The XACT BioReactors are large robust rotating drums with fixed ends that convert huge volumes of solid organic waste into compost in as little as 4 to 7 days.
The XACT vessel is available in 5’ to 10’ diameters and in lengths from 10’ to 60’. Although it is a simple design, it is built to heavy-duty standards in order to withstand the rigors of turning tons and tons of material 24 hours per day, 365 days per year.

For example, a 10’ x 60’ long BioReactor is turning 75 tons of waste up to 240 times per day!                       


  • Carbon Steel Walls (up to 5/8” thick)
  • Solid Steel Wheels
  • Heavy Duty Mounting Frames
  • Wear Bars for durability
  • Interior Liner Rings
  • Negative Ventilation System for Process and Odor Control
  • Foam Insulation for 24/7/365 Temperature Control
  • Automatic Discharge Door
The BIoReactor’s interior with steel channel for added strength
The BioReactor rotates at about 5 to 10 rph, and is driven by a variable speed drive unit(s) using a surprisingly low hp motor.
The size of motor depends on the size of the vessel but ranges from 5 to 25 hp.


4 Friction Drives Rotate the BioReactor

There are no temperamental interior plungers , fins or paddles. The organic material simply moves along the sloped rotating vessel due to gravity.
  • Requires no supplementary heat
  • Offers tremendous throughput
  • Saves labor
  • Requires minimal land

Soft Touch Screen Control Panel

  • Optimizes processing factors
  • Controls ventilation, drum rotation, temperatures
  • Temperature Tracking

Site Layout

This 3-vessel system shows a feed stock prep building with a grinder and a mixer, and a 5-bay compost storage building. In addition, there is a biofilter installed in the ground along the length of the lower drum which is cleaning the air that is being drawn off by the exhaust system of the vessels.

Odor Control Using BioFilters

One of the great advantages of the XACT BioReactor is that as your operational needs increase additional drums can be added easily increasing your capacity with no down time. This is just one of the many possible layouts that could be designed for you!
