Exhibit B

Neither this Warrant nor the shares of Common Stock issuable on exercise of this
Warrant have been  registered  under the  Securities  Act of 1933.  None of such
securities may be transferred in the absence of  registration  under such Act or
an opinion of counsel to the effect that such registration is not required.

1.   THIS   CERTIFIES   THAT  the  Holder  is  entitled  to  purchase  from  IDM
     ENVIRONMENTAL  CORP.,  a New  Jersey  corporation  (hereinafter  called the
     "Company"),  the number of shares of the  Company's  common stock  ("Common
     Stock") set forth above, at an exercise price equal to $3.00,  or, if less,
     the lowest  Conversion  Price at which,  prior to exercise,  any  Purchaser
     shall  have  converted  any Note or any  portion  of any  Note.  The  terms
     "Conversion Price," "Notes" and "Purchaser" have the meanings attributed to
     them in the Subscription  Agreement (as hereinafter defined).  This Warrant
     may be exercised in whole or in part at any time prior to  expiration.  The
     exercise price for each exercise shall be computed  separately,  so that if
     after any given exercise,  a Note is converted at a Conversion  Price lower
     than  $3.00  and lower  than the  exercise  price  relating  to such  first
     exercise,  the exercise price for the later exercise shall be equal to such
     Conversion Price.

2.   All rights granted under this Warrant shall expire on the third anniversary
     of the date of issuance of this Warrant.

3.   Notwithstanding anything to the contrary contained herein, Holder shall not
     have the right to exercise  this  Warrant so long as and to the extent that
     at the time of such exercise,  such exercise would cause the Holder then to
     be the  "beneficial  owner" of five percent  (5%) or more of the  Company's
     then outstanding  Common Stock.  For purposes hereof,  the term "beneficial
     owner"  shall  have the  meaning  ascribed  to it in  Section  13(d) of the
     Securities Exchange Act of 1934. The opinion of legal counsel to Holder, in
     form and substance  satisfactory to the Company and the Company's  counsel,
     shall prevail in all matters relating to the amount of Holder's  beneficial
     ownership.

4.   In the event the Company  breaches its  obligation  to deliver  irrevocable
     instructions  to its transfer agent as required under Section 14, or timely
     to make any payment  required  under  Section 7 for Common Stock under this
     Warrant upon exercise,  then,  without  limiting  Holder's other rights and
     remedies,  the Company shall forthwith pay to the Holder an amount accruing
     at the rate of $1,000 per day for each day of such  breach for each  20,000
     shares of common stock subject to this Warrant,  with pro rata payments for
     shares in an amount less than 20,000.

5.   This Warrant and the Common Stock issuable on exercise of this Warrant (the
     "Underlying  Shares") may be transferred,  sold,  assigned or hypothecated,
     only if  registered by the Company  under the  Securities  Act of 1933 (the
     "Act") or if the Company has received from counsel to the Company a written
     opinion to the effect that  registration  of the Warrant or the  Underlying
     Shares is not necessary in connection with such transfer,  sale, assignment
     or   hypothecation.   The  Warrant  and  the  Underlying  Shares  shall  be
     appropriately  legended  to  reflect  this  restriction  and stop  transfer
     instructions shall apply. The Holder shall through its counsel provide such
     information as is reasonably necessary in connection with such opinion.

6.   The holder of this warrant is entitled to certain registration rights under
     an Agreement  dated of even date herewith (the  "Subscription  Agreement").
     Upon  each  permitted  transfer  of this  Warrant  after  the  registration
     statement has been declared effective, the Company will within two business
     days after receipt of notice thereof supplement the registration  statement
     to reflect the name of the transferee as a selling shareholder thereunder.

7.   The  Company  covenants  to call a special  meeting of  shareholders  on or
     before November 15, 1997 to approve the issuance of shares on conversion of
     the  Notes  and  Warrants  issued  to the  Purchasers  (as  defined  in the
     Subscription  Agreement).  Joel  Freedman and Frank Falco have on this date
     agreed to vote in favor of such  approval and the Board of Directors of the
     Company will recommend that the  shareholders  of the Company vote in favor
     of such  approval.  Until such approval is obtained,  the maximum number of
     shares which will be issued on  conversion of the Notes and exercise of the
     Warrants is 1,997,130, issuable on a first converted-first exercised basis.
     Should such approval not be obtained by November 15, 1997,  then until such
     approval is  obtained,  the  Company  shall on demand by Holder made at any
     time or times redeem any portion of the Warrant  designated  for redemption
     (the "Redeemed  Portion") at a redemption price equal to the pre-tax profit
     Holder  would have earned had Holder,  at the close of business on the date
     of  its  demand  for  redemption,   exercised  the  Redeemed   Portion  and
     simultaneously  sold the shares  received  on such  exercise at the closing
     NASDAQ  sales  price on such date.  The  redemption  price shall be payable
     within five  business days after demand for  redemption is made,  and shall
     accrue interest payable on demand at 11% per annum.

