About this Research Topic
Hydrothermal Liquefaction (HTL) represents a promising pathway for bio-crude oil production from a high variety of wastes (i.e., sludge, food waste, certain plastic material, etc.). During the process, a complex aqueous by-product phase is produced containing valuable chemicals, but which also poses significant disposal challenges. The treatment of this aqueous phase, the recovery of valuable products, and understanding the downstream implications are crucial for the sustainable deployment of HTL. This article collection focuses on these critical areas, aiming to provide insights and solutions to optimize process efficiency, reduce waste, and enhance product value.
The goal of this collection is to highlight the latest research, technologies, and methodologies that address the complexities of the aqueous phase. By exploring strategies to recover valuable compounds and minimize environmental impact, this edition aspires to promote sustainable practices in HTL.
This Research Topic will bring together diverse voices and perspectives in the field of HTL aqueous phase treatment. We will invite authors from industrial perspectives, including those exploring HTL at Water Resource Recovery Facilities (WRRF) such as the Great Lakes Water Authority, and those involved in building demonstration projects like Metro Vancouver, Arbios, Steeper, and Licella. International authors from academic institutions and national laboratory settings advancing the front lines of research on aqueous phase treatment will be invited to contribute their cutting-edge findings. Furthermore, experts will be solicited to discuss the economic and greenhouse gas implications of various technologies. This unique blend of contributors ensures a comprehensive examination of the subject, bridging practical applications, innovative research, and broader societal implications.
We welcome the submission of Original Research, Review, Mini-Review and Perspective articles on themes that include, but are not limited to:
• Anaerobic digestion of HTL aqueous phase
• Impact of HTL aqueous phase in upstream/downstream processes
• Separation of valuable chemicals from HTL aqueous phase
• Treatment of HTL aqueous phase with bio-electrochemical systems
• Treatment of HTL aqueous phase with gasification
• Treatment of HTL aqueous phase with super critical water oxidation
• Life cycle and/or techno-economic analysis of HTL aqueous phase treatment
