There are books dealing solely with waste to energy conversion. This is a summary of what is going on & what is hoped for in the near future:

Waste to energy (WET) conversion has not reached the high potential of Advanced Thermal Conversion Technology (ATCT) as claimed by some. This technology involves pyrolysis which thermally degrades biomass & organic solid wastes in the absence of oxygen to give synthesis gas or syngas "which is a good source of energy". The gasification process & the resulting gas could be used for the production of electricity, steam, hot water, and biofuels. The by-products, the majority of which is biochar, which is a nitrogen rich organic fertilizer.

Alternatively, the solid organic wastes (if isolated from other wastes) may be subjected to fermentation which could yield methane "the major component of natural gas" which is one of the best fuels. If research succeeds in converting cellulose into ethanol efficiently, then all the waste papers, cartoons, tree leaves, and plants wastes could be used for obtaining a good source of energy.

Biogas, Biofertilizers & Biopesticides, Composting, Electricity from Municipal solid waste, utilization of industrial wastes in cement-concrete systems and more.

All these processes reduces the release of green house gases in various manner. These processes convert solid waste into energy either by protecting the degradation of soil from chemical fertilizers and pesticides, conversion of agricultural or kitchen waste or animal dung into biogas (energy), composting for organic fertilizer production, reduction of CO2 emissions from cement plants when uses industrial wastes as cementitious materials etc. 

Perhaps this information could helo you to find the full answer to your question. The different biomass types can be divided into four categories:

• Forest biomass and forestry residues;

• Energy crops;

• Agricultural residues; and

• Organic waste.

Forest biomass

In the context of bio-energy, forest biomass includes several types of raw woody materials derived from forests or from processing of timber that can be used for energy generation:

• Stem-wood: Biomass from pre-commercial and commercial thinning and final felling, available for energy production, including whole trees and delimbed stem-wood from pre-commercial thinning;

• Primary forestry residues: Logging residues and stumps;

• Secondary forestry residues: Wood processing industry by-products and residues, like sawdust and cutter chips, bark, slabs, lump wood residues, and black liquor;

• Woody biomass from short rotation plantations on forest lands; and

• Trees outside of forests such as trees in settlement areas, along roads and on other infrastructural areas.

Energy crops

Five main types of energy crops can be distinguished, and are further classified as annual (a) and perennial (p) crops:

• Oil containing crops: Like sunflower (a), rape (a), soy (a), oil palm (p), and jatropha (p);

• Sugar crops: Like sugar cane (p), sugar beet (a), and sweet sorghum (a);

• Starch crops: Like corn (a), wheat (a), barley (a), and cassava (a);

• Woody crops: Like poplar (p), and eucalyptus (p); and

• Grassy crops: Like miscanthus (p), and switch-grass (p);

Agricultural residues

Agricultural residues are the by-products of agricultural practice. A distinction is made between primary or harvest residues (like straw) that are produced in the fields and secondary residues from the processing of the harvested product (like bagasse, rice husks) that is produced at a processing facility. Manure is included as a separate category. By-products from further processing of agricultural products like molasses, vinasse, etc., are regarded as residues from the food industry and are not included in this group.

Organic waste

Organic waste includes biodegradable waste from households, industry and trade activities. Organic waste includes biodegradable municipal waste, construction and demolition wood, and sewage sludge. Bio-gases from sewage treatment plants as well as landfill gas are also included as energy carriers from organic wast.

Bio-energy can be produced from a variety of biomass feed-stocks. Through a variety of processes, these feed-stocks can be directly used to produce electricity or heat or can be used to create gaseous, liquid, or solid fuels.

The range of bio-energy technologies is broad and the technical maturity varies substantially. Some examples of commercially available technologies include small-and large-scale boilers, domestic pellet-based heating systems, and ethanol production from sugar and starch. Advanced biomass integrated gasification combined-cycle power plants and lignocellulose-based transport fuels are examples of technologies that are at a pre-commercial stage, while liquid bio-fuel production from algae and some other biological conversion approaches are at the research and development phase. Bio-energy technologies have applications in centralized and decentralized settings, with the traditional use of biomass in developing countries being the most widespread current application. Bio-energy typically offers constant or controllable output. Bio-energy projects usually depend on local and regional fuel supply availability, but recent developments show that solid biomass and liquid bio-fuels are increasingly traded internationally: Due to feed-stock availability issues, dedicated biomass plants for combined heat and power, are typically of smaller size and lower electrical efficiency compared to coal power plants (30-34% using dry biomass, and around 22% for municipal solid waste). In co-generation mode the total efficiency may reach 85-90%. Biomass integrated gasification in gas-turbine plants is not yet commercial, but integrated gasification combined cycles using black-liquor (a by-product from the pulp and paper industry) are already in use. Anaerobic digestion to produce bio-gas is expanding in small, off-grid applications. Bio-refineries may open the door to combined, cost-effective production of bio-chemicals, electricity and bio-fuels.

Waste is considered by many as wealth/a resource itself, once it is segeragated, re-used or recycled and as such an income-generation for many many jobless/cottage industry, specially in developing countries.Waste to energy should not be a priority approach/option and if at all applied may be only to the "Left Over" waste, after all possible re-use/recycling. There are a number of strongly advocated proposed waste-to-energy technologies but none of these could claim zero emission/releases of hazardous gases and ash. These technologies also require a contineous availability of a standard quantum of wastes, to function on full capacity and full time which almost amount to promotion of waste generation. Should we at all go for "Waste to Energy" or rather opt for promotion and introduction of alternate technologies to meet our fast growing energy needs.

Dear Saumendra Aggarwal,

I hope you are doing fine.

My research team is extensively working on this topic of waste to energy, waste biorefinery, pyrolysis and anaerobic digestion and published several article in recent years on this topic.

Please see the following related publications of my research group at the following web-link
