CompoBox™ Tunnel System
Excellent Odor and Emissions Control
The CompoBox™ Tunnel System is a completely enclosed Aerated Static Pile composting system, with all emissions captured and treated in a biofilter or geomembrane cover. Automated irrigation and hydraulic doors simplify operations and speed up the composting process.

How It Works
Compost feedstocks are mixed and loaded into the CompoBox™ Tunnels via front end loader. Computer controlled aeration systems regulate airflow, optimizing decomposition and controlling emissions through a treated exhaust system. By lowering the headspace, treatment costs and footprint are reduced when compared to composting in a building. After three to four weeks of aeration ready-to-cure compost is emptied from the tunnel for curing, screening, and sale.
