3. Origin of HNL
• This Project was
conceived, as early as, in
1968
• Feasibility Report was
prepared
• GoI took the decision in
May, 1970 to approve
this Project in principle
• In 1983, Kerala
Newsprint Project
commenced commercial
operations
• The Indian government
directed HPC to promote
and incorporate as a
government company.
• Under the Companies Act,
1956, took over and operate
the said Newsprint Mill and
to acquire all the properties
and assets as well as all the
debts and liabilities
belonging to the Newsprint
Mill.
• HPC promoted and
incorporated Hindustan
Newsprint Limited (HNL) as
its fully owned Subsidiary

4. Products & Product History
• Newsprint is used in the printing of newspapers, flyers, and other
printed material intended for mass distribution.
• Diversity in range
– Initially, the company produced 52 GSM (Grams per Square Meter)
newsprint.
– Later commenced production of 48.8 GSM newsprint & 45 GSM
newsprint.
– Colour Standard / Pink, Brightness 55 - 58 %, ISO Size of reel 34 cm to
163 cm
• At the time of commissioning in 1982, newsprint had 48-50 %
ISO brightness.
– Later, it adopted a superior and eco-friendly technology in bleaching
using Hydrogen Peroxide (H202).
– Enhanced the brightness to 53-55% ISO.
– further advanced the brightness levels and is at present producing
newsprint with 55 - 58 % ISO. 4

5. Purchase at Gate
• The Purchase at Gate scheme was launched
by HNL as a complementary, programmed to
Farm Forestry scheme. As per this scheme,
pulp wood materials are purchased directly
from farmers at a remunerative price at the
company gate doing away with middlemen.
• Highlights of the HNL Purchase at Gate Scheme:
• Launched in the year 1998.
• Direct purchase of raw materials from farmers.
• Farmers can bring in pulp wood directly to HNL gate and collect the
price immediately.
• No middlemen involved – farmers get fair price for their produce.
• Swings in the market do not affect the farmers as the demand from5

6. Wood used ….
• Pulpwood like Eucalyptus, Acacia, Mangium
etc have found an alternative market as they
are being purchased by plywood Industries
paying a very high price, this made to use
Tissue Culture bamboo

7. Technology Highlights
• Continuous up-gradation and improvisation in
technology for cost minimization and quality
improvements.
• First Newsprint Manufacturer in India to integrate
process automation covering all the plants.
• E-practices in all functional areas viz. purchase,
distribution, finance, stores, HR, process and
maintenance.
• Online Digital quality control system.
• Incremental, significant technological
improvements in all critical areas. 7

8. • Use of Hydrogen Peroxide for bleaching.
• Installed and later upgraded the computer based
Quality Control System for Paper machine.
• FBC conversion of Boilers.
• Introduction of Distribution Control System for all mill
process operations.
• Lime sludge re-burning plant for recovery of chemicals.
• Energy efficient Falling Film Evaporator and Finisher in
Recovery plant.
• Installed Fibre Optic LAN for mill-wide Computer
networking.
• Implemented Enterprise Resource Planning (ERP)
software. 8

11. Production Capacity
• HNL is one of the well performing PSUs in
the State which is continuously registering
profits since 1990.
11

Production 10,8005 MT
Sales 87,476 MT
Sales Turnover Rs 297.67 Cr
Profit Before Tax Rs 21 Cr
Profit After Current

12. Process
• Three grades of pulp:- Chemi Mechanical pulp,
Chemical pulp and De-inked pulp are blended to
manufacture newsprint.
12

13. Chemi Mechanical Pulp (CMP)
• CMP plant (Sunds Defibrator, Sweden)
• Uses hard wood(Eucalyptus , Acacia) chips to produce pulp.
• Chips are washed, pre-steamed and impregnated with caustic
soda.
• Impregnated chips is mechanically pulped using three
Raffinators.
• Raffinators are driven by synchronous motors of 6.5 MW
(BHEL make).
• Spent chemicals are removed after primary refining using
Twin roll press.
• Pulp after second stage refining is washed and bleached by
Hydrogen Peroxide.
• Bleached pulp after refining is sent to High Density storage
tower for onward use in paper machine. 13

