CHAPTER NO.6
CASE STUDIES
6.1 SUNDAR INDUSTRIAL ESTATE (SIE)
Spread over an area of 1602 Acres, SIE is located approximately 45 km from the
centre of Lahore on Sunder Raiwind Road. It is one of the largest and the most modern
industrial estate in Punjab. The main features of the project are strategic clustering of
specific industries for allowing shared usage of common services, the provision of
utilities (Power, Water, and Gas) and a well built road network. The project was
envisioned to encompass effluent treatment services, technical training centre, and
commercial centre and one-window operation aimed to create a customer friendly
environment. As noted above, industrial estates can be classified by a number of factors,
such as location, industrial activity, motivation, and ownership. The location of the estate
might be “urban”, “semi urban” or “rural”. An estate also varies according to the
functions it performs and the nature of firms operating in the estate. A “composite estate”
is composed of industries belonging to various sectors, an “ancillary estate” contains
numerous small enterprises linked to an overarching sector while a “single trade estate”
contains firms relating to a similar industrial sector. The objectives of an estate can be
“developmental”, “promotional” or “dispersal”. The sponsorship of an estate can be
“governmental”, “private” or “private-assisted”. Sundar Industrial Estate, analyzed within
this framework of classifications, can be categorized as a composite semi-urban estate,
hosting industries from over eight different sectors and located close to rural and urban
areas. Its objectives are developmental and its ownership is private-assisted.

6.2CONCEPTION & DESIGN
The estate was conceived in 2004 and became operational in 2007. In the initial
phase, Pharmaceuticals, Food Processing & Storage, Engineering and Textile were
encouraged. Other industries allowed came under the “miscellaneous “industry category.
A total of 691 plots were created. Most of these plots were meant for small to medium
sized industries. The average lot size was half an acre to two acres with bigger plots of up
to 11 acres to accommodate large industries. Out of 1,603 acres about 1,028.56 acres
were industrial plots while the remaining area was dedicated to roads, infrastructure,
amenities, utilities, commercial area, green belt, etc.
The degree of speculation spurred determines the degree of industrialization and success
of an estate. The preferential policies of the government (including inexpensive land, tax
breaks and export tax exemption etc) provide the necessary stimulus for investment in a
project. While in SIE’s case, the estate did spur a great deal of speculation even though
the fiscal incentives provided by the government were quite low. These included: land at
a discounted rate (plot price was discounted from Rs. 5 million to 3.5 million per acre,
meaning a subsidy of 1.5 million per acre), the Capital Value Tax (CVT) on transfer of
property was reduced from Rs. 100 per sq.yard fixed by the federal government to 2%
and additionally soft loans of Rs 1.5 billion for initial investment in the project were
made available. Apart from these no other fiscal incentives were provided as the federal
government in Pakistan does not have a policy for specific incentives for industrial
estates. The speculative element of SIE can be judged from the fact that although all plots
Were sold in 2004, still by 2010 a majority of plots were not industrialized. Thus the new
provincial government recently launched a colonization drive to restrain speculation and
to try to weed out non serious investors.

4. 98
6.3 PLOT DISTRIBUTION
Small & medium entrepreneurs were focused, hence majority of plots are of sizes
between ½ acre to 2 acre. However, there are some bigger plots to accommodate large
industrialists as well.
Plots were created of the following sizes:
 ½ Acre 112 Plots
 1 Acre 396 Plots
 2 Acres 101 Plots
 3 Acres 37 Plots
 4 Acres 14 Plots
 5 Acres 34 Plots
 Above 5 Acres 22 Plots
 TOTAL : 702 Plots
6.4 LOCATION & TRANSPORTATION:
The selected location of Sundar Industrial Estate offers tremendous potential for
growth and success. It is located in a lagging area adjacent to Bhai Kot village, only 9km
away from the town of Raiwind which hosts a large number of industrial set ups, and 25
km South of Lahore. Although SIE is not located in an urban area, a well connected road
network provides easy access to urban markets.

