NEW YORK, Aug. 11 /EMWNews/ -- Bion Environmental

Technologies, Inc. (OTC Bulletin Board: BNET) announced today that it was

notified that its U.S. Patent application 11/106,751 entitled "Low Oxygen

Biologically Mediated Nutrient Removal" has been approved. The patent

application was made on April 15, 2005; upon publication and issuance, the

patent will be officially granted and will remain in force until December

26, 2021.



    Bion's new phosphorus removal patent coverage broadens and deepens the

Company's IP portfolio that now includes nine U.S. patents, as well as

patents in Canada, New Zealand and Mexico. Two additional U.S. patents are

applied for and pending, and patent applications are under consideration

for the European Union, Brazil, Argentina and Australia.



    Bion's patents protect its proprietary technology that uses biological,

chemical and mechanical processes to remove nutrients and other harmful

substances, as well as extract renewable energy, from high-volume

concentrated livestock waste streams. Bion systems provide effective

environmental treatment at a substantially lower cost than conventional

wastewater treatment plants that rely on expensive highly-oxygenated and

chemical processes. Bion's environmental management system is the only

technology able to provide a comprehensive solution to concentrated

livestock waste, through simultaneous removal and stabilization of

nutrients and reduction of air emissions including ammonia, hydrogen

sulfide, VOC's, greenhouse gases, odors and other pollutants, together with

reductions of pathogens, antibiotics and hormones.



    The new patent specifically protects the process's unique ability to

convert and remove phosphorus from the waste stream. Excess nutrients from

livestock waste, primarily phosphorus and nitrogen, have been shown to

cause serious environmental problems in the U.S. and worldwide. Bion's

technology employs a nutrient removal process driven by the system's active

biology that utilizes and metabolizes the waste stream to convert potential

pollutants to benign forms that can then be removed from the effluent

discharge stream.



    Bion's technology provides an effective solution to the environmental

issues faced by today's livestock industry. John Carlin, former Kansas

Governor and the Chairman of the Pew Commission on Industrial Farm Animal

Production, stated in the Commission's 2008 report that, "the goal of this

Commission is to sound the alarms that significant change is urgently

needed in industrial farm animal production ... the consequences are real

and serious and must be addressed." Bion's technology directly addresses

the various problems detailed in the report, which can be found on the Pew

Charitable Trusts' website (to access the complete report, follow the link

on the report summary at http://www.pewtrusts.org/news_room_detail.aspx?id=38438).

Bion's environmental treatment technology can be implemented on-site to

retrofit existing large-scale livestock facilities or in central processing

facilities, where waste will be transported from the farm to the Bion

system in areas with geographic concentrations of smaller-scale facilities.



    Bion's technology has been approved by the Pennsylvania Department of

Environmental Protection (DEP) (press release:

http://www.biontech.com/news/pressreleases/release20080520.php) to generate

verifiable nutrient trading credits for reductions of nutrient discharges

and ammonia emissions from dairies in a first-of-its-kind trading program

to help restore the Chesapeake Bay. These DEP-verified nutrient credits can

then be sold to municipal wastewater treatment plants (MWTPs) under the

Pennsylvania nutrient trading program and utilized by the MWTPs to offset

their nutrient reductions in lieu of upgrading existing facilities to meet

these more stringent nutrient standards. Pennsylvania's municipal

wastewater treatment plant upgrade costs (related to its Chesapeake Bay

Tributary Strategy) are projected at $1.2 billion. The adoption of Bion's

technology to treat livestock waste as an alternative to costly MWTP

capital programs can significantly reduce the overall compliance costs and

in the case of the smaller MWTPs can reduce that compliance cost by 75 to

90% of the projected plant upgrades.



    Mark Smith, Bion's president, stated, "The Chesapeake Bay and the San

Joaquin Valley are bellwethers for an environment that is challenged and

requires a solution to the environmental impacts of land application of

livestock manure. As the trend to require reductions of nutrients entering

our waterways continues and the cost of the potential solutions to achieve

those reductions is realized, we expect an increase in the use of

cost-effective livestock waste treatment to fill that need. With our proven

and commercial-ready solution, we anticipate the utilization of Bion's

proprietary technology to grow significantly."

    About Bion: Bion has provided solutions to the agriculture and

livestock industry since 1990, with 30 first-generation systems installed

through 2003. Bion's next-generation technology results from 18 years of

research & development, testing, commercial deployment, and further

adaptation to evolving standards and opportunities. In addition to

providing environmental treatment, the system recovers cellulosic biomass

from the waste stream to produce renewable energy in a process different

and much more efficient than others that seek to exploit this energy

source. The technology is scalable, proven and quickly gaining acceptance

by regulatory agencies and other stakeholders as an effective solution to

the environmental issues associated with concentrated livestock waste. For
