Abdeldayem, O.M.H.M. (author), Dupont, Capucine (author), Ferras, David (author), Ndiaye, Lat Grand (author), Kennedy, M.D. (author)Although industrial hydrothermal carbonization (HTC) uses wet feedstock, lab-scale studies tend to dry the feedstock under the assumption that the rehydration of the feedstock would restore its original properties. To the best of our knowledge, this assumption has not been thoroughly examined at the lab scale; therefore, its investigation is...journal article 2024

Milisav, Andrej (author)The transport sector remains one of the largest CO2 emitting sectors globally. Decarbonizing the transport sector is an important aspect in the energy transition. The word transition is key, since it will take several decades or more to transition to a fully sustainable world. During this transition mainly heavy-duty vehicles and probably most...master thesis 2023

Bias, Nikos (author)The global temperature rise has pushed governments more into finding ways to reduce CO2 emissions, by increasing the use of renewable fuels. Lignocellulosic biomass (wood, forest residues, agricultural residues) is a renewable fuel that has still not been utilized to its full potential. That is because it lacks properties such as homogeneity,...master thesis 2023

Li, Ji (author), Hao, Xiaodi (author), Shen, Zhan (author), Wu, Yuanyuan (author), van Loosdrecht, Mark C.M. (author)A high moisture content of waste activated sludge (WAS) associated with a low calorific value needs to be deeply dried towards self-supporting incineration. On the other hand, thermal energy with low temperature exchanged from treated effluent has great potential for drying sludge. Unfortunately, low-temperature drying of sludge seems to be...journal article 2023

Jankovic, T.J. (author), Straathof, Adrie J.J. (author), Kiss, A.A. (author)Lignocellulosic biomass potentially represents a great feedstock for biofuel production, but its’ pretreatment needs to be enhanced in order to make biorefineries competitive with fossil fuel based alternatives. One way to make biorefineries more economically viable is to recover and valorize all generated by-products during the biomass...book chapter 2023

Cutz, L. (author), Maldonado de León, H.A. (author), Zambrano, Gamaliel (author), Al-Naji, Majd (author), de Jong, W. (author)The oil palm industry has been under public scrutiny during the last decades due to environmental and social issues related to its practices. Oil palm (Elaeis guineensis Jacq.) trunks (OPTs) are of special interest as they are left idle in the field after the replanting process which is performed every 25 years. This common practice results...journal article 2023
