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 …

This study investigates the integration of biochar production with CCS as a hybrid biomass-based CDR pathway that could enhance net carbon sequestration while reducing pyrolysis-related CO2 emissions. Biochar and BECCS are often treated as separate options, even though they rely on similar biomass supply …

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 …

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 …

This work presents an experimental holistic approach for the design of a continuous catalytic conversion process of carbohydrates derived from waste biomass to 5-hydroxymethylfurfural (5-HMF) using a tin-doped active carbon catalyst. In this report, apple biomass waste is used as a model component as …

Pyrolysis liquids from lignocellulosic biomass have the potential to be used as a feed for aromatics such as benzene, toluene, and xylenes (BTX) using catalytic upgrading with zeolites. We here report an experimental study on the conversion of various pyrolysis oil fractions to determine the most suitable …

De downstreamverwerking van PHA’s is vaak energie-intensief, oplosmiddelrijk en milieutechnisch onduurzaam. Om de algehele haalbaarheid van het proces te verbeteren, is er toenemende belangstelling voor alternatieve valorisatiestrategieën die conventionele extractiestappen omzeilen. Deze studie onderzoekt …

De downstream processing van polyhydroxyalkanoaten (PHA’s) is vaak energie-intensief, solvent-intensief en milieutechnisch niet duurzaam. Om de algehele proceshaalbaarheid te verbeteren, is er toenemende belangstelling voor alternatieve valorisatiestrategieën die conventionele polymeerextractie omzeilen. …

"What sparks student motivation in their very first semester? At our university, all Energy and Environmental Engineering 1st year students design, build, and test a biomass cookstove. This playful challenge stimulates belonging, builds teamwork, and gives students a first taste of the competences they …

This paper evaluates the potential impacts of introducing low-carbon intensity hydrogen technologies in two oil refineries with different complexity levels, emphasizing the role of hydrogen production in reducing CO2 emissions. The novelty of this work lies in three key aspects: Comprehensive system …
