Pakistan being the fifth largest sugarcane producer in the world
has the potential to generate more than 2,000 MW electricity
Cogeneration is a high efficiency energy system that produces
both electricity (and mechanical power) and valuable heat from a
single fuel source.
Bagasse (process waste of sugar industry) is a fibrous residue
of cane stalk obtained after crushing. It contains only 4% ash
and no sulphur and has a Net Calorific Value of 1,850-1,900
kcal/kg. When burned in quantity, bagasse produces sufficient
heat energy to supply all the needs of a typical sugar mill,
with energy to spare. To this end, a secondary use of bagasse is
Co-Generation plants based on high pressure boilers is gaining
momentum worldwide. Co-Generation by sugar mills by utilizing
bagasse and coal provides one of the most economically viable
option for thermal power generation, yet it remains largely
unexploited in Pakistan.
