Work has been done on this by researchers working at the Toronto, 
Denver and Portland OR zoos, among others.

I know of at least three freely available papers that bear (pun 
intended) on the issue (as previously):

        "Energy Production from Zoo Animal Wastes", Klasson and
        Nghiem, 2003 (poster here
        <http://www.ornl.gov/sci/eere/PDFs/Zoodoopost.pdf>, paper here
        <http://www.rhinoresourcecenter.com/pdf_files/123/1238059703.pdf>)

        "Biogas from elephant dung: a means of mitigating
        human-elephant conflict", Wijeyamohan (here
        <http://www.asesg.org/PDFfiles/Gajah/22-62-Wijeyamohan.pdf>)

        "Biogas as Renewable Energy from Organic Wastes", Karki et al
        (here <http://www.eolss.net/Sample-Chapters/C17/E6-58-09-10.pdf>)


And another, hard to find on-line:

        "Biogas Production from Elephant Dung at the National Elephant
        Institute Project", by The National Elephant Institute (Thailand)
