Composter Rotating Drum Technology

This BCS offers a “plug and play” opportunity to test various feedstocks and amendments, and blending combinations at the job site.

Projects in all market sectors based in China. It is equipped with the essential components and complete automation features required for most composting facilities….essential that is if the goal is to obtain high quality mature compost in 4 to 7 days!

The Model 515 BioReactor Composter Rotating Drum Technology

The BioReactor is a rotating drum composter that has a load capacity of 70% of the total volume of the drum. This composter is 5’ diameter x 15’ long. It features a fixed, spring-loaded in-feed end with an opening for loading; a fixed, spring-loaded output end with an automated discharge auger or door; a rotating vessel supported by 4 trunnion wheels, a Friction Drive (.75 HP motor), and a negative ventilation fan.

The Mixer

A mixer is needed in order to pre-blend all the feedstocks so that a homogenous mixture of all the materials is obtained. This Mixer is equipped with cutting blades to slash the feedstocks in order to

The blades on the rotating vertical auger slash into the organic waste material thus breaking it into smaller pieces. This slashing action is especially critical and necessary when whole vegetables or fruit are present.

reduce the particle size. The capacity of the mixer used on the Model 515 BCS is 50 cubic feet and has a:

The Conveyor

The BCS is equipped with a heavy-duty automated incline conveyor fortified with a cleated belt. The cleated belt prevents the pre-blended organic waste from sliding back down the conveyor as it is being automatically loaded into the BioReactor.

The Control Panel

The control panel monitors the composting process and controls the function of the mixer, the conveyor and the BioReactor. This is accomplished by the Timer/PLC Control on the Control Panel. Complete control of the system is thus at the finger tips of the operator.





XACT Systems Exhibits the BioReactor: An Innovative Composter

Are You Attending the US Composting Conference in Jacksonville, FL next month?

If so, stop in at the XACT Systems booth and find out more about the innovative composter:  The BioReactor!  Learn how to successfully compost food, yard and all sorts of municipal waste (including biosolids) rapidly.

Composter will compost yard waste, food waste, biosludge, and biosolids.

BioReactor Composting System with In-feed and Discharge Conveyors, BioFilter & Future Expansion Capability.

When you compost solid organic waste using the BioReactor, you will realize economic benefits (always a good thing),  and environmental benefits.  Converting waste into quality compost allows you to capitalize on the nutrient value of the waste and sell the resulting compost.  Because traditional methods of managing these wastes are incurring high costs, are creating health hazards and odor problems in the surrounding communities, there is a need to treat these huge volumes of organic waste with technological innovation.

The BioReactor Composter

The BioReactor Composter is a slowly rotating drum that converts any solid organic waste into compost.  It complies with the fundamentals of composting* regulations by tightly controlling the parameters of the composting process. This composter makes an ideal environment for the oxygen-loving bacteria to thrive and decompose the material in a highly aerobic process. The BioReactor will compost large volumes of organic waste quickly, and will do so without the occurrence of hazardous leachates or foul doors.

Indeed, the compost bears no resemblance to the waste from which it was produced.  This compost has tremendous value if sold in bags or bulk because it makes an excellent soil amendment due to its organic matter and nutrient content. The compost no longer has harmful bacteria in it to cause disease so it can be spread on land close to water sources.

* Composting is defined as a process of biological decomposition of biodegradable organic fraction of the waste, carried out by a diverse population of organisms under controlled aerobic conditions and other parameters (ratio of carbon: nitrogen, moisture, temperature, pH, particle size, porosity, homogeneity of the mixture).

If you are planning to go to the US Composting Conference in Jacksonville January 25-28, 2016, please visit us at booth 722.  Hope to see you there!

Composting Multiple Organic Waste Streams Separately? No Big Deal

Composting Multiple Organic Waste Streams Separately?  No Big Deal

Composting multiple organic waste streams separately is no big deal.  Do so with a very small footprint and in just 6-7 days–so now there is something to talk about!   This is all  possible with the BioReactor Composting Technology by XACT Systems.

Composting multiple organic waste streams separately? No big deal

Two full size BioReactors are composting 2 waste streams at an integrated processing plant. The 3rd smaller BioReactor is processing other waste streams on a trial basis.

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 each is composting a different organic waste. 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.

