Bajaj Hindusthan Limited (BHL) was incorporated on 23rd November,
1931 under the name - The Hindusthan Sugar Mills Limited – on the
initiative of Jamnalal Bajaj - a businessman, confidante, disciple and
adopted son of Mahatma Gandhi. He sought Gandhiji's blessings in this new
venture, which, apart from being a sound commercial proposition would
also meet a national need. Till then, there were barely thirty sugar factories
in the country.
The site selected for the first plant was at Golagokarannath, district
Lakhimpur Kheri in the Terai region of Uttar Pradesh (UP), an area rich in
sugar cane. The original capacity of the factory was 400 tons of cane
crushed per day (tcd). Subsequently, this capacity was increased in stages
and is currently 13,000 tcd. The distillery Unit at this plant commenced
production during the end of World War II in 1944. In the initial few years,
the major output was in the form of power alcohol as an additive to petrol,
which was then in short supply. The unit was the first to supply alcohol-
mixed petrol to the army.
In 1967, a new Company - Sharda Sugar & Industries Limited - was
established as a subsidiary of Hindusthan Sugar Mills Limited. Under this
new subsidiary, a sugar plant with a cane crushing capacity of 1400 tcd was
set up in 1972 at Palia Kalan, a large cane supplying centre at a distance of
about 70 kilometres from Golagokarannath. The objective of this new Unit
was primarily to help the cane growers of the area supply their produce to
the new location closer to their fields, thereby cutting down on
transportation costs. The capacity was subsequently increased in stages to
reach the present 11,000 tcd.
In the year 1988, The Hindusthan Sugar Mills Limited was renamed as
Bajaj Hindusthan Limited and shortly thereafter in 1990, Sharda Sugar &
Industries Limited was amalgamated with Bajaj Hindusthan Limited.
The Company embarked on an aggressive Greenfield expansion drive
in 2003-2007, starting with a plant at Kinauni, near Meerut (UP),
which was completed in a record time of just seven months as against the
industry norm of 18-24 months. This facility commenced commercial
production in November 2004.
At the end of the expansion project in 2007, BHL had ten sugar
manufacturing locations across UP with a cane crushing capacity of 96,000
tcd and was also the country’s largest ethanol producer with an output of
480 KL/ day.
In an acquisition move, the Company took over the Pratappur Sugar and
Industries Limited (PSIL), district Deoria, Eastern UP in December 2005.
This Plant, in operation since 1903, had a crushing capacity of 3,200 tcd,
which was increased to 6,000 tcd in the subsequent sugar season 2006-07.
PSIL was subsequently renamed Bajaj Hindusthan Sugar and Industries
Limited (BHSIL) and became a subsidiary of BHL. This acquisition
provided BHL a strategic foothold in the sugar-deficient region of Eastern
UP and reaffirmed the consolidation that took place in the sugar industry.
the capacity to manufacture 160 kilo-litre per day of ethanol. The total
BHSIL embarked upon significant new expansions. While the capacity of
its existing sugar plant at Pratappur was enhanced, three new sugar units
were also set up in virgin, cane-rich areas of East UP at Rudauli (district
Basti), Kundarkhi (district Gonda) and in Utraula (district Balrampur).
BHSIL then, had a crushing capacity of 40,000 tcd and a distillery with
industrial alcohol/ ethanol capacity of the Company, including its
subsidiary, was 800 KL/ day.
With the commissioning of three bagasse-based power co-generation plants
at Kundarkhi, Rudauli and Utraula, BHSIL had an aggregate power
generation capacity of 95.8 MW. Combined with the power generation
capacity of 325 MW from BHL, the Company’s total generation capacity is
420.8 MW. After meeting its own energy needs, the Company has a surplus
of 90 MW. It supplies a significant part of this surplus power to the UP state
grid.
In December 2010, BHSIL was amalgamated with BHL.
The Company’s growth initiative has been led by a strategic focus of
attaining global scales of manufacturing and cost competitiveness. Such
benchmarking provides BHL advantages of cost and higher domestic
market share where demand is expected to outstrip supply for the next few
years.
BHL is in a unique position. While its planning and processes are
benchmarked against global practices, its activities are directed at
contributing to the Indian rural economy at a local, grassroots level,
primarily in the uplifting of the farmers. The Company embarked on an
expansion, the scales of which are unprecedented worldwide, providing
tremendous opportunities of employment, infrastructure and community
development and contributing to the growth of the rural economy of UP.
Sugarcane, is broadly classified into three varieties early, general and
unapproved. Cane is sowed during February and October every year. The
first seed growth is known as the plant and subsequent growth after
harvesting from the stem is known as Ratoon. The early variety has more
sugar content than the general variety.
Every farmer within the command area of the Mill is provided with a
calendar, which tells him when he can expect a Mill Supply Ticket
(Purchy), against which he will deliver the sugarcane.
He then harvests the cane and transports it either in a bullock cart or tractor
trolley to the mill. Cane is also bought at the mill's own centers within the
command area. This cane is then transported in trucks or through 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 through mills. Each
mill consists of three rollers:
1. 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
2. This juice is heated and then treated with milk of lime and sulphur
dioxide. The treated juice is then further heated and sent to clarifiers
for continuous settling. The settled mud is filtered by vacuum filters
and filtered juice is returned to be further processed while the oliver
cake is sent out
3. The clear juice is evaporated to a syrup stage, bleached by sulphur
dioxide and then sent to vacuum pans for further concentration and
sugar grain formation. Crystals are developed to a desired size and
the crystallized mass is then dropped in the crystallizers to exhaust
the mother liquor of its sugar as much as possible. This is then
centrifuged for separating the crystals from molasses. The molasses
is re-boiled for further crystallization
Thus, the original syrup is desugarised progressively (normally three times)
till finally, a viscous liquid is obtained from which sugar can no longer be
recovered economically. This liquid, which is called final molasses, is sent
to the distillery for making alcohol.
