What is bagasse cogeneration?
Basically it is a fibrous material that remains behind after the crushing of sugar cane. Bagasse has good calorific value and burns very easily. Sugar industry requires electricity and steam in the production process.
Is bagasse a renewable source of energy?
Bagasse is a renewable fuel and is essentially greenhouse gas neutral because the carbon dioxide produced during bagasse combustion is offset by the carbon dioxide absorbed by the photosynthesis of sugarcane in the field.
Which energy is obtained from sugarcane waste or bagasse?
For every 100 tons of Sugarcane crushed, a Sugar factory produces nearly 30 tons of wet Bagasse. Bagasse is often used as a primary fuel source for Sugar mills; when burned in quantity, it produces sufficient heat and electrical energy to supply all the needs of a typical Sugar mill, with energy to spare.
What is cogeneration in sugar industry?
Cogeneration is a broader term associated with sugar industries. Cogeneration systems serve two purposes- generate electricity from steam using waste materials obtained during industrial process and also process heat for industry itself.
Where is the cogeneration of bagasse taking place?
Cogeneration of Bagasse. Cogeneration of bagasse is one of the most attractive and successful energy projects that have already been demonstrated in many sugarcane producing countries such as Mauritius, Reunion Island, India and Brazil.
Where does the majority of sugarcane bagasse come from?
Sugarcane bagasse is a large-volume agriculture residue that is generated on a ~540 million metric tons per year basis globally with the top-three producing countries in Latin America being Brazil (~181 million metric ton yr -1 ), Mexico (15 million metric ton yr -1 ), and Colombia (7 million metric ton yr -1 ), respectively.
How can bagasse be used for bioenergy in Pakistan?
Considering the fact that Pakistan is among the world’s top-10 sugarcane producers, the potential of generating electricity from bagasse is huge. Almost all the sugar mills in Pakistan have in-house plants for cogeneration but they are inefficient in the consumption of bagasse.
Why is it good to burn bagasse in sugarcane mills?
Burning bagasse also removes a waste product through its use as a feedstock for the electrical generators and steam turbines. Most sugarcane mills around the globe have achieved energy self-sufficiency for the manufacture of raw sugar and can also generate a small amount of exportable electricity.
