Supercharge Biogas Production

Boost Digester Biogas Production and Methane Content for Higher Methane Capture

Accelerate, Increase, and Stabilize Digestion Process at Any Facility

iBioBooster Systems™ (iBB Systems™) apply bioacceleration and bioaugmentation to increase a digester system’s methane capture

At industrial-scale digesters in Italy and China, iBB Systems have raised production of biogas and percentage methane content, increasing digester methane capture in the range of 10% to 25+%

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
v
Typically is housed in a container-sized unit (fermenter tanks can be located outside container) sited near an existing digester, operating off-line of the digester but connected to it.
Uses only microbes already present in the host digester system and standard nutrients.
Complements other measures that enhance host digester efficiency.
Can be applied at digester systems of any design processing any organic feedstock or combinations.
BB functionalities can be integrated in the design of new digester systems.

What an iBB System Does

Combines bioacceleration and bioaugmentation to increase a digester system’s biological 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 and its stabilization

Enhances Microbial Resilience

Improves the stability and resilience of a digester feedstock’s native methane-producing microbial populations

Boosts Methane Capture

Accelerates and increases a digester’s production of biogas with higher methane content
“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.”

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Samples (1-3 cubic meters each) of a digester’s organic material are regularly withdrawn and sent to the iBB unit for analysis and methanogen enrichment.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 nutrients and chemicals — an iBB System accelerates reproduction of methane-producing microbes, increasing populations in the sample as much as 100 thousand 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.

Proven iBB System Success in the Field

Real-World Performance Enhancements at Anaerobic Digester Sites

BB Systems designed by Chief Scientist Luciano Pesce have been deployed at large-scale anaerobic digester facilities in Italy and China, achieving significant increases in methane capture.

Host system performance improvements typically range from 8% to 40% increased biogas production with higher percentage methane content, resulting in significant increases in methane capture per unit of feedstock.

Increases over baseline methane capture have exceeded 25%
