Composting System Types

Windrow composting
Applied at pile formation and during turning events.
In-vessel composting
Used in enclosed composting systems.
Aerated static pile
Used alongside forced aeration systems.
On-farm composting
Used by agricultural producers composting manure, crop residues, or processing waste.
