In areas where the rainfall is scanty, and there are no trees, dung is used as the main cooking fuel. In the high Himalaya, above the tree line, yak dung is the only fuel available to the locals. The ash content of dung is normally very high. In the case of animals eating mainly grass, the ash would consist mainly of silica. I have heard of a of filter press, which can remove the water from the dung along with the dissolved minerals. This would leave a product with a higher calorific value. It can be briquetted and sold as a standard fuel.<o:p></o:p></p></div><div><p class=MsoNormal>Yours<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'>A.D.Karve<o:p></o:p></p></div><div><p class=MsoNormal>On Tue, Dec 7, 2010 at 12:47 AM, Crispin Pemberton-Pigott <<a href="mailto:crispinpigott@gmail.com">crispinpigott@gmail.com</a>> wrote:<o:p></o:p></p></div></div></body></html>
