Waste To Energy (WTE) is Process / Technology to obtain useful energy from waste (MSW / RDF), in the form of Heat (or) Electricity (or) Fuel for further conversion.
There are various Process / Technology available in WTE
Biological Processing Technology (Composting, aerobic digestion, Bio-methanization, etc)

16. WTE - INCINERATION
Incineration Technology is a well developed technology followed in many countries from past few decades. In India also recently, few plant are in continuous operation with this technology.
Incineration is the Engineered process of controlled burning / combustion of solid waste at a high temperature, in the presence of oxygen.
Incineration of Municipal Solid Waste (MSW / RDF) is divided in to two broad categories
Burning “as received” waste.
Burning “pretreated” waste.
Burning of the “as received” waste requires little or no pretreatment (RDF – 1 & 2). This is termed as Direct Mass Incineration (DMI). Burning of pretreated waste (RDF – 3, 4 & 5), requires considerable amount of treatment process.

18. INCINERATION - ADVANTAGES
It address two sets of environmental issues in one stroke – Land use and pollution issues & Environmental impacts of fossil power plants
Volume and weight reduction (approx. 85 to 90% in volume and 75% in weight)
Waste Reduction & Destruction is immediate, no long term wait is required
No foul smell and infections to the public
Incineration is carried out at generation site
Air discharges can be well controlled to the permissible norms
Ash residue is usually do not protrude, they are sterile & inert
Small disposal area required
Investment cost can be offset by heat recovery / sale of energy

Pretreatment of MSW is not required
High capacity and thermal efficiency
Drying and carbonization takes place in the first zone, followed by ignition and combustion in the second and complete burn-out and cooling of the slag in the third.
RDF, Sludge, co-firing , etc
Requires extensive pre-treatment of MSW
Waste is introduced into a sand bed which is fluidized via blowing air through a nozzle floor
Very sensitive towards the RDF size and its density
For Hazardous and hospital waste.
Cannot be used for burning MSW.
Burning at a very high temperature with a long residence time and requires support fuel.

47. SUMMARY (MSW - A new beginning for an old source)
DMI with Energy Recovery is one of the best WTE technology suitable for wide varying fuel like MSW, for effective disposal of waste. There are more than 1000 WTE plant with DMI technology in operation world wide. In India, around four (4) plants are is successful operation and few plant are under construction stage.
In the incineration technology, there is a volume reduction to an extent of 90% and the gasses are let out from the chimney, satisfying the pollution norms. Most of the ash from the WTE plant can used.
There is a power generation potential from the MSW in the order of 270 to 445kW / TPH of MSW depending on the LCV.
With Tipping Fees, Capital Subsidiary from the Government & Export power cost above 7.0Rs / unit, the DMI based WTE project becomes viable with a pay back less than 5.0years.
