PAGE PROSPECTUS 12,644,628 Shares THERMO FIBERTEK INC. Common Stock This Prospectus relates to the resale of 12,644,628 shares (the "Shares") of Common Stock, par value $.01 per share (the "Common Stock"), of Thermo Fibertek Inc. (the "Company") issuable upon conversion of $153,000,000 principal amount of the Company's outstanding 4-1/2% Convertible Subordinated Debentures due 2004 (the "Debentures"). The Debentures are convertible, at the option of the holder (a "Selling Shareholder"), at a conversion price of $12.10 per share, subject to adjustment for certain events. The Shares may be offered from time to time in transactions on the American Stock Exchange, in negotiated transactions, through the writing of options on the Shares, or a combination of such methods of sale, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. Such transactions may be effected by the sale of the Shares to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the sellers and/or the purchasers of the Shares for whom such broker-dealers may act as agent or to whom they sell as principal, or both (which compensation to a particular broker-dealer might be in excess of customary commissions). The sellers of the Shares and any broker-dealer who acts in connection with the sale of Shares hereunder may be deemed to be "underwriters" as that term is defined in the Securities Act of 1933, as amended (the "Securities Act"), and any commission received by them and profit on any resale of the Shares as principal might be deemed to be underwriting discounts and commissions under the Securities Act. None of the proceeds from the sale of the Shares will be received by the Company. The Company has agreed to bear all expenses (other than underwriting discounts and selling commissions, and fees and expenses of counsel or other advisors to the sellers of the Shares) in connection with the registration and sale of the Shares being registered hereby.

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 80 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. Recycling Equipment. 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 all aspects of the recycling process, including pulping and trash removal systems that convert wastepaper into pulp, thus increasing the efficiency of debris removal; poires, or scavengers, that remove large debris; cleaning and screening systems that remove contaminants such as metals, sand, plastic, glue and "stickies" from the pulp mixture; de-inking systems that remove ink particles from the pulp mixture; and reject-handling and water-treatment systems, including gravity type strainers and in-line filtration systems, as well as compactors and sand separators designed to recapture "good" fiber rejected with debris in the primary process line. Accessories. The Company designs, develops and manufactures a wide range of accessories that continuously clean the rolls of a papermaking machine, remove the sheet, or 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 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; and profiling systems that help ensure a uniform gloss on the web and control moisture and curl within the sheet. Water-management Systems. The Company designs, develops and manufactures equipment used to drain water from the pulp's slurry, form the sheet web and reuse the process water. The systems include formation tables that control the amount of water 4 PAGE 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; and 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. Thermo Fibergen. The Company's majority-owned Thermo Fibergen Inc. subsidiary ("Thermo Fibergen") is currently developing equipment and systems to recover materials from papermaking sludge generated by plants that produce virgin and recycled pulp and paper. Thermo Fibergen's GranTek Inc. subsidiary employs patented technology to produce absorbing granules from papermaking sludge. These granules, marketed under the trade name BIODAC (R), are currently used as a carrier to deliver agricultural chemicals for professional turf, home lawn and garden, agricultural row crop and mosquito-control applications. 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 since its inception for quality products and in-depth process knowledge provides it with a competitive advantage. ACQUISITION OF THE STOCK-PREPARATION BUSINESS OF THE BLACK CLAWSON COMPANY In May 1997, the Company acquired the stock-preparation business, excluding the French subsidiary, of the Black Clawson Company and its affiliates ("Black Clawson"). In August 1997, the Company acquired the stock-preparation business of Black Clawson's French subsidiary. Black Clawson is a leading supplier of recycling equipment used in processing fiber for the manufacture of "brown paper," such as that used to make corrugated boxes and other containers. The purchase price for Black Clawson's stock-preparation business was approximately $108 million in cash. The purchase price is subject to a post-closing adjustment equal to the amount by which the net tangible assets of the business acquired as of the closing date are greater or less than, as the case may be, certain target amounts set forth in the Asset Purchase Agreement dated as of May 22, 1997 between the Company, and certain of its affiliates, and the Black Clawson Company, and certain of its affiliates. To finance the acquisition, the Company borrowed approximately $110 million from Thermo Electron Corporation ("Thermo Electron") at an interest rate equal to the 90-day Commercial Paper Composite Rate plus 25 basis points, set at the beginning of each quarter. The Company repaid all of such 5 PAGE indebtedness with the net proceeds from the sale of the Debentures. Black Clawson designs, engineers, manufactures and distributes paper stock-preparation systems and pulp processing systems, which are used in the recycling of waste paper and paperboard into wholly or partially recycled