Evaluation of food waste energy content through bio-fuels production

Comparing the effects of Al-based coagulants in waste activated sludge anaerobic digestion: Methane yield, kinetics and sludge implications

“…The process of anaerobic digestion consists of various sequential steps: solubilization of particulate organic matter, hydrolysis of organic macromolecules (e.g., proteins, carbohydrates) into monomers, acidogenesis of organic micromolecules (e.g., amino acids), acetogenesis of acid fermentation products and methanogenesis of hydrogen and acetates [ 39 ].…”

Energy recovery from bio-fuel production through two-stage anaerobic co-digestion process

“…This study is a development of the research of Baldi et al [12], where one-stage and two-stage AD processes were performed for different feedstocks with the aim of evaluating the performance of the process in terms of biofuel production. Previous studies [1], [20], [24] have compared similar scenarios for the assessment of energy recovery of gas flows obtained through the one-stage and two-stage AD processes. The objective of this work is to compare the energy performances related to Primary Energy Saving of different biogas users for different AD scenarios.…”

“…Data were collected from different sources: methane and hydrogen production data were obtained by carrying out semi-continuous tests in one and two-stage systems [12], while other data were provided directly from the WWTP management data considered as a case study [1], [24].…”
