In-vessel composter is composting dewatered dairy cow manure.

This BioReactor is 10′ x 60′ long and is composting 120 cubic yards of solid organic waste per day. The waste is resident in the composter for 4 days; therefore, the daily throughput is 30 cubic yards per day.


In-Vessel Composter: The BioReactor

The XACT BioReactors are large scale in-vessel composters that convert huge volumes of solid organic waste into compost in as little as 3 to 7 days. The XACT BioReactor 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!


The BioReactor in-vessel composter rotates at 10 rph, and is driven by a  4-D Friction Drives Power the In-Vessel Compostersurprisingly low hp motor. The size of motor depends on the size of the vessel but ranges from 5 to 10 hp.  Note that the ends of the BioReactor are fixed and only the cylinder rotates.

There are no temperamental interior plungers , fins or paddles. The organic material simply moves along the vessel as it decomposes and becomes lighter and fluffier.
