CHAPTER 1.0:-INTRODUCTION
1.1 PROJECT BACKGROUND
M/s. Century Plyboards (I) Limited (CPIL) has proposed to set-up synthetic resin
manufacturing unit within the existing ply board plant located at survey No. 145, 147
Paiky and 148, Village Motichirai, Bhachau Road, Gandhidham, District Kutch in
Gujarat State.
Plywood industries are the main users of synthetic resins. Its invention in early 19th
century brought revolutionary change in industrial field. Various types of resins are
being produced by addition or condensation polymerization of alcohols, phenols,
Aldehydes, amines, carboxylic acid etc. and are being used in various industrial and
engineering activities. Resin’s application largely depends on nature of the products.
Most commonly used resins are Urea Formaldehyde Resin, Phenolic Resin,
Melamine Resin and their derivatives.
1.2 IDENTIFICATION OF PROJECT AND PROJECT PROPONENT
The CPIL's products range includes almost all the varieties of plywoods, such as
commercial plywood, boiling water-proof plywood, decorative plywood, shuttering
plywood, block board, film face plywood etc.
After two years of rigorous R&D in the year 1998, Century introduced 100 percent
termite and borer proof plywood with 7 years comprehensive warranty and launched
the new product in the market with wide publicity and thereafter within a few months
it became the top selling brand of plywood in the country. As on date the borer proof
decorative plywood introduced by Century has become the minimum bench mark in
the plywood industry. Thereafter with the help of IPIRTI, Century undertook another
R&D project that is of making 100 per cent boiling water-proof decorative plywood.
So far decorative plywood was available without boiling water proof due to various
constraints in manufacturing the same. Century successfully concluded its R&D and
made a new mark with another innovative product i.e. 100 per cent boiling waterproof
decorative plywood - almost at the same price being charged by its competitors for
general products.
Since the last few years, CPIL is maintaining an annual growth of approximately 40
percent and has already reached No.1 status in the Indian Plywood Market and
selling more than everybody and atleast 30 per cent more than its immediate rivals
CPIL was incorporated on 5th January, 1982 as a private limited company. With effect
from company is having its registered and head office at Kolkata. CPIL is promoted
by Shri B. L. Agarwal, Shri H. P. Agarwal, Shri Sajjan Bhajanka and Shri Sanjay
Agarwal who are experienced and well-known businessmen.
In 1986, CPIL set up a unit at Bishnupur, 24 Parganas (S), West Bengal to
manufacture Plywood and Veneer with an initial installed capacity of 5000 CBM and
Page | 5
12500 CBM per annum respectively, gradually, the installed capacity of the unit has
been increased to 25200 CBM and 50400 CBM respectively for plywood and veneer.

1.3 BRIEF DESCRIPTION OF THE PROJECT
The Century Plyboards (I) Limited (Kandla Unit) started ply board plant in 2013.
Being inspired by the growth and demand of synthetic resin, CPIL proposed to set up
resin manufacturing plant with 12000 TPA capacity within the existing plant CPIL
plant at Kandla.
The proposed synthetic resin manufacturing plant of CPIL, Kandla, comes under Sr.
No. 5 (f) of EIA Notification, 14th September 2006 and subsequent amendments 25th
June 2014 SO 1599 (E) of Ministry of Environment, Forests and Climate Change
(MoEF&CC). The Proposed synthetic resin manufacturing plant of CPIL, Kandla is
falls in Category ‘B’ and requires Environmental Clearance from State
Environmental Impact Assessment Authority (SEIAA) of Gujarat State.
The proposed production capacities of the proposed plant are given in Table 1:

1.4 NEED OF THE PROJECT & ITS IMPORTANCE TO THE COUNTRY AND OR
REGION
The wood and paper-based industry, that includes plywood, laminates and other
paneling materials clocked estimated revenues of Rs.12,000 Crores in 2011-12. Up
from Rs. 8,000 Crores in 2007-08, this 15% compounded growth has come at the
back of rising per capita income, demand for premium housing, office and
commercial space, and a boom in hospitality and healthcare sectors.
The industry is highly fragmented, with a major chunk of production coming from
small manufacturers, many of whom do not even possess a license to produce.
However, the market is driven by a few large companies who have plants at multiple
locations, invest heavily in brand building, offer ISI-marked products, and constitute
around 30% of the industry revenue.
Some of the bigger plywood companies in India and the brand names of their
plywood are listed (in random order) in the Table 2.

