[Stoves] Dung as fertilizer and fuel

[adkarve]

The sugar industry in India uses bagasse containing about 50% moisture as
fuel, to produce steam for generating electricity. Dry dung cakes,
especially those that contain straw and dry leaves as additives, have
definitely a higher calorific value than bagasse with 50% moisture. The
western part of Maharashtra State in India, has a well established sugar
industry as well as a well established dairy industry. The dung available
with the dairies can be mechanically briquetted, after squeezing the water
out of the dung by means of a filter press. This process would yield the so
called dung tea, that can go back to the field. Briquettes made from the
dung solids can be burned in the boilers of the sugar factory to generate
electricity or sold to anybody who may want to use them as fuel. Making
biogas from dung is a wasteful process. One gets only 25 per cent of the
original calorific value, if the dung is converted into methane.
