PRE FEASIBILITY REPORT
1.0. EXECUTIVE SUMMARY
Tamilnadu has seen a steady growth of industries in the recent years. The Government of
Tamilnadu, while positively encouraging the industrial growth, is also conscious about the
environmental considerations of the industries. In view of the same, it had taken steps to
establish Common facilities for treatment and disposal of Hazardous Waste.
During the Budget Session 2014 -2015, the Honorable minister of Industries, has made an
announcement while moving the Demand for Industries Department, on 14-07-2014, that
States Industrial Promotional Corporation of Tamilnadu (SIPCOT), will set up Hazardous
waste treatment and storage facility in an area of 20 acres in Thoothukudi Industrial
complex and Perundurai Industrial Growth Centre vide G.O (D) No: 96, dt 18.07.2014
enclosed in Annexure 1. At present only one site at Gummidipoondi, near Chennai is
available to cater to the needs of entire Tamilnadu. In order to reduce the transportation
cost and also SIPCOT wants to provide it as an infrastructure to facilitate the growth, it
was decided to have two more disposal sites.
As per the instruction of Supreme Court monitoring committee, TNPCB has formed a core
committee to identify a site and service provider to facilitate the Hazardous Waste disposal
in Tamil Nadu, in the year 1996. The core committee has later formed as a special purpose
vehicle designated as Industrial Waste Management Association (IWMA) in 2002. The
organization has already operating a scientific landfill facility in SIPCOT Industrial
Complex, Gummidipoondi, Chennai and is complying with all the statutory requirements
as stipulated by the regulatory authorities in respect of the Air Act, Water Act and
Hazardous Waste (Management & Handling) Rules 1989. Since the hazardous waste
generated by industries in Tamil Nadu cannot be accommodated at Gummidipoondi alone,
another TSDF has been proposed at SIPCOT, Thoothukudi, which will help in the
disposal of hazardous waste within various industrial premises in and around
Thoothukudi. The facility is located strategically at SIPCOT, Thoothukudi, which is a
major industrialized zone and SIPCOT has provided land for the development of Common
Hazardous Waste Management Facility (CHWMF) as referred in Annexure 1. SIPCOT
has identified IWMA as the nodal agency to establish CHWTSDF at Thoothukudi and to
Pre Feasibility Report for the Proposed CHWTSDF at SIPCOT, Thoothukudi by IWMA
4RamkyEnviroEngineersLimited
provide services and operate to that of CHWTSDF, Gummidipoondi. To this effect
SIPCOT has authorized IWMA to obtain necessary environmental clearances as required.
The proposed facility will cater to environmentally and economically sound disposal of
waste generated in this region, minimizing long distance haulage of waste.
As per EIA Notification S.O.No 1533 dated 14th Sep 2006 and its subsequent
amendments the proposed project is falling under Project / Activity 7 (d) Common
Hazardous Waste Treatment, Storage and Disposal Facility (TSDFs), Category “B” (All
facilities having landfill only) and requires environmental clearance from State Level
Expert Appraisal Committee, Tamil Nadu.

2.1. Identification of the project and Project Proponent
In view of increasing industrial activity in the state leading to an increasing industrial
waste load, industries and TNPCB encouraged formation of a special purpose vehicle
designated as IWMA.
IWMA is an umbrella organization of industries generating hazardous waste formed in the
State of Tamil Nadu primarily addresses the issues of hazardous waste disposal. IWMA
has in recent years, facilitated a hazardous waste disposal site in Tamil Nadu for the safe
and secure handling of waste without affecting the environment.
2.2. Scope of the project
Establishment of the facility on Build Own and Operate (BOO) basis by a
competent service provider.
Collection and Transportation of hazardous wastes from the generators facility
to the CHWTSDF duly following the manifest and other regulatory
requirements.
Carrying out comprehensive and finger print analysis of wastes as per
hazardous waste (Management, Handling and Transboundary) Rules, 2008
Disposal of waste in a secured landfill with or without pre-treatment based on
the finger print analysis and waste acceptance criteria.
Collection of user charges from the generator
On-site Environmental Monitoring including emergency procedures
Periodical Reporting to regulatory authorities
Following proper procedures for construction, operation and closure of the
facility.
Undertaking closure and post-closure measures and monitoring on exhaustion
of the site capacity or at the end of project whichever is earlier

