Ladies and Gentlemen:

      You have requested our opinion in connection with the filing by World
Waste Technologies, Inc., a California corporation (the "Company"), of a
Registration Statement on Form S-1 (the "Registration Statement"), with the
Securities and Exchange Commission (the "Commission"), including a related
prospectus filed with the Registration Statement (the "Prospectus"), covering
the offering for resale of up to 31,928,934 shares of common stock of the
Company, par value $0.001 per share (the "Common Stock"), comprised of (i)
6,652,917 shares (the "Issued Shares") of Common Stock that are issued and
outstanding, (ii) 5,851,145 shares (the "Warrant Shares") of Common Stock that
are issuable upon the exercise of outstanding warrants (the "Warrants"), and
(iii) 19,424,872 shares (the "Conversion Shares") of Common Stock that are
issuable upon the exercise of conversion rights (the "Conversion Rights") by
holders of the Company's Series A preferred stock and Series B preferred stock.

      In connection with this opinion, we have examined and relied upon (i) the
Registration Statement and the Prospectus; (ii) the Company's Articles of
Incorporation, as amended to date; (iii) the Company's Bylaws, as amended to
date; (iv) the Certificates of Determination, as amended to date, that set forth
the rights, preferences and privileges of the Company's Series A preferred stock
and Series B preferred stock; (v) the Warrants; and (vi) originals or copies
certified to our satisfaction of such other records, documents, certificates,
memoranda and other instruments as in our judgment are necessary or appropriate
to enable us to render the opinion expressed below. We have assumed (without
investigation or inquiry) the genuineness and authenticity of all documents
submitted to us as originals, the conformity to originals of all documents
submitted to us as copies thereof and the due execution and delivery of all
documents where due execution and delivery are a prerequisite to the
effectiveness thereof. We have also assumed (without investigation or inquiry)
that all factual statements made by the Company in the Registration Statement
are accurate and complete.

      The law covered by our opinion is limited to the internal laws of the
State of California. We neither express nor imply any opinion (and we assume no
responsibility) with respect to any other laws or the laws of any other
jurisdiction or with respect to the application or effect of any such laws.



      The only opinion rendered by us is set forth below, and no opinion may be
implied or inferred beyond that expressly stated below.

      Based upon the foregoing, and in reliance thereon, we are of the opinion
that: (i) the Issued Shares are validly issued, fully paid and nonassessable;
(ii) the Warrant Shares, when issued and paid for in accordance with the terms
of the Warrants, will be validly issued, fully paid and nonassessable; and (iii)
the Conversion Shares, when issued in accordance with the terms of the
Conversion Rights, will be validly issued, fully paid and nonassessable.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and further consent to the use of our name wherever
appearing in the Registration Statement. In giving such consent, we do not
thereby admit that we are within the category of persons whose consent is
required under Section 7 of the Securities Act of 1933 or the rules and
regulations of the Commission thereunder.


                                     Very truly yours,

                                     /s/  Troy & Gould Professional Corporation
