Bion Announces Approval of New U.S. Patent that Broadens Protection for the
Company's Livestock Waste Environmental Treatment Processes

June 30, 2009.  New York, New York.  Bion Environmental Technologies, Inc.
(OTC BB: BNET) announced today that it was notified that its U.S. Patent
application 11/592,513 entitled "Low Oxygen Biologically Mediated Nutrient
Removal" has been approved.  The patent application was made on November 6,
2006; upon publication and issuance, the patent will be officially granted
and will remain in force until November 5, 2024.  This new patent strengthens
Bion's protection for the process's ability to convert and remove
phosphorous.  In addition the patent provides wider process configuration
coverage, greatly enhancing the ability to provide flexible treatment systems
to Bion's clients.

James Morris, Ph.D., P. E., Bion's Chief Technology Officer, stated, "This
new patent describes the removal of phosphorus utilizing a new and unique
process and system configuration.  Bion now has in hand a very broad array of
patents protecting variations and enhancements of the core Bion process.  The
Company's IP portfolio at present includes ten U.S. patents, as well as
patents in Canada, New Zealand and Mexico, with an additional U.S. patent
applied for and pending, along with patent applications 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.  Bion's system can be configured to
simultaneously reclaim renewable energy from the 'waste' biomass in a highly
efficient process.

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 more information, see Bion's website:
