1. INTRODUCTION AND JUSTIFICATION OF THE PROJECT
1.1 Identification of Project
M/s Sheela Foam Limited is currently producing and processing Poly-Urethane Foam (PU
Foam) for various industrial consumers, furniture and bedding applications at Jalpaiguri. The
major foam today is produced at Greater Noida plant and shipped to Jalpaiguri. As a
commitment towards customer, industry and the state, they would like to expand the facility PU-
Foam production from 300TPM to 600TPM at its Jalpaiguri Unit licated at Kanchan Jangha
Integrated Park, P.O - Jhanjupara, P.S - Rajgung, Jalpaiguri, WB- 735134
For the proposed expansion of the PU Foam production, the Project Proponent is willing to
expand the storage of Tolune di isocyanate (TDI) which is one of the raw materials for
production of PU Foam, from less than 10T to 60T. As per the MSHIC Rules 1989, the threshold
Quantity of storage of TDI is 10MT. So as because the proposed storage quantity is exceeding
the threshold limit, the proposed expansion requires the Environmental Clearance
The notification no. S. O. 1533 promulgated on 14th
September 2006 had covered this industry
as Synthetic Organic Chemicals which requires Environmental Clearance (EC) as category ‘A’
project under clause 5 (f) as it is not situated within Notified Industrial Estate .
1.2 Identification of Project Proponent
Sheela Foam Limited is the largest foam and mattress company of India. It has manufacturing
facilities all over India. The Main promoter is Mr. Rahul Gautam, who is also the Managing
Director of the Company. The Company is run by professionals under the guidance of the MD

Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 5
1.3 Need of Project and its Importance
Advancement in science and technology has created so many products that have enhanced the
quality of human life in every passing year. The human race is largely dependent on
industrialization for up gradation in quality of life. Progress of the nation is judged through its
economic growth which is largely dependent on industrial productivity. PU Foam is used in a
large number of strongly diversified applications, such as filler for seats, chairs and seat
cushions, mattress centres, car seats, encapsulation of car windows, shoes and textiles, thermal
insulation (buildings, industrial installations, refrigerators, etc.), sound insulation, adhesives and
paints/coatings, etc. The great advantage of PU foam is its great flexibility in meeting the
various applications and requirements. Polyurethane owns some extremely exceptional material
qualities such as: density, elasticity, durability, weight, safety, design and of course its attractive
price.
Since PUF is mainly used together with other materials, such as textiles, metal, wood and other
polymers, it is not always visible in the end products. Polyurethanes are used throughout cars. In
addition to the foam that makes car seats comfortable, bumpers, interior “headline” ceiling
sections, the car body, spoilers, doors and windows all use polyurethanes. Polyurethane also
enables manufacturers to provide drivers and passengers significantly more automobile
“mileage” by reducing weight and increasing fuel economy, comfort, corrosion resistance,
insulation and sound absorption.
Being a leader in Polyurethane (PU) Foam, Sheela Group is a multi-billion rupee entity. It has a
nationwide presence in manufacturing PU Foam with a global marketing perspective and an
impeccable track record, since 1971. The Company has foaming plants all over India. These are
located in Greater Noida, Talwada, Hyderabad and Erode Further it has mattress making plants
at 6 more locations spread all over India.
With growing complexities in the business and more demanding customers there is a need to
explore setting up more plants at promising locations. For north/east zone, it is decided by the
Company to locate the same at Jalpaiguri. Jalpaiguri is strategically located in chicken neck
portion of India, connecting Northeast seven sisters with rest of the country.
As a commitment towards customer, industry and the state, they would like to expand the
facility to include PU foam production from 300 MT/Month to 600 MT/Month along with curing
and storage.
1.4 Demand Supply Gap:
Polyurethane foam (PU foam) is a very versatile material. Its open and elastic cell structures
make it very resistant to oxidation and aging, especially if compared to rubber or latex foams.
According to the additives and the manufacturing systems used, very different characteristics
and foams for very different uses can be achieved.
Thanks to its diversity, it‟s present in all aspects of daily life. In order to compare the different
foams we usually use the density, but it only serves as a comparative element when we‟re
Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 6
talking about foams with the same composition. Their uses are multiple- the insulation capacity,
the ease of profiling or shaping, the lightness, the rigidity, etc. The sectors that most use this raw
material are:
 Rest area: in mattresses as main filling or as part of quilts.
 Furniture sector: in seats of sofas and chairs, padded fillers, etc.
 Construction sector: as thermal insulation, acoustic absorbent, etc.
 Automotive sector: in dashboards, seats, etc.
 In many toys, sponges, shoes, pillows, clothing, packaging and in general all kind of
fillings and quilting.
Growth of polyurethane foam market can be attributed to increasing demand for polyurethane
foam from bedding & furniture and building & construction end-use industries. Significant
investments in new infrastructure development, new housing projects, and renovation of non-
residential buildings in US, China, India, and Brazil have also influenced the growth of the
polyurethane foam market.
India will consume 1 kg of polyurethane (PU) per capita by 2020 at 1200,000 TPA, as per a
conservative estimate by the Chairman of the Indian Polyurethane Association (IPUA). Current
per capita PU consumption in India is about 200 grams. The 1 kg per capita target will be
possible, depending mainly on easing bureaucracy by the government that will speed up some of
the processes and make it easy to set up factories and help to build infrastructure, as well as
initiatives by the industry. At annual consumption levels of 180,000 tons of Polyurethane (PU)
in 2007, India has just about 1.5% share of the global PU consumption of 11.25 million tons. In
the last few years PU has grown at over 15% pa, and is expected to continue to be robust at an
average rate of 15%. Regionally, polyurethane foam demand is relatively close to production
because trade is not economic over larger distances. The production of flexible foam accounts
for the largest share of the Indian polyurethane industry.
1.5 Import Vs. Indigenous Production
Polyurethane foam is an extensively used polymer and plastic. They are available in two forms
i.e. rigid and flexible foams. Rigid foams are used for various insulation applications pertaining
to refrigeration and construction. It is energy efficient and helps in cutting energy costs. Flexible
foams are used mainly as a cushioning substance in end-use industries such as packaging,
furniture, bedding and transportation.
North America and Europe have been traditionally the dominant consumers of such polymers
owing to relatively stable industrial output. Although, strong economic development in India and
China has shifted the equilibrium and Asia Pacific is expected to emerge as the leading
consumer.
The shift of leading automotive manufacturers to countries such as India and Thailand, Vietnam
and Malaysia from mature economies of North America and Europe has complimented region‟s
industry growth.
Environmental benefits of this product include high recyclability and clean incineration for
pollutant filtration, reduced wastage, and greater sustainability. However, several governments
and federal agencies are increasingly being concerned with detrimental health effects of
isocyanates utilized in PU production.
Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 7
Growing need in automotive components including dashboards, armrests, airbags, other
vehicular components, and exteriors is anticipated to drive consumption. Strengthening
economies, improvements in sovereign balance sheets, and positive demographic outlook,
mainly in Southeast Asian countries such as India, Vietnam, Indonesia, and Thailand are likely
to contribute to high growth in demand.
1.6. Export Potential
There may be large opportunities to become a global supplier of quality PU Foam. Increasing
construction spending in countries such as India, Indonesia, Korea, UAE and Qatar due to strong
industrial sector growth coupled with rising urban population is anticipated to fuel growth in
export market
1.7 Employment Generation:

Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 22
4. RESPONSIBLE CARE FOR WASTES
4.1 Water Regime
Water requirement for the proposed PU Foam manufacturing unit is negligible as no water is
used in the process. Hence, no waste water is likely to be generated during manufacturing
process. No waste water will be discharged outside the plant premises. Therefore, operation of
proposed expansion of assembly unit will not pose any adverse impact on the ground water
resources of the area.
Water Requirement (Domestic & Industrial) & Source accounts to 6 KL and will be sourced
from bore-well installed with water meter.
Facility available for treatment of Waste Water is STP having MBBR Technology with a
capacity of 5.5 KLD.
Domestic waste generated from the toilets is being / will be treated in existing STP & treated
water is being / will be recycled back for gardening and green belt development. Rain water
harvesting is being practiced at plant area. Regular monitoring of water quality is being / will be
carried out.
The STP technology proposed for the expansion is as shown in Figure 4.1.
Fig 4.1: STP Diagram
Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 23
4.1.1.Treatment Process
The STP facility available at the plant uses MBBR Technology with capacity of 5.5 KLD.
MBBR technology employs thousands of polyethylene bio-film carriers operating in mixed
motion within an aerated wastewater treatment basin. Each individual bio-carrier increases
productivity through providing protected surface area to support the growth of heterotrophic and
autotrophic bacteria within its cells. It is this high-density population of bacteria that achieves
high-rate biodegradation within the system, while also offering process reliability and ease of
operation.
This technology provides cost-effective treatment with minimal maintenance since MBBR
processes self-maintain an optimum level of productive bio-film. Additionally, the bio-film
attached to the mobile bio-carriers within the system automatically responds to load fluctuations
4.2 Air Pollution
The unit will have 3 DG sets of 180 KVA, 380 KVA & 45 KVA, which will be kept as a stand-
by and used in case of main power failure. The Diesel will be used as fuel for the DG Set and
adequate stack height of 2.7 m, 3.9 m, 1.3 m will been provided.
4.3 Noise Pollution
The only source of noise generation may be from the D.G. Sets, which will be kept as standby
and no other source of noise and vibration from the proposed manufacturing activity except
Plant machineries. The adequate precautions will be taken for abatement of noise pollutions
All the measures would be taken to limit the noise levels at the plant boundary within 75dB(A)
as per the stipulated limits.
4.4 Waste Management
No solid waste is being generated from the assembly and PU Foam manufacturing process
except scraps. Water requirement for the proposed PU Foam manufacturing unit is negligible as
no water is used in the process. Hence, no waste water is likely to be generated during
manufacturing process.
However „waste foam‟ is generated during cutting process of quantity 3875 Kg/Month, which is
being collected and reused again.
TDI drums will be disposed off to the parties authorized in this regard.

Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 5 1.3 Need of Project and its Importance Advancement in science and technology has created so many products that have enhanced the quality of human life in every passing year. The human race is largely dependent on industrialization for up gradation in quality of life. Progress of the nation is judged through its economic growth which is largely dependent on industrial productivity. PU Foam is used in a large number of strongly diversified applications, such as filler for seats, chairs and seat cushions, mattress centres, car seats, encapsulation of car windows, shoes and textiles, thermal insulation (buildings, industrial installations, refrigerators, etc.), sound insulation, adhesives and paints/coatings, etc. The great advantage of PU foam is its great flexibility in meeting the various applications and requirements. Polyurethane owns some extremely exceptional material qualities such as: density, elasticity, durability, weight, safety, design and of course its attractive price. Since PUF is mainly used together with other materials, such as textiles, metal, wood and other polymers, it is not always visible in the end products. Polyurethanes are used throughout cars. In addition to the foam that makes car seats comfortable, bumpers, interior “headline” ceiling sections, the car body, spoilers, doors and windows all use polyurethanes. Polyurethane also enables manufacturers to provide drivers and passengers significantly more automobile “mileage” by reducing weight and increasing fuel economy, comfort, corrosion resistance, insulation and sound absorption. Being a leader in Polyurethane (PU) Foam, Sheela Group is a multi-billion rupee entity. It has a nationwide presence in manufacturing PU Foam with a global marketing perspective and an impeccable track record, since 1971. The Company has foaming plants all over India. These are located in Greater Noida, Talwada, Hyderabad and Erode Further it has mattress making plants at 6 more locations spread all over India. With growing complexities in the business and more demanding customers there is a need to explore setting up more plants at promising locations. For north/east zone, it is decided by the Company to locate the same at Jalpaiguri. Jalpaiguri is strategically located in chicken neck portion of India, connecting Northeast seven sisters with rest of the country. As a commitment towards customer, industry and the state, they would like to expand the facility to include PU foam production from 300 MT/Month to 600 MT/Month along with curing and storage. 1.4 Demand Supply Gap: Polyurethane foam (PU foam) is a very versatile material. Its open and elastic cell structures make it very resistant to oxidation and aging, especially if compared to rubber or latex foams. According to the additives and the manufacturing systems used, very different characteristics and foams for very different uses can be achieved. Thanks to its diversity, it‟s present in all aspects of daily life. In order to compare the different foams we usually use the density, but it only serves as a comparative element when we‟re
  • 6. Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 6 talking about foams with the same composition. Their uses are multiple- the insulation capacity, the ease of profiling or shaping, the lightness, the rigidity, etc. The sectors that most use this raw material are:  Rest area: in mattresses as main filling or as part of quilts.  Furniture sector: in seats of sofas and chairs, padded fillers, etc.  Construction sector: as thermal insulation, acoustic absorbent, etc.  Automotive sector: in dashboards, seats, etc.  