                                  Exhibit 99.1

    Cautionary Statements for the Purposes of the "Safe Harbor" Provisions of
              the Private Securities Litigation Reform Act of 1995

      Molten Metal Technology, Inc. (the "Company") desires to take advantage of
the "safe harbor" provisions of the Private Securities Litigation Reform Act of
1995 and is filing this Exhibit in order to do so. From time to time the Company
issues statements in public filings or press releases, or makes oral statements,
through an authorized spokesperson of the Company, that may be considered
forward-looking within the meaning of Section 27A of the Securities Act of 1933,
as amended, and Section 21E of the Securities Exchange Act of 1934, as amended.
These statements may include, among other items, (i) the Company's growth
strategies; (ii) anticipated trends in the Company's business; (iii)
developments in the Company's technology; (iv) the Company's plans to construct
CEP plants; (v) the Company's plans to enter into contracts with potential
customers and joint venture partners; (vi) receipt of research and development
funding; (vii) anticipated capital expenditures; (viii) anticipated revenues
from license fees and commercial operations; (ix) continued operations and
start-up of operations at facilities owned by the Company or its affiliates; (x)
expected sales of CEP systems by the Company and its partners; (xi) regulatory
acceptance of the Company's CEP technology; and (xii) the Company's financing
plans. These forward-looking statements are based largely on the Company's
expectations and are subject to a number of risks and uncertainties, certain of
which are beyond the Company's control. Actual results could differ materially
from these forward-looking statements as a result of the factors described below
and, as a result, there can be no assurance that the events described in any
such forward-looking statements will in fact transpire.

-     The Company's Catalytic Extraction Processing ("CEP") technology is a new
      technology for which there is no established market. Feedstock generators
      may not view the Company's CEP technology as an economically and
      environmentally acceptable means of disposing of their hazardous and
      non-hazardous wastes and industrial by-products, which could result in the
      Company experiencing difficulty in selling its CEP systems. Moreover, the
      economic terms under which generators may be willing to use the Company's
      CEP technology may not be profitable to the Company.

-     The Company has limited experience developing and constructing commercial
      CEP plants. In addition, the Company's "first of a kind" CEP plants have
      required larger capital expenditures and a longer period to develop and
      construct than originally anticipated by the Company. If the Company is
      not able to develop and construct CEP plants, particularly "second of a
      kind" plants, on time and under budget, this would have a material adverse
      effect on the Company's ability to successfully sell CEP plants to
      customers and to obtain financing for the development and construction of
      CEP plants.

-     To date, the testing of CEP largely has been limited to trials conducted
      under controlled testing conditions. No demonstration has yet been made
      that a commercial CEP system, once installed and operated at a customer's
      location, will process such customer's feedstock and 
<PAGE>   2
      recover commodity and specialty products of commercial quality and in
      significant quantities. There can be no assurance that the Company will be
      able to operate CEP systems on a sustained basis in commercial-scale use
      or that such systems can be operated profitably. In addition, the Company
      may experience problems associated with the engineering, construction and
      scale-up of its CEP systems, including cost overruns and start-up delays
      resulting from technical or mechanical problems or unfavorable conditions
      in the equipment or labor market.

-     The Company relies principally on subcontractors to build CEP system
      components and to assemble and install such systems. The Company's ability
      to deliver high quality systems on time will depend upon the reliability
      and performance of its subcontractors. The failure of a subcontractor to
      meet delivery schedules could cause the Company to default on its
      obligations to its customers. In addition, the Company's reliance on
      subcontractors for manufacturing, assembly and installation places a
      significant part of the Company's quality control responsibilities on
      these subcontractors. There can be no assurance that the Company will be
      able to continue to contract for the level of quality control required by
      the Company's customers.

-     The Company expects that a majority of its contracts will be performed on
      a "fixed-price" basis. In a fixed-price contract, the Company bears the
      full risk of cost overruns caused by estimates that differ from actual
      costs incurred or manufacturing delays during the course of the contract.
      If manufacturing or installation costs for a particular project exceed
      anticipated levels, gross margins would be materially adversely affected,
      and the Company could experience losses.

-     The Company expects that a significant portion of its revenues will come
      from sales of CEP systems overseas. International sales and operations may
      be limited or disrupted by the imposition of government controls, export
      license requirements, trade restrictions, changes in tariffs, difficulties
      in staffing, the transport of machinery, managing international operations
      and other factors. Regulatory compliance requirements differ among foreign
      countries and are also different from those established in the United
      States. If the Company's customers are unable to obtain the necessary
      foreign regulatory approvals on a timely basis, the Company's
      international sales could be materially adversely affected. Additionally,
      the Company's business may be materially adversely affected by
      fluctuations in currency exchange rates as well as increases in duty
      rates, difficulties in obtaining export licenses, ability to maintain or
      increase prices and competition. Since the bulk of expenses in connection
      with international contracts are often incurred in United States dollars,
      the Company may be subject to exchange rate risk. If the Company has
      significant international sales in the future denominated in foreign
      currencies, the Company may purchase hedging instruments to mitigate the
      exchange risk on these contracts.

-     Federal, state and local environmental legislation and regulations require
      substantial expenditures and impose liabilities for noncompliance.
      Environmental laws and regulations are, and will continue to be, a
      principal factor affecting demand for the systems and services being
      developed or offered by the Company. The level of enforcement activities
      by federal, 


                                        2
<PAGE>   3
      state and local environmental protection agencies and changes in
      regulations will also affect demand. Any changes in these regulations
      which increase compliance standards may require the Company to change or
      improve the CEP technology to meet more stringent regulatory requirements.
      To the extent that the burdens of complying with such laws and regulations
      may be eased, the demand for the Company's services could be materially
      adversely affected. In addition, international environmental regulations
      and enforcement of such regulations vary by country and are subject to
      changes which may affect the Company's operations.

