typically, air is drawn through the pile with the help of a blower. The blower capacity is determined according to the established oxygen demand characteristics of the rotting waste.
The air flow rates can be adjusted according to the stage of rotting and the temperature attained in the core of the waste.
To this effect, appropriate probes can be inserted in the piles which are then coupled with a microprocessor for blower operation.