The sugar thus is separated from molasses in the centrifuge is dried, bagged
(50 Kg and 100 Kg), weighed and sent to storage houses.
Sugar is made in different sizes and accordingly classified into various
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 respective state
government polices. 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, fibre 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 on State Electric Boards, for their power supply 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.
Bajaj Bhu Mahashakti
Soil fertility is seriously impaired with the excessive use of chemical
fertilizers. Research conducted to study the fall in grain production indicates
that the soil is getting drained of organic carbon because of over use of
fertilizers, thus effecting soil fertility.
The gainful use of bio-manure can help address this threat. ‘Bajaj Bhu
Mahashakti’ is a plentiful source of carbon for the soil besides being rich in
NPK(Nitrogen-Phosphorus-Potassium). The use of Bhu Mahashakti
balances the soil organic carbon in the soil and thereby preserves optimum
productivity and soil fertility.
Bhu Mahashakti (Bio-compost)
“Bajaj Bhu Mahashakti” Bio-manure / Bio-compost is manufactured by
composting press mud received from cane juice filtration and spent wash
received from distilleries.
Composting Process
Composting is the biological decomposition of ligno-celluloid
organic material into a simple compound, a humus-like end-product
called “compost”. It is a rich source of organic manure. It also helps
significantly improve the quality of the soil.
The process is aerobic which uses various micro-organisms such as
bacteria, actinomycetes and fungi to break down the higher organic
compounds, like cellulose and lignins, into simpler substances.
During composting, the micro-organisms consume oxygen while
feeding on organic matter, and multiply. Active composting
generates a considerable amount of heat. It also discharges large
quantities of carbon dioxide and water vapour into the atmosphere.
The loss of carbon-dioxide and water vapour reduces the weight of
the initial dry organic matter. Thus composting reduces both the
volume and the mass of the organic matter.
Process of Bio manure Formation
Press mud is stored in triangular shaped rows known as windrows.
Spent wash is sprayed on each windrow at specific intervals. The
windrows are then turned.
This helps in homogenising the entire mass, maintaining uniform
temperature and moisture with effective aeration and oxygen supply.
During the composting process, the temperature goes up to 650-700
C
Due to the churning of the mixture of press mud and spent wash by
aero tillers, oxygen is supplied to bacteria, thereby accelerating the
composting process. It also dissipates the excess heat generated.
Bacteria separate carbon and other complex compounds from press
mud and spent wash.
Enhancing the effectiveness of this process requires 50-60%
moisture.
Composting Cycle
It takes typically 60 days to complete the composting cycle. During
the first five days windrow dressing, moisture reduction and
inoculation are completed. From the sixth to the 50th day, the
temperature and moisture levels are maintained by spraying spent
wash. From the 51st to the 60th day, moisture reduces curing and
aging, and the stabilisation process gets under way. This again
reduces the moisture level.

The quality of the sugar manufactured at bajaj hindusthan ltd. is controlled by:-
1. Maintaining process parameters strictly e.g. ph of juice, temperature of mixed
juice and syrup juice
2. Maintaining good sanitation at mills and in the boiling house
3. Using minimum, tested, good quality chemicals for processes
4. Adopting latest technologies for juice and syrup/melt clarification e.g. film type
sulphur burner, SCS, FCS and MCS
5. Avoiding direct steam application to intermediate sugar products
6. Doing experiments and special analysis to ensure optimum ICUMSA of all
intermediate products and the final product
At bajaj hindusthan ltd. We produce sugar of following grades:-
L-31, M-31, S-31, L-30, M-30 and S-30 out of which maximum
production is of 31 colour sugar. (31 is the best colour standard
fixed by the Government of India)
Sugar grading is done for colour and grain size. Sugar produced is
regularly matched with N.S.I. standards
Percentage retention of sugar is currently being maintained at 85%+
as against minimum requirement of 70%
Every year bajaj hindusthan ltd. conducts a survey of its command area to bring on
record the cane cultivated area of the farmers. This also takes care of the different
varieties of sugarcane that are grown by farmers.
Post this massive exercise, every farmer within the command area of the mill is provided
with a calendar, which tells him when he can expect a Mill Supply Ticket (Purchy) against
which he will supply the cane.
The calendar is distributed over 180 days. Based on the maturity and recovery expected
from the varieties, the distribution takes place in the calendar.
After receiving the purchy, the farmer harvests the cane and transports it either in a
bullock cart or tractor trolley to the mill gate. Farmers who stay in far flung areas supply
cane at the mill's centers. This cane is then transported in trucks or through rail to the mill.
bajaj hindusthan ltd., has a total of 1,41,155 hectares of culturable land under their
command area. This area covers 1,344 villages and has over 95 centres. It purchases cane
from over 1,13,577 farmers. Assuming a family of 5 per household the economy of over
half a million households is dependent on bajaj hindusthan ltd.
