Sugarcane cultivation requires a tropical or subtropical climate, with a minimum of 600 mm (24 in) of annual moisture. It is one of the most efficient photosynthesizers in the plant kingdom, able to convert up to 2 percent of incident solar energy into biomass. In prime growing regions, sugarcane can produce 20 kg for each square meter exposed to the sun.
RSCL Bio-D - Microbial Compost Starter Culture
RSCL Bio-D is a consortium of live aerobic microorganisms specially developed for composting or degrading organic wastes like sugar factory pressmud, distillery spent wash, cow dung, poultry manure, coir pith, sugarcane trash, bagasse, city garbage and other agricultural wastes. This ecofriendly microbial compost starter culture helps to accelerate the organic matter decomposition with increased himification and shortened composting time. RSCL Bio-D is harmless to human beings, animals, birds and plants. It is fully biodegradable.
Packing & Storage:
RSCL Bio-D is packed in 50 kg HDPE bags and 1 kg packets. RSCL Bio-D can be stored for 1 year in a cool and dry place with temperature less than 30 0C and should be kept away from direct sunlight.
The process adopted in the manufacture of sugar is Double Sulphitation Process.
Sugar Factory consists of the following five main stations:
Mill House: Mill house is the cane crushing unit which consists of cane carrier, cane cutter having cutting knives, milling tandem, bagasse carrier and conveyor. Cane feeding to the cane carrier is done by unloaders and feeder table. As the cane carrier moves, the cane kicker evens out cane load in the cane carrier and then two sets of cane knives cut the cane into small pieces. This process of cane cutting is called 'cane preparation. These cane pieces then, pass through different mills and the juice is extracted. The mills are driven by D.C.motors. The residue which comes out of the mill after extraction of juice is called bagasse.
Boiler House: Boiler generates steam by burning the bagasse. The steam is used in powerhouse, boiling house, curing house. The steam required by the Sulphitation process varies from 42 - 45 % on cane crushed per hour.
Power House: The high pressure steam generated by the boiler is utilized for production of power by the turbo-alternators. The power produced is used for captive needs and the surplus power is exported to the government grid. The low pressure steam that comes out from the turbo alternator is utilized for boiling the extracted juice.
Clarification & Boiling House: The juice extracted by the mills is measured by juice flow system. The measured juice is heated in juice heater in two stages. First the juice is heated by the vapours from fourth and third bodies of evaporator in different heaters. This heating is called primary heating. The heated juice is treated with milk of lime and sulphur-di-oxide to coagulate maximum impurities and sent for secondary heating. The secondary heating is done with vapours from second body of evaporator and vapours from the first body or exhaust steam. The treated juice is passed to clarifier, where in clear juice is removed from the top and settled mud at the bottom is separated. To extract sugar from the mud, it is taken to vacuum filter in which juice and filter cake are separated. Juice is taken back to process and the mud is disposed as solid waste. Clear juice from clarifier is taken to evaporator for evaporating its water content. First body is heated by exhaust steam, and other bodies by the vapours of the previous body.
The total water evaporated in the evaporator is 75-80 % percent. The juice after evaporation is called as syrup. This syrup is normally of 60 % solids of its total weight. The syrup is then sulphited in syrup Sulphitation tower.

Cogeneration Power Service
Cogeneration involves the use of high pressure Boilers for producing steam and Turbo generators for generating power. The high pressure steam passes through the turbine and generates power. The low pressure steam from the turbine is used in the processing of sugar. This process of utilization of steam for generating power and for processing of sugar is called cogeneration.
The cogeneration units generate 54 MW of “Green power" using bagasse as fuel. After meeting the captive requirement, surplus power of about 32 MW is supplied to the state grid. The cogeneration units generate 195.16 million units of power annually. The surplus power of 120.52 million units is supplied to the state grid every year.
The 22 MW plant at unit-2 has been registered as a CDM project on January 15th, 2006. This project reduces 81,628 tonnes of Co2 equivalent per annum. For each ton of Co2 emission that is avoided by this project, we get a Carbon Emission reduction Certificate (CER) This project generates 81,628 CER’s per annum. These CER’s are sold to countries that have emission reduction commitments. This cogeneration plant is the first plant in India to install Air cooled condensers instead of water cooled condensers for its turbines. Even though the Air cooled condensers incur a much higher investment cost than the water cooled condensers, it is environment friendly and they totally eliminate the use of water. This is an important environment feature given the scarcity of water in the region and a positive step towards water conservation.
RSCL has adapted clean technologies in all its cogeneration plants which have led to reduction in greenhouse gas emissions. With the adaptation of clean technologies for power generation, we have made this world a better place.
India is the original home for Sugar. From Sharkara in Sanskrit to Sugar in English, it has been a long journey of time and space with quite a few intermediaries. Alexander and his troops were amazed by this honey without bees. But it was the Arabs who introduced Sugarcane to Europe and from there the Spaniards took it to the Americas.
