<P align="left" style="font-size: 10pt">Gentlemen,



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I am Vice President and Assistant General Counsel &#151; Corporate &#038;
Securities of Waste Management, Inc., a Delaware corporation (the &#147;Company&#148;),
and have acted in such capacity in connection with the sale of 13,958 shares of
the Company&#146;s common stock, par value $0.01 per share (the &#147;Common Stock&#148;),
pursuant to the exercise of three (3)&nbsp;warrants dated June&nbsp;21, 1996 (the
&#147;Warrants&#148;). The 13,958 shares of Common Stock are being issued under a
registration statement on Form&nbsp;S-3 (No.&nbsp;333-97697) filed under the Securities
Act of 1933, as amended (the &#147;Registration Statement&#148;).


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I have examined corporate documents of the Company, including its
Certificate of Incorporation and Bylaws, and resolutions adopted by its board
of directors and committees thereof. I have also examined the Registration
Statement, together with the exhibits thereto, and such other documents that I
have deemed necessary for the purposes of expressing the opinion contained
herein. I have relied on representations made by and certificates of the
officers of the Company and public officials with respect to certain facts
material to my opinion. I have made no independent investigation regarding
such representations and certificates.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Based upon the foregoing, I am of the opinion that when payment for the
shares of Common Stock has been made pursuant to the Warrants, the Common Stock
issued thereupon will be validly issued, fully paid and nonassessable.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.
