EXHIBIT 10.25
                              THERMO FIBERTEK INC.

                 THERMO FIBERGEN NONQUALIFIED STOCK OPTION PLAN

        1.   Purpose

             This Nonqualified Stock Option Plan (the "Plan") is intended
        to encourage ownership of Common Stock, $0.01 par value (the
        "Common Stock"), of Thermo Fibergen Inc. ("Subsidiary"), a
        subsidiary of Thermo Fibertek Inc. (the "Company"), by persons
        selected by the Board of Directors (or a committee thereof) in
        its sole discretion, including directors, executive officers, key
        employees and consultants of the Company and its subsidiaries,
        and to provide additional incentive for them to promote the
        success of the business of the Company and Subsidiary.  The Plan
        is intended to be a nonstatutory stock option plan.

        2.   Effective Date of the Plan

             The Plan shall become effective when adopted by the Board of
        Directors of the Company.

        3.   Stock Subject to Plan

             At no time shall the number of shares of the Common Stock
        then outstanding which are attributable to the exercise of
        options granted under the Plan plus the number of shares then
        issuable upon the exercise of outstanding options granted under
        the Plan exceed 200,000 shares, subject however,  to the
        provisions of paragraph 11 of the Plan.  Shares to be issued upon
        the exercise of options granted under the Plan shall be shares of
        Subsidiary beneficially owned by the Company.  If any option
        expires or terminates for any reason without having been
        exercised in full, the unpurchased shares subject thereto shall
        again be available for options thereafter to be granted.

        4.   Administration

             The Plan shall be administered by a committee (the
        "Committee") composed of the members of the Board of Directors of
        the Company, no member of which shall act upon any matter
        exclusively affecting any option granted or to be granted to
        himself or herself under the Plan.  Subject to the provisions of
        the Plan, the Committee shall have complete authority, in its
        discretion, to make the following determinations with respect to
        each option to be granted by the Company:  (a) the person to
        receive the option (the "Optionee"); (b) the time of granting the
        option; (c) the number of shares subject thereto; (d) the option
        price; (e) the option period; and (f) the terms of the option and
        form of option agreement (which need not be identical, but which
        shall conform to the applicable terms and conditions of the Plan
        and contain such other provisions as the Board of Directors deems
        advisable and not inconsistent with the Plan).  In making such
PAGE

        determinations, the Committee may take into account the nature of
        the services rendered by the Optionees, their present and
        potential contributions to the success of the Company and/or one
        or more of its subsidiaries, and such other factors as the
        Committee in its discretion shall deem relevant.  Subject to the
        provisions of the Plan, the Committee shall also have complete
        authority to interpret the Plan, to prescribe, amend, and rescind
        rules and regulations relating to it, to determine the terms and
        provisions of the respective option agreements (which need not be
        identical), and to make all other determinations necessary or
        advisable for the administration of the Plan.  The Committee's
        determinations on the matters referred to in this paragraph 4
        shall be conclusive.

        5.   Eligibility

             An option may be granted to any person selected by the
        Committee in its sole discretion.

        6.   Time of Granting Options

             The granting of an option shall take place at the time
        specified by the Committee.  Only if expressly so provided by the
        Committee shall the granting of an option be regarded as taking
        place at the time when a written option agreement shall have been
        duly executed and delivered by or on behalf of the Company and
        the Optionee to whom such option shall be granted.  The agreement
        shall provide, among other things, that it does not confer upon
        an Optionee any right to continue in the employ of the Company
        and/or one or more of its subsidiaries or to continue as a
        director or consultant of the Company, and that it does not
        interfere in any way with the right of the Company or any such
        subsidiary to terminate the employment of the Optionee at any
        time if the Optionee is an employee, to remove the Optionee as a
        director of the Company if the Optionee is a director, or to
        terminate the services of the Optionee if the Optionee is a
        consultant.

        7.   Option Period

             An option may become exercisable immediately or in such
        installments, cumulative or noncumulative, as the Committee may
        determine.  

        8.   Exercise of Option

             An option may be exercised in accordance with its terms by
        written notice of intent to exercise the option, specifying the
        number of shares of stock with respect to which the option is
        then being exercised.  The notice shall be accompanied by payment
        in the form of cash or shares of Subsidiary Common Stock (the
        "Tendered Shares") with a then current market value equal to the
        option price of the shares to be purchased; provided, however,
        that such Tendered Shares shall have been acquired by the
                                    2PAGE

        Optionee more than six months prior to the date of exercise,
        unless such requirement is waived in writing by the Company.
        Against such payment the Company shall deliver or cause to be
        delivered to the Optionee a certificate for the number of shares
        then being purchased, registered in the name of the Optionee or
        other person exercising the option.  If any law or applicable
        regulation of the Securities and Exchange Commission or other
        body having jurisdiction in the premises shall require the
        Company, Subsidiary or the Optionee to take any action in
        connection with shares being purchased upon exercise of the
        option, exercise of the option and delivery of the certificate or
        certificates for such shares shall be postponed until completion
        of the necessary action, which shall be taken at the Company's
        expense.

        9.   Transferability

             Options shall not be transferable, otherwise than by will or
        the laws of descent and distribution, except as may be authorized
        by the Committee, in its sole discretion. The Committee may, in
        its discretion, determine the extent to which options granted to
        an Optionee shall be transferable, and such provisions permitting
        transfer shall be set forth in the written option agreement
        executed and delivered by or on behalf of the Company and the
        Optionee.

