“…55 Pyrolysis is the process of thermal decomposition of materials in the absence of oxygen and converting the waste to a mixture of solid, liquid and gaseous products. 60,61 The mean energy content in the pyrolysis products is significant, thus energy recovery is high. 62 Torrefaction is a method for the conversion of biomass and various other combustible materials in MSW and increasing the energy density of MSW.…”

Municipal solid waste (MSW) consists of the waste obtained from various sources like households, industries, municipalities and other commercial areas. Common landfill and incineration strategies are insufficient to process the waste generated on daily basis. Municipal solid waste contains significant amounts of organic carbon (50–60%) that has great potential for the production of fuels and value‐added products. This review discusses the composition of the organic fraction of municipal solid waste (OFMSW) and waste processing strategies that enable organic carbon recovery compared with conventional methods. Changes in the composition of MSW worldwide and the factors influencing it in various regions are discussed in this study. The processing of diverse OFMSW through thermochemical methods such as incineration, gasification, pyrolysis, torrefaction and hydrothermal carbonization is discussed here with the results of densification or gasification of the organic carbon, enabling its chemical transformation. Additionally, the combined methods, where OFMSW is pre‐treated followed by enzymatic hydrolysis for the conversion of OFMSW to monomeric sugars have also been described. Globally, to ensure sustainable solid waste management and efficient carbon recycling, combined methodologies seem more appropriate. The study also attempts to list the different attempts across the globe that highlight this concept of the transformation of waste into materials and chemicals, improving its commercial value. The commercial success of such OFMSW processing attempts can provide momentum for establishing sustainable treatment technologies and reaping profits, laying the groundwork for a strong and complete carbon‐recycling environment and circular carbon‐based economy. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd

“…The technology for garbage pyrolysis is very mature, which is more representative of the Siemens Schwel–Brenn technology, the United States MTCI company waste gasification process and the Thermoselect company’s Thermoselect technology. 46 In the 1990s, Siemens developed the Schwel–Brenn pyrolysis gasification process. The MTCI developed a steam reforming technique in a bubbling fluidized bed reactor with a number of Helmholtz type resonant tube pulsed burners that provide the required gasification process by burning a portion of the syngas produced by the gasification of the waste energy.…”

Renewable energy accounts for 33 percent of the primary energy consumption across the world. Current world faces a major waste and climate change crisis. In many developing countries, over the past two and a half centuries, a variety of renewable power techniques have been actively pursued in distinct fields in the fields of research, growth, demonstration, manufacturing, and implementation. A replacement for fossil fuels using waste biomass is essential and considered as a promising strategy to meet our energy needs. At the same time, the emissions of greenhouse gas and managing municipal solid waste have to become crucial due to growing population demand. Biomass includes the energy stored in the sun and plants. It also serves as a primary energy source. Plants absorb the power of the sun during the process called photosynthesis. When biomass is combusted, chemical energy can be released into biomass as heat that can be used for domestic applications. The use of biomass results in management expenses contributes to climate changes, decrease the risk to lives and assets thereby ensure a safe and competitive energy source for the beneficial impact on the environment and the economy. This paper overviews about various applications of renewable energy sources produced from the municipal wastes and microbes. Prospects for the commercialization of bio-algal fuels, applications, and its challenges are discussed. The role of microbes (microalgae) in the energy production process and to use bioenergy as a future trend for economic development is discussed.

“…However, even the last generation of waste incinerators are limited by low electric efficiency of about 22-25% [18] because of the maximum steam temperature at the boiler outlet, which is normally lower than 450 • C to prevent corrosion by gaseous HCl [19,20]. Moreover, the incineration process generates a lot of acid gases, heavy metals, dioxins, and other pollutants [21]. For these reasons, in recent years, a considerable interest has grown toward other WtE technologies, particularly pyrolysis and gasification [21].…”

This paper addresses the study of a pyro-gasification plant designed, built, and operated to recover inert metals from different types of solid waste. Experimental tests were carried out using pulper as the solid waste. However, while a reliable composition analysis of the produced syngas was carried out, a precise composition evaluation of the pulper used during the experimental activities was not performed and the related data were characterized by unacceptable uncertainty. Therefore, with the aim of reliably characterizing the plant operation, a thermochemical model of the gasification process was setup to simulate the equilibrium operation of the plant and a vector optimization methodology was used to calibrate the numerical model. Then, a decision-making problem was solved to identify the most suitable optimal solution between those belonging to the Pareto optimal front, thus obtaining reliable composition data for the adopted pulper waste. In particular, four different identification criteria were applied for the selection of small subset of solutions over the 3138 dominant solutions found. Among them, the solution (i.e., set of calibration parameters) that minimizes the experimental-numerical difference between the lower heating value of the produced syngas seemed to provide the most reliable approximation of the real plant operation. Finally, a possible plant configuration is proposed for the energetic valorization of the pulper waste and its overall conversion process efficiency is estimated.
