Passive Aeration

Passive Aeration happens in non-reactor systems and includes: Triangular Windrow, Mat Windrow, Sole Aeration, Chimney Aeration, and Dome Aeration Technology (DAT) .
DAT is considered one of the cost efficient practical methods for aeration of compost winrows. Dome Aeration Technology is an open, non-reactor system where the degradation process takes place in a static (no turning) windrow. Continuous natural aeration is achieved by thermally driven advection, caused by temperature differences between the degrading material and the outside environment.