        10.  Vesting, Restrictions and Termination of Options

             The Committee, in its sole discretion, may determine the
        manner in which options shall vest, the rights of the Company to
        repurchase the shares issued upon the exercise of any option and
        the manner in which such rights shall lapse, and the terms upon
        which any option granted shall terminate.  The Board of Directors
        shall have the right to accelerate the date of exercise of any
        installment or to accelerate the lapse of the Company's
        repurchase rights.  All of such terms shall be specified in a
        written option agreement executed and delivered by or on behalf
        of the Company and the Optionee to whom such option shall be
        granted.

        11.  Adjustment of Number of Shares

             Each stock option agreement shall provide that in the event
        of any stock dividend payable in the Common Stock or any split-up
        or contraction in the number of shares of the Common Stock
        occurring after the date of the agreement and prior to the
        exercise in full of the option, the number of shares for which
        the option may thereafter be exercised shall be proportionately
        adjusted and the price to be paid for each share subject to the
        option shall be proportionately adjusted.  Each such agreement
        shall also provide that in case of any reclassification or change
        of outstanding shares of the Common Stock or in case of any
        consolidation or merger of Subsidiary with or into another
        company or in case of any sale or conveyance to another company
                                   3PAGE

        or entity of the property of Subsidiary as a whole or
        substantially as a whole, the Optionee shall, upon exercise of
        the option, be entitled to receive shares of stock or other
        securities in its place equivalent in kind and value to those
        shares which he would have received if he had exercised the
        option in full immediately prior to such reclassification,
        change, consolidation, merger, sale or conveyance and had
        continued to hold the shares subject to the option (together with
        all other shares, stock and securities thereafter issued in
        respect thereof) to the time of the exercise of the option;
        provided, that if any recapitalization is to be effected through
        an increase in the par value of the Common Stock without an
        increase in the number of authorized shares and such new par
        value will exceed the option price under such agreement, the
        Company shall notify the Optionee of such proposed
        recapitalization, and the Optionee shall then have the right,
        exercisable at any time prior to such recapitalization becoming
        effective, to purchase all of the shares subject to the option
        which he has not theretofore purchased (anything in such
        agreement to the contrary notwithstanding), but if the Optionee
        fails to exercise such right before such recapitalization becomes
        effective, the option price under such agreement shall be
        appropriately adjusted.  Each such agreement shall further
        provide that upon dissolution or liquidation of Subsidiary, the
        option shall terminate, but the Optionee (if at the time an
        employee or director of the Company and/or any one or more of its
        subsidiaries) shall have the right, immediately prior to such
        dissolution or liquidation, to exercise the option to the full
        extent not theretofore exercised; that no adjustment provided for
        above shall apply to any share with respect to which the option
        has been exercised prior to the effective date of such
        adjustment; and that no fraction of a share or fractional shares
        shall be purchasable or deliverable under such agreement, but in
        the event any adjustment thereunder of the number of shares
        covered by the option shall cause such number to include a
        fraction of a share, such fraction shall be adjusted to the
        nearest smaller whole number of shares.  In the event of changes
        in the outstanding Common Stock by reason of any stock dividend,
        split-up, contraction, reclassification, or change of outstanding
        shares of the Common Stock of the nature contemplated by this
        paragraph 11, the number of shares of Common Stock available for
        the purpose of the Plan as stated in paragraph 3 hereof shall be
        correspondingly adjusted by the Committee.

        12.  Limitation of Rights in Option Stock

             The Optionees shall have no rights as stockholders in
        respect of shares as to which their options shall not have been
        exercised, certificates issued and delivered and payment as
        herein provided made in full, and shall have no rights with
        respect to such shares not expressly conferred by this Plan.
                                  4PAGE

        13.  Stock Reserved

             The Company shall at all times during the term of the
        options reserve and keep available such number of shares of the
        Common Stock as will be sufficient to satisfy the requirements of
        this Plan and shall pay all other fees and expenses necessarily
        incurred by the Company in connection therewith.

        14.  Securities Laws Restrictions

             Each Optionee exercising an option, at the request of the
        Company, will be required to give a representation in form
        satisfactory to counsel for the Company that he will not
        transfer, sell or otherwise dispose of the shares received upon
        exercise of the option at any time purchased by him, upon
        exercise of any portion of the option, in a manner which would
        violate the Securities Act of 1933, as amended, and the
        regulations of the Securities and Exchange Commission thereunder
        and the Company may, if required or at its discretion, make a
        notation on any certificates issued upon exercise of options to
        the effect that such certificate may not be transferred except
        after receipt by the Company of an opinion of counsel
        satisfactory to it to the effect that such transfer will not
        violate such Act and such regulations.

        15.  Tax Withholding

             The Company shall have the right to deduct from payments of
        any kind otherwise due to an Optionee any federal, state or local
        taxes of any kind required by law to be withheld with respect to
        any shares issued upon exercise of options under the Plan (the
        "withholding requirements").  The Committee will have the right
        to require that the Optionee or other appropriate person remit to
        the Company an amount sufficient to satisfy the withholding
        requirements, or make other arrangements satisfactory to the
        Committee with regard to such requirements, prior to the delivery
        of any Common Stock pursuant to exercise of an option.  If and to
        the extent that such withholding is required, the Committee may
        permit the Optionee or such other person to elect at such time
        and in such manner as the Committee provides to have the Company
        hold back from the shares to be delivered, or to deliver to the
        Company, Common Stock having a value calculated to satisfy the
        withholding requirements.

        16.  Termination and Amendment of Plan

             The Board of Directors may at any time, and from time to
        time, modify or amend the Plan in any respect.

             Notwithstanding any other provisions hereof, the Plan shall
        terminate on December 31, 2006 and no options shall be granted
        hereunder thereafter.
