                                     PART I

    Item 1. Business

    (a) General Development of Business

        Thermo Fibertek Inc. (the Company or the Registrant) designs and
    manufactures processing machinery, accessories, and water-management
    systems for the paper and paper recycling industries. The Company's
    principal products include custom-engineered systems and equipment for
    the preparation of wastepaper for conversion into recycled paper;
    accessory equipment and related consumables important to the efficient
    operation of papermaking machines; and water-management systems essential
    for draining, purifying, and recycling process water. 

        The Company's predecessors have been in operation for more than 100
    years, and the Company has a large, stable customer base that includes
    most papermakers worldwide. The Company seeks to expand its business
    through the introduction of new products and technologies to these
    customers. The Company currently manufactures its products in several
    countries in Europe and North America, and licenses certain of its
    products for manufacture in South America and the Pacific Rim.

        In May 1997, the Company acquired a majority of the assets, subject
    to certain liabilities, of the stock-preparation business of Black
    Clawson Company and affiliates. In August 1997, the Company acquired the
    remaining assets of the stock-preparation business of Black Clawson
    Company and affiliates. This business has been renamed Thermo Black
    Clawson. The aggregate purchase price was approximately $103.4 million in
    cash. Thermo Black Clawson is a leading supplier of recycling equipment
    used in processing fiber for the production of "brown paper," such as
    that used in the manufacture of corrugated boxes.

        Pursuant to a promissory note, the Company borrowed $110.0 million
    from Thermo Electron Corporation to finance the acquisition of Thermo
    Black Clawson. The note was repaid in July 1997 with the net proceeds
    from the sale of $153.0 million principal amount of 4 1/2% subordinated
    convertible debentures due 2004.

        In September 1996, the Company's Thermo Fibergen Inc. subsidiary sold
    4,715,000 units, each unit consisting of one share of Thermo Fibergen
    common stock and one redemption right, in an initial public offering at
    $12.75 per unit for net proceeds of $55.8 million. The common stock and
    redemption rights began trading separately on December 13, 1996. Holders
    of a redemption right have the option to require Thermo Fibergen to
    redeem one share of Thermo Fibergen common stock at $12.75 per share in
    September 2000 or 2001. The redemption rights are guaranteed, on a
    subordinated basis, by Thermo Electron. The Company has agreed to
    reimburse Thermo Electron in the event Thermo Electron is required to
    make a payment under the guarantee. 

                                        2PAGE

        As of January 3, 1998, the Company owned 10,419,950 shares of Thermo
    Fibergen common stock, representing 71% of such outstanding common stock.
    During 1997*, the Company purchased 419,950 shares of Thermo Fibergen
    common stock for $3.8 million.

        The Company is a majority-owned subsidiary of Thermo Electron. As of
    January 3, 1998, Thermo Electron owned 55,150,063 shares of the Company's
    common stock, representing 90% of such outstanding common stock. In
    addition to the Company's products, Thermo Electron provides analytical
    and monitoring instruments; biomedical products including heart-assist
    devices, respiratory-care equipment, and mammography systems;
    alternative-energy systems; industrial process equipment; and other
    specialized products. Thermo Electron also provides industrial
    outsourcing, particularly in environmental-liability management,
    laboratory analysis, and metallurgical processing; and conducts
    advanced-technology research and development. During 1997, Thermo
    Electron purchased 1,779,400 shares of the Company's common stock in the
    open market at a total cost of $16.3 million.

    (b) Financial Information About Industry Segments

        The Company is engaged in one business segment: the design and
    manufacture of equipment, accessory products, and water-management
    systems for the paper and paper recycling industries.

    (c) Description of Business

        (i) Principal Products and Services

    Recycling

        The Company develops, designs, and manufactures custom-engineered
    systems that remove debris, impurities, and ink from wastepaper, and
    process it into a fiber mix used to produce either white or brown grades
    of recycled paper. The Company offers more than 20 products related to 


    * References to 1997, 1996, and 1995 herein are for the fiscal years
      ended January 3, 1998, December 28, 1996, and December 30, 1995,
      respectively.

