Proposal for a Conceptual Biorefinery for the Conversion of Waste into Biocrude, H₂ and Electricity Based on Hydrothermal Co-Liquefaction and Bioelectrochemical Systems

Fermentation
Microalgal biomass contributes to the valorization of urban and agro-industrial solid waste via hydrothermal co-liquefaction (co-HTL) for the production of biocrude, a sustainable substitute for petroleum.

Cellulose Acetates in Hydrothermal Carbonization: A Green Pathway to Valorize Residual Bioplastics

ChemSusChem, Volume 18, Issue 2, January 14, 2025.
Pure and commercial cellulose acetates are subjected to hydrothermal carbonization as a possible end‐of‐life strategy. The plasticizers cause the material to completely dissolve in the liquid phase at 190 °C. Valuable carbonaceous solids and platform chemicals were observed in the products, proving the possibility of applying this approach in a ...

From Biomass to Biofuel: Innovative Microwave‐Assisted Rapid Hydrothermal Liquefaction of Palm Kernel Shells

International Journal of Chemical Engineering, Volume 2025, Issue 1, 2025.
The hydrothermal liquefaction (HTL) process turned out to be a very promising route for the production of bio‐oil from agricultural residue. However, limited number of researches have explored the production of bio‐oil from palm kernel shells (PKSs) using the HTL method.
