Harnessing Activated Sludge for the Treatment of Hydrothermal Liquefaction Wastewater: A Proof‐of‐Concept Study

Water Environment Research, Volume 98, Issue 2, February 2026.
Activated sludge cultivation for sewage sludge HTL wastewater treatment was optimized using high temperature incubation, nutrient supplementation, high dilution factor, and overliming pretreatment. Up to 91.2% sCOD removal was achieved, with kinetics analysis confirming enhanced degradation rates under treatment optimization.

Solvothermal liquefaction of orange peels into biocrude: An experimental investigation of biocrude yield and energy compositional dependency on process variables

Bioresource Technology
The efficient valorization of biomass for energy-derived biocrudes is essential for effective waste management. However, the production of biocrudes with high energy and reduced oxygen contents during the liquefaction process requires further insight.

Ensiling and Fermentation of Rice Hulls With Ruminal Fluid for Medium‐Chain Carboxylate Production

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 1, January/February 2026.
ABSTRACT Large quantities of rice hulls are common at milling sites in Nigeria. They are a by‐product of rice processing and can contribute to environmental degradation if not properly managed. In this study, rice hulls were pretreated by ensiling at ambient temperature and then used as substrate for medium‐chain carboxylates (MCCs) production ...

Enhancing Deoxygenation of a Biopetroleum Model Compound Using Mesoporous Beta Zeolite

ChemCatChem, Volume 18, Issue 1, 15 January 2026.
Beta zeolite with 13 SAR is modified by alkaline and acidalkaline treatments to generate mesoporosity and improve accessibility of bulky molecules. Characterization confirms enhanced silicon removal and mesopore volume. In catalytic deoxygenation of a lignocellulosic‐derived model compound, treated BEA shows reduced oxygenates, higher hydrocarbon yield,