How the BioReactor Composting Technology Works:

The BioReactor  is an in vessel rotating drum that provides the perfect environment for the composting process to take place which means that the composting process happens very, very fast.   Small Land Requirement:   These larger 2 units are 10′ x 60′ (3m x 18m). Heat:  The continual rotation of the BioReactor controls the temperatures of the composting process in optimal range.  Oxygen:  Plus, ALL the tumbling waste material is exposed to the oxygen in the air at all times, so decomposition process is completely aerobic.  Capacity:  The BioReactors can process large volumes of waste per day…in this case each vessel is processing 22 tons per day.

Composting Multiple Organic Waste Streams Separately? No big deal

This Composting Facility with the BioReactor Composting System and curing area is located in Brazil.

In-Vessel Composting System is Put Through Its Paces and Performs Well

Our In-Vessel Composting System Is Being Put Through Its Paces and Performs Well

XACT’s in-vessel composting system is being put to the test in a pilot project using various solid organic materials and amendments.  One of the tests included small animal/bird mortalities as a feedstock.  Recently, one of the superb composts produced used the following feedstocks:

Composting food waste and other organic solid waste with the Compact BioReactor.

In-Vessel Composting System Using XACT Systems’ BioReactor for a
Pilot Project to Test Various Organic Waste Including Food Waste.

This project has been implemented  to confirm the BioReactor’s performance and to determine best practises for the composting process protocols  and feedstocks.  This in-vessel composting system is comprised of a 5′ diameter  x 10′ long vessel, a mixer and conveyor and is situated in a hoop building.  It has been running tests for approximately 6 months trouble free.  Satisfied with the pilot project results, this company is ready to take on the full “meal deal” and   get started commercially on a large scale with a 1060 BioReactor.

The Value of Pilot Projects

Pilot projects allow a facility to:

An in-vessel composting system, such as the Compact BioReactor, lend itself perfectly for pilot projects:

  1. The system is totally self-contained.  Typically, a mixer and conveyor come with the rotating drum in order to facilitate blending and loading.
  2. The BioReactor composting system comes completely wired and ready to go….just plug and play! (3 phase or single phase options)
  3. This composting system comes equipped with variable speed return air fan.
  4. The friction drive systems has extremely low energy requirements.
  5. The system is very quiet and pristine.
  6. The Compact composting system can be place on a flat bed trailer and moved from site to site.

Why Bury Money?

Why Bury Money? Why indeed!  But it is occurring everyday in every municipality on this continent.  At a time,

4 Friction Drives Rotate the BioReactor

4 Friction Drives Rotate the BioReactor

when city coffers are dry and nobody wants to raise taxes, a good source of new revenue is being sent to the landfill and being buried.  Solid organic waste when converted to good quality compost is worth $16.00 to $65.00 a cubic yard.   Imagine what the annual revenue stream could be on the thousands of tons of organics if only it were diverted.  Then imagine what could be done with the money.

I can hear the nay-sayers now…..”but the cost of setting up the composting system is prohibitive.” As the old timers used to say, hog wash!  The XACT BioReactor Composting System pencils so well because of its low operating costs, minimal manpower, land, and energy requirements.  The typical Return on Investment for a large system is 2 years or less.  Plus, it is clean system with ridiculously low odor, emissions or leachates.  The precise engineering and robust carbon steel construction of the BioReactor provides reliable 24/7 operation. Check out the website: and read about the success stories of others who have stopped burying their money (and are spending it!!!)

Composting Facility Design Composts 2 Separate Waste StreamsUsing 4 BioReactors by XACT

Site Layout for 2 Waste Streams and 4 BioReactors.

Site Layout for 2 Waste Streams and 4 BioReactors.

A composting facility design using 4 XACT BioReactors accommodates 2 different waste streams.  In this situation, the waste streams are biosolids and mixed solid organics.  Note the building in the foreground which has a wall dividing the tipping floor which keeps the waste streams separate.  The 2 vessels on the left compost one type of waste while the 2 on the right compost the other waste stream.  In this case, the discharged compost needed to stored for a period of time so it is automatically conveyed into the building in the background for that purpose.   One of the requirements of this facility being built is this jurisdiction was that there be odor control technology included.  Therefore there are 2 biofilters: one services the waste receiving building and the other services all the drums.    If you are thinking about how to design your composting facility, please give us a call.  The design possibilities know no limits.  Thanks so much for your time and consideration.  Doreen

In-Vessel Rotating Drum Composter Converts Food Waste to Compost

This in-vessel rotating drum composter is composting food waste, and interestingly enough, the amendment being used in 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 would need to be an amendment added to the food waste.  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!
