Researchmethodology
SOLID WASTE MANAGEMENT
The Collection,transportationanddisposal of municipal solidwaste is
an obligatory functionof the Madurai Corporation.The Municipal
SolidWaste mainly comprises waste from households,market,
commercial establishments,hotels,hospitals andindustries in the
town. The public health department of the corporation,headed by
City Health Officer and Assistant HealthOfficer is responsible for the
SolidWaste Management in the city. For the efficient administration
and for day-to-day operational purposes,the town is divided into 4
Zones covering all the 100 Municipal Wards.

3. In Madurai City garbage is generatedat the rate of 406 gram per day
per head accumulating to a massivequantum of 548 Metric Tonper
day. This is slightly higher when comparing similar level of cities
where the per capital generationof waste is around 400 grams per
day and the reasonfor the excess rate of creationof waste is due to
the heavy influx of floating population which is estimatedto be
around 3 lakhs. Out the accumulatedgarbage releasedby the houses,
shops, daily and weekly markets,commercial establishments,hotels,
hospitals and industries,garbage generated from the house account of
64%. Householdwastes contains mainly residual vegetables and food
which couldbe easily disposed.But the scientific disposal of solid
waste such as plastic,paper dischargedby the commercial
establishments,without affecting the environment remains to be a
great challenge.
The various sources ofwaste generation in Madurai are detailed

Domestic Waste:
In Madurai the major source ofwaste generationhas been
households.The quantum of waste generatedfrom households is
around 288 tones per day, which is 64 percentage of the total waste
generationof the town. The householdwaste mainly consists of
organic waste such as Vegetable Waste,Food etc., whichcan be easily
disposed.
Commercial Waste:
Commercial establishments like Hotels, Restaurants,Shops,Trading
Units, Small time Street Traders,Marriage halls etc., generates solid
waste which mainly comprises ofpaper, plastics,foodleft-overs and
others in organics.Madurai has approximately 25 Daily Markets and 2
Weekly Markets.The total quantum of waste generated from these
sources is 108.00 tones per day, which constitutes about 24
percentage of the total waste generated. Waste Collectioninthe
Market areas and the bus stand are managed by means of contract
employees.
Industrial Waste:

5. As there is no major Industries inthe Corporationarea,the waste
from the existing units is not mixed with the municipal waste.
Hospital and Clinical Waste:
The Urban local body is maintaining a few health post and maternity
homes.In addition, the town being a district Headquarters has many
institutionof health. Hospital waste constitutes approximately 18.00
tones. Hazardous waste are collectedand disposedseparately
throughincineration and is not mixedwith municipal waste.
Waste from other sources:
The Municipal also collects waste generatedfrom streets sweeping,
drain desilting and construction.The quantity of solidwaste
generatedfrom the above sources is of the order of 36 tones per day,
which is about 8% ofthe total waste generation.
CompositionofWaste:
In 2004, a study of the waste characterizationofsolidwaste has been
conducted by Madurai CorporationApproximately 65.40% waste is
degradable, while the rest is Non-degradable (which mainly include
paper, plastic Gloss etc.,) the details are present below.
The primary collectionofwaste in Madurai Town is done by SHGin 7
wards and bus stands and throughprivatization2 wards and by
Corporation63wards.
2 Mission and vision overview
Madurai Corporation -Swachh Bharat Mission

6. Madurai Corporation has embarked on a journey to transform the city in to the cleanest city
in the country by 2017. In order to achieve this feat, it is important to eliminate open
defecation and promote healthy sanitation practices. According to 2011 census, Madurai has
around 20000 households without an attached toilet. To promote construction of toilets in
such house holds the Government of India and Government of Tamil Nadu are providing
grants for construction of IHHLs. However, this amount is not sufficient to construct a proper
sanitary toilet.
The Construction cost for a sanitary toilet varies from Rs 22000 to 26000 depending on the
sewerage treatment system. While the Government contribution is around Rs 8000, the rest
has to be borne by the beneficiary. Since most of these beneficiaries are very poor they are
not able to bear the balance contribution amount. Many beneficiaries are not willing to
construct toilets due to this reason and therefore the practice of open defecation still
continues.
The Swachh Bharat Mission encourages Private Sector participation in Capex (Capital
Expenditure) and Opex (Operation and Maintenance). Many PSUs and private companies are
funding toilet construction under their CSR activities. In Madurai for the current financial
year we have a target of 4382 IHHLs. To meet this ambitious target, we need financial support
from donors.

The Madurai Corporation is collecting solid waste by employing 2700 Sanitary Workers in
clearing the garbage using hand carts and Tricycles, who collections waste from Dustbins and
Dumper Bins.
Effects in privatization of collection have been made through employing of contract workers and
collection of waste from bus stand and other commercial areas. Privatization of Household waste
collection is under active consideration by the Corporation. Presently the corporation has also
engaged 70 contractual labourers for waste collection from markets and bus stand. The
Corporation has also appointed 12 SHG's with a total of appropriates 240 workers. The
Corporation has also engaged 200 Contract Workers for Garbage Loading on the transportation
vehicles.
The Corporation manages primary collection through 135 Tricycles (carrying capacity – 20
kg/Tricycle) and 150 Hand Carts (carrying capacity – 100 kg/hand cart). Collection and transfer of
waste to collection points is also managed by Auto minder (57 rented vehicles are being used).
There are 74 Dumper Bins with a total carrying capacity of approximately 100 tones placed at
main collection locations around the city. Night sweeping is done effectively around the temple
areas, the core city areas, some markets and around bus stands.
In Madurai Corporation waste transportation is being carried out using open vehicles. Transfer of
garbage to collection points is done by corporation owned hand carts, Tricycles and rented
Vehicles like Auto minders, which is further taken to dumping yard by means of corporation own
vehicles (Lorries and Dumper Placers) and rented vehicles (Tractors).
Transportation of waste is managed by 12 Corporation own vehicles and 65 hired vehicles. The
Corporation is collecting and transporting 410 MT of waste to the Dump site based on varying
number of trips assigned and undertaken by these vehicles. The details of waste transportation
vehicles are detailed below:

5 Recommendations:
The municipalities have to work more effectively by increasing the capacity of waste
treated &collected
on daily basis by strengthening the partnerships with PPP projects
The Private waste management companies should be given tax evasions and
relaxations on loans on investments made for business operations to increase the
entrepreneurial initiatives.
Working with the informal sector would increase the efficiency and coverage of the
waste management process across the initiatives.

21. Reducing the amount of garbage tipped in the landfills should be regulated by
checking that the waste has been strictly passedthrough segregation and treatment
process to reduce the carbon foot print and pollution of the environment.
As the society is susceptible to throw the garbage anywhere unthinkably many public
dustbins should be placed at 10 mtrs distance, educating the citizens about the civic
sense and hygiene is important. Most importantly public areas like vegetable and meat
markets.
