Pre-Feasibility Report

1. Executive Summary Waste to Energy (WTE) is the sum of processes that produce electric energy from waste.

Nowadays it has also become a safe and favorable form of energy recovery from the

environmental point of view. As such, it is currently regarded as an essential element in

the mechanism of integrated waste management, in all industrialized countries. Waste

to - energy provides the fourth "R" in a comprehensive solid waste management

program: Reduction, Reuse, Recycling, and energy Recovery.

To meet the demand of the space for proper treating and disposal of the municipal

waste in twin cities of Hyderabad, Secunderabad and its surrounding municipal areas,

Greater Hyderabad Municipal Corporation (GHMC) is proposing to take up

establishment of MSW based waste to energy power plant (2x24 MW) at its existing

Integrated Municipal Solid Waste Management Project (IMSWMP).

Hyderabad Integrated Municipal Solid Waste Limited (HiMSW Limited), a subsidiary of

Ramky Enviro Engineers Limited (REEL) has entered into a Concession Agreement with

GHMC for development of IMSWMP on 27th February 2009. GHMC has obtained

Environmental Clearance from SEIAA, AP vide letter dated 20.06.2012 for establishing

IMSWMP for processing MSW of 5500 TPD in phased manner which included waste to

energy power plant of 2 x 24 MW.

The SEIAA later on informed that the approval of waste to energy plant with a capacity

of 2 x 24 MW to a total of 48 MW was not within its purview. Upon which, GHMC, has

decided to reduce the same to 19.8 MW so that the same falls within the purview of

SEIAA and accordingly the minutes of the meeting held by SEAC dated 27.09.2013, has

revised the capacity to be 19.8 MW for the proposed waste to energy project.

The GHMC, later decided to reduce the capacity of the power plant to 19.8 MW and

submitted to SEAC vide letter dated 11.09.2013. SEAC in its subsequent meetings has

recommended for issue of amendment to EC with respect to power plant of capacity of

19.8 MW and the same was approved by SEIAA in its minutes of meeting dated

23.10.2013. SEIAA has issued amendment to environmental clearance vide its Order No.

SEIAA/AP/RRD-111/2009-5364 date: 25.10.2013, reducing the capacity of the MSW

based power plant to 19.8 MW.



2. Introduction of the Project

2.1 Identification of Project and Project Proponent

HiMSW Limited is establishing an integrated MSW project for Greater Hyderabad

Municipal Corporation (GHMC) at Jawahar Nagar to handle MSW in compliance with

MSW Rules 2016. The main objective of the proposed Integrated Municipal solid waste

processing is to collect 100% of MSW generated in the city limits and to dispose-off the

same through a most scientific and productive disposal through a combination of

processes) such as compost, pre-sorted waste and also Waste to Energy. The proposed

capacity of the WTE plant will be 4 x 600 TPD in a phased manner.

Ramky Enviro Engineers Limited is a reputed waste management company in the

country with vast experience in the Solid Waste Management (SWM) sector. HiMSW

Limited is a group company of the "Ramky Group" based at Hyderabad, which is

emerged as India's largest in the environmental sector and has pioneered the art and

engineering of SWM in India. It has established itself in the leadership position in the

country in the field of environment and infrastructure.

2.2 Brief Description of Nature of the Project

HiMSW Limited intends to set up MSW base waste to energy power plant (WTE) in a

phased manner. There will be two blocks of waste to energy plants - each comprising of

2 units of 600 TPD MSW combustors with 24 MW aggregate power generations. Thus, it

is proposed to install total 4 units of 600 TPD MSW combustors with an aggregate power

capacity of 48 MW in total. It will be implemented in phases

2.3 Need for the Project and its Importance to the Country and Region

The percentage of India's population living in cities and urban areas has increased over

the years since independence, showing the rapid pace of urbanization. This will

accelerate even further and by the year 2021 over 40% of Indians are expected to

reside in the urban area. This has been fuelled by rapid growth in industrialization,

commercialization, development of secondary and tertiary sectors of economy and

mass migration. The progressively improving standards of living, rapid urbanization and

the wasteful consumer attitudes have resulted in the increase of quantities of

municipal wastes to be-handled.

The problem of municipal solid waste management has acquired alarming dimensions in

India, like any other developing country, is fraught with many inadequacies. In addition,

it is a major economic burden on local Government & furthermore, open burning of

MSW adversely affects the environment by emitting pollutants to the atmosphere. Thus,

it is increasingly felt that the first step towards sustainable waste management

programme is to quantify factors affecting environmental quality factors affecting



environmental quality pertaining to MSW. The report of high power committee on urban

solid waste management in India stated that urban solid waste management continues

to remain one of the most neglected areas of urban development in India. Furthermore,

the disposal of the waste is by unplanned and uncontrolled open dumping at the landfill

sites.

