Bion Environmental Technologies, Inc. announced that a fourth patent related to its third-generation technology platform (3G Tech) was recently issued by the U.S. Patent and Trademark Office. Bion's 3G Tech provides advanced livestock waste treatment that will largely mitigate the environmental impacts of large-scale livestock production, recover renewable energy and high-value coproducts from the waste stream, and enable a USDA-certified Sustainable and/or Sustainable + Organic brand. The new patent, No.

11,254,581, is a continuation of the original 3G Tech patent, No. 10,106,447, that describes the separation, concentration, and crystallization of ammonium bicarbonate from the livestock waste stream, without the use of outside chemicals. The new patent expands those claims to include additional recovery methods, as well as processes that improve efficiencies and reduce capex and operating costs.

Bion's 3G Tech is now covered by four issued patents. These include No. 107,934,458 that was issued on October 6, 2020, which significantly strengthened Bion's IP position, not only by covering methods used at that time, but also by laying a foundation for future developments (for press release, click here).

Bion anticipates filing additional patent applications related to these continuing developments, including the optimization trials that concluded February 2021.
