Hydrothermal carbonization (HTC) has emerged as a pivotal technology in the battle against climate change and fosters circular economies. Operating within unique reaction environment characterized by water solvent moderate temperatures at self-generated pressures, HTC efficiently converts biomass residues into valuable bio-based products. Despite HTC’s potential—from management of challenging wastes to synthesis advanced carbons implementation biorefineries—it encounters hurdles transitioning from academic exploration industrial implementation. Gaps persist, general comprehension intricacies difficulty large-scale integration with wastewater treatments, process water, absence standardized assessment techniques for Addressing these challenges demands collaboration bridge many scientific sectors touched HTC. Thus, this article reviews current state some hot topics considered crucial development: It emphasizes role cornerstone waste biorefineries, highlighting potentialities its development. In particular, it surveys fundamental research aspects, delving pathways, predictive models, analytical techniques, modifications while exploring technological applications challenges, peculiar focus on combined HTC, integration, plant energy efficiency.

Bioplastics possess the potential to foster a sustainable circular plastic economy, but their end-of-life is still challenging. To sustainably overcome this problem, work proposes hydrothermal carbonization (HTC) of residual bioplastics as an alternative green path. The focus on cellulose acetate - bioplastic used for eyewear, cigarette filters and other applications showing proof concept chemistry behind conversion, including reaction kinetics model. HTC pure commercial acetates was assessed under various operating conditions (180-250 °C 0-6 h), with analyses solid liquid products. Results show peculiar behavior these substrates HTC. At 190-210 °C, materials almost completely dissolve into phase, forming 5-hydroxymethylfurfural organic acids. Above 220 intermediates repolymerize carbon-rich microspheres (secondary char), achieving yields up 23 %, while itaconic citric acid form. A comparison additives demonstrates that amounts acetyl groups derivatives plasticizers are crucial in catalyzing reactions, creating unique environment capable leading total rearrangement acetates. can thus represent cornerstone establishing biorefinery acetate.
