                     BION ENVIRONMENTAL TECHNOLOGIES, INC.

Construction Commences on Pennsylvania Dairy Farm Waste Management System
Which Will Produce Cost-Effective, Permanent, Measurable and Verifiable
Nutrient Reductions to the Chesapeake Bay

November 11, 2010. New York, New York. Bion Environmental Technologies, Inc.
(OTC BB: BNET) on Wednesday, November 10, 2010 held a groundbreaking ceremony
to mark the commencement of construction activities for its livestock waste
processing technology project at the Kreider Dairy Farm in Manheim,
Pennsylvania.

Joining Bion at the ceremony were John Hines, Deputy Secretary of
Pennsylvania Department of Environmental Protection, Paul Marchetti,
Executive Director of PENNVEST, Russell Redding, Pennsylvania Department of
Agriculture, State Sen. Mike Brubaker and Representative Tom Creighton.

"The Bion Farm Waste Treatment System is a shining example of the type of
ingenuity and innovation that we need to overcome the significant and unique
challenges we face in reducing pollution in the Chesapeake Bay," said
Brubaker, who serves as Vice Chairman of the Chesapeake Bay Commission and
Chairman of Pennsylvania's delegation to the Commission. "I am grateful that
Bion Environmental Technologies and Kreider Farms are leading the way in
helping Pennsylvania meet our pollution reduction goals to protect this vital
natural resource."

Bion has established a website (www.bionpa.com) to provide the Chesapeake Bay
watershed stakeholders and Bion shareholders with a transparent source of the
projects' status and, upon completion, the data and results that compose
Bion's credit verification plan. The Bion installation will demonstrate the
technology's ability to generate real, measurable, permanent and verifiable
nutrient reductions from unregulated non-point source livestock facilities
such as the Kreider dairy. Bion's approved credit certification plan is
unique in that it includes nitrogen credits from the reduction of ammonia
emissions. The measurable and verified reductions to both the local
watersheds and the Chesapeake Bay drainage basin will demonstrate the overall
cost effectiveness of treating livestock waste at the source. Stakeholders
and others will be able to post questions and comments that Bion staff will
respond to, subject to the limitations imposed by SEC Regulation FD.

About Bion: Bion Environmental Technologies has provided environmental
treatment solutions to the agriculture and livestock industry since 1990.
Bion's patented next-generation technology provides a unique comprehensive
treatment of livestock waste that achieves substantial reductions in nitrogen
and phosphorus, ammonia, greenhouse and other gases, as well as pathogens,
hormones, herbicides and pesticides. Bion's process simultaneously recovers
cellulosic biomass from the waste stream to produce renewable energy.

Bion's technology enables development of large scale livestock facilities in
strategic locations that provide greater efficiencies and dramatically
reduced transportation costs but were previously impracticable due to their
environmental impact. These environmentally-responsible, large scale
facilities can be integrated with existing or new food processing and
renewable energy production operations to substantially reduce risk and
improve the economics of all partners. For more information, see Bion's