2.3. Need for the Project and its Importance to the Country and or Region
There is a growing concern all over the country for the disposal of hazardous wastes
generated from anthropogenic sources. The waste generators find it difficult to dispose
their hazardous wastes without causing environmental disturbance; very few appropriate
disposal facilities are available. The Government of India has promulgated the Hazardous
Waste (Management & Handling) Rules in 1989 through the Ministry of Environment and
Forests (MOEF) under the aegis of Environment (Protection) Act [E(P) Act], 1986. Also
in order to encourage the effective implementation of these rules, the MOEF has further
amended the rules several times.
The hazardous wastes need to be disposed off in a secured manner without causing
significant environmental damage in view of their characteristics such as toxicity,
corrosively, ignitability, reactivity and persistence. The Schedule I and II of Hazardous
Waste (Management & Handling) Rules 1989 and subsequent amendments clearly
identify hazardous waste from processes and concentration based hazardous waste.
Secured landfills may be designed to accept the following hazardous waste;
Wastes which do not exceed biodegradable organics more than 5 % and total
Organic content more than 20% and wastes which do not have calorific values
more than 2500 Kcal/kg.
Sludge from effluent treatment plants
Air pollution control dust and sludge
Incineration residues
Organic chemical residues amenable to stabilization
Oil refinery waste and sludge amenable to stabilization
Pesticide bearing waste amenable to stabilization
Waste from paints and coating industries amenable to stabilization
Waste from pharmaceutical industries amenable to stabilization.
The primary objective of this project is to provide a common landfill facility to cater to the
industrial solid/ hazardous wastes.

3.0. PROJECT DESCRIPTION WITH PROCESS DETAILS
3.1. Type of the Project
The proposed project is a Common Hazardous Waste Treatment, Storage, Disposal
Facility (CHWTSDF) located at Mellavittan Village, SIPCOT Industrial Complex
Phase – I, Thoothukudi District, Tamil Nadu, and its neighboring districts for the safe
disposal of hazardous waste.
3.2. Need for the Project
Industrial operations lead to considerable generation of hazardous waste. The major
hazardous waste-generating industries in Tamil Nadu include textile, tannery,
petrochemicals, pharmaceuticals, pesticides, paint and dye, petroleum, fertilizers, asbestos,
caustic soda, inorganic chemicals and general engineering industries. Hazardous wastes
from the industrial sectors mentioned above contain heavy metals, cyanides, pesticides,
complex aromatic compounds (such as PCBs), and other chemicals which are toxic,
flammable, reactive, corrosive or have explosive properties affecting the environment.
Though the CHWTSDF exists at Gummidipoondi, near Chennai and authorized to collect
waste from the entire state of Tamil Nadu, the transportation cost for the disposal of waste
generated from the southern and middle part of the Tamil Nadu is going high and reduce
the risk of transportation. In view of the above and to reduce cost of hazardous waste
transportation and minimize the risk during transportation.
3.3. Justification of Project
The present Hazardous Waste TSDF at Gummidipoondi is catering the needs of all
industries present in Tamilnadu. As per MOEF Technical EIA guidelines manual of
TSDFs there are around 3067 industrial units in the state of Tamilnadu generating around
481760 MTA hazardous waste (land fillable waste 291790 MTA; Incinerable Waste 1173
MTA; Recyclable wastes 168796 MTA), where as the existing secured landfill capacity is
for 100000 MTPA. In order to meet the deficiency for treating the additional land fillable
and recyclable waste, a Common Hazardous Waste Management Facility is proposed in
Thoothukudi district to meet the demand of districts in and around.

