MUNICIPAL SOLID WASTE UTILIZATION

Created during the decomposition of organic substances,

landfill gas consists of methane, carbon dioxide, and

nitrogen. The controlled collection and combustion of

this problem gas is an indispensable step in the modernoperation and re-cultivation of a landfill site.

In addition, the high calorific value of landfill gas makes

it a viable fuel for gas engines that can be effectivelyused for power generation.

Ideal solution for using your waste gas as an energy

source. http://www.epa.gov/osw/nonhaz/municipal/

HOW IT WORKSMunicipal waste contains about 150 to 250 kg of

organic carbon per ton.

These substances are biologically degradable and are

converted by microorganisms into landfill gas. Stable,

anaerobic methane fermentation begins one to two years

after the waste is deposited in the landfill.


4/18

HOW IT WORKS

Following a simple rule of thumb

1 million tons of deposited municipal solid waste will

produce landfill gas over a twenty-year periodan

amount sufficient to fuel a gas engine capacity of 1

MW.


5/18

Perforated tubes are drilled into the landfill body andinterconnected by a pipe work system.

Using a blower, the gas is sucked from the landfill,

compressed, dried and fed into the gas engine.

In most cases, the generated electrical power is fed into

the public grid.

Since there is no buyer for the heat output in most cases,

the thermal energy could be converted into furthe

electrical power.

HOW IT WORKS

PROJECT DESIGN AND LAYOUT

Required land is about 2 acres.

SOURCES OF FINANCE

Is expected to catalyze an investment of aroundover 60 lacks from the private sector to finance theprojects. And we take the help of IDBI bank forfinancing.

The economic efficiency of projects is typicallyhigh with an economic internal rate of return (EIRR)in the 25%30% range and financial internal rate ofreturn (FIRR) in the 10%

15% range.


9/18

ESTABLISHMENT OF PROJECT

Leasing of government land for functioning of theproject.

Establishing of project inside the city.(near theKanan Vihar-1)

Required land is about 2 acres.


10/18

RAW MATERIAL REQUIREMENT

Municipal solid wastes.

Every day required 1000 TONS of wastes taken from BMCwhich is free of cost & free delivery to the site.

HUMAN RESOURCE PLANNING

2 supervisor required for maintain ace and supervision in1 shift.

2 supervisor required for maintain ace and supervision in

2 shift.

2 security guards/ shifts.

12 worker for pouring the land.

1 electrician and 1 helper/ shift.


13/18

ESTIMATION & COSTING

Utilizing own apartment i.e. 500 family.

And rest power sold to another 500 family.(provision for

colony/Apartment).

For house utilization- 1.50 rupees/ unit.

POWER GENERATION

1 ton =150 to 250 kg of organic carbon

1000 ton=250000 kg of organic carbon

150 to 250 kg of organic carbon produces 1kw

250000 kg of organic carbon produces 1000kw
