First, you should mention which type of waste you are asking for, solid, or liquid waste. Then you should have the analysis of this waste. Afterward, you can search about the possible alternatives. To convert waste to energy there are many processes, for example ( not all) , anaerobic digestion, pyrolysis, or gasification, then when you got your fuel, you can search about how to convert it to electricity. Thanks

Prof. Mahmoud, thanks for your answer. I'm looking for solid form especially for municipal solid waste. I read an article which says that the potential of electricity generation from energy of waste is around 82%. I want to ensure whether this is the maximum or any other higher figures available.

In our case, we converted the biogas (generated form restaurants  food waste) to electricity using solid oxide fuel cell with a conversion efficiency of 75%.

The amount of energy in municipal waste will be dependent on what's in the waste (as a previous reply stated) There is no standard as each municipality has different content very dependent on the city, the culture, the presorting of waste at the collection point, post collection sorting, etc. For example in Bangkok, the waste is presorted by the trash collectors to remove any items that are recyclable. Paper, plastic bottles, etc.

Terry, what is the electricity production capacity (%) from energy contained in municipal solid waste in Bangkok? 

Fazel, I am looking for municipal solid waste. In my country, food waste is the main constituent in MSW and its electricity production is similar with Prof. Mahmoud’s second answer. I know types of waste can be changed from country to country. I want to know figures of different regions and countries. Therefore, in your country, what is the electricity production capacity (%) from energy contained in municipal solid waste?

MSW needs segregation, it contains a wide range of wastes. IF biogas generation is intended then 0.06 cum of biogas can be generated through each kg of organic matter from the municipal solid wastes. The digested slurry can be sold as compost.

Thank you so much Fazel, very good answer to determine the connectivity between your regional conditions and electricity generation from MSW.

 Chinnusamy, what is the daily average organic waste quantity of MSW in Tamil Nadu?

In india it is 68.8 million tons per day. 1 cum of biogas produced from msw wastes generates upto 2 kwh of electricity. MSW In TN is around 3.5 to 4.2 MT each day. This is 2015 data.