3.10.7 Waste Disposable Operations
3.10.7.1 Waste Stabilization
Waste stabilization is designed to convert industrial wastes in the form of liquids, semi-solids
or reactive solids into low leachable materials that can be deposited into a secure landfill.
The stabilization operation will be carried out for all waste that requires this to minimize their
contaminant leaching potential. This will change the nature of these wastes to a less
hazardous category. Stabilization involves the immobilization of leachable materials by
fixation as non-reactive solids. The treated wastes shall be assessed for compatibility with
other wastes before being landfill and for compatibility with the HDPE and the pipe network.
The term stabilization covers a number of mechanisms including:
Immobilization / Chemical Fixation – the chemical binding of contaminants
within a cementing structure to reduce the mobility or leachability of the waste.
Encapsulation – the occlusion or entrapment of contaminant particles within a
solid matrix.
Solidification – the conversion of slurries that do not readily de-water, into solids
by addition of adsorption agents.
Typical reagents that would be used for the stabilization process include cement, lime, fly
ash, bentonite clay, saw dust and other. Where required sodium silicate solution would be
used as an additive binding agent. The reagent to be used for stabilization shall be decided
depending upon the type of the waste to be stabilized, price and availability. These regents
shall generally be Stored in sufficient quantities. The Infrastructure proposed for the
stabilization unit would include:
Storage facilities for regents
Tanks/Drums for storage of reagents as required
Stabilization bins for mixing the wastes
Earth moving equipment for movement of wastes and mixing.
Place for curing the treated waste
Trucks for hauling the wastes.
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
19RamkyEnviroEngineersLimited
Treatment facility utilizes a range of techniques and processes designed to change the
physical, chemical or biological characteristics of the waste. This may include changing the
composition so as to neutralize the waste, to recover energy or natural resources from the
waste, to render the waste non-hazardous or less hazardous, safer to transport, store, or
dispose off or to reduce its volume. Typical operations at Stabilization unit are as follows:
Reception of Waste
Reagent addition
Mixing
Curing
Analysis of the stabilized wastes
Approval by the laboratory for disposal
Transfer of the waste materials to the truck
Disposal in the secured landfill
Application criteria: A study of the waste characteristics carried out as an integral part of
the project indicates the following applicability to the process described below in Table 7.

3.10.7.2Guidelines adopted for TSDF Operations
Based on the quantities available the following general information could be inferred:
The following general guidelines shall relate to daily activities associated with the operations
of TSDF:
The facility shall operate only during day light hours throughout the year.
The landfill will be staged in cells so that the minimum practical area of waste is
exposed and maximum practical area of waste has the final cap in place i.e.,
progressive filling and capping of the landfill ensuring minimization of infiltration of
wastes.
The Weigh Bridge at the main entrance will record all movements and weights and
receive waste tracking receipt as required by the waste manifest system.
The standpipe forming part of the leachate collection system shall be checked
regularly for the presence of leachate. Once leachate is detected it shall be regularly
pumped out and transferred to the leachate treatment facility on-site. The level of
leachate in the standpipe shall not be allowed to rise above the level of the leachate
collection system.
Materials Safety Data Sheets (MSDS) for every chemical used or handled at the
landfill shall be provided on the premises.
Monitoring and auditing of the facility shall be performed on a periodic basic.
Met-station shall be installed with continuous recording system.
A security system shall be maintained to avoid trespassing & hazard to public.
Once a waste is received at the TSDF, a sample of waste shall be collected, at the
sampling bay/temporary storage facility and shall undergo laboratory analysis based
on which its pathway of treatment/ disposal shall be determined.
A waste manifest system shall be developed in accordance with the requirement of the
regulatory agencies to cover the transportation of the waste to TSDF and to provide
for record of waste manifestation. The manifest system shall include details of the
waste generator, waste transporter, quantity of waste, characteristics of waste,
description, consistency of waste in terms of physical state and waste category
number as per HW (M&H) Rules, 2003.
Each load of waste arriving at the facility shall be located properly and logged to
identify its pathway of treatment/ storage/ disposal.
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
21RamkyEnviroEngineersLimited
An inventory shall be maintained at the arrival and departure dates of waste loads in
and out of the intractable waste storage area.
3.10.7.3 Landfill Design
The landfill will be designed and constructed as a secure facility to contain the waste material
and any leachate, which is formed by the entrapped moisture or by infiltration of rainfall. To
meet these requirements the base of the landfill has been designed as an engineered liner
constructed prior to the placement of waste and also an engineered capping over the surface
after completion of filling to minimize the infiltration of rainfall. The cross section of the
landfill meeting MOEF Guidelines is given in Figure 4.
The base liner of the landfill containment system is proposed to be a double composite liner
with synthetic geo-membrane plus clay. Adequate leachate collection system shall be
incorporated at the base to collect and remove the leachate. These shall incorporate HDPE
pipes embedded in drainage layers of sand/ gravel and /or geonet/ geotextile. The composite
liner (Secondary liner) shall comprise of a 0.45 mm thick clay compacted to a permeability
less than 10 –9 m/s and above this shall be a HDPE liner with permeability less than 10 –14 m/s
above which a complete drainage system shall be placed. Above the secondary base liner
shall be placed a primary liner comprising of primarily clay layer and HDPE membrane
which will prevent infiltration into the secondary layer. A leachate collection and removal
system shall also be placed over the primary liner to collect and remove any leachate
generated by infiltration of precipitation or by the moisture entrapped in the waste. This
makes the secondary system to serve as a leak detection system and an early warning of
potential future liabilities to necessitate action for remediation. Above the drainage system of
the primary liner shall be placed a geo-textile filter to act as a filter/ barrier between the waste
and the drainage system. This entire system would make the base liner a double composite
liner meeting the national laws.

