New Video of the XACT BioReactor

Next week, we will be visiting the dairy farm in Wisconsin that recently purchased the 10′ x 60′ BioReactor by XACT.  It will be the first time we have seen it in action on the farm, so we are really looking forward to it. The top priority while there is to video the mammoth BioReactor rotating with the load of manure and capturing the infeed and discharge procedures.  Also, the new 4-D Friction Drives which are powering the BioReactor with only 3 hp motors on each drive will be of featured on the video as well.  Finally, I would like to get the movement of the discharge door on the video too.  Because it is such a simple (boring) machine that is it for moving parts.  If you would like to get a copy of the video, just let me know.  Better yet, if you want to see the BioReactor in action on the farm just get in touch any time.  Of course, I will get still photos as well, and will share them with you soon.  Many thanks, D

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!!!)

Compact BioReactor Next Level Pre-Mix

XACT Systems introduces our new pre-composting Vertical Mixer/Chopper for the Compact BioReactor.  The rugged vertical design of the tub with a cone-shaped auger offers superior mixing and chopping making a nice blend of your feedstocks and amendments.  The Vertical Mixer comes with an auger conveyor which quickly empties the tub of the materials and deposits them into the BioReactor through the infeed opening.

For added durability and dependable performance, the tub and bottom are made of stainless steel. As an option, this new vertical mixer and auger conveyor can be gasoline powered with hydraulic drive for those situations where an electrical power source is an issue.

Nothing is built by XACT that does not meet our Toughest Technology Rule.  Why so?  Because when you commit to an organic waste handling program, the equipment HAS to be functioning 24/7 because the waste material NEVER stops coming.

If you would like to see and learn more, please contact us anytime.  Many, many thanks.  D

Urban Composting Can Capitalize on the New Trend of Urban Farming

Urban composting with the BioReactor by XACT offers savvy businesses the opportunity to capitalize on the growing trend for local food production better know as Urban Farming.  Let’s talk about this new Local Food Movement and then see how the BioReactor fits into the picture.

A new study from The Ohio State University suggests that most modern cities have the potential to grow up to 100 percent of their current needs for produce and other items.  The study, “Can cities become self-reliant in food?,” conducted by Parwinder Grewal, professor of entomology and director of the Center for Urban Environment and Economic Development at Ohio State University, suggests that a city such as Cleveland, OH, could produce most of the food its citizens need.

The report states that “While not trivial, current local food production only accounts for 1.7 percent ($1.5 million) of the $89 million Cleveland spends annually on fresh produce, and 0.1 percent of the city’s total food and beverage expenditures. However, the potential for food self-reliance is significantly higher considering available space in the city.”

The study determined that Cleveland has more than 3,000 acres of vacant lots that are the result of years of manufacturing job losses, the recent economic downturn and a high rate of home foreclosures. He also found 2,900 acres of flat rooftops.

This study indicates that “the city can prevent economic leakage anywhere from $27 million to $115 million annually by increasing its production of fresh produce, poultry and honey. This could boost the city’s economy and lead to increased job creation.”  In addition, local food production has many other benefits, such as boosting access to and consumption of fresh fruits and vegetables; cut obesity rates due to consumption of healthy food and increased physical activity; promote a sense of community and decrease crime activity; and raise property values as vacant lots are put to attractive and productive use.

Urban farming can also reduce human impact on the environment. Professor Grewal said food in the U.S. travels an average of 1,500 miles from the farm to the consumer’s plate, requiring large amounts of fuel and energy for transportation and refrigeration. Additionally, increasing green space in the city through farms and gardens can boost carbon storage in the soil, reduce problems associated with stormwater runoff, and curtail the urban heat island effect.

“Just like the organic food movement, where it was about five to six years ago, the local food movement is gaining a similar type of momentum right now, and every city has the potential to at least increase its local self-sufficiency and resilience by producing its own food.”

This study certainly makes sense, and the BioReactor Mini, such as the 510 or 515  makes it a viable economic and environmental business endeavor.  All the features of the XACT BioReactor scream “Urban”.  From the fast throughput to the quiet operation to the odorless processing there is no better composting system for organic waste conversion.  Couple the BioReactor technology with the staggering food waste produced from schools, restaurants, hospitals, and grocery stores and then utilize the finished compost for Urban Farm–it makes cents (lots of them)!

BioReactor Composting System Goes Mobile

5' x 15' Mobille BioReactor with Mixer and Generator

5′ x 15′ Mobille BioReactor with Mixer and Generator

This BioReactor Composting Systems built by XACT is mounted on a rugged dual axle trailer for an operation which needs to travel from site to site–including remote locations. So, it has its own generator mounted on the front  (silver box).  The  entire system includes a  5′ x 15′ insulated BioReactor, a mixer/blender with conveyor, a control panel and the generator.  The volume of organic waste the 5 x 15 rotating drum can compost per day, based on a 4 day retention, is about 1.9 cubic yards (this value can vary depending on the waste to be composted and the length of time the waste remains in the BioReactor).  As you would expect from XACT, this mobile unit is available in other sizes of vessels and it can be made stationary as well.  Why you can even order this system with a bio-filter if need be.  It is perfect for pilot projects, R & D, institutional use, urban locations–the list goes on and on.   Feel free to contact us to discuss your next composting project.  Many thanks.  D

Field of Significance!

