DO
The iBB System
A process comprising biotechnologies, hardware, and software
Developed specifically to realize the full energetic potential of organic wastes by prioritizing increase of a digester’s production of biogas and methane content as much as possible
Adds direct biological process management to whole-system process control.
Accelerates and stabilizes each digester system’s methanogenic processes to increase biogas production and percentage methane content.

What an iBB System Does
Combines bioacceleration and bioaugmentation to increase a digester system’s biological efficiency, resiliency, and methane capture
Accelerates Microbial Multiplication
Rapidly multiplies and sustains microbial populations already present in a digester’s microbiome central to the methanogenic process.
Enhances Microbial Resilience
Improves stability and resilience of digester system’s native methane-producing microbial populations
Boosts Methane Capture
Accelerates and increases a digester’s production of biogas with higher methane content
Our BIE technology applies intelligent, automated control of oxygen-requiring microbial communities to improve a variety of aerobic bioconversion processes.
How iBB Systems Work
iBB Systems use bioacceleration and bioaugmentation approaches to improve digester performance.
Sample Withdrawal
Samples (1-3 cubic meters each) of a digester’s organic material are regularly withdrawn and sent to the iBB unit for analysis and methanogen enrichment.
Accelerated Microbial Growth
Under optimized conditions — using only indigenous microbes present in the sample, and common chemicals, nutrients, and micronutrients —iBB Systems accelerate reproduction of methane-producing microbes, increasing populations in the sample as much as 100,000 times or more in a few days.
Bioaugmentation
Each enriched sample is returned to the digester system, bioaugmenting the digester system’s microbiome with boosted populations of its own native microbes.
Ongoing Cycle
The cycle repeats, building and sustaining the digester’s methanogenic microbiome and biogas production with higher methane content.
Phased Digester Systems
Multiple separate coordinated iBB Units can continually manage different microbial populations optimized for each phase or for combined phases of biogas production.
“Although academic knowledge about the microbiome, the engine driving the AD process, has been accumulating, the use of this knowledge for the innovation of anaerobic digestion technologies is still scarce.”
