Medium-scale farms using anaerobic digestion must choose among different biogas utilization pathways, each with distinct technical and environmental implications. This study develops an integrated assessment framework that combines Aspen Plus process simulations with life cycle assessment in openLCA …

Lignocellulose represents an abundant repository of renewable carbon. Derived from various plant sources, it holds tremendous potential as a renewable and sustainable feedstock for the production of valuable chemicals and fuels. However, its solid fermentable compounds, cellulose and hemicellulose, are …

To broaden the application of biomethanation for energy storage and renewable integration, this study investigates the performance of a trickle-bed reactor (TBR) for hydrogen (H2) utilisation in biogas upgrading, using both pure Carbon dioxide (CO2) and biogas-derived CO2 as substrates for methane (CH4) …

Power-to-X technologies play a crucial role in accelerating the energy and material transition. A key opportunity lies in integrating these systems with existing bio-based infrastructures such as anaerobic digesters, providing a reliable source of biogenic carbon. Developing effective Power-to-Methanol …

Thesis which explores a Wingate variation that we developed together to better simulate athletes’ sport conditions characterised by repeated short bouts of high-intensity effort. The aim of this thesis was to investigate the interrelationship between Body Mass Index (BMI) and anaerobic performance using …

Polyhydroxyalkanoate (PHA) is a biodegradable bioplastic that can be produced by bacteria when consuming a carbon source. Volatile fatty acids (VFAs) are used as building blocks for PHA bioplastics and can be efficiently produced from organic waste through anaerobic digestion. However, the variable composition …

Biogas production involves the complex process of anaerobic digestion in bioreactors. This paper presents numerical modeling results and analysis of bioreactors. We discuss research methodology, model geometry, internal bioreactor processes, and possible modifications. Two mathematical models and their …

Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative …
