In-Vessel Composting System

The BDP In-Vessel Compost System is widely recognized as the most space efficient type of system to achieve a stable, homogenized compost. The combination of an enclosed facility, agitation, and aeration creates an environment with no significant or persistent odor issues outside of the facility, allowing facilities to be built within 400 ft of commercial and residential areas.

The three proven methods of enhancing the natural composting process are: enclosing, agitating, and aerating.


  • Enclosed – For prevention of odor emissions and to minimize weather impacts
  • Agitated – To Maintain: pile porosity, end product consistency
  • Aerated – To Maintain: Aerobic conditions, control pile temperature

Recent Improvements:

  • Fully automated facility ability
  • Touch screen panels on compost agitator/dolly
  • Radio Communication/control ability to offsite locations as desired

BDP Compost Installations:

The BDP ICS compost technology has been used in many compost facilities, some within 400 ft of commercial and residential areas, with no significant or persistent odor issues.

  • Oldest Facility in Operation: 34 years
  • Site Locations: 33
  • Machines Built: 138
