A review of wastewater sludge-to-energy generation focused on thermochemical technologies: An improved technological, economical and socio-environmental aspect

Cleaner Waste Systems, Journal Year: 2024, Volume and Issue: 7, P. 100130 - 100130

Published: Jan. 21, 2024

In response to increasing global waste generation due population growth, urbanization, and industrialization, wastewater treatment operations should shift from being solely energy consumers becoming producers by harnessing sludge (WWS). This approach holds great potential for meeting demands addressing the challenges of treatment. The recovery heat electrical WWS offers a viable solution reduce costs within WWTPs. Thermochemical technologies such as pyrolysis, gasification, combustion hold their efficiency, reaction times, retrieval capabilities. These demonstrate feasibility in terms operational costs, circular economy principles, socio-environmental impact, thanks ongoing advancements waste-to-energy research. review aims explore recovering bioenergy (biogas or syngas) generate energy, including heat, electricity, other innovative products. article provides critical comprehensive examination thermochemical technologies, taking into account technological, economic, factors. It then presents integration techniques that effectively combine anaerobic digestion with conversion enhance syngas, biogas, flue-gas energy. results this study underscore significant sludge-to-energy schemes.

Biochar development from thermal TGA studies of individual food waste vegetables and their blended systems

Biomass Conversion and Biorefinery, Journal Year: 2022, Volume and Issue: unknown

Published: Feb. 17, 2022

Abstract The amount of food waste that is generated all over the world enormous. As wastes are rich in nutrients and organics, they serve as a potential source for generation many value-added commodities energy. In most countries, predominately dumped open lands or incinerated, along with other combustible materials such municipal solid wastes, possible extraction However, these two modes disposal encountering more environmental, technical, economical challenges. More recently, it has been realized can be transformed into energy products, horticultural biochars, using thermochemical technologies pyrolysis gasification. current research work, three selected items, carrots, cucumbers, tomatoes, have studied thermogravimetric analysis. biochar analysis involves one single item (carrot), binary mixture (carrot + cucumber), ternary blend carrot, cucumber, tomato. Two heating rates were used order to perform kinetic modeling studies Arrhenius Coats-Redfern models. Since production gases—for chemicals production—is major economic significance regarding overall process viability, TGA syngas component, component tertiary systems analyzed by coupled mass spectrometry. results gas indicate an increase hydrogen due blending wastes.