Figure 4: Landfill Cross Section
Clay Liner consists of a varying proportions of hydrated aluminum silicates (e.g. kaolnite,
bentonite, illite and montmorillonite) which, when properly compacted, form a soil mass with
a very low hydraulic conductivity. The clay material for use as the liner at this landfill shall
be analyzed and permeability testing shall be carried out to ascertain its low permeability.
Design permeability of the clay liner has been fixed at 10 –09 m/s and with availability of clay
liner; we will be able to achieve better results than the design values. Placement of clay liner
shall be most critical in terms of its efficiency of functioning. Clay should be placed in layers
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
23RamkyEnviroEngineersLimited
not exceeding 200-mm and shall be compacted to attain the required permeability. The clay
layer after attaining the 0.45m thickness should be then checked for its permeability. Further
to this, clay shall be kept moist to ensure that it does not dry up and cause cracks to the lining
system. To ensure this we intend to keep the clay for the purpose at +4% wet of optimum
moisture content.
Synthetic Liners consists of various synthetic flexible membrane liners have been
considered for use as the primary liner at the proposed landfill. Both Poly-Vinyl Chloride
(PVC) and High – Density Polyethylene (HDPE) liners are generally suitable for this landfill.
Tensile strength is a fundamental design consideration in order to assess the ability of the
liner to resist uniaxial and biaxial strains, which occurs in the landfill. Another stress strain
consideration is the coefficient of thermal expansion.
Considering various membrane properties it is decided to use HDPE liner with appropriate
thickness as primary liner for the base of the landfill. HDPE was selected for the following
reasons:
Adequate strength to withstand mechanical strength during construction, placement
and operations.
Acceptable weathering performance.
Superior physical properties under chemical and environmental exposure to wastes
Capability to withstand the seaming process.
The hydraulic conductivity of HDPE is of the order of 0.5 * 10 –16 m/sec, which is effectively
impermeable. Construction of the seam welding process shall be subjected to strict QA/QC
measures to ensure the integrity of the liner.
Secure Landfill is the final placement area for land fillable hazardous wastes which are
treated or wastes does not require treatment. Waste directly or after treatment will be
disposed in the landfill as per the laboratory advice. Waste will be spread in the landfill using
heavy earth machinery and then compacted using vibro compactor. At the end of the landfill
operations 10 – 15 cm soil cover is placed as a daily cover.
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
24RamkyEnviroEngineersLimited
During rainy season a flexible HDPE sheet cover shall be placed over the uncapped area of
the landfill minimize infiltration of rainfall into the landfill; the rain water shall be diverted to
join the surface water drains. At the end of the total landfill operations the final capping shall
be done using composite liner with clay and synthetic geo-membrane, with vegetative soil
cover grass cover.
3.10.7.4 Leachate Collection/Treatment and Disposal
Leachate collection and removal shall be provided above the geo-membrane in two layers
viz., the primary and the secondary liners. The primary liner shall serve as leachate collection
and removal system, while the secondary liner shall serve as leak detection system and a
signal of potential liabilities in terms of environmental pollution. Leachate shall be collected
by a network of lateral and header pipes embedded in a drainage layer, all of which shall
eventually drain into a leachate collection sump. The collected leachate shall be transferred to
a leachate treatment system.
The leachate collection system in an engineered landfill takes the form of an under-drain
beneath the waste material it is required to ensure there is no more than a limited head of
pressure above the base liner to cause leakage of liquid from the base of the landfill. The
design maximum pressure head in the proposed landfill shall be limited to 300mm.
Drainage is affected by a layer of about 300mm thick of graded sand/gravel having a high
permeability. Within this layer a network of HDPE pipes are placed to collect leachate and
conduct it quickly to the collection sump for removal from landfill. The pipes are typically
