From Cane to Crystals
Sugarcane is broadly classified into three varieties viz., Early, General, and Unapproved. Typically sugarcane seeds are sown in the months of February and October every year. The first seed growth is known as Plant and subsequent growth after harvesting from the stem is known as Ratoon. The Early variety has more sugar content than the General variety.
All farmers within the command area of our Mills are provided with a calendar which tells them when they can expect a Mill Supply Ticket (Purchy) against which they will deliver their produce.
The farmers then harvest the cane and transport it to the mill. Sometimes the cane is also bought at the mill's own centers within the command area from where it is then transported in trucks or via rail to the mill.
Cane is weighed using an electronic weigh bridge and unloaded into cane carriers. It is then prepared for milling by knives and shredders. Sugarcane juice is then extracted by pressing the prepared cane using mills consisting of three rollers.
Extracted juice mixed with water is weighed and sent to the boiling house for further processing. Residual bagasse is sent to boilers for use as fuel for steam generation.
This juice is heated and then treated with milk of lime and Sulphur Dioxide. The treated juice is heated further and sent to clarifiers for continuous settling. The settled mud is filtered by vacuum filters and clear juice is returned for further processing while the Oliver cake is sent out.
The clear juice is evaporated to a syrup, bleached by Sulphur Dioxide and sent to vacuum pans for further concentration and forming sugar grains. Crystals are broken into a desired size and the crystallized mass is then dropped in the crystallizers to exhaust the mother liquor of its sugar to the extent possible. This is then centrifuged for separating the crystals from molasses. The molasses is boiled again for further crystallization.
Thus, the original syrup is desugarised progressively (usually thrice) until finally a viscous liquid is obtained from which sugar can no longer be recovered. This liquid, which is called final molasses, is sent to the distillery for making alcohol.
The sugar separated from molasses in the centrifuge is dried, bagged, weighed, and sent to storage houses.
Sugar is made in different sizes and assigned grades i.e. large, medium and small.
Molasses
Molasses is the only by-product obtained in the preparation of sugar through repeated crystallization. The yield of molasses per ton of sugarcane varies in the range of 4.5% to 5%. Molasses is mainly used for the manufacture of alcohol, yeast and cattle feed. Alcohol in turn is used to produce ethanol, rectified spirit, potable liquor and downstream value added chemicals such as acetone, acetic acid, butanol, acetic anhydride, MEG etc.
The state government controls the export of molasses through export licenses issued every quarter. Molasses and alcohol-based industries were decontrolled in 1993 and are now being controlled by the respective state government policies. Nearly 90% of molasses produced is consumed by the industrial alcohol manufacturers and the remaining 10% is consumed by the potable alcohol sector.
Bagasse
Bagasse is a fibrous residue of cane stalk that is obtained after crushing and extraction of juice. It consists of water, fiber, and relatively small quantities of soluble solids. The composition of bagasse varies based on the variety of sugarcane, maturity of cane, method of harvesting and the efficiency of the sugar mill. Bagasse is usually used as a combustible in furnaces to produce steam, which in turn is used to generate power. It is also used as a raw material for production of paper and as feedstock for cattle.
By making use of bagasse, sugar mills have been successful in reducing dependence for power on state electric boards as it can procure up to 90-95% of its total power requirement through captive generation from steam turbines.
Fly Ash
Fly Ash is the residual output from the boiler furnace after bagasse has completely burnt out. This fly ash is used as a substitute for firewood. It is rich in potassium and is also used by local farmers for cultivation.
Press Mud
Press Mud, also known as oliver cake or press cake, is the residual output after the filtration of the juice. It is mixed with spent wash from the distillery and cultivated to produce high quality bio-manure.

Soil fertility is seriously impaired with excessive use of chemical fertilizers. Studies conducted to ascertain the reasons for fall in grain production have indicated that soil where chemical fertilizers are used in excess tends to lose organic carbon over time which in turn adversely affects its fertility.
Regular use of bio-manure can help address this challenge. HeetBindal global pvt ltd is a rich source of carbon for the soil and other important elements like Nitrogen, Phosphorus, Potassium (NPK). The product balances organic carbon in the soil and preserves its fertility better than other competing offerings.

Commitment to Quality
At HeetBindal global Pvt Ltd, thanks to our finely tuned processes, we are able to produce sugar of the highest quality. A reflection of our steadfast commitment to quality, some of the measures we employ include:
Grades of Sugar Manufactured by HeetBindal global Pvt Ltd
At HeetBindal global pvt ltd we produce sugar of following grades:
Every year HeetBindal global Pvt Ltd conducts a survey of its command area to record the total cane cultivated area. This survey, among other things, also helps us understand the different varieties of sugarcane grown by farmers each year.
Post this, all sugarcane farmers within the command area of the mill are given a calendar which tells them when they can expect a Mill Supply Ticket (Purchy) against which they will supply their produce.
The calendar is distributed over 180 days. Based on the maturity and recovery expected from the varieties, the distribution is worked out in the calendar.
After receiving the purchy, the farmer harvests the cane and transports it to the mill gate. Farmers located in far flung locations supply their produce at mill's centers from where the sugar cane is then transported in trucks or through rail to the mill.
HeetBindal global pvt ltd has a total of 1,41,155 hectares of cultivable land under in its command areas. This area covers 1,344 villages and has over 95 centres. The company purchases cane from over 1,13,577 farmers. Assuming that each farmer has a family of five, over half a million people across UP remain directly dependent on the Company's for their livelihood.