-     The Company's CEP technology may not be successful in recovering materials
      in a form that is commercially usable or saleable. The Company also could
      be materially adversely affected by a decrease in the demand for the
      recovered materials. Some materials produced using CEP may have little to
      no commercial value, and may be considered wastes. Such waste may be
      classified as a hazardous or low-level radioactive waste (and may need to
      be handled as such) under current United States environmental regulations.
      In addition, such waste may need to be disposed of at specially permitted
      disposal facilities. In order to utilize such facilities, any waste
      produced by CEP must meet the acceptance criteria of the particular
      facility. Fees for disposal of wastes at such facilities, and the methods
      for calculating such fees, are subject to change. The Company's ability to
      operate its CEP systems profitably may be adversely affected by increases
      in such fees or changes in the methods of calculating such fees. The
      Company expects that the volume of residual waste streams produced from
      the processing of radioactive wastes with Q-CEP will be greater than those
      produced from other applications of CEP.

-     The Company's business exposes it to the risk that harmful substances will
      escape into the environment and cause substantial damages or injuries. The
      Company could be materially adversely affected by a claim that is not
      covered or only partially covered by insurance.

-     Denial, revocation or modification of required federal, state or local
      government permits could affect the Company's ability to conduct business
      in certain areas or to process certain types of wastes. In addition,
      failure to obtain or comply with the conditions of permits or approvals
      may adversely affect the introduction or operation of the Company's CEP
      systems and may subject the Company to penalties. The Company's ability to
      satisfy permitting requirements for a particular CEP system does not
      assure that permitting requirements for other CEP systems will be more
      easily satisfied, if at all. In addition, if new environmental legislation
      or regulations are enacted or existing legislation or regulations are
      amended or are interpreted or enforced differently, the Company or its
      customers may be required to obtain additional operating permits or
      approvals.

-     The Company will require substantial funds to construct the initial
      commercial CEP systems that it anticipates it will own and operate, to
      continue its development activities and to fund further operations at its
      research, development, testing and demonstration facility in Fall River,
      Massachusetts. The Company's future capital requirements could vary
      significantly and will depend on certain factors, many of which are not
      within the Company's control, including customers' decisions to finance,
      own and operate their CEP systems; the terms of any collaborative
      arrangements entered into by the Company; the progress of the Company's


                                       3
<PAGE>   4
      development of CEP; the nature and timing of permits required for CEP
      systems; and the availability and terms of alternative sources of
      financing.

-     The Company has historically been dependent on two customers, M4
      Environmental L.P. and the Department of Energy, for a substantial portion
      of its revenues. The Company does not expect to be receiving substantial
      revenues from M4 or the Department of Energy in 1997. The Company's future
      profitability is dependent upon its ability to commercialize successfully
      its CEP technology and to find alternative sources of revenue. There can
      be no assurance that the Company will generate sufficient revenue to
      achieve profitability.

-     The Company believes that its future success will depend, in part, on its
      collaborative relationships. Although the Company has entered into
      collaborative relationships with a number of entities, the failure of one
      or more of these relationships could materially adversely affect the
      Company's ability to sell CEP systems or have a material adverse effect on
      the Company's projected growth.

-     There are a number of companies which are in competition with the Company
      for waste processing, and any of these companies may develop technologies
      superior to those of the Company. In addition, the Company and its
      customers will compete with other producers of raw materials and recycled
      products for the sale of products recovered from the CEP process. Many of
      the Company's competitors are large companies with substantially greater
      financial resources than the Company. To the extent these competitors
      offer comparable services or products at lower prices or of higher
      quality, or more cost-effective waste disposal alternatives, the Company's
      ability to compete effectively could be adversely affected.

-     The Company's success depends, in part, on its ability to obtain
      additional patents, protect the patents which it owns, maintain trade
      secret protection and operate without infringing on the proprietary rights
      of third parties. The Company's ability to obtain approval of pending
      patent applications, develop additional proprietary processes that are
      patentable, obtain or license patents that will provide the Company with
      competitive advantages will directly affect the ability of the Company to
      successfully conduct its business. To the extent that the Company's
      patents are challenged by third parties, or that third parties
      independently develop similar or superior technologies, duplicate any of
      the Company's processes or design around the patented processes developed
      by the Company, the Company's ability to successfully conduct its business
      may be materially adversely affected. In addition, it is possible the
      Company may need to acquire licenses to, or to contest the validity of,
      issued or pending patents of third parties relating to the Company's
      technology. There can be no assurance that any license under such patents
      would be made available to the Company on acceptable terms, if at all, or
      that the Company would prevail in any such contest. In addition, the
      Company could incur substantial costs in defending itself in suits brought
      against the Company on its patents or in bringing suits against other
      parties. The costs of such licenses or patent litigation could materially
      adversely affect the Company's business.

-     The Company is highly dependent upon the efforts of its senior management
      and scientific staff. The loss of the services of one or more of these
      individuals may have a material 


                                       4
<PAGE>   5
      adverse effect upon the Company. The Company's future success will depend
      in large part upon its ability to attract and retain further highly
      skilled scientific, managerial, manufacturing and marketing personnel. The
      Company faces competition for hiring such personnel from other companies,
      research and academic institutions, government entities and other
      organizations. With the exception of William M. Haney, III, President and
      Chief Executive Officer, and Eugene Berman, Vice President of Government
      and External Affairs, the Company does not have any employment agreements
      with any of its employees for a specific time. There can be no assurance
      that the Company will continue to be successful in attracting and
      retaining such personnel.