                                        3PAGE

    all aspects of the recycling process. Some of the systems include:

        Pulping and Trash Removal Systems, including specialized high- and
    low-consistency pulpers that blend wastepaper with water and certain
    chemicals to form pulp without contaminant breakdown, thus increasing the
    efficiency of debris removal; and poires (scavengers) that remove large
    debris.

        Cleaning and Screening Systems, including high-density screens and
    cleaners to remove metals and sand from the pulp mixture, fine screens to
    filter microscopic particles of glue and plastic from the pulp mixture,
    and the patented Gyroclean(R) system to remove "stickies" and the
    lightest plastics from the pulp.

        De-inking Systems, including the patented MacCell that uses the
    latest generation of Autoclean injectors to produce small air bubbles in
    the bottom of the pulp slurry. The ink bonds to the air bubbles and rises
    to the surface, where it is removed through a unique propellant system.
    The efficiency of this unit and the reduced floor space required for
    equivalent ink removal make the MacCell one of the Company's most
    important products within a de-inking system.

        Reject-handling and Water-treatment Systems, including gravity type
    strainers and in-line filtration, developed by the Company's Engineered
    Systems Division (AES), as well as compactors and sand separators
    designed to recapture "good" fiber rejected with debris in the primary
    process line.

        Thermo Fibergen's GranTek subsidiary employs patented technology to
    produce absorbing granules from papermaking sludge. These granules,
    marketed under the trade name Biodac, are principally used as a carrier
    to deliver chemicals for agricultural, professional turf, home lawn and
    garden, and mosquito-control applications.

        Revenues from the Company's recycling business were $93.6 million,
    $56.2 million, and $77.0 million in 1997, 1996, and 1995, respectively.

    Accessories

        The Company designs, develops, and manufactures a wide range of
    accessories that continuously clean the rolls of a papermaking machine,
    remove the sheet (web) from the roll, automatically cut the web during
    sheet breaks, and remove curl from the sheet. These functions are
    critical for paper manufacturers because they help manufacturers avoid
    potential catastrophic damage to the papermaking equipment while reducing
    expensive machine downtime and improving paper quality. Accessories
    include:

        Doctors and related equipment, that shed the sheet from the roll
    during sheet breaks and start-ups and keep rolls clean by removing stock
    accumulations, water rings, fuzz, pitch, and filler buildup.

        Profiling Systems, that help ensure a uniform gloss on the web and
    control moisture and curl within the sheet.

                                        4PAGE

        Revenues from the Company's accessories business were $83.0 million,
    $82.2 million, and $73.9 million in 1997, 1996, and 1995, respectively.

    Water-management

        The Company designs, develops, and manufactures equipment used to
    drain water from the pulp slurry, form the sheet web, and reuse the
    process water. These systems include:

        Formation Tables, consisting of free-draining elements and vacuum
    augmented elements to control the amount of water removed from the pulp
    slurry to form the paper web.

        Showers and Felt-conditioning Systems, used to clean and condition
    the fabrics and felts which in turn are used to transport the paper web
    through various stages of the papermaking machine.

        Water-filtration Systems, consisting of pressure, gravity, and vacuum
    assisted filters and strainers used to remove extraneous contaminants
    from the process water before reuse and to recover reusable fiber for
    recycling back into the pulp slurry.

        Revenues from the Company's water-management business were $44.0
    million, $40.0 million, and $40.8 million in 1997, 1996, and 1995,
    respectively.

    Other

        The Company also manufactures and markets dryers and pollution-
    control equipment for the printing, papermaking, and converting
    industries. The Company's dryers transfer heat efficiently from the dryer
    to the paper web resulting in significant energy savings and improved
    paper and printing quality. The Company's thermal incinerators reduce
    volatile organic compounds (VOCs) that are produced when solvents
    contained in the printed or coated material evaporate. The Company's
    Thermo Black Clawson subsidiary also manufactures and markets the
    Chemi-Washer (R), a horizontal belt washer used in the virgin pulping
    process. The Chemi-Washer consumes less energy than other commercial
    washing systems and significantly decreases the amount of water used and
    effluent produced.

