Solid waste information of Faisalabad
INTRODUCTION
In natural systems there is no such thing as waste. Everything flows in a natural cycle of use and
reuse. Living organisms consume materials and eventually return them to the environment,
usually in a different form, for reuse. It refers to any variety of discarded materials, not liquid or
gas that is deemed useless or worthless. Unfortunately, what is worthless to one person may be
of value to someone else. Solid wastes are really misplaced resources. Therefore, learning how to
effectively reduce the amount wastes and to recycle valuable resources from them is important if
humans wish to maintain a livable and sustainable environment.
Ancient cultures dealt with waste disposal in different ways: dump it outside their settlements;
incorporate some of it into flooring and building materials; recycle some of it. Dumping and/or
burning solid waste has been a standard practice over the centuries.
SOURCES AND TYPES OF SOLID WASTE
There are two basic sources of solid wastes:
Non municipal
Municipal
Non municipal solid waste
Non municipal solid waste is the discarded solid material from industry, agriculture, mining, and
oil and gas production.
Some common items that are classified as non municipal waste are: construction materials
(roofing shingles, electrical fixtures, bricks); waste -water sludge; incinerator residues; ash;
scrubber sludge; oil/gas/mining waste; railroad ties; and pesticide containers.
Municipal solid waste
Municipal solid waste refers to the discarded solid materials from residences, businesses, and
city buildings.
Municipal solid waste consists of materials from plastics to food scraps. Generally, the most
common waste product is paper (about 40% of the total). Other common components are yard
waste (green waste), plastics, metals, wood, glass and food waste. The composition of the
1
municipal wastes can vary from region to region and from season to season. Food waste, which
includes animal and vegetable wastes resulting from the preparation and consumption of food, is
commonly known as garbage.
Hazardous waste
Some solid wastes are unsafe to the health and well-being of humans. These materials are
classified as hazardous wastes. Hazardous wastes are defined as materials which are toxic,
carcinogenic (cause cancer), mutagenic (cause DNA mutations), teratogenic (cause birth
defects), highly flammable, corrosive or explosive. Although hazardous wastes in the United
States are supposedly regulated, some obviously hazardous solid wastes are excluded from strict
regulation: mining wastes and hazardous household and small business wastes.
Background information of Faisalabad
Faisalabad, formerly known as Lyallpur, is the largest metropolis in Pakistan, the second largest
in the province of Punjab and a major industrial center in the heart of Pakistan.
The city is at a road and railway junction, which has played an influential role in the
development of Faisalabad’s trade and economy. It is known for production of cotton, wheat,
sugarcane, vegetables, and fruits, which form 55% of Pakistan's exports. The city is an
industrial centre with major railway repair yards, engineering works, and mills that process
sugar, flour, and oil seed. Produce includes super phosphates, cotton and silk textiles,
hosiery, dyes, industrial chemicals, beverages, apparels, pulp and paper, printing,
agricultural equipment, and ghee. Faisalabad is famous for its Export Quality Textile Products.
Sources of city’s solid waste
City’s waste mostly composed of;
Domestic and municipal waste (largely consist of rags, polythene bags and plastics) including
garbage and trash

Solid Waste Management of Faisalabad
Solid Waste Management plan of Faisalabad consists of following steps.
Establishment of a Solid Waste Management Department (SWM) in the Faisalabad City
Replacement of old method of sweeping by sanitary workers on main roads with
mechanical road sweepers.
Placement of containers at the temporary Transfer station where previously the waste was
lying openly.
Development of proper landfill site in process.
Shifting of cattle from the main city.
Approximately 1359-1500 tons of waste produces daily.
Only 70% is transferred to the dumping site with existing machinery.
Inadequate number of vehicles for transportation of waste.
3
Non-availability of facility of segregation and recycling of inorganic waste.
No proper workshops for vehicles maintenance and repair.
CURRENT STATUS OF SOLID WASTE MANAGEMENT
In Faisalabad the Solid Waste is being disposed off without any precautionary measures.
No treatment of wastes is carried out except for incidental recycling by scavengers.
No system exists for the separate disposal of hazardous waste.
No measures are being taken to negate adverse environmental effects.
There is as yet no monitoring of air quality in the city.
No facility exists for the treatment of affluent from the industrial plants.
Textile and grain mills are a major source of air, land and water pollution.
Dying process in a textile industries are major source of pollution.
Noise and offensive industrial odors are serious problems
Untreated industrial water is the serious source of pollution.
SWM in urban policy making
The population of the Faisalabad City is more than 2.3 Million and daily production of Solid
Waste is about 1350-1500 Tons but the lifting capacity of the Solid Waste by the fleet of
vehicles and allied machinery available to the City District Government is about 900 tons.
Remaining waste remains unfitted in open areas of different localities especially unconstructed
residential or commercial plots of different areas. No facility for the treatment of wastes is
available. No system exists for the separate disposal of hazardous Solid Waste.
Total waste production and recycled waste
In (EPMC Estimates 1996) total waste estimated and recycled is as follows;
Parameter Per capita Kgm / p/d Total Tons / day
Municipal Waste
production
0.324 598
Recycled waste 0.092 170
Total waste delivered 0.388 716

