Water bodies in several tropical countries (including India) are invaded by
a floating aquatic weed called water hyacinth. In many cases it covers the
entire water surface. Its leaves enhance the evaporative surface of the
water body and thus cause rapid depletion of water. In most countries it is
considered a menace, but  it can very easily be converted into biogas. All
one needs is a biphasic digester. in which the first phase converts the
material into organic acids, which then flow into the second phase, which
is the actual biogas digester.  Water hyacinth should therefore be
considered to be a useful source of clean energy and not a menace.