perforated only over the upper half to allow the leachate to enter the pipe and thereafter to be
contained within the pipe network system. The layout of the pipe network generally includes
sufficient redundancy to ensure that if a blockage occurs somewhere in the network the
leachate simply backs-up a little then flows into the system a little further up-gradient. Two
layers of the leachate collection system shall be provided one over the other. Slotting area of
the pipe shall be done only on the top 120o portion of the pipe and to an extent of 100 cm2 per
running meter of the pipe.
The key design features of the leachate collection system to be installed at the proposed
landfill comprise the following:
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
25RamkyEnviroEngineersLimited
A network of semi perforated HDPE pipes laid out directly over the primary and
secondary liners and graded towards the collection sump at no less that 2% slope,
with a slotting area of 100 cm2 per running meter of the pipe.
A drainage layer 300mm thick of graded sand/gravel placed over the entire base of the
landfill, covering the pipe network.
A geo-textile placed over the primary liner serving the purpose of filter/ barrier
between the waste and the drainage media.
The pipe shall have sufficient strength to withstand the load imposed by the overlying
waste and the earth moving activities associated with the placement and the
compaction of the waste (Min 6 Kg/ Sq.cm).
3.10.7.5 Drainage of Surface Runoff
Network of open channels shall be designed and constructed around the landfill to intercept
surface runoff of rainwater and divert it around the facility and collect it for the use at the
facility or for disposal. Storm water collected on the landfill site will be directed to a first
flush retention pond which shall be designed for a sufficient capacity to cover a 1 in 100
years 10 minutes storm event. In particular the storm water system will be designed and
implemented to prevent surface runoff entering the landfill and thus minimizing the leachate.
3.10.7.6 Wastewater Treatment
Leachate collected from Secured Landfill will be treated in a solar evaporation pond/forced
evaporation. The dry residue from the solar evaporation pond/forced evaporation will be
handled as a solid waste and will be disposed in the landfill. The domestic sewage will be
treated in a septic tank/ soak pit arrangement.
3.11. Alternate Fuel & Raw Material Facility (AFRF)
The disposal of hazardous waste creates major economic and environmental problems. The ideal way of handling and disposal of hazardous waste is to look for options such as reuse, recycle and / or recovery. In line with this concept utilization of hazardous waste as a fuel or raw material in the manufacture of cement is one of the best options. Central Pollution Control Board (CPCB) in the year 2010, issued “Guidelines on Co processing in Cement/Power/Steel Industry” to encourage utilization of selected hazardous waste in cement
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
26RamkyEnviroEngineersLimited
kilns as a fuel or raw material while protecting the environment from the control of emissions and without impacting the quality of cement.
3.11.1. Wastes Handling in AFRF
Despite co-processing having inherent advantages, a careful approach is desired in view of
the hazardous nature of the substances that are handled in the process from the point of
i. Selection of right materials
ii. Transportation of waste
iii. On-site storage
iv. Handling & Disposal
v. Emission control
vi. Compliance, Health & Safety management
The hazardous wastes for co-processing need to be handled in an environmentally sound
manner avoiding the possibilities of contaminating the nearby environment and eliminate the
chances of accidents. CPCB has identified and prescribed suitable wastes for co-processing in
cement kilns.
3.11.2. Categories of Wastes Handled
The following are the categories of hazardous wastes / substances for which regular
permission has been granted by CPCB for co-processing in cement industries,
1. Hazardous Wastes
a. Paint sludge from automobile sector
b. Petroleum refining sludge
c. TDI tar waste
d. ETP sludge from M/s BASF India Ltd.
2. Other Wastes
a. Plastic wastes
b. Tyre chips
The hazardous wastes other than which are listed in the above mentioned not recommended
list, should possess the following characteristics as a minimum for co-processing in the
cement kilns.