8.   Any permitted assignment of this Warrant shall be effected by the Holder by
     (i) executing the form of assignment at the end hereof,  (ii)  surrendering
     the Warrant for  cancellation at the office of the Company,  accompanied by
     the opinion of counsel to the Company  referred to above;  and (iii) unless
     in connection  with an effective  registration  statement  which covers the
     sale of this Warrant and or the shares underlying the Warrant,  delivery to
     the Company of a statement by the transferee  (in a form  acceptable to the
     Company and its counsel) that such Warrant is being  acquired by the Holder
     for investment and not with a view to its distribution or resale; whereupon
     the  Company  shall  issue,  in the name or names  specified  by the Holder
     (including the Holder) new Warrants representing in the aggregate rights to
     purchase  the same  number of Shares as are  purchasable  under the Warrant
     surrendered.  Such Warrants shall be exercisable  immediately upon any such
     assignment of the number of Warrants assigned.  The transferor will pay all
     relevant transfer taxes. Replacement warrants shall bear the same legend as
     is borne by this Warrant.

9.   The term  "Holder"  should  be  deemed  to  include  any  permitted  record
     transferee of this Warrant.

10.  The Company  covenants and agrees that all shares of Common Stock which may
     be issued upon exercise  hereof will,  upon  issuance,  be duly and validly
     issued, fully paid and non-assessable and no personal liability will attach
     to the holder  thereof.  The Company  further  covenants  and agrees  that,
     during the periods within which this Warrant may be exercised,  the Company
     will at all times  have  authorized  and  reserved a  sufficient  number of
     shares of Common Stock for issuance  upon  exercise of this Warrant and all
     other Warrants.

11.  This  Warrant  shall not entitle  the Holder to any voting  rights or other
     rights as a stockholder of the Company.

12.  In the event  that as a result of  reorganization,  merger,  consolidation,
     liquidation,  recapitalization, stock split, combination of shares or stock
     dividends payable with respect to such Common Stock, the outstanding shares
     of Common  Stock of the Company are at any time  increased  or decreased or
     changed into or exchanged for a different  number or kind of share or other
     security  of  the  Company  or of  another  corporation,  then  appropriate
     adjustments in the number and kind of such  securities then subject to this
     Warrant shall be made  effective as of the date of such  occurrence so that
     the position of the Holder upon  exercise will be the same as it would have
     been had it owned  immediately  prior to the  occurrence of such events the
     Common  Stock  subject  to this  Warrant.  Such  adjustment  shall  be made
     successively  whenever  any event  listed above shall occur and the Company
     will notify the Holder of the Warrant of each such adjustment. Any fraction
     of a share resulting from any adjustment  shall be eliminated and the price
     per  share  of the  remaining  shares  subject  to  this  Warrant  adjusted
     accordingly.

13.  The rights  represented by this Warrant may be exercised at any time within
     the period  above  specified by (i)  surrender  of this  Warrant  (with the
     purchase  form  at the  end  hereof  properly  executed)  at the  principal
     executive  office of the  Company  (or such  other  office or agency of the
     Company  as it may  designate  by notice in  writing  to the  Holder at the
     address of the Holder appearing on the books of the Company);  (ii) payment
     to the Company of the exercise price for the number of Shares  specified in
     the  above-mentioned  purchase form together with applicable stock transfer
     taxes,   if  any;  and  (iii)  unless  in  connection   with  an  effective
     registration  statement which covers the sale of the shares  underlying the
     Warrant,  the  delivery to the  Company of a statement  by the Holder (in a
     form  acceptable to the Company and its counsel) that such Shares are being
     acquired  by the  Holder  for  investment  and  not  with a view  to  their
     distribution or resale.

14.  Within two  business  days  following  each  receipt by the  Company of the
     documents  required to exercise all any part of this Warrant as provided in
     Section 13, the  Company  shall  deliver  irrevocable  instructions  to its
     transfer  agent  (with a copy to  Holder)  to issue on an  expedited  basis
     certificates  evidencing  the  shares of common  stock so  purchased.  Such
     certificates shall bear appropriate  restrictive legends in accordance with
     applicable  securities  laws, but shall be unrestricted and bear no legends
     once  the  registration  statement  referred  to above  has  been  declared
     effective.

15.  This Warrant shall be governed by and construed in accordance with the laws
     of the State of New Jersey.  The  federal  and state  courts in the city of
     Newark,  New Jersey shall have exclusive  jurisdiction over this instrument
     and the  enforcement  thereof.  Service of process shall be effective if by
     certified mail, return receipt  requested.  All notices shall be in writing
     and shall be deemed given upon receipt by the party to whom addressed. This
     instrument shall be enforceable by decrees of specific performances well as
     other remedies.

     IN WITNESS WHEREOF,  IDM Environmental  Corp. has caused this Warrant to be
signed by its duly authorized officers under Its corporate seal, and to be dated
as of the date set forth above.