6.4.1 CRITICAL REVIEW ON LOCATION OF SIE
Pakistan has a population of about 180 million fed through its prime agricultural
lands of the provinces of Sindh and particularly Punjab. According to international
standards, locating industrial estates in agricultural areas (primate agriculture land in this
case) is a widely criticized policy because it can have tremendous social, economic and
ecological consequences. Nadeem argues that SIE was imposed on prime agricultural
land while ecological considerations and the possible negative effects of creating an
industrial estate in this area have not been given sufficient weight age. He challenges the
SIE’s Environmental Impact Assessment’s declaration that most impacts of SIE are low-
adverse to medium-adverse, disagreeing that the land used for the project was barren,
while making a case that SIE has had significantly negative environmental impacts and
only minimal efforts were made to comply with environmental regulation as well as to
compensate the affected individuals. His main claim that the land was used for
agriculture prior to SIE project development is supported by this author’s own
observations and visits to the estate as even today large surrounding areas are under
cultivation (some vacant plots within SIE give a sight of agricultural land). But now that
SIE has-been established it is particularly important to ensure that industrial waste and
associated effluents are properly treated to not adversely affect the agricultural
surroundings of SIE. In analyzing the location of SIE based on the access to labor market,
degree of industrialization of the host community, access to major cities, distance from
large industrial complexes and transportation infrastructure, the SIE gets a mixed
assessment. While the distance from large industrial site of Raiwind and road
infrastructure are good, the cost of transporting labor, raw materials and finished goods is
higher given the distance from Lahore. Additionally the lack of transport facility within
and to the estate hinders both labor and investor accessibility1

6.5 INFRASTRUCTURE FACILITIES:
Location factor is further augmented by a comprehensive set of infrastructure
facilities offered at SIE unparallel to any other industrial estate in Pakistan. A comparison
of SIE’s infrastructure to industrial estate’s across the country makes it evident that SIE
has set a new precedent for industrial standards in Pakistan. The other industrial estates
have failed to provide the very basic facilities to its occupants and had been an
illustration of mismanagement and uncongenial environment prior to 2004.Some other
industrial estates which failed to provide basic facilities like QIE had operated without a
road network, sewerage system, water drainage system and solid waste disposal system
up until recently. A simple comparison is the internationally compatible underground
electricity distribution system at SIE not available in any other industrial estate in the
Punjab.
It is evident from the literature review that well functioning infrastructure is a major
determinant of vocational decisions and is imperative for the success of an industrial
estate. Infrastructure that facilitates the induction and generation of investment is pivotal
for an IE. The central motivation of establishing SIE was to compensate for the lack of an
estate equipped with appropriate infrastructure in the province of Punjab. According to
ex-CEO, “SIE was established with a clear vision of providing quality infrastructure
which was absent in all industrial estates in Punjab.” Outstanding infrastructures are thus
one of the primary distinguishing features of SIE and play an instrumental role in its
performance. An important function of the estate is to provide common facilities to the
investors. These can be categorized into common production or service facilities. The
common production facilities include separate units or equipment to provide special
services for use by estate tenants.26 Some of the proposed common production facilities
at SIE include a Common Effluent Treatment Plant (CETP), a technical training centre
and a pharmaceutical laboratory but construction has not yet begun for any of them.

9. 103
6.5.2 ROAD NETWORK
A well-working and reliable road network is essential for smooth operations in the
estate to ensure easy mobility of goods and raw materials in and out of the estate. The
road size at SIE allows easy and swift mobility and is adequate for the estate’s current
needs. The main road has six lanes, is 200 feet wide while the inner roads are 120 and 80
feet wide respectively. This allows for smooth flow of traffic even in times of vehicle
loading, unloading and parking2
6.5.3 DRAINAGE SYSTEM
The current drainage system at the estate has not received a satisfactory
evaluation from the experts. Its soaking wells located in the green belts are not providing
adequate drainage and it is recommended that a conventional storm water drainage
system should be designed for the SIE. Generally governments provide incentives to the
industrial sector to encourage and promote a drainage system. These can either be
provided to all entrepreneurs, or to industrialists operating in specific geographical areas
of the estate.
6.5.4 WATER SUPPLY SYSTEM
The water supply system comprises of three tube wells with a capacity of 4 cusecs
each and ten elevated RCC water tanks of 100,000 gallon capacity each, providing a total
storage capacity of one million gallons of water for the entire estate. So for an area of
1,602 acres 1,000,000 gallons of water is available, meaning 624.2 gallons per acre
against the international standard of 4, 284 gallons per acre. This system can only serve
the estate for 45 minutes at peak demand. In line with international standards the storage
capacity of overhead water tanks needs to be increased.3