• Explosives • Corrosives • Mineral acid wastes • Radioactive wastes • Unsorted municipal garbage
In view of the above potential for reuse of hazardous waste in the cement industry, IWMA envisages to set up Alternate Fuel and Raw Material Facilities (AFRF) at SIPCOT, Thoothukudi.
3.11.3. Methodology of waste handling
The principle concept of AFRF is to pre-process the waste at TSDF to make it directly suitable to utilize in cement kilns either as raw material or fuel. The pre-processing like blending / mixing / calorific value enriching etc., will homogenize the wastes received from different industries and bring the pre-processed waste characteristics in line with concentration limits as prescribed by CPCB. AFR Facility at TSDF shall help the hazardous waste generator in providing one stop solution for all the hazardous wastes generated at their end and at the same time help cement industry in eliminating the transport, pre-processing and other associated activities at their and facilitate both of them to concentrate in their core business of manufacturing activity. The methodology of operations is as follows:
1. Waste Characterization: 2. Waste Transport from HW generator 3. Pre-processing at – AFR Facility 4. Waste Transport to Cement Industry
3.11.3.1 Waste Characterization:
The waste received from the generator shall be subjected to comprehensive analysis as per the Hazardous Waste (Handling, Management &Transboundary) Rules, 2008. The disposal pathway of the waste shall be first looked for the possibility of converting the same to be useful for co-processing otherwise it shall be opted to dispose by means of secured landfill or incineration. The protocol for the comprehensive analysis is presented in the Annexure – II. The following laboratory infrastructure required for the AFR Facility
S.No Parameters Instruments Required for Testing 1 pH pH meter 2 VOC PCB/PCT Gas Chromatograph 3 TOC TOC Analyser 4 CaO, SiO2,Al2O3, Fe2O3, SO3 Inductive Couple Plasma