paper products and in the preparation of virgin pulp and paper. Black Clawson also supplies the customers of its stock-preparation systems with replacement and spare parts. In addition, Black Clawson's extensive research and development capabilities allow it to provide technologically advanced solutions to its customers' needs for pulp processing and stock-preparation systems. Black Clawson can design, engineer and supply substantially all of the components of a pulp processing and stock-preparation system for its customers. Principal Products Black Clawson's stock-preparation equipment uses various methods, including hydrapulper technology, to prepare waste-paper and virgin pulp for recycling and formulation into paper stock. The hydrapulper system processes cellulose fibers by blending wastepaper with water and chemicals to break larger fibers down into individual fibers and fiber bundles, which can then be processed and reformulated into paper products. Other products manufactured by Black Clawson include high density cleaning systems, used to remove metal and sand from paper to be recycled; screening systems, used in processing brown paper stock; pulp washers, used in virgin pulp mills to remove chemicals and cooking residues from the pulp; stock thickeners, used to drain water from paper stock to increase the consistency of the finished product; and dispersers, used to break up ink particles to facilitate their removal from paper being processed. In prior years, approximately one-third of Black Clawson's revenue has come from sales of spare parts and service on the installed base of its equipment. Black Clawson has established a network of five independent repair and service centers which respond to customer requests for repairs or replacements. These centers purchase all required component parts for repairs from Black Clawson and replace or repair units to customer specifications. Sales and Marketing Black Clawson uses a multi-faceted approach to the sale and marketing of its products, combining direct sales to mills, exclusive sales representatives, distribution agreements and licensees. Black Clawson has teams of sales engineers based worldwide, who are responsible for the supervision of equipment installation, process and equipment troubleshooting, on-site customer training, operation and maintenance seminars, and system and process optimization at customers' mills. Black Clawson also 6 PAGE relies on an international network of exclusive sales representatives and distributors. In particular, Black Clawson has concentrated on developing and strengthening its representative and distributor network in Southeast Asia and China, as most of the recent growth in the pulp and paper industry has been in those areas. Integration Strategy The Company intends to integrate Black Clawson with its existing operations to rationalize the combined manufacturing, distribution and administrative functions. In particular, the Company expects to consolidate certain operations in North America and Europe. The Company also intends to take advantage of Black Clawson's presence in the Southeast Asia and China markets for recycled paper equipment. There can be no assurance, however, that the Company will be able to successfully integrate Black Clawson with its existing business. Competition Black Clawson's major competitors in the market for its stock-preparation equipment are Voith Sulzer Papiertechnik GmbH, Beloit Corporation, Sunds Defibrator, Maschinen Fabrik Andritz AG, Kvaerner Pulping Technologies, Ahlstrom Machine Company, and Celleco AB. Smaller niche suppliers also exist in various markets served by Black Clawson. The principal competitive factors in the sale of Black Clawson's paper recycling and stock-preparation equipment are technology, product differentiation, engineering expertise, price, delivery capability, quality and service. GENERAL The Company was incorporated on November 12, 1991 as a wholly owned subsidiary of Thermo Electron. The Company commenced an initial public offering of its Common Stock on October 9, 1992. Thermo Electron owned approximately 88.1% of the total outstanding shares of the Company's Common Stock as of July 31, 1997. The Company's principal executive offices are located at 81 Wyman Street, Waltham, Massachusetts 02254, and its telephone number is (617) 622-1000. SELLING SHAREHOLDERS The Selling Shareholders currently hold Debentures convertible into the Shares which are the subject of this Prospectus. It is unknown if, when or in what amounts a Selling Shareholder may offer Shares for sale and the names of the Selling Shareholders who may sell the Shares. There is no assurance that the Selling Shareholders will sell any or all of the Shares offered hereby. 7 PAGE Because the Selling Shareholders may offer all or some of the Shares pursuant to the offering contemplated by this Prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the Shares that will be held by the Selling Shareholders after completion of this offering, no estimate can be given as to the principal amount of the Shares that will be held by the Selling Shareholders after completion of this offering. Other than as a result of the ownership of the Debentures, to the best of the Company's knowledge, none of the Selling Shareholders had any material relationship with the Company within the three year period ending on the date of this Prospectus.

Item 16. Exhibits. See the Exhibit Index included immediately preceding the exhibits to this Registration Statement. II-1 PAGE Item 17. Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; (iii)To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the II-2 PAGE securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-3 PAGE SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant hereby certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Waltham, Commonwealth of Massachusetts, on this 27th day of August, 1997.
