                    INFORMATION TO BE INCLUDED IN THE REPORT

                                 Amendment No. 1

         The  undersigned  registrant  hereby amends the following  items of its
Current Report on Form 8-K dated February 29, 1996.

Item 2.           Acquisition or Disposition of Assets.

         This  section sets forth the  complete  text of Item 2 as amended.  The
undersigned  registrant has added information in the second paragraph  regarding
the OWT Notes (as  defined  below)  and has  revised  information  in the fourth
paragraph as to the positions held by John Pacey.

         EMCON (the  "Company"  or "EMCON")  has  completed a  transaction  with
Organic  Waste  Technologies,  Inc.  ("OWT"),  the  holders of OWT's  common and
preferred stock ("OWT Stock") and the holders of options to acquire common stock
of OWT (the "OWT Options"; collectively, the OWT Stock and the OWT Options being
`referred  to  herein  as the "OWT  Securities"  and the  holders  thereof,  the
"Sellers").  There  were 34  Sellers  in the  Acquisition.  As a  result  of the
transaction  (the  "Acquisition"),  OWT has become a wholly-owned  subsidiary of
EMCON.

         The  Acquisition,   which  was  announced  on  January  30,  1996,  was
consummated on February 29, 1996. To complete the Acquisition,  OWT issued notes
to certain Sellers who are part of OWT's  management,  in an aggregate amount of
$1,824,649,  minus such Sellers' pro rata shares of certain fees and expenses in
connection with the Acquisition (the "OWT Notes"), in exchange for such Sellers'
OWT  Securities;  EMCON paid an  aggregate of  $13,754,351  in cash to the other
Sellers in exchange  for such  Sellers' OWT  Securities;  and EMCON paid certain
fees  and  expenses  incurred  by  OWT  and  the  Sellers  with  respect  to the
transaction  (the pro rata share of which was  deducted  from the  consideration
received by each Seller for his, her or its OWT  Securities).  The OWT Notes are
convertible  into common stock of OWT upon an  underwritten  public  offering of
OWT's common stock in an amount in excess of $10 million.  In the event that the
OWT Notes have not been  converted  into shares of OWT common stock they may, at
the  election of the holder,  instead be  converted  into shares of EMCON common
stock for a period of ninety days after November 30, 2000 at a conversion  price
of $6.50 per  share.  The OWT  Securities  acquired  by OWT and the OWT  Options
acquired have been canceled.

         The amount of  consideration  was determined based upon OWT's projected
earnings  and as a result of a  competitive  bidding  process  and arm's  length
negotiations  between  management  teams of both companies with input from their
respective boards of directors.

          The only material relationship between (a) EMCON, its affiliates,  its
directors and officers or any associate of its directors or officers and (b) the
Sellers, is that John Pacey, chairman emeritus of, and an independent consultant
to, EMCON, is a Seller and was, prior to the Acquisition, a director of OWT. Mr.
Pacey will remain a director of OWT after the  Acquisition.  The Acquisition was
partially  financed through a $10 million term loan from The Bank of California,
N.A., with the remainder financed from the Company's working capital.

         A  copy  of  the  press  release  announcing  the  consummation  of the
Acquisition  is  attached  as  Exhibit  99.1,  and  is  incorporated  herein  by
reference.