3.11.3.2 Waste Transport from the Generator
The waste shall be collected from the generator (industry) in closed and spillage proof
containers. A label as per the HW Rules (enclosed as Annexure -III) shall be affixed on the
container and transported in the dedicated trucks duly following the 6-copymanifest system
(Manifest form is enclosed as Annexure – IV). The driver also carries the TREM card
(enclosed as Annexure – V) and hands over to the TSD Facility at the time of waste
reception.
Covered, pneumatically operated and dedicated vehicles are used for the transportationof
waste from the generator to TSDF as well as pre-processed waste to cementindustries for co-
processing. Drums are handled using forklift.

3.11.3.3 Finger Print Analysis
The waste suitable for co-processing shall be directed to AFR facility for pre-processing.
Strong oxidizers generally are considered to be incompatible with many organic substances
because of the potential for dangerous reactions. Chlorates, per chlorates and other strong
oxidizers are potentially incompatible with alcohols, halogenated hydrocarbons, other
reactive organic compounds and solvents, and other flammable and combustible wastes. The
potential consequences of mixing such incompatible materials are fire, explosion, or violent
reaction. Compatibility Criteria shall be followed at all stages of operations.
3.11.3.4 Pre Processing of Wastes
The waste shall be received at TSDF and verified for the necessary documents and then the
same shall be weighed at the TSDF and shall be subjected to a quick verification testing
called finger print analysis as per HW Rules. The protocol for the finger analysis is presented
in the Annexure – VI. The waste suitable for co processing shall be directed to AFR facility
for preprocessing.
Strong oxidizers generally are considered to be incompatible with many organic substances
because of the potential for dangerous reactions. Chlorates, perchlorates, and other strong
oxidizers are potentially incompatible with alcohols, halogenated hydrocarbons, other
reactive organic compounds and solvents, and other flammable and combustible wastes. The
potential consequences of mixing such incompatible materials are fire, explosion, or violent
reaction. Compatibility Criteria shall be followed at all stages of operations.
The following chart helps in understanding compatibility between various hazardous
chemicals and compounds

The waste having rich mineral content as per CPCB guidelines with special reference to lime,
silica and alumina shall be checked for other parameters and they will be adjusted to desired
levels as per the possibility and sent to cement industry as an alternative raw material.
The wastes which are principally candidates for incineration shall be checked for calorific
value, halogens, sulphur and other heavy metal content. These wastes are fit for converting
them as alternative energy material for cement industry/other suitable industry. The calorific
value shall be enriched using rice husk /high calorific wastes or lowered by mixing neutral /
low calorific waste materials to make it optimum around 4000 K Cal/ Kg.
There are three types of wastes that are to be processed
i. Solid wastes
ii. Semi-Solid/ Tarry wastes
iii. Liquid wastes
i. Solid Wastes
Based on the characteristics of the potential solid wastes that can be converted as alternate
fuels suitable for co-processing in cement plants are taken into a mixer / blender. A solid
blend is prepared by adding some additives to adjust all relevant parameters.
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
32RamkyEnviroEngineersLimited
The first step of preparing solid blend is selection of wastes suitable for mixing / blending.
The segregation of waste according to their pH & calorific value helps in it. Source materials
for solid substitute fuel include Paint Sludge, Oily Filter Cake, Spent Carbon, Organic waste,
Tarry waste, Biomass, Resin, Distillation Residues, Grease etc. Assortment of waste is done
according compatibility criteria. A general waste selection criteria for high calorific value
fuel is Low moisture content, high LOI & TOC, high calorific value, good compressibility,
less ash content, nontoxic, less pollutant, sustainable combustion.
After selection the waste is mixed with binders. Some common binders which can be used for
blending are rice husk, press mud, bagasse, saw dust, scrape of coconut, coal dust, lime,
silicates, epoxy resins, fly ash etc. Binders should have following properties are Easily
available, Cheap in cost, Produce strong final agglomerates, permanently bond particles,
withstand the rigors of storage, handling, packaging & shipping.
The addition of strength increasing additives such as latex, pulp from the pulp & paper
industries, paper, cardboard, acrylic copolymers, starch, starch derivatives, vinyl derivatives,
cellulose, cellulose derivatives, peat moss etc. plasticizers to improve the adherence &
plasticity; inorganic components like bentonite or other types of clay, and cement are optional
components to provide different characteristics to the blended product. Final pre-processed
waste mix may contain 90% of waste and 10% binders

