Composting Septic Sludge Tests Prove Successful
Composting septic sludge in 5 days AND making compost that is pathogen free is possible with the BioReactor by XACT Systems Inc. In this testing project, the septic sludge is combined with other materials in order to make a balanced recipe of organics with a C:N ratio in the ideal range (20:1 to 30:1). This is the vital first step in composting solid organic waste quickly and making compost that is pathogen free. The second step is to compost this proper mixture in the BioReactor which is an in vessel rotating drum composter. The composter rotates slowly and constantly. The rotation tumbles the waste material inside the drum and exposes all of the material to the ambient oxygen. The aerobic bacteria which naturally reside in the organic waste will decompose it. The fact that all the bacteria are getting all the oxygen they need to do a great job of breaking down the material means that the waste will compost quickly and with little or no odor. The innovative features of this 5′ diameter x 10′ long BioReactor allow the temperatures of the composting process to hit temperatures of 145 degrees Fahrenheit to 170 degrees Fahrenheit and maintain it there. Once these high temperatures are achieved, the septic sludge is exposed to this heat for 72 hours (as per the protocol stated by the EPA standard for pathogen kill in a composting process). After 5 days, the compost is discharged and it looks and smells like dirt. It will make an excellent soil amendment and be a valuable revenue stream for this composting operation.
XACT Systems Inc. offers sincere congratulations to our partner in India, SFC Environmental Technologies Pvt. Ltd., which has been awarded contracts for 2 more large scale solid waste handling facilities in India.
These new facilities are mandated to compost 310 tons of solid organic waste per day. The composting technology that SFC has specified for these 2 operations is XACT Systems Inc. BioReactor Composting System from Canada. A total of 12 BioReactors will be built and installed by SFC, and each BioReactor will be 10′ diameter by 60′ long (3m x 18m). SFC has earned this contract on the heels of very recently and successfully completing 2 other large scale solid organic waste management projects in India that also featured XACT’s BioReator composting technology.

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 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).

Manure composting technology has proven economic and environmental advantages. XACT Systems’ Manure Composting Technology — The BioReactor is proving to be a wise choice by farmers in all animal farming operations including dairy, beef, horse, poultry and fish. How many farmers think that composting manure is a good manure management strategy? If so, how many farms are now using manure composting technology?
The XACT BioReactor on this dairy operation is 10’ diameter by 60’ long. It has to turn 45 to 50 tons of dewatered cow manure 240 times per day, 365 days per year. 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 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.
Please share your thoughts about composting manure. Many thanks, D.