National Plywood Industries Ltd.
Brand name: 'National plywood'
The company manufactures plywood as well as laminates.
Sarda Plywood Industries Ltd.
DuroPly, DuroFlex, Duro-PumaPly as well as several other brands.
The company manufactures plywood, decorative plywood, block boards and flush doors etc.
Mayur Plywood Mayur ply The company has a Pan-India presence and also makes decorative plywood, veneers and doors.
The related products such as laminates, block boards and flush doors are also sold by most of the companies. Many of the bigger companies have also now ventured into the ready-made furniture market in India, as well as into the manufacture of newer engineered wood products such as Prelaminated Particle boards and MDF (Medium Density Fibre boards). The Indian market for particle board and plywood is estimated in value terms, at over Rs 17 billion. Of the total market, particle board accounts for over 30% of the market with the rest over 70% accounted by plywood segments. It is roughly presumed that the total size of Indian Plywood Market is around Rs.5000 Crores in value terms and around Rs 60 Crores sqm of plywood on 4mm basis in quantity terms. The market is divided between two categories i.e. (1) branded products and (2) non-branded products. Until 1970 the share of branded products was 90% in comparison to 10% of non-branded products but now the situation has been almost reversed and the branded products have only 10 per cent market share. Generally branded products are being manufactured by the plywood factories in the medium scale, who are paying all the taxes and excise duty, whereas non-branded products are mostly being manufactured by SSI units, most of whom are availing
Page | 8
excise and sales tax exemptions. These SSI units generally are not fully integrated ones. They buy semi-processed raw material and do the pressing and finishing jobs in their factories. Thus excise duty collection is largely from the branded products. The total duty collection from plywood industry is estimated to be Rs.70 crores, out of which Century's contribution is likely to be more than Rs.7 crores i.e. around 10 percent of the total excise collection in the country from the plywood industry. When the excise contribution of Century is compared with other branded plywood manufacturers, Century is the highest excise contributor and the next contributor is 30 to 40 percent below it, followed by further lower contributors. In the western and southern markets, Century is the No. 1 selling brand, whereas in other markets it is among the top three. The company has achieved a considerable growth in turnover by 36 per cent in the year 1997-98, 48 per cent in 1998-99 and 52 percent in 1999 -2000. It has achieved a turnover of Rs.116 Crores during 2000-01 resulting in a growth of 20 percent.
1.5 DEMAND & SUPPLY
Plywood is made by glueing several layers of wood veneer (thin sheets of wood) over
each other with the grain pattern alternating at right angles in every subsequent
layer. During the plywood manufacturing process, the individual layers of veneer are
first obtained by rotary-cutting a log. For this the timber logs are rotated about their
longitudinal axis, while a cutter peels the log at the set thickness (each layer is
usually less than 2.5 mm in thickness). Later on, adhesives are spread on these
veneers using a glue-spreader machine. The machine helps in achieving a uniform
glue spread.
Demand of synthetic resins in the country is increasing day by day. These resins are
industrial additives used as bonding materials in plywood industries for
manufacturing of plywood, veneer sheets, particle board (composite wood core with
plastic laminate finish), panel products (fiber board), plywood made from both hard
and softwood (veneered panels and laminated woods), and medium density fiber
board etc. These resins are one of the most versatile chemicals and are a basic
building block to many important industries. The growth and demand of the ply board
largely play an important role for the growth and demand of synthetic resins. Since
last 2-3 years the Plywood, Laminate, Fabric items, Steel Industries and Engineering
products are growing at a remarkable space, which in turn increased the demand of
various industrial inputs. The market demand of synthetic resins is also filling the
upward growth tendency living a scope for further investments in these sectors,
especially because the existing capacities may not be sufficient to meet the new
demand. Some of the existing manufacturer of synthetic resins is in this line over a
long period and their plant capacities are at optimum level of utilization. Moreover,
the recently invented process technology for better quality product also needs further
investments and shall open new markets.
Since all the existing manufacturers are not in organized sector, country’s total
installed capacities vis-a-vis production for last few years are difficult to procure.
However, from the market trends the upward rise in demand of the product is being
felt by most of the manufacturers. The annual growth of steel, foundry, casting,
Page | 9
laminate and plywood industries supports this upward trend in demand of synthetic
resins. Demand for resin is related to overall growth of other industries like ply
woods, particle board, laminates, housing, furniture, consumable durables, shipping
and railway sector.
1.6 EMPLOYMENT GENERATION (D IRECT AND INDIRECT) DUE TO THE PROJECT
The total requirement of manpower for the proposed resin manufacturing plant is
estimated at around 50 numbers. The required manpower is available locally.
Specialized training required for plant operation and maintenance will be carried out
by skilled personnel.

