BALLARPUR INDUSTRIES LIMITED, popularly known as BILT is ‘efficiently managed’, ‘financially sound’, and ‘self sufficient’ and ‘self made ‘ company is
The flagship of the coveted THAPAR GROUPS.

The Thapar Group is one of the leading business houses in India. It has a turn over of Rest 5000/- Cores; BILT is one of the leading companies with in the Thapar Group.

The Thapar Group has a wide range of activities like paper, engineering, electronics, textiles, chemicals, glass, telecommunications, biotechnology, leather etc.

There are 54 companies and 84 plants under this group. Some of the main companies under this group are Crompton Greaves, K.C.T & Bros. Limited, JCT Limited, BILT.

Ballarpur Industries Ltd. (BILT) promoted by LM Thapar, is the leader in Indian paper industry with an annual production capacity of 460000 MT spread over in five manufacturing facilities produces ordinary and superior varieties of writing, printing and specialty papers etc. The company is also backwardly integrated with its Caustisoda/Chlorine manufacturing facility, which is a vital material consumed in the production process of paper.

BILT, which is originally incorporated in 1945 as Ballarpur Straw Board Mills, has changed its name in March 1946 to Ballarpur Paper and Straw Board Mills and again it was changed to the present name in Oct. 1975. Since then the company has grown to be a leader in paper industry by continuous expansion and modernization of its capacity and plant and strategic acquisitions. In 1969 the company has merged Shree Gopal Paper Mills with itself and the company which has acquired the Sinar Mass Pulp and Paper (India) Ltd. (now BILT Graphic Papers Ltd.)
The company which was one of the most diversified companies in the pre-liberalization era of industrial licensing with interests in Paper, Chemicals has decided to focus on its core competence that is in paper and exit from its non-core businesses. First major steps on these lines were initiated in the year 1994-95 with hiving off the glass business. Thereafter the company sold its vanaspati and edible oils business in 1996-97. And in 1998, the chemical division of the company with its plant at Karwar, Karnataka and which has interests in Phosphates, Chlor Alkali and Bromine and Bromine Chemicals was spun of into a separate company that is Ballarpur Chemicals Ltd (now Solaris ChemTech Ltd). To complement its Restructuring and to enable it to emerge as a stronger and more competitive organization, the company is implementing a project and implimentation involving modernization and expansion of capacity at its Units in Shree gopal, Ballarpur and Sewa by 105000 TPA. The Project will be implemented in two phases.
In the first phase, the capacity expansion of 35000 TPA and 28000 TPA is planned over a two-year period from 2000-01 to 2002-03 for Units Sewa and Shree Gopal. In the second phase 42000 TPA of capacity is expected to come on stream at Unit Ballarpur by 2003-04. During the year 2001-02, the company has completed the up gradation of pulp mill at unit Sewa resulting in increase in capacity by 37 tones from the earlier 125 tones of unbleached pulp per day. The company has also completed the installation of a 2.4 meter wide blade coater at Unit Shree Gopal in FY2001-02. BILT entered into strategic alliance with Hansol of South Korea to provide world class blade coated paper to the Indian customer. it is the first company in the world to commercially exploit the fractionation of bamboo and has applied for the world patent for this process. It has also entered into direct retail distribution with the launch of A4 size, 100-sheet pack of Royal Executive Bond
Mr. Gautam Thapar, Managing Director of BILT, has been associated with BILT since 1986 when joined the company as Shop floor Management Apprentice-Paper Mills and was instrumental in turning around BILT in the late 1990s.



In the Power House, electric power is generated to meet the demand of electrical energy for running the plant. The powerhouse can be divided into the following main sections:-
1. Water Treatment Plant (D.M Plant)
2. Coal fired boilers section
3. Recovery boilers section
4. Turbines section
The detailed description of these sections is as follows: -

1,Water Treatment Plant:
In this plant, water is purified so as to make it usable for the boilers. The water, which comes from the pump house, has the hardness of approximately 200-250 and conductivity around 300-600 µ mho. This water with the help of feed pumps is fed to the reaction tank where it reacts with lime to remove the hardness of water. The reaction-taking place is: -
Ca (HCO3) 2 + Ca (OH) 2 → CaCO3 + H2O
Precipitates settle down and water is collected from overflow in some adjacent tank. Now, the water is sent to the pressure filter, where calcium carbonate is taken as filter medium. After pressure filter, the hardness of water decreases to 50-60. Now, this water is passed through the cation exchanger. In the cation exchanger, cationic impurities are removed. Cationic exchanger is charged with HCL every twenty-four hours. Then, the water flows to the De-gasser. Here, water is showered from the upper side and air is pumped from downwards. When the air strikes with water droplets, it takes the gas along with it. After this, the water goes to the weak Base Anion Exchanger, where strong anionic impurities are removed. The next is the Primary mixed bed, where the remaining cationic ND anionic impurities are removed. This water is now stored in the D.M tank. The condensates of steam are also brought to the same tank after passing through charcoal and iron filters. To ensure the required standard of de-mineralized water, the water is taken to the secondary mixed bed. Ammonia is dozed in this water so as to increase the pH to about 6.8-6.9. Now, this water is sent to the boilers for steam production.

2.Boiler section: -
The boiler section has two main parts: -
1. Coal fired boilers
2. Recovery boilers

The new transistor achieves a record high-switching performance which will make our future electronic devices - such as PDAs and computers - even more functional and high-performance.
In a paper to be published in Electronics Letters on 3 February 2011, Dr Zakaria Moktadir of the Nano research group at the University's School of Electronics and Computer Science (ECS) describes how his research into graphene, a material made from a single atomic layer of carbon, arranged in a two-dimensional honeycomb structure, led to the development of graphene field effect transistors (GFETs) with a unique channel structure at nanoscale.
According to Dr Moktadir, in the context of electronics, graphene could potentially replace or at least be used side by side with silicon integrations.
"CMOS (Silicon Complementary Metal-Oxide- Semiconductor) downscaling is reaching its limits and we need to find a suitable alternative," he said. "Other researchers had looked at graphene as a possibility, but found that one of the drawbacks was that graphene's intrinsic physical properties make it difficult to turn off the current flow."
