Investigations on Biogas Recovery from Anaerobic Digestion of Raw Sludge and Its Mixture with Agri-Food Wastes: Application to the Largest Industrial Estate in Oman

Abstract: This work is intended to evaluate the technical, environmental, and economic feasibility of converting the sludge produced at an industrial estate’s wastewater treatment plant (WWTP) in Oman into energy through anaerobic digestion (AD). In this study, three different scenarios were analyzed. They concerned the digestion of the total amount of the produced sludge alone (240 m3 day−1) (scenario 1), and its co-digestion with wet agri-food wastes (AFW) at rates of two tonnes day−1 (scenario 2) and ten tonnes day−1… Show more

“…Jellali et al [17] assessed the environmental, technical and economic viability of the anaerobic digestion (AD) sludge formed in a wastewater treatment plant (WWTP). Based on the characterization of the sludge samples, it was mentioned that for a 20-year project the production of electricity through AD was 43.9 GWh, while at the same time the reduction of greenhouse gas (GHG) emissions was greater than 37,000 ton.…”

“…Processes 2022, 10, 231 2 of 19 Various studies investigated these wastes for targeted molecules extraction [6][7][8][9], biopolymers synthesis [10,11], fabrication of electrodes for energy storage systems such as batteries and supercapacitors [12,13] or highly porous media for air or water treatment [14][15][16]. Among the diverse valorization techniques of these agricultural wastes, the slow pyrolysis and hydrothermal carbonization received great attention for the synthesis of value-added and carbon rich materials, named biochars and hydrochars, respectively.…”

“…Among the diverse valorization techniques of these agricultural wastes, the slow pyrolysis and hydrothermal carbonization received great attention for the synthesis of value-added and carbon rich materials, named biochars and hydrochars, respectively. These generated byproducts have interesting characteristics that allow them to be valorized in numerous application fields [17][18][19][20].…”
