Abstract: The study is based on Lesvos island, Greece, which faces challenges in managing both agricultural biowaste and municipal sludge. The research focuses on using hydrothermal carbonization (HTC) to convert municipal sludge into hydrochar and hydrothermal liquor using a state-of-the-art reactor. The liquid by-product is processed through solar distillation, employing a solar still constructed at the University of the Aegean. The study also plans for the co-gasification of hydrochar with agricultural biomass, specifically olive tree pruning residues, using a biomass gasifier to be installed on the island. The methodological approach includes processing municipal sludge and waste activated sludge through hydrothermal carbonization at various conditions in a Parr hydrothermal reactor. The outputs, including hydrochar and liquid phase, were analyzed for energy content and chemical properties. The hydrochar showed a considerable heating value range from 19.27 to 23.87 MJ/kg, making it a viable candidate for biomass co-gasification. Results highlighted the integration of hydrothermal carbonization with solar distillation and co-gasification processes as an effective strategy for managing waste while generating energy. The study also examined the energy efficiency of the solar distillation process and the potential of syngas production from co-gasification, using thermodynamic modeling to predict the composition of syngas produced. This work contributes to the field by demonstrating a sustainable method for waste management that not only reduces waste but also harnesses it for energy production, aiding in the broader goals of sustainable and circular bioeconomy.

Abstract: The possibility of using microwave radiation to support the chemical thermohydrolysis of organic substrates has so far only been demonstrated on a laboratory scale. There is a lack of studies in large-scale plants that would provide the basis for a reliable evaluation of this technology. The aim of the research was to determine the effectiveness of using microwave radiation to support the acidic and alkaline thermohydrolysis of lignocellulosic biomass prior to anaerobic digestion on a semi-industrial scale. Regardless of the pretreatment options, similar concentrations of dissolved organic compounds were observed, ranging from 99.0±2.5 g/L to 115.0±3.0 in the case of COD and from 33.9±0.92 g/L to 38.2±1.41 g/L for TOC. However, these values were more than twice as high as the values determined for the substrate without pretreatment. The degree of solubilisation was similar and ranged between 20 and 28% for both monitored indicators. The highest effects of anaerobic digestion were observed with the combined process of 20 minutes of microwave heating and the addition of 0.10-0.20 gHCl/gTS as well as with alkaline thermohydrolysis. Between 99 and 102 LCH4/kgFM were achieved with these variants. For the control sample, the value was only 78 LCH4/kgFM and for the other variants it was between 79 and 94 LCH4/kgFM. The highest net energy gain of 3.51 kWh was achieved in the combined alkaline thermohydrolysis with NaOH doses between 0.10 and 0.20 g/gTS.