to transfer points
These figures are based on an estimated population of about 1,850,000. The figure for total waste includes
figures of about 118 tons per day for street sweepings and 93 tons per day for animal waste. A recent City
District Government estimate puts the total per-capita waste production at 0.5kgm per day and the total
waste arising figure for Faisalabad City at 1350 tons per day.
Waste composition reveals the following major components: (EPMC Estimates
1996)
Food (10-23.5%)
Recyclables (13.6-.23.55%
Grass/leaves straw (10-21%)
Fines fraction (34.2-56.7%)
Plastics, paper, textiles and stones (3-6%)
According to district government, an estimate of daily generated and lifted waste is as follows:
Daily waste generation is calculated on the basis of per capita waste generation assumed at 0.5
Kg/cap/day for Faisalabad city.

Paper & plastic waste generation
As a proportion of total municipal waste stream, the
share of Plastic is more or less equal to the figure of
some developed countries. However, it is important to
note that the ratio of Plastic in municipal solid waste
decrease to less than 1% as the informal Collectors pick
up plastic, paper and metallic waste to sell them for their economic returns.

Hospital waste:
According to Journal of Advanced Research (2013) average waste generation in various hospitals
is 1.12 kg per day per bed. The studied hospitals generate approximately 5.5 tons waste day-1.
Waste is broadly classified as follows:
Infectious waste 12%
Non infectious (general) waste 78%
Recyclable waste 66%
Paper 5%, plastic 55%, textile 10%, glass 30% (Journal of Advanced Research 2013)
Types of infectious hospital waste produced by hospitals in faisalabad is listed below:
Clinical waste 63%
Pathological waste 65%
Radioactive waste 48%

This study shows that G1 hospital is one of the big hospitals (1300 beds) in district Faisalabad
and generates large quantity of waste (1750 kg-1 day-1). Number of beds in G2 hospital is about
1 times less than G1 hospital and waste generated by the G2 hospital (740 kg-1 day-1) is greater
than G1 hospital.. In general, public hospitals generate large amount of waste, trust hospitals
generate medium and waste generation rate of private hospitals is much less than those of public
and trust hospitals.
Final disposal of hospital waste includes:
By dumping 20%
By incinerator 20%
By municipal corporation 60%
Only two hospitals Allied and District headquarter have facility of incinerator. Waste is unsafely
disposed of in over loaded transportation.(Journal of Advanced Research 2013)
Industrial sector:
A total of 794 209 kg day-1 (289 886 285 kg year-1) solid waste is produced by this sector. No
waste is sent to landfill. The waste is first segregated into different categories/ types by hand and
then weighed. Cotton waste is sold to brick kilns where it is used as an alternative fuel as it is
cheaper than wood/coal.
Agriculture sector:
The city has developed a comprehensive electricity generation plan to make crop waste usable
which is consists of collection of waste, processing, transportation and power generation. This
considerably reduces waste produced by this sector.
Impacts of solid waste
Some of the impacts of solid waste which have been reported till now in Faisalabad are described
below.
Industrial waste

As might be expected, the textile and grain mills are a major source of air, water and land
pollution. Local studies (Ahmad et al, 1989 and Ahmad 1990) have shown that chemicals used
by the textile industry impact the heart and liver significantly. Dying processes in the textile
industry are also major sources of pollution that go unchecked. Noise and offensive industrial
odors are generally recognized as serious problems, but they are neither monitored nor
controlled. Untreated industrial water is the main source of pollution and is dangerous to both
human and marine life. Particularly dangerous are the liquid effluents created by textile factories.
These become more hazardous when they are channeled into the domestic sewer system. The
negative impact on the overall quality of the environment, especially on ground water quality,
becomes still more serious. This is because many of these discharges contain significant
quantities of heavy metal and contaminants from chemicals used in the dye or bleaching
processes associated with textile industries and soap making units. Furthermore, the unrestricted
use of these effluents in the production of crops, especially vegetables, has adverse effects on
human and livestock health. Similarly, emissions of smoke, other gases and fumes from the
industrial establishments create serious health hazards.
Hospital waste & Municipal waste
The three major diseases are reported by the health department; however, these have changed
slightly over the past 27 years. In 1970, these were TB, malaria and typhoid. By 1997 malaria
had been brought under control, and the three main diseases were typhoid, dysentery and liver
disease. It does not have data on the incidence of other diseases, but these few observations
indicate that infectious diseases are still paramount. Moreover, they derive from environmental
conditions that could be controlled by a more adequate urban infrastructure, in particular the
provision of clean water and the more effective management of human waste.
Management
Landfill site consisting of 40 acres of land is available but the filth is being dumped there in the
open. Initially a trench was dug where the Solid Waste was dumped in layers, each layer covered
with the earth. This trench had no lining to prevent the seepage of leachet to the ground water.
After the filling of this trench no other trench was dug. No machinery is available such as
bulldozer and excavator to dig the trench and to compact the Solid Waste.
