Global Community How To…
Produces bioethanol and electricity from carbon also called “carbonaceous feedstock” that can be sourced from:
• Agricultural Residues
• Distillers Grain (DDG)
• Green Waste
• Bio-solids & Animal Wastes
• Wood Wastes
• Municipal Solid Waste
• Bio-Diesel “Bottoms”
• Refinery Tars & Waste Oils
• Used Tires & Plastics
• Coal & Other Hydrocarbons
A patented microorganism ingests synthesis gas (gasified wastes) and emits pure bioethanol

The BRI process does not pollute. The emissions from the gasifier are fed to the microorganisms in the fermentation tank to assure all pollutants are eliminated.Does the BRI Process Pollute?
There are no air emissions from the gasification step. The syngas is treated through “scrubbing” and activated carbon filtration and then fed directly to the fermentation vessels.
Waste heat from the cooling of the synthesis gases is used to create high temperature steam.
Syngas remaining after the fermentation stage has high concentrations of hydrogen that can be combusted to produce additional high temperature stream or the hydrogen can be reclaimed for external markets.Air Emissions
5% ash remains from organic material. Inerts or inorganics such as metals or glass will remain in the ash for landfilling or recycling. We estimate that the combinations of ash from the organics and the inorganics will total approximately 15%.
Syngas is “scrubbed” prior to introduction to the fermentation vessel resulting in a waste water that is treated for recycling. Excess water is treated and suitable for irrigation uses.
Air emissions are minimal with low levels of hydrogen and CO2. The hydrogen can be reclaimed for available markets or discharged. The levels are far below U.S. EPA and international guidelines.
Produce ethanol from locally generated carbon rich feedstock derived from solid waste and sewage sludge
Reduce Dependence on Landfills
