Waste to Energy and Syngas

Abstract

Getting energy from waste is one of the best alternatives for sustainable handling of waste. Mass burning is generally the preferred option. Usually, this applies to large facilities where more than 500 tons of waste per day are treated. Syngas production from waste has also been tried with mixed success. This chapter reviews the situation in this field and proposes an alternative based on co-combustion with coal as a possible route, applied preferably to treat municipal solid waste (MSW) and biosolids from small-or medium-sized municipalities, producing less than 200 tons of waste per day, with the aim of generating electric energy. For this, a theoretical model is proposed and applied to a specific case.

Thermal destruction of polymers: analysis of the process physicochemical parameters

“…The importance of the study of the compositions of synthesis gases obtained from waste and the impact on their composition exerted by the parameters of the gasification chambers, working conditions, and temperature levels is shown in work [9].…”

Genetic Engineering of Oligotropha carboxidovorans Strain OM5—A Promising Candidate for the Aerobic Utilization of Synthesis Gas

“…, from steel manufacture or from oil refining), of gasified lignocellulosic biomass from agriculture or forestry, or even of gasified industrial, municipal, and domestic waste as a substrate for microbial production systems in value-added chains. A typical gas mixture from these sources contains carbon monoxide (CO), hydrogen (H 2 ), and carbon dioxide (CO 2 ) as main compounds, also often called synthesis gas or syngas. − The Fischer–Tropsch process is a well-established technique for the conversion of coal syngas in industrial scales; however, due to impurities and to changing compositions of biomass or municipal solid waste, the process is not well suited for syngas from these sources. In comparison, biological systems offer advantages to such chemical processes, e.g.…”
