In-Vessel Containers

Systems ECS Staff 07/29/2021

The ECS In-Vessel Container system provides the same environmental and process controls as the In-Vessel Tunnel systems, but with several unique advantages: these vessels are mobile; they are picked up, moved, and emptied with a roll-off truck.  This makes them a good choice for smaller facilities with limited area, sites that may need to be moved in the future, or for facilities that need to minimize construction costs and complexities.  This technology is generally best for facilities composting less than 50 tons per day.

CV ComposterTM

The CV ComposterTM (Containerized Vessel) is a modular in-vessel composting system designed for small, to medium-scale composting facilities that require comprehensive environmental control. It requires minimal infrastructure and the modular
approach easily adds additional capacity to accommodate growth. The CV’s advanced control system and unique aeration
design optimizes compost stabilization and pathogen reduction rates; while capturing and dramatically reducing VOC, GHG,
and odor emissions. The CompTrollerTM aeration control and monitoring system requires little or no operator intervention
during composting, and automatically records pertinent data for every compost batch.

Standard Features:

  • A batch system accepts a broad variety of feedstocks at irregular loading rates
  • Excellent odor control with completely sealed aeration design and biofilters
  • Constructed for a long service life
  • Built-in condensate management system
  • Semi-automated vessel loading conveyor system
  • Integrated vertical or horizontal auger compost mixer


The CV vessels are fabricated with stainless steel interiors and stainless or galvanized metal exteriors. The 40 cubic yard vessels are designed for compatibility with local roll-off system chassis. The vessels are
completely sealed and collect leachate/condensate in the aeration floor. The vessel walls, ceiling, floor and doors are well insulated.


The aeration system provides reversing and recirculating process airflow to control and maintain uniform biomass temperatures. Process air is scrubbed through an ECS designed biofilter built on site. All
components in contact with the compost’s corrosive airstream are made from either stainless steel or polymeric materials. The aeration system is designed to conserve energy with variable speed fans, a unique low-friction aeration floor, and adaptive control strategies. Motorized dampers control airflow and direction to each vessel. Damper positions are automatically set by the control system.


ECS’ CompTrollerTM is an automated aeration control and monitoring system that is operating at all ECS compost installations. It is designed to achieve regulatory compliance; offers operators a broad range
of process options; and provides each vessel with independent and automatic control for achieving process goals. The CompTrollerTM is remotely accessible via the web and is flexible, robust, and keeps your data safe.