10' x 60' BioReactor

10′ x 60′ BioReactor

We got a call a while back from a very smart farmer who has been putting compost on a crop field for 3 years now.  In comparison, he has another crop field where he has not applied compost at all.  This spring when he worked up the fields, he made a significant discovery.  In the field without compost, he had to drive his tractor 2 miles / hour slower (than the composted field) and used 16 gallons/hour of diesel fuel. On the field with compost, he was able to drive his tractor 2 miles / hour faster and only used 7 gallons of diesel fuel / hour.  With the cost of fuel these days, this is truly a significant savings.  If you are looking for ways to cut operating costs, here is a sure fire one.  Plus, the in-vessel, rotating drum

BioReactor can turn your manure into pathogen free compost in 3 to 4 days which can also be used as bedding for the herd as well as a soil amendment. When you start to calculate ALL the savings, the XACT BioReactor offers a return on your investment which out performs any other piece of equipment you will have on your farm.  If this seems hard to believe, just give us a call to check it out for your farming operation.  Many thanks.  D

XACT Partners with Bulgarian Company

The XACT Systems is honored to announce that it has been selected by Nord Bio Ltd. of Bulgaria to become a new strategic partner in its commitment to providing economically viable solutions for organic waste management in Bulgaria and the European Union.

BioReactor: Strength of Steel

Turning tremendous weights of material in a rotating vessel demands the strength of steel for reliable performance over the long haul.  The BioReactor is built with carbon steel walls that are 3/4″ thick on our large units, and even our smallest BioReactors have 3/8″ steel walls.  (And you’ll never believe how thick the steel is of the riding rings…I will gladly share, so get in touch.)

If you are considering composting with the rotating drum technology and are conducting some comparative analysis, be sure to find what the drum walls are made.  If they are steel, it is important to also know how thick the steel is.   You will find out that some vessels are not even made of steel!   In addition, the engineering of the XACT drum includes steel bars on the inside of the walls that run the length of the drum for added strength.  Why build to such rugged standards?  The answer is easy…we want you to be confident in the performance of the BioReactor when you first press the Start button and for many, many years thereafter.    Please get in touch to learn more about the importance of steel in your next composter.  Many, many thanks.  D

Low Energy Consumption: XACT BioReactor

The hot button for many of the companies and organizations we meet with are energy costs and reducing energy consumption which is driven by soaring energy costs and, in some regions, lack of supply.  At the same time, tremendous amounts of organic waste must be managed in a responsible manner.  Thankfully, there is a viable solution, because the BioReactor by XACT solves both challenges handily.

Here are the facts and formulas to calculate the energy costs for a 10’ diameter x 100’ long BioReactor.  This size of vessel is run by one 10 hp electric motor.  The horsepower output for a 10 HP is 746 Watts X 10 = 7460 Watts = 7.46 KW. Accounting for the typical inefficiencies of the motor, let’s estimate it to be about 85% efficient, so the electrical input to the motor would be 7.46 KW / 0.85 = 8.78 KW. Operating for one hour, the 10 hp motor would consume 8.78 KW X 1 Hr. = 8.78 kWh.

According to the U.S. Bureau of Labor Statistics, the average cost of electricity (per kWh, nationwide, as of December 2010) is $0.125/kWh.  Thus 8.78 x 0.125 = $1.10

Thus, the energy costs for a 10′ x 100′ BioReactor is:

$1.10 for 1 hour of operation

$26.40 for 24 hours of operation

$792.00 for 30 days

$9,636.00 for 1 year

Now let’s look at how much waste is being composted.  The 10’ diameter x 100’ long BioReactor has a capacity of 200 cubic yards.  200 cubic yards of solid organic waste on average weighs 120 tons (assumption of 2 cu. yd. = 1.2 ton).  If the organic waste remains in the drum for a 4-day retention period, the energy costs for that period is   $105.60.  And what do you get for $105.6o?  At the end of the 4 days, you will have compost that is 75% mature and pathogen free.  Not only will you have composted all the waste for just $105.60, but  you will have done so and controlled emissions, VOC’s and odour.  So, the the bottom line is:

$105.60 to compost 120 tons of solid organic waste. How is that for low energy costs and consumption!  Let’s try plugging in your regions energy costs and see what your costs would be…call any time.  Many thanks.  D

BioReactor Wins Approval

The BioReactor drew much attention at the recent annual US Composting Council Conference and Trade Show.  The XACT technology is winning approval because of its capacity to:  reduce odor and leachate problems, eliminate the need for huge tracts of land, and offers tremendous throughput.  Many participants were excited to learn that the BioReactor offers better ROI than industry standards.  The smaller sizes were especially of interest at this conference.

The need to compost food waste on site at institutions such as hospitals, universities, schools, etc. was very evident, and the smaller BioReactors are perfect for these applications.  A BioReactor installation is clean, safe, quiet and professional.  The equipment meets OHSA safety standards.  The slow rotation of the BioReactor using a friction drive system is driven with a remarkable small hp electric motor.  This feature is hugely advantageous from the operating costs perspective as well.  If any of this information strikes a cord with you, please feel free to get in touch at any time.  Check photos of the units on our website (for some reason I couldn’t attach them to the blog this time).  Many thanks.  Doreen
