Anaerobic digestion of nut and coffee wastes: different pretreatment techniques to enhance methane production
Oliva, Armando (NUI Galway, 2022-07-25)Lignocellulosic materials (LMs) are the most abundant residues on the planet and have a great potential for methane production. Nevertheless, the energy potential of LMs for biofuel production is limited by their complex ... -
Anaerobic digestion of selenium-rich wastewater for simultaneous methane and volatile fatty acid production and selenium bioremediation
Logan, Mohanakrishnan (NUI Galway, 2022-09-09)This research aimed at investigating the anaerobic digestion (AD) of selenium (Se)-rich and lipid-rich wastewaters via evaluating the operational parameters in sequential and continuous bioreactors. In the first part of ... -
Brewery spent grain cascade process: protein recovery and improved downstream fermentation for simultaneous volatile fatty acid production and recovery
Castilla-Archilla, Juan (NUI Galway, 2022-03-23)Volatile fatty acids (VFAs) are short chain carboxylic acids currently produced from fossil fuels. Renewable biomass, including organic wastes, could be used as an alternative source of VFAs. Brewery spent grain (BSG) was ... -
Evaluating the Environmental Efficiency of Bioplastics using Advanced Life Cycle Assessment
Bishop, George (NUI Galway, 2021-11-05)International bans on single-use petrochemical plastic products are accelerating the uptake of bioplastics to fill the gap in the market. Previous life cycle assessment (LCA) research exploring the environmental impacts ... -
Metal removal and recovery from zinc refinery residue using microbiologically produced elemental chalcogen nanoparticles
Saikia, Sudeshna (NUI Galway, 2022-09-20)This research aimed at investigating the application of elemental chalcogen nanoparticles for the removal of metals from wastewaters. In the first part of the study, biogenic (Bio) selenium nanoparticles (SeNPs) were ...
