         HOUSTON, TEXAS, FEBRUARY 10, 2000 --Waste Management, Inc. (NYSE: WMI)
today announced that it intends to sell the 60.5% of the shares in Waste
Management New Zealand Limited, which it owns.

Zealand and an institutional offering in selected overseas markets.

         It is expected that the offering will be launched before the end of
March 2000.

         This transaction is part of a global divestiture program whereby WMI is
rationalizing its international waste assets with a view to focusing on its core
business in the U.S. market.

         The shares will not be or have not been registered under the U.S.
Securities Act of 1933 and may not be offered or sold in the United States
absent registration or an applicable exemption from registration requirements.

to risks and uncertainties, any one of which could cause actual results to

     companies with its existing operations, including risks and uncertainties
     relating to its ability to achieve projected earnings estimates, achieve

     making; and the risks and uncertainties regarding government-forced
     divestitures;

o    The Company's ability to continue its expansion through the acquisition of

     acquisitions, the ability of the Company to accurately assess the prior
     existing liabilities and assets of acquisition candidates and the
     restraints imposed by federal and state statutes and agencies respecting
     market concentration and competitive behavior;

o    The effect of competition on the Company's ability to maintain margins on
     existing or acquired operations, including uncertainties relating to
     competition with government owned and operated landfills which enjoy
     certain competitive advantages from tax-exempt financing and tax revenue
     subsidies;

o    The potential impact of environmental and other regulation on the Company's
     business, including risks and uncertainties concerning the ultimate cost to
     the Company of complying with closure requirements and post-closure
     liabilities associated with its landfills and other environmental
     liabilities associated with disposal at third party landfills and the
     ability to obtain and maintain permits necessary to operate its facilities,
     which may impact the life, operating capacity and profitability of its
     landfills and other facilities;

o    The impact of pending or threatened litigation and/or governmental
     inquiries involving the Company;

     remediation requirements, closure and post-closure issues, compliance and
     other audits and regulatory developments;

o    The effectiveness of changes in management and the ability of the Company
     to retain qualified individuals to serve in senior management positions;
     and

o    The uncertainties relating to the Company's proposed strategic initiative,
     including the Company's ability to obtain permanent amendments to its bank
     credit facilities to allow for the divestiture of assets, and the
     willingness of prospective purchasers to purchase the assets the Company
     identifies as divestiture candidates on terms the Company finds acceptable,
     the timing and terms on which such assets may be sold, uncertainties
     relating to regulatory approvals and other factors affecting the ability of
     prospective purchasers to consummate such transactions, including the
     availability of financing and uncertainties relating to the impact of the
     proposed strategic initiative on the Company's credit ratings and
     consequently the availability and cost of debt and equity financing to the
     Company.