        (ii) and (xi) New Products; Research and Development

        The Company believes that it has a reputation as a technological
    innovator in the market niches it serves, although rapid technological
    obsolescence is not characteristic of the Company's business. The
    Company, which maintains active programs for the development of new
    products using both new and existing technologies, has technology centers
    in Europe and the U.S. dedicated to specific research projects and
    markets.

        For recycling equipment, the Company maintains a stock-preparation
    pilot laboratory adjacent to the manufacturing facility at its E. & M.
    Lamort, S.A. (Lamort) subsidiary and one at Thermo Black Clawson's

                                        5PAGE

    Middletown, Ohio, facility, both of which contain all equipment necessary
    to replicate a commercial stock-preparation system. A customer's
    wastepaper can be tested to determine the exact system configuration that
    would be recommended for its future facility. The testing laboratories
    are also used to evaluate prototype equipment, enabling research teams to
    quickly and thoroughly evaluate new designs. In addition, the Company
    works closely with its customers in the development of products,
    typically field testing new products on the customers' papermaking
    machines. In the U.S., one facility houses an operation for continued
    development of accessory products, while another is devoted to
    development of new water-management products. 

        In 1996, Thermo Fibergen constructed a mobile pilot plant that it
    uses to demonstrate its fiber-recovery process and test the sludge
    streams of mills in the United States and Canada. In 1997, Thermo
    Fibergen continued research and development efforts relating to its
    fiber-recovery systems. In addition, GranTek's processing center in Green
    Bay, Wisconsin, contains a pilot plant that it uses to develop
    sludge-based products and processes employed at its main facility. In
    1997, GranTek successfully completed commercial introduction of a new
    row-crop granule in the South African market that it intends to introduce
    in the U.S. market during 1998. GranTek also introduced a granule for
    oil- and grease-absorption on a limited basis and completed development
    of two formulations of cat box filler product, which GranTek expects to
    begin marketing in 1998.

        The Company seeks to develop a broad range of equipment for all
    facets of the markets it serves. Over the next several years the Company
    expects to focus its research and development efforts on the advancement
    of paper recycling equipment to further improve the quality of recycled
    paper.

        Research and development expenses for the Company were $6.8 million,
    $5.5 million, and $4.1 million in 1997, 1996, and 1995, respectively.

        (iii) Raw Materials

        Raw materials, components, and supplies for all of the Company's
    significant products are available either from a number of different
    suppliers or from alternative sources that could be developed without a
    material adverse effect on the Company's business. To date, the Company
    has experienced no difficulties in obtaining these materials.

        (iv) Patents, Licenses, and Trademarks

        The Company protects its intellectual property rights by applying for
    and obtaining patents when appropriate. The Company also relies on
    technical know-how, trade secrets, and trademarks to maintain its
    competitive position. The Company has numerous U.S. and foreign patents,
    expiring on various dates ranging from 1998 to 2014.

                                        6PAGE

        Third parties have certain rights in two of the Company's patents
    that were jointly developed with such parties. The initial development of
    the Company's Gyroclean equipment was provided by Centre Technique du
    Papier (CTP), to which the Company provided further design refinement and
    applications expertise. The Company currently holds an exclusive
    long-term, worldwide license for a patent on technology that CTP
    developed. The Company and CTP have joint ownership of a second patent on
    technology that was jointly developed.

        The Company maintains a worldwide network of licensees and cross-
    licensees of products with other companies servicing the pulp,
    papermaking, converting, and paper recycling industries. The Company
    holds an exclusive worldwide license for its de-inking cells under an
    agreement that extends until 2007. The Company also has license
    arrangements with several companies with regard to its dryers, pollution-
    control equipment, and accessory equipment. Thermo Fibergen has granted
    two companies nonexclusive licenses under two of its patents to sell
    cellulose-based granules produced at an existing site for sale in the
    oil- and grease-absorption and cat box filler markets.

        (v) Seasonal Influences

        There are no material seasonal influences on the Company's sales of
    products and services.

        (vi) Working Capital Requirements

        There are no special inventory requirements or credit terms extended
    to customers that would have a material adverse effect on the Company's
    working capital.

