When composting manure for bedding, how long does the manure remain in the BioReactor?

With the BioReactor, composting manure for bedding allows you to produce bedding to meet your specifications.  By adjusting the time that the manure is kept in the BioReactor, you can determine the quality of bedding that is produced.

Quick Time:  If you choose to simply dry the manure for bedding then the manure is kept in the BioReactor for shorter period of time (18 to 24 hours).

Compost Time:  If you choose to convert the manure to compost then the manure is kept in the BioReactor for 72 hours at a temperature of 150o F.

What sizes are the BioReactors?

The BioReactor is available in 5’ to 10’ diameters and up to 60’ long.  Determining the appropriate size of BioReactor is based on the volume of organic waste material and amendments to be composted.

What sorts of waste can be composted?

Any solid organic material can be composted such as:

How long does the waste remain in the BioReactor?

The time that the waste remains in the vessel is called retention time and this can vary depending on the type of waste to be composted. Typically, 4 days is sufficient to achieve compost that is about 75% mature (decomposed) and pathogen free.

Is a curing period required?

Upon discharge from the BioReactor, the compost is about 75% mature. In order to obtain maximum maturity, the compost should be cured for an additional 21 days or so (the length of time can vary). During this period, the compost should be sheltered.

How is pathogen-free compost achieved?

XACT Systems follows the EPA Rule Part 503 as a guide to it’s organic conversion protocol. These basic guidelines of composting are applied to any type of organic waste, which may or may not have the potential for human contact. Following these simple but precise guidelines will ensure the reduction of Pathogens, Viruses and Vector attraction.

EPA Rule Part 503

Viruses and pathogens can be reduced to undetectable levels through proper composting. In addition, vector attraction can be reduced to almost zero with proper composting techniques.

Are there tests of the compost certified?

Absolutely. All raw material and compost testing is conducted by an independent lab such as A&L Labs, an international laboratory specializing in environmental and agricultural analysis.

Is heat added to the system?

No. The bacteria that are naturally living in the waste material generate the heat as a by-product of the decomposition process. The BioReactor is insulated so that heat is not lost to the ambient air.

Will the BioReactor work in sub-zero temperatures?

Yes. The heat that is generated by the bacteria is maintained because the vessel is insulated with 2” of insulation and if necessary an optional heater can be added to warm the air at the intake opening.

How does the BioReactor make compost so fast?

It does so by tightly controlling the factors that are needed for natural decomposition to occur. The reason being is that the vessel provides a perfect environment for the decomposition process by the naturally occurring aerobic bacteria to take place by controlling all the factors—moisture, oxygen, temperature, carbon and nitrogen—within the specific parameters that good composting requires (Mother Nature’s rules!).

Does the XACT In-Vessel BioReactor qualify for government funding?

Yes, but the funding varies depending on your market sector and location. Please contact us for details.

Can you help me sell my compost?

Very likely yes! We have networked with compost companies that will buy your bulk compost. Please get in touch with us for more information.

Where can I see an XACT BioReactor in operation?

Please contact us and we can let you know.

What can I use the compost for?

Erosion control. Studies have shown that compost is great for controlling erosion of embankments and hillsides whether they are adjacent to roadsides, creeks, lakes or wherever—the stuff really works!

Soil amendment. Compost improves moisture retention capacity of soils, adds nutrients, and improves soil condition and structure. Scientific studies show that field soils show measurable benefits from compost—even after 8 years from the initial application.

Soil remediation. Organics conversion degrades volatile organic compounds, and many types of contaminants in soils, plus it binds heavy metals so they are not plant available. We can even help you produce “designer compost” specifically tailored to a particular pollutant. Call and ask us about this.

Animal bedding. Composting manure for bedding using the BioReactor results in pathogen free, dry bedding.  It provides maximum comfort and a healthy environment for any type of animal.

Flower beds, golf courses, parklands. Most gardeners would give their “eye teeth” for great quality compost that is weed seed free.
