Beginning in September 2014, Bion began filing patents on its 3rd generation (3G) technology that is designed to recover substantially more value from the waste stream than its 2G platform, while maintaining or enhancing treatment capabilities.

The 3G platform uses anaerobic digestion to produce biogas (methane). The residual digestate contains dissolved ammonium bicarbonate, which is the focus of Bion’s patented ammonia recovery system. The residual solids, another energy and nutrient source, contain the remainder of the nitrogen, phosphorus and micronutrients. All processes are monitored and third-party validated, as with Bion’s 2G platform, so that renewable energy and nutrient credits, along with branding data, are generated and verified.

The original 2014 patent application was recently reinstated, after being abandoned in error. In September 2015, a second patent was filed that was issued in October 2018, becoming the first 3G patent issued. In July 2017, the 2015 filing was continued with its protections broadened; in January 2020 Bion received a Notice of Allowance on that filing. Additional patent filings are anticipated.

A number of small-scale 3G pilot studies were completed throughout 2016, 2017 and 2018. A final small scale pilot was completed in 2019, which successfully produced material for an initial application to OMRI (Organic Materials Review Institute).

To learn more about the 3G platform, please review the following press releases:

Bion’s 2nd generation (2G) Comprehensive Environmental Management System removes up to 95% of the nutrients (nitrogen and phosphorus) from the livestock waste effluent and substantially reduces air emissions, including ammonia (as great as 90% or more), greenhouse gases, hydrogen sulfide, VOC’s and others. The system extracts renewable energy from the waste stream in the form of cellulosic biomass. The technology is patented and proven at commercial scale.

Bion’s core 2G technology is a biological process that facilitates the growth of large populations of naturally-occurring bacteria that are responsible for the conversion of the nitrogen and phosphorus in the waste stream. Some of the nitrogen is released to the atmosphere in the form of harmless and inert nitrogen gas (N2). Most of the remaining nitrogen, as well as phosphorus, is converted by the bacteria into solid or particulate forms that are removable by centrifuge and other processes. Bion’s technology achieves 75 to 80% reductions of nutrients in the effluent; further treatment can increase the reductions to up to 95%. The system provides an expected pathogen reduction of three to nine orders of magnitude (three to nine log kill) depending upon the level of nutrient treatment employed at a particular site.