        (vii) Dependency on a Single Customer

        No single customer accounted for more than 10% of the Company's
    revenues in any of the past three years.

        (viii) Backlog

        The Company's backlog of firm orders as of January 3, 1998, and
    December 28, 1996, was $60.0 million and $37.1 million, respectively. The
    Company anticipates that substantially all of the backlog at January 3,
    1998, will be shipped or completed during the next twelve months. Certain
    of these orders may be canceled by the customer upon payment of a
    cancellation fee. The Company's backlog of firm orders increased
    principally due to the inclusion of $22.8 million of backlog at Thermo
    Black Clawson, acquired May 1997.

        (ix) Government Contracts

        Not applicable.

                                        7PAGE

        (x) Competition

        The Company faces significant competition in each of its principal
    markets. The Company competes principally on the basis of quality,
    service, technical expertise, product innovation, and price. The Company
    believes that the reputation it has established over more than 100 years
    for quality products and in-depth process knowledge provides it with a
    competitive advantage. In addition, a significant portion of the
    Company's business is generated from its existing customer base. To
    maintain this base, the Company has emphasized service and a
    problem-solving relationship with its customers.

        The Company is a leading supplier of recycling equipment for the
    preparation of wastepaper to be used in the production of recycled paper.
    There are several major competitors that supply various pieces of
    equipment for this process. The Company's principal competitors on a
    worldwide basis are Voith Sulzer Papiertechnik, Beloit Corporation,
    Ahlstrom Machine Company, Kvaerner Pulping Technologies, Sunds Defibrator
    Inc., and Maschinenfabrik Andritz AG. Various competitors tend to
    specialize in segments within the white and brown paper markets. The
    Company competes in the recycling-equipment marketplace primarily on the
    basis of systems knowledge, product innovation, and price.

        The Company is a leading supplier of specialty accessory equipment
    for papermaking machines. Because of the high capital costs of
    papermaking machines and the role of the Company's accessories in
    maintaining the efficiency of these machines, the Company generally
    competes in this market on the basis of service, technical expertise, and
    performance.

        The Company is a leading supplier of water-management systems.
    Various competitors exist in the formation table, conditioning and
    cleaning systems, and filtration systems markets. JWI Group/Johnson Foils
    is a major supplier of formation tables while a variety of smaller
    companies compete within the cleaning and conditioning and filtration
    markets. In each of these areas, process knowledge, application
    experience, product quality, service, and price are key factors.

        (xii) Environmental Protection Regulations

        The Company believes that compliance by the Company with federal,
    state, and local environmental protection regulations will not have a
    material adverse effect on its results of operations, financial
    condition, or competitive position.

        (xiii) Number of Employees

        As of January 3, 1998, the Company employed approximately 1,404
    people. Approximately 78 employees at the Company's Kaukauna, Wisconsin,
    operation are represented by a labor union under a collective bargaining
    agreement expiring May 31, 1998. Approximately 30 employees at the
    Company's Pointe Claire, Quebec, Canada, operation are represented by a
    labor union under a collective bargaining agreement expiring August 31,
    1999. Approximately 18 employees at the Company's Middletown, Ohio,

                    Report of Independent Public Accountants

    To the Shareholders and Board of Directors of Thermo Fibertek Inc.:

        We have audited, in accordance with generally accepted auditing
    standards, the consolidated financial statements included in Thermo
    Fibertek Inc.'s Annual Report to Shareholders incorporated by reference
    in this Form 10-K, and have issued our report thereon dated February 9,
    1998. Our audits were made for the purpose of forming an opinion on those
    statements taken as a whole. The schedule listed in Item 14 on page 13 is
    the responsibility of the Company's management and is presented for
    purposes of complying with the Securities and Exchange Commission's rules
    and is not part of the basic consolidated financial statements. This
    schedule has been subjected to the auditing procedures applied in the
    audits of the basic consolidated financial statements and, in our
    opinion, fairly states in all material respects the consolidated
    financial data required to be set forth therein in relation to the basic
    consolidated financial statements taken as a whole.