6.5.5 HIGH PRESSURE NATURAL GAS SUPPLY
The authorities have constructed high pressure natural gas pipe line network
throughout the estate to facilitate gas supply to the consumers. However, the gas supply is
controlled by SNGPL (state run utility). Due to the shortage of natural gas throughout
Pakistan, gas consumers in SIE also have to endure hours of gas load shedding. It is one
of the most crucial and pressing issues faced by the industrialists. The unavailability of
gas is forcing many businesses to shut down permanently and some temporarily. Most are
in a fix due to approximately 12-15 days per month of load shedding in the winters.
6.5.6 WASTE WATER COLLECTION SYSTEM
The disposal of wastewater is being carried out through septic tanks at different
locations in the estate. The NESPAK report states that septic tanks (settling tanks) should
be complemented by a Proper screening mechanism that minimizes entrance of solids
into the tanks. According to this review, the RCC pipes used in the wastewater disposal
system are undersized and the velocity in various pipe segments lower than needed
leading to deposition of solid particles which could potentially choke the system.
Minimum cover over RCC pipes should be 1 m (3.28 ft), however at SIE it is 2.5 feet
generally and 1 foot at certain locations. Out of the 25 investors interviewed, only 15
were satisfied with the wastewater system, considered it average and 8 rated it as poor.
This could also be due to various reported cases of excessive water present on the road in
front of factories with higher water usage like paper factories and dying mills. For
effective utilization of the current system, it is strongly recommended that thorough
cleaning of septic tanks is carried out on a routine basis.
6.5.7 SOLID WASTE MANAGEMENT SYSTEM
For an estate as large as SIE and claiming international standards, it is
unreasonable that solid waste collection and disposal services are provided. The landfill
site located within the estate.

11. 105
6.5.8 TRANSPORT
40% (10 out of 25) of the investors have to transport all their labor from Lahore to
SIE and another 44% (11/25) have more than 50% labor coming from Lahore. Keeping
these figures in view, a common transport (shuttle/bus service) service from Lahore to
SIE needs to be provided. Additionally, travel within the estate is highly inconvenient
and time consuming as walking from the main gate to factories located far can take up to
half an hour. More importantly, transporting all skilled labor from Lahore is not a
sustainable solution to a lack of skilled labor in the area and is particularly difficult in the
absence of a transport system from Lahore to SIE and residential area for labor within
SIE.
6.5.9 CANTEEN
A Canteen with affordable food is essential for the estate. In the absence of a
transport system within the estate, for a worker to go outside the estate for food, simply
walking towards the closest urban area may take up most of the lunch break. Thus many
factories provide food within their premises, but this may not be suitable for all industrial
units. Thus it is recommended that SIE needs to provide at least three Canteens in the
estate area.
6.5.10 MEDICAL SERVICES
One of the most critical service lacking is the medical service.100% of the
investors rated the medical services as poor. At least five indicated that no medical staff
was present when they visited the facility in time of need. They stated that the hospital
did not have adequate staff or equipment to deal with emergency cases and thus laborers
had to go to the nearest Social Security Hospital in case of emergency. The lack of local
and external transport service makes workers even more vulnerable in case of an
accident.
6.6 INDUSTRIAL ZONES AT SIE:
 Pharmaceuticals
 Food Processing
 Engineering
 Textile/Garments
 Carpet

