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.
How is electricity produced from bagasse?
The amount of energy present in the bagasse is more than enough to meet the mechanical and thermal demands of mill operation, such as crushing and the evaporation of juice to give crystals. This is achieved at the moment by burning the bagasse to generate steam in specially designed boilers.
Is bagasse a source of energy?
Bagasse is the dry pulpy residue that remains after extraction of juice from sugar cane and similar plants. CO2 emissions from burning bagasse are less than the amount of CO2 that the sugarcane plant absorbed while growing, which makes it a renewable source of energy that is also greenhouse gas-neutral.
What is bagasse power plant?
Bagasse, termed as a captive biomass, is fibrous in nature. It has a calorific value of 2,300 kcal/kg. Bagasse is an excellent raw material for power generation. It already provides a stable and reliable source of electricity and steam to power the sugar mills.
What is an example of cogeneration?
The case for cogeneration in industry is strong, as many industrial processes require steam and/or heat. One such example is the Columbus Water Works, where biogas generated as a by-product of wastewater treatment was used as a fuel source to run the cogeneration plant.
Which boiler is used in sugar factory?
Steam boilers are used in sugar mills to generate electricity and for heat in various stages of production, such as crystallization process. This process converts the sugar syrup into sugar crystals.
Which part of the factory is bagasse used?
Bagasse is principally used in the manufacturing process of paper, pulp and building materials as well as a biofuel for the production of energy, heat and electricity.
How much does bagasse cost?
thousand cubic feet, a boiler efficiency of 80% for natural gas and 53.9% for bagasse, one ton of bagasse at 50% moisture content is worth $13, as of January, 2015. Similar calculations reveal that at 32% moisture content the bagasse is worth $22 per ton.
What are the disadvantages of bagasse?

What is bagasse in English?
bagasse in American English (bəˈgæs ) US. noun. the part of sugar cane left after the juice has been extracted, or the residue of certain other processed plants. it is used for fuel and in making fiberboard.
What is the byproduct of sugarcane?
The four main byproducts of the sugarcane industry are cane tops, bagasse, filter muds and molasses (Figure 1).
Why is cogeneration not widely used?
Barriers to cogeneration These companies emphasize their own short-term profits over the long-term environmental costs of inefficient use of non-renewable resources. Other barriers to cogeneration are the falsely low costs of fossil fuels , relative to their true, longer-term costs and future scarcity.
How are bioelectric plants helping the sugarcane industry?
The aim is to increase the amount of electricity generated by sugarcane biomass to nearly 14% by 2030. The gradual installation of modern bioelectric plants in some sugar mills will also increase the odds of reaching that goal. ■ Reduction of ethanol and sugar production costs. ■ Reduction or elimination of fossil fuels dependence.
Where did bagasse and blended biomass cogeneration take place?
Bagasse cogeneration (which is the term most countries use for combined heat and power) was initiated in Mauritius and Hawaii. By the 1926–27 season, 26% of Mauritius’ and 10% of Hawaii’s electricity generation came from sugar factories. Bagasse cogeneration is also the basis of power generation efficiency in Cuba’s sugar industry.
How much money is needed for cogeneration plant in India?
The Sugar Development Fund of the Union Government provides 30% funding of capital investment and the remaining is secured through institutional funding. An investment of around Rs 4.50 crore per MW is needed to start a cogeneration plant in a cooperative factory.
How much does the government give to cooperative sugar factories?
According to a Government policy regulating cooperative sugar factories, the State Government provides 5% of the capital expenditure on the cogeneration project while the factory concerned puts in an equal amount.