33RamkyEnviroEngineersLimited
Typically mechanical mixer or a solid material blender shall be used for mixing / blending
the waste. In general incinerable wastes are received in drums, containers and occasionally in
bags or bulk. A Cart Dumper shall be used for loading of the waste into the blender which is
placed at elevated location. The outlet of the blender shall be opened into a container placed
below the blender.
Pre Feasibility Report for the Proposed CHWTSDF in SIPCOT Thoothukudi by IWMA
34RamkyEnviroEngineersLimited
The laboratory advises the type of wastes that can be mixed and / or various reagents /
additives that are required to be added to make final blend to get the prescribed standards for
co-processing in cement plants.
Samples shall be taken after the blending process and subjected for confirmation from the lab
as per acceptability criteria otherwise the process will be continued to fine tune to get the
whole matrix reaches to the acceptable criteria. Then the waste will be unloaded, packed and
sent to cement plants.
ii. Liquid Wastes
In general liquid wastes are received in drums or tankers. The wastes after necessary pre
quality check (FPA), they will be stored in the day tanks as per their compatibility. The
suitable and compatible wastes are taken into a reaction vessel (typically 5 KL capacity) and
necessary fine tuning will be done for achieving necessary characteristics as desired for the
co-processing requirements for cement plants.
The reaction vessel is a jacketed vessel equipped with necessary blending arrangements for
mixing and homogenization of various reagents and wastes. It is also equipped with cooling
system in order to balance any small degree of exothermic reactions.

35RamkyEnviroEngineersLimited
iii. Semisolid / Tarry Wastes
Certain wastes are neither liquids nor solids but they are in semisolid state. We in general call
them as sludge. Based on the viscosity of the waste, we can categorise them as free flowing,
sludge, heavy sludge etc. In addition certain wastes are tarry or sticky in nature and
sometimes it is difficult to remove from the drum.
Semisolid wastes are handled in two ways depending on the physical characteristics and
viscosity.
a. The wastes which are free flowing or pump able in nature are processed as per
liquid type wastes
b. The wastes which are heavy sludge, sticky or tarry type wastes are processed as per
solid type wastes.
A flow chart showing the processes involved for all three types of wastes suitable for Co
processing is given below:

9.0. ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)
The land area of 20 acres for the proposed project is adequate exclusively for the waste
generated in and around the project area. The location of the project is within the SIPCOT
industrial area and complying to the CPCB site selection criteria for developing CHWTSDF,
hence will not pose any social or other issues.
The Project is also envisaged to set up AFR Facility so that the incinerable waste can be
preprocessed and sent to cement plants for co-incineration. The project is economically and
technically viable because this project helps the industrial waste generators in and around
Thoothukudi in reducing their waste transportation cost. At the same time the Project also
envisages the subsidies from the Central and State Government for developing common
TSDFs.

Project Benefits
From the proposed project the major benefits, include improving the degraded environment by establishing an Integrated Common Hazardous Waste Treatment, Storage, and Disposal Facilities.
The proposed project facilitates better management of the industrial wastes. It will be the showcase for other states for management of hazardous waste with
additional benefit of green and clean Environment. It minimizes the pollution load on environment from industrial hazardous waste Compliance with prescribed regulatory norms which in turn avert the risk of closure
on account of violation of rules It reduces the number of hazardous waste dump sites in the area and also eliminates
the pollution potential The management of wastes is relatively easier & economically viable at common
facility. Cost of environmental monitoring is less at common facility Reduced environmental liability due to captive storage of hazardous waste in the
premises of industries Better occupational health and safety at individual industry level Prevention of natural resource contamination thereby improving overall
environmental status of the region

rules made thereunder, shall also be applicable for disposal of leachate into sewage
treatment plant, common effluent treatment plant, Inland surface water bodies or
coastal areas.
2. For each CETP and its constituent units, the SPCB/PCC shall prescribe standards as
per the local needs and conditions; these can be more stringent than those prescribed
above. However, in case of clusters of units, the SPCB/PCC may prescribe suitable
limits.
3. Leachates having high COD shall be concentrated through evaporation (forced) and
fed to the incinerator of the integrated TSDF in view of its high calorific value, and
the residue ash shall be disposed off in their secured landfill.
4. The Bioassay test shall be substituted by ‘Fish Toxicity’ test, and a dilution factor of 2
(two) may be considered.
