           WASTE MANAGEMENT ANNOUNCES FIRST QUARTER 2005 EARNINGS AND
             REAFFIRMS GUIDANCE ON FULL YEAR FINANCIAL PROJECTIONS

  PRICING INITIATIVES DRIVE REVENUE GROWTH FROM YIELD TO FIVE-YEAR HIGH OF 2.1%


HOUSTON - APRIL 28, 2005 - Waste Management, Inc. (NYSE: WMI) today announced
financial results for its first quarter ended March 31, 2005. Revenues for the
quarter were $3.04 billion as compared with $2.90 billion in the year ago
period, or an increase of 4.9%. Net income for the quarter was $150 million, or
$0.26 per diluted share, as compared with $152 million, or $0.26 per diluted
share in the prior year period. In the 2004 quarter, net income, before
considering a favorable $8 million cumulative effect of change in accounting
principle, was $144 million, or $0.25 per diluted share.

Net income for the first quarter of 2005 increased 4.2% as compared with the net
income for the first quarter of 2004 before considering the favorable cumulative
effect of change in accounting principle in 2004. The cumulative effect of
change in accounting principle in 2004 was related entirely to final
implementation of Financial Accounting Standards Board Interpretation No. 46,
Consolidation of Variable Interest Entities ("FIN 46").

"Our first quarter results reflect the strong progress we have made in improving
our pricing in all of our lines of business and in our ability to control costs
of maintenance, workers compensation, and salaries and wages," stated David P.
Steiner, Chief Executive Officer of Waste Management. "Our performance in the
quarter was right on track with our expectations and we are confident that we
will achieve our 2005 financial goals."

Steiner added, "We were pleased with our internal revenue growth due to higher
yield. At 2.1% for the quarter, this matches the highest level we have seen in
the past five years. Yield was higher across our entire business as we saw
improvements in all collection lines of business, in the three primary landfill
waste streams, and across our transfer stations and waste-to-energy facilities.
The revenue increase due to yield grew 2.9% if you include the favorable impact
of our fuel surcharge program. As we see continued cost pressures in our
operations, we will maintain our focus on increasing prices to recover those
costs for the remainder of 2005 and beyond."


KEY HIGHLIGHTS FOR THE QUARTER
   o  Net cash provided by operating activities of $508 million.
   o  Free cash flow (a) of $420 million.
   o  Capital expenditures of $185 million.
   o  Internal revenue growth on base business of 3.1%, with 2.1% of that from
      average yield and 1.0% from volume. The yield component excludes combined
      positive impacts of 0.9% related to higher recycling commodity prices,
      higher fuel surcharges and changes in electricity rates at Independent
      Power Production facilities.
   o  Acquisitions net of divestitures contributed 0.6% to higher revenues in
      the quarter.
   o  Price increases improved to 4.0% on our commercial customer base and to
      3.2% on our total collection customer base.
   o  $213 million returned to shareholders in the form of $114 million in cash
      dividends and $99 million in common stock repurchases.

The Company noted several items which impacted the current quarter's results:
   o  A $0.05 per diluted share gain related to the divestiture of the Ridge
      landfill in Canada, which closed in January of 2005.
   o  A $0.03 per diluted share charge to settle a lawsuit with a group of
      shareholders who had opted not to participate in the settlement of the
      class action lawsuit against us related to 1998 and 1999 activity.
   o  A $0.02 per diluted share decrease in earnings related to the cost of a
      seven-week strike in New Jersey and accelerated expenses under our new
      long-term incentive plan for those employees eligible for retirement.

Steiner continued, "There were a number of other encouraging factors in our
first quarter results. Net cash provided by operating activities and free cash
flow were both strong for the quarter. We returned $213 million to shareholders
in the form of our $0.20 per share quarterly dividend and our share repurchase
program. Higher volumes also contributed 1.0% to the increase in revenues, even
in light of the unusually wet weather that occurred in a number of our key
markets. We also improved productivity in our commercial and industrial lines of
business, which is an important component of our cost control initiatives.

"We expect the momentum of our pricing programs to carry forward through the
remainder of the year. We reported today that, based on the success of our
landfill pricing study during the first quarter, we will expand that study to
include 23 transfer stations, plus a total of 58 landfills and transfer stations
in four Market Areas. Today we also announced a seasonal price increase plan for
the temporary roll-off segment of our business, similar to seasonal pricing done
by other industries during periods of peak demand."

Steiner concluded, "We are confident about the outlook for our price and
operational initiatives and we reaffirm our full-year financial projections
which we issued on February 10th of this year. In reaffirming our earnings
projection, we note that it is within the mid-to-upper end of the analysts'
current range of $1.50 to $1.60 per diluted share."