The urban areas of India produce about 30 million tons of solid waste from household

and commercial activities every year. It is estimated that there is a potential for

generating about 1,000 MW of power from MSW in India. If this potential is to be

effectively used, it will not only contribute substantially to the overall power generation

capacity but will also give a good return on investment, apart from improving the

environment.

2.4 Demand Supply Gap

Rapid growth of industries and commerce in India necessitates uninterrupted power

supply. Therefore, all options need to be explored to generate power from conventional

and non-conventional sources. MSW provides an opportunity of tapping potential energy

to meet part of the energy demand of the country.

2.5 Imports vs. Indigenous Production

At present there are no plans of importing the MSW, only indigenously produced MSW

will be used for proposed WTE power plant. However, in future if any MSW is taken from

long distance the same will be informed to the concerned authorities.

2.6 Export Possibility

At present there are no plans of exporting the MSW to other countries as it is not techno

economically feasible, however in future if it is economically viable the same will be

informed to the concerned authorities.

2.7 Domestic/Export Markets

The power generated from the proposed waste to energy plant will be used for captive

requirement the excess will be connected to the grid.

2.8 Employment Generation (Direct and Indirect) due to the Project

Around 400 people will get direct employment by the proposed project and around 100

people will get indirect employment.



3. Project Description

3.1 Type of Project including Interlinked and Independent Projects, if any

The proposed project is a municipal solid waste based waste to energy power plant

which is a part of the integrated municipal solid waste management project, which

obtained EC for processing of 5500 TPD of municipal solid waste. The schematic

representation of processing MSW through waste to energy is shown in Figure 1.

3.2 Location (Map showing general location, specific location, project boundary and

project site layout) with coordinates

The site is located at 17° 31' 10.49" N latitude and 78° 35' 07.52" E longitude in

Jawaharnagar Village, Kapra Mandal, Medchal District, Telangana State. The location map

of the site is shown in Figure 2 and site layout is shown in Figure 3.

3.3 Size or Magnitude of Operation

The area allocated for MSW based power plant is 31.5 acres. The capacity of the power

plant is 48 MW operating in two phases (2 x 24 MW). The proposed project is sized for a

capacity of 2400 TPD MSW with four (4) boilers of 600 TPD capacity and two (2) units’

turbo generators, each of 24 MW to be implemented in phased manner. The waste

based power plant is designed to combust 2400 TPD of MSW with the gross calorific

value (GCV) 2024 kcal/kg.

3.4 Project Description with Process Details (A schematic diagram/ flow chart showing

the project layout, components of the project etc. should be given)

The proposed MSW based power plant consists of four number of steam generators

capable to burn 600 TPD of segregated MSW in each boiler, with super heater steam

outlet parameters of 45 kg/cm2, 400 C and two 24 MW extraction cum condensing turbo

generator.

The turbo generator capacity is arrived based on the actual steam quantity available to

generate power, with required margins to take care of the valve wide open (VWO)

conditions of the turbo generator and to meet various operating and upset conditions of

the power plant. The steam generator is equipped with complete required system like air

and flue gas system, fuel and ash system, feed water and steam system, dust collection

system, soot blower system, steam and water analysis system, boiler draft system,

Instrument air system, electrical system, instrumentation and control system, etc.

Each turbine will be a single bleed cum condensing machine. The steam required for the

de-aerator is taken from the bleed of the turbine. Air cooled condenser (ACC) is identified

as the condensing equipment. Steam required for the ejector and gland sealing is about



350 kg/h at 10.0 kg/cm2, is taken from live steam line through pressure reducing & de-

super heating station (PRDS).

The power plant cycle will be provided with a de-aerator serving the dual purpose of de-

aerating the feed water as well as heating the feed water with the bleed steam drawn

through the turbine. The de-aerator considered is a floating pressure type. The feed

water management program shall ensure the supply of good quality makeup water to the

system. In the proposed power cycle, from the steam supplied to the turbine, about 98%

will come back as the condensate from the ACC to the steam generator, through the feed

water heating system (de-aerator). The complete make up required for the plant

operation will be obtained from HMWSSB/borewells within site.

Makeup of required quality is considered from the water treatment plant. The makeup

for the cycle will be added in the condensate hot well and the quantity of makeup will be

controlled by the hot well level control system. Well engineered Fuel feeding and ash

handling system is considered for this project.

The power generation will be at 11 kV level. After meeting the power plant internal

consumption, the remaining power will be stepped up by a step-up transformer and

exported to the TSTRANSCO grid. The complete plant instrumentation and control

system for power plant shall be based on distributed controlled system (DCS) philosophy,

covering the total functioning requirements of measuring, monitoring, alarming and

controlling, logging, sequence interlocks and equipment protection etc.

