Intensive agriculture relies heavily on synthetic fertilizers, causing resource depletion and environmental issues such as nutrient leaching. Biogas liquid digestate offers a nutrient-rich byproduct from anaerobic digestors as a circular alternative source for plant nutrients in closed-loop. Within …

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 …

Introduction Reduced aerobic capacity and frailty are highly prevalent in liver transplant candidates and are associated with increased morbidity and mortality. Although exercise-based prehabilitation is safe and effective, adherence remains a challenge. Home-based prehabilitation may improve participation, …

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 …

Managing dairy excreta as slurry can result in significant emissions of ammonia (NH3) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions …

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 …

Source Segregation (SS) is a novel strategy in dairy housing that can reduce emissions and separate organic matter and nutrients more efficiently than traditional slurry solid-liquid separation. The anaerobic digestion (AD) methane yield of the SS fractions, however, is unknown. We aimed at unveiling …