   (a) The Company included its free cash flow, which is a non-GAAP financial
   measure, herein because it believes that investors are interested in the cash
   produced by the Company from non-financing activities that is available for
   uses such as the Company's acquisition program, its share repurchase program,
   its scheduled debt reduction and the payment of dividends. The Company
   defines free cash flow as:


   o  Net cash provided by operating activities

   o  Less, capital expenditures

   o  Plus, proceeds from divestitures of businesses, net of cash divested, and
      other sales of assets

   The Company's definition of free cash flow may not be comparable to similarly
   titled measures presented by other companies. The Company has reconciled its
   free cash flow as presented herein to cash flow from operations, which is the
   most comparable GAAP measure, in the accompanying schedules.

Certain statements contained in this press release include statements that are
"forward-looking statements." Outlined below are some of the risks that the
Company faces and that could affect our financial statements for 2005 and beyond
and that could cause actual results to be materially different from those that
may be set forth in forward-looking statements made by the Company. However,
they are not the only risks that the Company faces. There may be additional
risks that we do not presently know or that we currently believe are immaterial
which could also impair our business. We caution you not to place undue reliance
on these forward-looking statements, which speak only as of their dates. We
undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.
In addition, the Company, from time to time, provides estimates of financial and
other data relating to future periods. Such estimates and other information are
the Company's expectations at the point in time of issuance but may change at
some future point in time. By issuing such estimates the Company has no
obligation, and is not undertaking any obligation, to update such estimates or
provide any other information relating to such estimates. The following are some
of the risks we face:

   o  the effects competition may have on our profitability or cash flows,
      including the negative impact to our yield on base business resulting from
      price roll-backs and lower than average pricing to retain and attract
      customers;

   o  our inability to maintain or expand margins as volumes increase if we are
      unable to control variable costs or our fixed cost base increases;

   o  increases in employee-related costs and expenses, including health care
      and other employee benefits such as unemployment insurance and workers'
      compensation, as well as the costs and expenses associated with attracting
      and retaining qualified personnel;

   o  possible increases in expenses due to fuel price increases or fuel supply
      shortages;

   o  the effect that fluctuating commodity prices may have on our operating
      revenues and expenses;

   o  the general effects of a weak economy, including the resulting decreases
      in volumes of waste generated;

   o  external factors beyond our control, such as higher interest rates and the
      possible inability of insurers to meet their obligations, both of which
      may cause increased expenses;

   o  the effect the weather has on our quarter to quarter results, as well as
      the effect of extremely harsh weather on our operations;


   o  possible changes in our estimates of site remediation requirements, final
      capping, closure and post-closure obligations, compliance and regulatory
      developments;

   o  the possible impact of regulations on our business, including the cost to
      comply with regulatory requirements and the potential liabilities
      associated with disposal operations;

   o  our ability to obtain and maintain permits needed to operate our
      facilities;

   o  the effect of limitations or bans on disposal or transportation of
      out-of-state waste or certain categories of waste;

   o  possible charges against earnings as a result of shut-down operations,
      uncompleted development or expansion projects or other events;

   o  the effects that trends toward requiring recycling, waste reduction at the
      source and prohibiting the disposal of certain types of wastes could have
      on volumes of waste going to landfills and waste-to-energy facilities;

   o  possible diversions of management's attention and increases in operating
      expenses due to efforts by labor unions to organize our employees;

   o  the outcome of litigation or threatened litigation;

   o  the need for additional capital if cash flows are less than we expect or
      capital expenditures are more than we expect, and the possibility that we
      cannot obtain additional capital on acceptable terms if needed;

   o  possible errors or problems upon implementation of new information
      technology systems; and

   o  possible fluctuations in quarterly results of operations or adverse
      impacts on our results of operations as a result of the adoption of new
      accounting standards or interpretations.

     Additional information regarding these and/or other factors that could
     materially affect results and the accuracy of the forward-looking
     statements contained herein may be found in Part I, Item 1 of the Company's
     Annual Report on Form 10-K for the year ended December 31, 2004.

(c)  The summary of free cash flows has been prepared to highlight and
     facilitate understanding of the principal cash flow elements. Free cash
     flow is not a measure of financial performance under generally accepted
     accounting principles and is not intended to replace the consolidated
     statement of cash flows that was prepared in accordance with generally
     accepted accounting principles. We continue to project full-year 2005 free
     cash flow to be in the range of $1.1 billion to $1.2 billion, based on
     estimated net cash provided by operating activities in the range of $2.25
     billion to $2.35 billion, capital expenditures of between $1.25 bilion and
     $1.35 billion, and proceeds from divestitures, net of cash divested and
     other sales of assets of $125 milion to $150 million.

(a)  Prior period information has been reclassified to conform to 2005
     presentation.

(b)  Reflected in the quarter ended December 31, 2004 results was a $23 million
     reduction in landfill amortization expense. This reduction was related
     primarily to adjustments to our fully accrued landfill final capping
     obligations and was a result of fourth quarter event-driven changes as well
     as changes in certain estimates as a result of our annual landfill review
     process.