In many toys, sponges, shoes, pillows, clothing, packaging and in general all kind of fillings and quilting. Growth of polyurethane foam market can be attributed to increasing demand for polyurethane foam from bedding & furniture and building & construction end-use industries. Significant investments in new infrastructure development, new housing projects, and renovation of non- residential buildings in US, China, India, and Brazil have also influenced the growth of the polyurethane foam market. India will consume 1 kg of polyurethane (PU) per capita by 2020 at 1200,000 TPA, as per a conservative estimate by the Chairman of the Indian Polyurethane Association (IPUA). Current per capita PU consumption in India is about 200 grams. The 1 kg per capita target will be possible, depending mainly on easing bureaucracy by the government that will speed up some of the processes and make it easy to set up factories and help to build infrastructure, as well as initiatives by the industry. At annual consumption levels of 180,000 tons of Polyurethane (PU) in 2007, India has just about 1.5% share of the global PU consumption of 11.25 million tons. In the last few years PU has grown at over 15% pa, and is expected to continue to be robust at an average rate of 15%. Regionally, polyurethane foam demand is relatively close to production because trade is not economic over larger distances. The production of flexible foam accounts for the largest share of the Indian polyurethane industry. 1.5 Import Vs. Indigenous Production Polyurethane foam is an extensively used polymer and plastic. They are available in two forms i.e. rigid and flexible foams. Rigid foams are used for various insulation applications pertaining to refrigeration and construction. It is energy efficient and helps in cutting energy costs. Flexible foams are used mainly as a cushioning substance in end-use industries such as packaging, furniture, bedding and transportation. North America and Europe have been traditionally the dominant consumers of such polymers owing to relatively stable industrial output. Although, strong economic development in India and China has shifted the equilibrium and Asia Pacific is expected to emerge as the leading consumer. The shift of leading automotive manufacturers to countries such as India and Thailand, Vietnam and Malaysia from mature economies of North America and Europe has complimented region‟s industry growth. Environmental benefits of this product include high recyclability and clean incineration for pollutant filtration, reduced wastage, and greater sustainability. However, several governments and federal agencies are increasingly being concerned with detrimental health effects of isocyanates utilized in PU production.

RESPONSIBLE CARE FOR WASTES 4.1 Water Regime Water requirement for the proposed PU Foam manufacturing unit is negligible as no water is used in the process. Hence, no waste water is likely to be generated during manufacturing process. No waste water will be discharged outside the plant premises. Therefore, operation of proposed expansion of assembly unit will not pose any adverse impact on the ground water resources of the area. Water Requirement (Domestic & Industrial) & Source accounts to 6 KL and will be sourced from bore-well installed with water meter. Facility available for treatment of Waste Water is STP having MBBR Technology with a capacity of 5.5 KLD. Domestic waste generated from the toilets is being / will be treated in existing STP & treated water is being / will be recycled back for gardening and green belt development. Rain water harvesting is being practiced at plant area. Regular monitoring of water quality is being / will be carried out. The STP technology proposed for the expansion is as shown in Figure 4.1. Fig 4.1: STP Diagram
  • 23. Pre-Feasibility Report for proposed expansion of Sheela Foam Ltd, Jalpaiguri Plant Page 23 4.1.1.Treatment Process The STP facility available at the plant uses MBBR Technology with capacity of 5.5 KLD. MBBR technology employs thousands of polyethylene bio-film carriers operating in mixed motion within an aerated wastewater treatment basin. Each individual bio-carrier increases productivity through providing protected surface area to support the growth of heterotrophic and autotrophic bacteria within its cells. It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation. This technology provides cost-effective treatment with minimal maintenance since MBBR processes self-maintain an optimum level of productive bio-film. Additionally, the bio-film attached to the mobile bio-carriers within the system automatically responds to load fluctuations 4.2 Air Pollution The unit will have 3 DG sets of 180 KVA, 380 KVA & 45 KVA, which will be kept as a stand- by and used in case of main power failure. The Diesel will be used as fuel for the DG Set and adequate stack height of 2.7 m, 3.9 m, 1.3 m will been provided. 4.3 Noise Pollution The only source of noise generation may be from the D.G. Sets, which will be kept as standby and no other source of noise and vibration from the proposed manufacturing activity except Plant machineries. The adequate precautions will be taken for abatement of noise pollutions All the measures would be taken to limit the noise levels at the plant boundary within 75dB(A) as per the stipulated limits. 4.4 Waste Management No solid waste is being generated from the assembly and PU Foam manufacturing process except scraps. Water requirement for the proposed PU Foam manufacturing unit is negligible as no water is used in the process. Hence, no waste water is likely to be generated during manufacturing process. However „waste foam‟ is generated during cutting process of quantity 3875 Kg/Month, which is being collected and reused again. TDI drums will be disposed off to the parties authorized in this regard. The details of solid waste generation and handling / Management are given in Table 4.2.