12. 106
 Paper & Board
 Plastics
 Electronics
 Chemicals
 Paints
 Steel
 Auto parts
 Wood products
 Warehouse etc
Infrastructure and facilities provision at SIE has set a precedent for industrial estates in
the Punjab in terms of better planning and implementation. However, there is
considerable room for improvement.
6.7 THE SYMBIOSIS INSTITUTE AT KALUNDBORG IN DENMARK
The example of Kalundborg in Denmark strictly speaking is an example of an
industrial Network, and not an industrial estate. However, as a case study it is an
excellent illustration of the application of an Industrial Ecology approach and is certainly
relevant to an industrial estate. The example of Kalundborg is often quoted in the
literature, perhaps because it is simple enough to allow the idea of an industrial
ecosystem to be appreciated and yet sufficiently sophisticated to give a feeling for the
enormous potential of this approach.
6.8 THE HISTORY OF KALUNDBORG EIPS
The history of Kalundborg really began in 1961 with a project to use surface
water from Lake Tissø for a new oil refinery in order to save the limited supplies of
ground water (Christensen, 1999). The city of Kalundborg took the responsibility for
building the pipeline while the refinery financed it. Starting from this initial
collaboration, a number of other collaborative projects were subsequently introduced and
the number of partners gradually increased. By the end of the 1980's, the partners realized
that they had effectively "self-organized" into what is probably the best-known example
of a working industrial ecosystem, or to use their term - an industrial symbiosis.

14. 108
6.9 INDUSTRIAL SYMBIOSIS
Symbiosis means co-existence between diverse organisms in which each may
benefit from the other. In this context, the term is applied about the industrial co-
operation taking place in Kalundborg between a number of companies and Kalundborg
Municipality, all of which exploit each other’s residual or by-products mutually.The
Symbiosis co-operation has developed spontaneously over a number of decades and
today comprises some 20 projects. The exchange of residual products between the
companies is laid out in the diagram. The Industrial Symbiosis of Kalundborg is built as a
network co-operation between six
Processing companies, one waste handling company and the Municipality of Kalundborg.
The philosophy behind the Symbiosis is that the six companies:Energy E2 Asnæs Power
Station, the plasterboard factory BPB Gyproc A/S, the pharmaceutical plant Novo
NordiskA/S, the enzyme producer Novozymes A/S, the oil refinery Statoil A/S,
Bioteknisk JordrensSoilrem A/S as well as the waste company Noveren I/S and
Kalundborg Municipality exploit each other's residual or by-products on a commercial
basis.
One company's by-product becomes an important resource to one or several of the other
Companies. The outcome is reduced consumption of resources and a significant reduction
in environmental strain. The collaborating partners also benefit financially from the
cooperation because the individual agreement within the Symbiosis is based on
commercial principles.

6.10 Exchange of Resources
6.10.1 STEAM AND HEAT
Asnæs Power Station produces heat for the city of Kalundborg and process steam
for the Statoil Refinery, Novo Nordisk A/S and for Novozymes A/S. The combination of
heat and power production results in a 30% improvement of fuel utilization compared to
a separateproduction of heat and power.
Approximately 4,500 households in Kalundborg receive district heat from Asnæs Power
Station. District heat has replaced approx. 3,500 small oil-fired units.Statoil Refinery
receives process steam and water from Asnæs Power Station. The steam Covers about
15% of the refinery’s total consumption of steam. The refinery uses the steam for heating
oil tanks, pipelines etc. Novozymes A/S and Novo Nordisk A/S use steam from Asnæs
Power Station for the heating and sterilization of the processing plants. Some of the
cooling water from Asnæs Power Station is used by a fish farm producing 200Tones of
trout and salmon on a yearly basis. The fish have better growth conditions in the heated
water.
6.10.2 WATER
The Kalundborg Region as well as the industrial companies is large consumers of
water. This is why the Symbiosis companies are seeking to recycle as much water as
possible. Asnæs Power Station has, for example, reduced its total water consumption by
60%. Previously Asnæs Power Station used ground water for its power and heat
production only. The ground water has now been substituted by surface water from the
lake of Tissø and treated wastewater from Statoil. These efforts have enabled Asnæs
Power Station to reduce its ground water consumption by 90%. Earlier, Novozymes A/S
also used ground water exclusively for processes requiring drinking water quality. 1
million cubic metres of ground water have now been substituted by lake water from Tissø
whose water has been processed up to drinking water quality by Kalundborg
Municipality.
As the water from Tissø is not an unlimited resource, the consumption of lake water has
gone down by 50%. Asnæs Power Station has accomplished this reduction by recycling
its own wastewater.

17. 111
6.10.3 WASTEWATER
The wastewater is led to a recycling reservoir together with the runoff from the
surrounding fields and surplus water from Tissø in the winter period. The recycling
reservoir has acapacity of 220,000 cubic metres of water, which are used in the power
station processes.
The wastewater from Novozymes A/S and Novo Nordisk A/S is part of a genuinely
symbiotic relationship: Novozymes A/S treats all wastewater up to a level corresponding
to the wastewater of an ordinary household. From Novozymes A/S, the treated
wastewater is pumped to the treatment plant of Kalundborg Municipality where a final
treatment process takes place.
The Novozymes A/S wastewater is of a relatively high temperature making it easier for
themunicipal treatment plant to treat its wastewater. In this collaboration process, the
environment is also the winner as the overall discharge of nitrogen into Jammerland Bugt
isvery limited. Wastewater is also discharged from Asnæs Power Station into the
treatment plant of Kalundborg Municipality.
6.10.4 REFINERY GAS
An “eternal” flare of surplus gas is part of the safety system in any refinery.
Statoil's refinery flare has been reduced to a mere night-light, because the refinery now
exploits its own surplus gas internally. Formerly a large portion of the gas was
transported by pipeline to BPB Gyproc and Asnæs Power Station to be used in their
production.
6.10.5 GYPSUM
The desulphurization plant of Asnæs Power Station, which removes sulphur
dioxide (SO2) from the flue gas, produces about 200,000 tones of gypsum on a yearly
basis. Desulphurization is a chemical process in which sulphur dioxide (SO2) is removed
while forming the by-product gypsum. The gypsum is sold to BPB Gyproc A/S, a
company that manufactures plasterboard products for the construction industry. The
gypsum from the power station reduces the import of natural gypsum significantly. Being
more uniform and purer than natural gypsum, power station gypsum is therefore well

18. 112
suited for the plasterboard production. Gypsum stemming from the municipal recycling
station of Kalundborg is delivered to BPB Gyproc A/S, thereby contributing - on a
smaller scale - to reducing imports of natural gypsum and the amounts of solid waste for
land filling.
6.10.6 SLUDGE
Sludge is a major residual product stemming from the municipal water treatment
plant in Kalundborg. The sludge is utilized at A/S Bioteknisk Jordrens Soilrem as a
nutrient in the bioremediation process. In this way, a waste product from one process is
applied as a useful resource in another process.
6.10.7 OTHER WASTE
Noveren I/S collect waste from all Symbiosis companies. Waste that is an integral
part of various processes. In return, the participating companies receive raw materials.
Noveren I/S produce electricity on the basis of landfill gas. This electricity is resold to
power companies. In addition, Noveren I/S delivers a total of approx. 56,000 tones of
combustible waste on a yearly basis corresponding to an energy consumption of approx.
6,500 private households in terms of power and district heating.
6.11 PROFITS
Such an approach can lead to a significant reduction in the environmental impact, as is
shownin Table7.2 (Erkman, 1998):On the other hand, this symbiosis also reduced the
cost. Each exchange is based on a separate contract between the two partners involved,
revenues can be estimated as coming from selling the waste material and from reduced
costs for resources. The partners estimate that they have “saved" $160 million so far
(Christensen, 1999). The payback time of a project is less than 5 years on average.
Therefore, a more rational utilization of resources can save money.

6.12 CONCLUSION
According to the analysis above, we can find a number of advantages from the symbiosis
that is used in the EIP of Kalundborg.
 Recycling by-products. The by-products from one company become the resource of
Another company;
 Reduced the consumption of resources, e.g. water, coal, oil, gypsum, fertilizer etc.;
 Reduced the environmental strain. Reduced CO2 and SO2 emission, reduced
discharges
Of wastewater and less pollution of wastewater etc.;
 Improved utilization of the energy resources. Waste gases are used in the energy
Production;
 Reduced the investment cost and shorten the payback time.
On the other hand, the symbiosis still has one disadvantage that in such a carefully
planned and integrated industrial system the individual parts would be too closely linked
and dependent on each other, rendering it fragile and hence likely to collapse.