for industrial use.
2.5 PROCESS DESCRIPTION
The proposed synthetic resins manufacturing processes are summarized below:
2.5.1 MANUFACTURING OF PHENOL FORMALDEHYDE (PF) RESIN
It includes synthetic thermosetting resins obtained by the reaction of Phenol with
Formaldehyde. Phenol Formaldehyde Resin, as a group, is formed by a step - growth
polymerization reaction that can be either acid or base - catalyzed. Since
formaldehyde exists predominantly in solution as a dynamic equilibrium of Methylene
Glycol Oligomers, the concentration of the reactive form of formaldehyde depends on
temperature and pH.
Formation and structure:
Phenolic Resin is reaction products of phenol and/or substituted phenol with
formaldehyde. An unlimited variety of resin is possible depending on (1) the choice
Page | 13
of phenols, (2) the phenol: formaldehyde molar ratio, (3) the type and amount of
catalyst used, and (4) the time and temperature of reaction.
The active positions on the phenol molecule are the two ortho and one para
positions. When more than one mole of formaldehyde is reacted with one mole of
phenol in the presence of an alkaline catalyst, the following initial products can be
formed:
Further heating of these initial reaction products results in condensation and an
increase in molecular weight. Condensation takes place between two methylol
groups to form a methylene ether link (a) or between a methylol group and an
active ortho or para hydrogen atom to yield a methylene link (b).
The amount of heating determines the final form of the product, e.g., whether the
resin is a low viscosity, water-soluble liquid, a higher viscosity liquid with little or no
water miscibility, or a grindable solid. Highly viscous forms may be dissolved in
solvent after the resin has been dehydrated. If the reaction is carried too far, the
resole can gel. Therefore the reaction is always conducted under carefully
controlled conditions of time, temperature, pH, and mole ratio of formaldehyde to
phenol.
Being thermostes, hydroxymethyl phenols will crosslink on heating to around
120°C to form methylene and methyl ether bridges. At this point the resin is a 3 -
dimensional network, which is typical of polymerized phenolic resins. The high
crosslinking gives this type of phenolic resin its hardness, good thermal stability,
and chemical imperviousness.
Manufacturing Process:
A typical phenolic resin is made by a batch process in a jacketed, stainless steel
reaction kettle, equipped with turbine-blade or anchor type agitator and condenser.
Molten phenol and formalin (37 – 40% formaldehyde) is charged to the kettle and
agitation begun.
To make a resole resin, an alkaline catalyst such as sodium hydroxide is added to
the phenol and formaldehyde before heating the batch to 80-100ºC. Reaction
temperatures below 100˚C are controlled with vacuum.
Page | 14
Reaction times are generally 1-3 hr. Since a resole resin is capable of gelling in the
still, dehydration temperatures are kept below 105ºC by the application of vacuum.
Gel time on a 150ºC hot plate is a common test that is used to indicate the degree
of advancement of the resin and to determine when the batch should be
discharged.
Solid resoles are discharged to resin coolers, a series of parallel, internally cooled
metal plates that the resin flows between to be rapidly cooled.
The low molecular weight, water soluble resins are finished at as low a
temperature as possible, usually around 50ºC, whereas the less reactive para-
substituted resoles can be finished at temperatures as high as 120ºC.

2.5.2 MANUFACTURING OF UREA FORMALDEHYDE (UF) RESIN
Urea formaldehyde resins are poly - condensation products of the reaction of
formaldehyde with urea. The relatively easy production of the UF resins, their good
solubility in water and absence of colour, make these thermosetting polymers
irreplaceable in the manufacture of many wood based products. Due to the UF resins
low resistance to humidity the panels obtain are suitable for interior use in dry
condition. The specifications of the resin product such as the molar ratio of
formaldehyde to urea, solids content, viscosity, reactivity etc. are adjusted in order to
meet any customer requirement.
Urea formaldehyde resin is prepared by reacting urea with formaldehyde in a
molar ratio of 1:1.8 generally. Urea reacts with formaldehyde under neutral or
alkaline condition to yield monomethylol urea, symmetrical dimethylol urea and
trimethylol urea depending on the ratio of the reactants.
The resinification process for urea formaldehyde occurs in two main stages,
addition or methylolation and condensation.
In the methylolation step, urea and formaldehyde are reacted under controlled
conditions using an alkaline catalyst. Typically, the methylolation step is carried
out at a pH of about 8.0. The methylolation stage usually results in a mixture of
methylolated species, monomethylol urea, and dimethylol urea and trimethylol
urea.
Page | 17
This mono and dimethylol urea may be regarded as the monomer of the urea-
formaldehyde resin.
In the second stage these methylol urea undergo condensation to form low
molecular weight polymers. The rate of reaction depends on pH. Acid catalyses the
reaction in many ways:
Formation of Methylene Bridge in amino nitrogen facilities in acidic medium.
Methylene ether linkages also can be formed in acidic medium.
Two types of acid materials can be used, which are classified as (1) direct catalysts
& (2) latent catalysts.
Direct catalysts are inorganic and organic acids, acid salts. They are effective at all
temperatures. The latent catalysts are salts and esters which develop acidity upon
heating.
The solution is refluxed at 82-85ºC for about one hour to complete the formation of
Dimethylol – urea.
The condensation reaction proceeds to a predetermined end point, and the resin
intermediate is cooled.
At this stage reaction is arrested by raising the pH of the resin to about 7.0 to 8.0
by adding sodium hydroxide and cooled to ambient temperature by circulating
water in jacket and discharged from the vessel.