14. Chemical Pulping (CP)
• Capacity of CP plant is 100 MT/day.
• Reed/ Bamboo chips are pulped using
conventional KRAFT.(Sodium Peroxide+ Sodium
Sulphide)
• After counter current washing, pulp is bleached
using chlorine followed by Hydrogen Peroxide stage.
14

15. De-Inking Plant (DIP)
• Uses Old Newspaper and Old Magazine Paper.
• Waste paper is weighed and pulped in Batch Pulper
and stored in Dump Tower.
• Pulp is cleaned off the contaminants using HD
cleaner.
• A seven cell floatation process removes the ink
from pulp.
15

16. • Pulp is then bleached using Sodium Hydro-
Sulphite and stored in High Density storage
tower.
• A Reject handling system separates the rejects
for disposal at about 50% dryness.
• The sludge handling system thickens the ink
sludge to 40% dryness for use in our FBC
Boilers.
16

17. Making of Paper
• The CMP, CP and DIP are mixed in a
definite ratio and chemical additives are
added.
• The paper machine approach flow
system consists of four-stage centri-
cleaner, primary fan pump and a variable
speed secondary fan pump and pressure
screens.
17

18. • The paper machine is the modern high speed
machine from VOITH, Germany.
• With the desired velocity, the diluted pulp flows
from a high turbulance W-type head box into
Duoformer twin-wire forming section.
• The paper web is formed in Duoformer and it is
pressed to remove water with swimming rolls.
• The paper from the press section passes on to a
dryer section, with 36 dryers and one sweat dryer,
having thermo-compressor steam and condensate
system.
• The dried paper surface is smoothened through a
four roll stack. 18

19. • The machine is designed for 750 meters per minute
(mpm) speed with a deckle (width) of 6.85 meters
to produce 44 to 54 GSM newsprint.
• The machine has a sectional D.C. drive with
thyristor control.
• The finishing line has a VOITH winder, Jagenberg
Salvage winder and Klienewefers roll wrapping
machine. Paper core is made here in a spiral core
making machine with purchased kraft paper and
grey board.
19

20. The Utilities
• The steam requirement is met by 3 boilers with
fluidised bed burning.
• There is a chemical recovery boiler of BHEL make.
• There are two turbo generators with capacity of 15
MW and 7 MW.
• Only 35% of total power requirement is met
through State Electricity Board.
• The mill has an effective water and air supply
system for plant use and controls.
20

21. Pollution Control
• Unfailing attention on control measures and constant
monitoring on the results
• Air pollution - Fully functional electrostatic precipitators
for all the boilers and lime kiln.
• Water pollution - Fully equipped effluent treatment
plant. Quality of effluent discharge meets with all the
norms specified statutory regulations / guidelines.
• Land pollution - Construction of a secured land fill
facility for hazardous waste disposal.
• Integrated process automation covering all the plants-
First Newsprint Industry in India to implement the
same.
• E-practices in all functional areas viz. purchase,
distribution, finance,stores,HR,process and
maintenance 21

22. Effluent Treatment
• In keeping with National priorities and increasing
social obligations, HNL is ISO 14001 certified and
has adopted environmental and pollution control
measures.
• The colour and other pollutants are removed and
water free from pollutants is discharged into the
river.
• Air pollution is also controlled by effective Electro
Static Precipitators.

 HNL has bagged the Kerala State Pollution Control awards in 1997-
98, 1999-2000 and 2002 for the best pollution control measures and
processes adopted in the mill.
 A survey of the Indian Pulp and Paper Industry, the first-ever "Green
Rating" exercise in the country by the Centre for Science and
Environment (CSE) and supported by the Union Ministry of
Environment and Forest and the United Nations Development
Program (UNDP) has rated HNL among the first five environment
friendly paper mills.
24

25. CONCLUSION
HNL is the only mill in the country, which, in addition to
meeting all parameters for effluent treatment, de-
colourizers the effluent before discharge
HNL is also the first to substitute 90% of chlorine in
bleaching with environment friendly
Recycling , have helped to preserves forest materials
from about 10,000 Ha. of land.
Implementation of farm forestry with the active
participation of Voluntary / Non Governmental
Organizations ((NGOs)
