EXPLANATORY NOTE

     This amended Schedule 13D, dated January 15, 2002, relates to the
beneficial ownership of D2 Co., LLC and Atlantic Partners LLC, of which David
Mitchell is the sole member, of the Common Stock of Bion Environmental
Technologies, Inc.

     In January 15, 2002, as a result of significant transactions in which
Bion Technologies, Inc. was involved, certain Convertible Notes held by or for
the benefit of the Reporting Persons were automatically converted into common
stock, and the terms of certain warrants were changed.  This Amendment
reflects these changes, and also updates other information concerning the
beneficial ownership of the Reporting Persons.

ITEM 1.  SECURITY AND ISSUER

     The title of the class of equity securities to which this statement
relates is Common Stock, no par value per share (the "Common Stock"), of Bion
Environmental Technologies, Inc., a Colorado corporation, which has its
principal executive offices at 18 East 50th Street, 10th Floor, New York, New
York 10022 (the "Issuer" or "Bion").

ITEM 2.  IDENTITY AND BACKGROUND

     The information set forth herein is given with respect to (1) D2 Co., LLC
("D2"), a Delaware limited liability company, (2) Atlantic Partners LLC
("Atlantic"), a Delaware limited liability company, and (3) David Mitchell, a
U.S. citizen, the sole member of D2 and Atlantic.  D2 and Atlantic are engaged
in the investment in and management of other companies.  David Mitchell is
currently Chairman, President, CEO and a Director of Bion.  During the last
five years, none of these persons or any executive officer, director or
controlling person of such person, has been convicted in a criminal proceeding
(excluding traffic violations or similar misdemeanors).  In addition, during
the last five years, none of these persons, or any executive officer, director
or controlling person of such person was a party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of
such proceeding was or is subject to a judgment, decree or final order
enjoining future violations of, or prohibiting or mandating activities subject
to, Federal or state securities laws or finding any violation with respect to
such laws.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     The funds used by D2 and Atlantic to purchase the notes and warrants
referred to herein consisted of the capital contributions of David Mitchell
and general working capital.  In addition, some of the notes were received for
management services performed.

----------------------------------------------------------------------------


ITEM 4.  PURPOSE OF TRANSACTION

     As a result of transactions in which Bion was involved on January 15,
2002, notes held by D2 and a trust for D2 were converted into the Issuer's
Common Stock.  In addition, the terms of warrants held by D2 and Atlantic were
changed.  The conversions and changes were in compliance with the terms of the
related notes and warrants.

     The notes and warrants had been acquired by the Reporting Persons for the
purpose of obtaining a significant investment in the Issuer.  The notes were
acquired pursuant to the terms of a management agreement between D2 and Bion.
Under the terms of the management agreement, D2 obtained the right to name
three designees to the Board of Directors of Bion, and certain other rights.

     Giving effect to the conversion and changes, D2, Atlantic and David
Mitchell now have beneficial ownership of shares of Bion's Common Stock as set
forth in Item 5 hereof.  D2 will also receive additional shares of Bion's
Common Stock pursuant to the terms of a management agreement with Bion for
services to be provided by D2.  Under this agreement, D2 receives shares of
Common Stock for management services equal in value to $600,000 for the
calendar year 2002 and $750,000 for the calendar year 2003.
