Toward the Utilization of Char from the Hydrothermal Liquefaction of Polyethylene Plastic Waste: Studies of the Adsorption of Rhodamine B in an Aqueous Environment

Advanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Hydrothermal liquefaction of waste polyethylene produces char that effectively removes rhodamine B from water. Nearly complete dye adsorption is achieved under optimum conditions, with adsorption following Langmuir isotherm and pseudo‐first‐order kinetics.

Hydrothermal Liquefaction (HTL) of Lignin: The Adsorption Separation of Catechol Guaiacol and Phenol

Energies
The complex nature of the hydrothermal liquefaction (HTL) of lignin product downstream requires an effective separation strategy. In this study, the use of adsorption separation was undertaken using deep eutectic solvent (DES)-modified amberlite XAD-4 adsorbents to achieve this goal.

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...