3.5 Details of alternate sites considered and the basis of selecting the proposed site,

particularly the environmental considerations gone into should be highlighted.

No alternative sites were considered. The proposed project will be developed / operated

within the existing IMSWMP only.

3.6 Raw material required along with estimated quantity, likely source, marketing area

of final products, mode of transport of raw material and finished product.

The raw material for the proposed project is municipal solid waste, which is having the

certain calorific value suitable for power generation. The total MSW of the proposed

project surrounding areas is getting scientifically segregated, treated and disposed at the

site.

3.7 Resource optimization/recycling and reuse envisaged in the project, if any, should

be briefly outlined.

The proposed project is based on the reuse of the municipal solid waste (RDF) which is

having certain calorific value generated in surrounding areas of the project area.



3.8 Availability of water its source, Energy/power requirement and source should be

given

The process water requirement for the proposed project is 1425 KLD. Out of that cooling

tower makeup is 750 KLD and DM plant/Boiler makeup is 675 KLD. The total power

required for operations is 7200 kW and the construction power / commissioning power /

backup power source will be met from TSTRANSCO.

3.9 Quantity of wastes to be generated (liquid and solid) and scheme for their

management/disposal.

The wastewater of 438 KLD will be generated which includes 262 KLD from cooling tower

blow down 106 KLD from boiler blow down and 70 KLD from DM regeneration.

5.4 Assessment of Infrastructure demand (physical & social)

There will be a minimum influx of people to the area due to the proposed project, as the

major manpower will be employed from the nearby villages. Hence the infrastructure

available is sufficient to accommodate the demand.

5.5 Amenities/Facilities

All the amenities/facilities like security room, administrative building, toilet block, etc.,

are present within the existing IMSWMP and the same will be used for the proposed

MSW based waste to energy power plant.



6. Proposed Infrastructure

6.1 Industrial area (processing area)

The site is well established with all the facilities as it is an existing IMSWMP operating

from last few years, previous to this the area was used as an open dumping area of MSW.

6.2 Residential area (non-processing area)

No residential area is proposed within the project site

6.3 Greenbelt

A 15 m wide greenbelt was developed all around the existing IMSWMP and the total area

allocated for greenbelt development is 7.12 acres out of 351.12 acres. In addition to this

existing old dump was capped and brought under green cover and in future completed

sanitary landfill facility will be brought under green cover once the landfill area is

completely occupied by MSW. The list of plants proposed for greenbelt is given in Table

3.

6.4 Social infrastructure

Social infrastructure facilities like hospital, school, college, temple, etc., are available in

area, as the proposed project is part of the GHMC area.

6.5 Connectivity (traffic and transportation Road/Rail/Metro/Water ways etc.)

The site is well connected with all the transportation facilities from the nearby places. SH

1 is located at a distance of 6.6 km (W) and NH7 is at a distance of 10.8 km (W). The

nearest railway station is Cherlapally railway station is at around 7 km (S) and

Secunderabad railway station is at around 13 km (SW). The nearest airport is Rajiv

Gandhi International airport is at around 35 km (SSW).

6.6 Drinking water management (Source & Supply of water)

The drinking water required for the proposed project will be taken from

HMWSSB/borewells within site.

6.7 Sewerage system

The domestic waste water generated from the proposed project will be sent to septic

tank followed by soak pit. The process water will be treated and reused for various other

uses.

6.8 Industrial Waste Management

The total ash generated from the proposed MSW power plant will be maximum of about

244550 TPA (for both blocks of 24 MW WTE put together). Dry fly ash collected from the

bag filter hoppers and the economiser hoppers and the ash collected from the furnace



bottom, Evaporator / super heater bottom hoppers can be used for landfilling, cement or

brick manufacturing.

The reuse potential of MSW incinerated ash in the light of toxicity and compressive

strength is prone to huge variation due to the heterogeneous composition and higher

moisture content of the solid waste. Higher concentration of heavy metals and some

hazardous chemicals are observed in the fly ash of existing MSW fired WTE facilities. The

bottom ash collected from the furnace bottom is observed with relatively less

concentration of hazardous material. The MSW ash contains non-combustibles such as

metals, glass, concrete, brick, etc. The ash is not preferred for any other use and is

disposed in landfills.

6.9 Solid waste management

Domestic solid waste of 80 kg/day generated from the admin building and workshops will

be sent to the composting plant after proper segregation.

6.10 Power requirement & supply/ source.

The total power required for operations is 7200 kW and the source is from TSTRANSCO.

Once the power plant will be fully operational the power requirement will be met from

the same and excess will be interconnected to TSTRANSCO substation at Malkaram.
