Nowadays the sludge treatment is recognized as a priority challenge to wastewater industry due increasing volumes produced and tighter environmental controls for its safe disposal. The most cost-effective process sewage anaerobic digestion but raw digestate still contains high levels of organic matter that can be transformed into an energy carrier by using processes like Hydrothermal Carbonization (HTC). In this work, influence solid loading (2.5, 5.0, 10.0, 15.0, 17.5, 20.0, 25.0 30.0%...
Anaerobic digestion is an efficient way of using a wet fraction municipal solid waste (MSW) for energy purposes as it can produce biogas. The moisture content the digestate after application mechanical dewatering still high, and amount heat needed drying significant. Hydrothermal carbonization (HTC) process that potentially offer great benefits by improved valorization into better quality fuel. This study focuses on determination optimum HTC conditions to recover water from MSW digestate....
A novel process to produce a H2-rich syngas from high moisture-containing agricultural waste digestate is proposed. This combines the use of hydrothermal carbonization (HTC), dewatering, pyrolysis, and catalytic reforming. Due feature moisture content in digestate, effect HTC dewatering on performance interest, four scenarios were considered. Furthermore, three pyrolytic temperatures chosen understand pyrolysis conditions produced syngas. life cycle assessment was conducted investigate...
Abstract Feedstock properties play a crucial role in thermal conversion processes, where understanding the influence of these on treatment performance is essential for optimizing both feedstock selection and overall process. In this study, series van Krevelen diagrams were generated to illustrate impact H/C O/C ratios products obtained from six commonly used techniques: torrefaction, hydrothermal carbonization, liquefaction, gasification, pyrolysis, gasification. Machine learning methods...
Abstract Different strategies for sewage sludge management have been implemented to minimize the environmental impacts and benefit from resources embedded in this waste stream. In that regard, Hydrothermal treatments (HTTs) of biomass can contribute generating high-value products (hydrochar) enhancing biogas generation. work, different were analysed implementing HTTs at WWTPs considering effect 2 process temperatures (160 250 °C) on samples (primary, secondary digestate sludge)....
Digestate is a nutrient-rich substance produced by anaerobic digestion that contains organic, inorganic, and biological matter. The European Nitrates Directive (91/676/EEC) provides regulations regarding the wider implementation of digestate. Owing to significant amount organic matter in digestate, it can be utilised as solid biofuel, soil amendment substance, or substrate for activated carbon production. However, by-products municipal waste wet fraction cannot used such applications because...
Fast pyrolysis has been a subject of intensive research thanks to its ability produce high yields liquid products, known as oil. This is an important renewable intermediate which could be used for the subsequent production fuels and chemicals. For fossil-based materials, oil can provide circular building blocks. Furthermore, direct use in gas turbines also proven feasible. However, relatively oxygen content raw biomass detrimental effects on quality such work proposes hydrothermal...
Organic fraction of municipal solid waste is a type biomass that attractive due to its marginal cost and suitability for biogas production. The residual product organic digestion digestate, the high moisture content which problem, even after mechanical dewatering, significant heat requirement drying. Hydrothermal carbonisation process can potentially offer great benefits by improved dewatering valorisation digestate into better-quality fuel. However, such produces liquid by-product effluent...
One of the processes that can serve to valorise low-quality biomass and organic waste is hydrothermal carbonization (HTC). It a thermochemical process transpires in presence water uses heat convert wet feedstocks into hydrochar (the solid product carbonization). In present experimental study, an improvement consisting increased hydrophobic character HTC-treated demonstrated through presentation enhanced mechanical dewatering at different pressures due HTC valorisation. As part this work’s...
New regulations aimed at curbing the problem of eutrophication introduce limitations for traditional ways to use by-product anaerobic digestion—the digestate. Hydrothermal carbonisation (HTC) can be a viable way valorise digestate in an energy-efficient manner and same time maximise synergy terms recovery water, nutrients, followed by more efficient remaining carbon. Additionally, hydrothermal treatment is feasible recirculate recalcitrant process residues. Recirculation digestion enables...
