Composting Food Waste

Composting food waste in this Alaska composting facility http://www.alaskawaste.net/composting.htm with the in vessel composter from XACT has proven

Odor control is easily achieved with the BioReactor from XACT Systems.

For better moisture and odor control, this composter has duct work exhausting air out of the vessel through the discharge end of the composter. If need be, the exhausted air / duct work could be direct to a biofilter.

successful–just as expected!  The 10′ x 32′ BioReactor processes 10 yards of organic waste per day.  Striking the right balance of feedstocks with the rotation of the BioReactor and control of the ventilation has resulted in good

quality compost production.

This in-vessel rotating drum composter is composting food waste, and interestingly enough, the amendment is horse manure.  The operators of this facility know that in order to get good quality compost out, they need to put the right blend of feedstocks in.  The constraints of the blend consists of:  1) a proper percentage of moisture and  2)  the correct proportion of Carbon to Nitrogen.  Because the food waste stream on its own did not meet these constraints, there needed to be an amendment added to the food waste.

Composting Food Waste Amended With Horse Manure

The horse manure was available and also needed to be disposed of, so this composting facility determined the right blend of these 2 waste streams, and are now indeed, producing very good compost.  No less than a triple win! Using negative ventilation, clean air is drawn into the vessel, and the exhausted air is captured in the duct work located at the discharge end of the BioReactor.  The air is directed to a biofilter for filtration before being released to the atmosphere.

1700 Cow Dairy Composts Dewatered Manure for Bedding

The XACT BioReactor on this dairy operation is 10’ diameter by 60’ long. It has to turn 45 to 50

This 10'x 60' In Vessel Composter by XACT will compost manure for bedding from the 1700 cow herd.

tons of dewatered cow manure 240 times per day, 365 days per year. It had better be built strong!

After taking a look at the robust mechanical characteristics of the XACT BioReactor drum and the heavy duty drive system, this dairy operation was confident in the ability of the XACT system to handle the staggering weights of waste material to be processed daily. Check out all the specs for the BioReactor by clicking on xactsystemscomposting.com/bioreactor/

Dewatered cow manure is fed into the vessel by a conveyor. Because the infeed opening is located in the upper left

quadrant of the stationary infeed end, the BioReactor can be filled to 70% capacity. Remarkably, a 7.5 hp variable speed drive turns the BioReactor and its load.

After a 4-day retention period in the vessel, the discharged compost is taken back to the barn to be used as bedding for the herd. Upon discharge the compost is pathogen free, weed seed free, insect larvae free, and odorless. At this point the compost is about 50% moisture, and therefore as it gets blown into the stalls there is minimal airborne dust. Most importantly, the cows love it as it provides exceptional comfort.

Poultry Plant Processing Sludge & Hatchery Waste

This installation is operating with 3 BioReactors in order to quickly compost multiple waste

streams (slaughterhouse sludge, hatchery waste, wood chips).  2 of the composters are permanently situated and the smaller third composter is temporarily in place to conduct trials of various other organic waste streams.

As you can see, these vessels are housed under a single roof.  The land requirement for this composting system is pretty small compared to other methods of composting which would require a large acreage to compost the same amount of waste.