Formation and Structure:
Methylol condensation occurs in a major extent. So, -CH2 – O – CH2 & -CH2- both
type linkages are formed.
All the six hydrogen atoms of melamine can be replaced by methylol groups upon
reaction with formaldehyde. However only 2 or 3 methylol groups are usually
introduce for production of thermosetting resin (insoluble and infusible). So in MF
resin preparation melamine and formaldehyde are taken in 1:2 to 1:3 molar ratios.
When melamine formaldehyde ratio crosses above 3 the pH of the reactants in
each step should be strictly maintained.
In the whole preparation, the temperature is controlled very much efficiently.
Because at elevated temperature curing of MF resin becomes very much facile and
occurs in a higher rate and 1st stage resin is prepared at elevated temperature. As
melamine has very poor solubility in water and aqueous formaldehyde at normal
temperature and during the preparation of 2nd stage resin for proper mixing of
compounding ingredients in 1st stage resin the temperature is required to raise to
some extent, at the time of milling temperature of the substance increases
somehow; so at any stage of above two there is a possibility of premature curing if
temperature goes out of control.
The effect of pH is not so great. Though at the time of 1st stage resin preparation
the medium should have neutral or slightly alkaline pH for good yield. But at the
Page | 20
time of curing pH is not required to control in a continuous manner. Curing can
occur at any pH but the rate differs. Generally at pH 10-10.5 the rate of curing is
very slow but an increase or decrease of pH in any extent from this value will give
rise to a healthy rate of curing.
Manufacturing:
In MF resin preparation, melamine and formaldehyde are taken in 1:2 to 1:3 molar
ratio. For water soluble MF resin this ratio is 1:6 to get Hexamethoxymethylol
melamine (HMM).
It is manufactured by reacting melamine with formaldehyde in a jacketed reactor
under neutral or alkaline condition.
In first step melamine reacts with formaldehyde in aqueous solution (37 % w/w) to
form methylol compounds. The reaction is carried out under slightly alkaline
condition.
Since melamine is not soluble in water at room temperature. It is necessary to heat
the mixture to about 85°C for obtaining methylol compounds.
In the preparation of water soluble resins, the solution of methylol compound is
further heated under alkaline condition until the desired viscosity or solubility
characteristics are obtained from increased molecular weight.
Liquid formaldehyde is taken in the reaction vessel and melamine powder is added
slowly with stirring. After about 15 minutes caustic soda solution is added and the
mixture is heated by steam. The temperature is controlled at about 85°C.
Then the product is made alkaline by adding caustic soda solution (20% strength)
and subsequently cooled to room temperature. Finally, it is stored in a storage
barrel.

2.5.4 MANUFACTURING OF MUF RESIN
The MUF resin produced has unique characteristics and properties, which in many
ways are very different from the properties of MF or UF resin. Various MUF resin
formulations have different properties, performance and durability. The important
properties of MUF resin include the shelf life, solubility in water and curing period are
formulated according to its applications. MUF resin formulations are built up from a
combination of several factors. Among the important factors are the reaction period
for each stage, the efficiency of controlling the pH and the temperature throughout
the process, the mole ratio of formaldehyde to urea/melamine and the number of
stages in which amino compound is reacted. The combination and variation of these
factors produce different resin shelf life, degrees of solubility in water and curing
periods.
Manufacturing:
Formaldehyde is taken in a reaction vessel with Urea at pH 8.5 to form Formic
acid. The reaction is done at 60ºC temperature. Then to the mixture melamine
powder is added slowly and the mixture is then stirred well at a temperature of
88-90ºC.
The solution is refluxed at 88-90ºC for about one hour to complete the formation
of resin water (1:6.5). The pH is maintained to 8.5 by addition of caustic and then
addition of PVA.
The condensation reaction proceeds to a predetermined end point, and the resin
intermediate is cooled.
At this stage the product is cooled to ambient temperature (35ºC) by circulating
water in jacket and discharged from the vessel and the product is unloaded.
Total Batch time is about 5 hrs and evaporation loss of about 1%.
