Abstract Hydrothermal carbonization (HTC) converts wet biomass into hydrochar and a process liquid, but aromatic compounds in the products have been reported as roadblock for soil applications they can inhibit germination, plant growth, microbial activity. Here, we compared HTC hydrothermal humification (HTH) of cow manure digestate while varying initial alkaline content by adding KOH. HTH converted 37.5 wt% feedstock to artificial humic acids (A-HAs) found both solid twice that HTC. reduced phenolic furanic over 70% solids 90% liquids. The A-HAs resemble natural (N-HA), based on FTIR, UV–vis spectra, CHN XRD analysis. liquid possesses 60% higher total organic carbon (TOC) than Although one-third TOC be precipitated A-HA, high concentration remains which is shown mainly acids. Therefore, also evaluated liquids anaerobic biomethane production, original digestate, increased methane yield 110.3 158.6%, significant enhancement relative 17.2% increase seen with liquid. strong reduction during biogas production from indicates potential converting soluble byproducts methane, maintaining levels product.

Abstract Limited information is available about potential physicochemical changes that can occur in hydrochar post-production, e.g. during drying and storage. Understanding these crucial not just for shaping future research plans, but also practical applications. Here we studied the effect of moisture (69.2% 2.4%) three storage temperatures (− 18, 4, 20 °C) over a year on selected organic inorganic compounds produced from Hydrothermal carbonization (HTC) digested cow manure. Comparison control wet hydrochars (WHs) dry (DHs) showed compound composition due to drying. Overall, total amount was notably greater WH (15.2 g kg −1 DM) compared DH (11.8 DM), with variations observed individual concentrations. Drying, however, had no significant influence identified compounds. Storage caused both DH, particularly after 12 weeks. Sugars (2–sevenfold), acids (36–371%), aromatics (58–120%) stored samples at week 52 were significantly higher than their values. Changes elements (e.g., Co, K, Mg, Mn, P, S, Sr, Zn) occurred faster WH, differences starting 1 values, while fewer changes. Based content, recommend optimal conditions HTC studies preserve properties. Finally, discussed applications hydrochars, showing stability, especially − 18 °C, making it suitable various Graphical

Effective treatment of plant biomass with potentially toxic elements (PTEs) is crucial for phytoremediation. Hydrothermal carbonization (HTC) offers an economical and eco-friendly solution by converting into high-value hydrochar. However, the effects reaction temperature medium on characteristics metals distribution in hydrochars from PTEs-containing remain unclear. This study explores different hydrothermal (180–240 °C) media (H2O, HCl, H2SO4, H3PO4) properties willow containing PTEs, transfer rules PTEs (Cd Zn) application potential The results indicated that acid significantly influenced WB conversion, affecting hydrochar such as degree surface functional groups. Higher temperatures enhanced Cd Zn fixation solid phase, while facilitated their migration to liquid phase. More than 91.08 % 88.41 acid-added system are migrated phase at 180 °C Hydrochar prepared under H3PO4 exhibited excellent adsorption performance Cd2+ Cu2+ (2.17 mg/g 34.38 mg/g, respectively) aqueous solution.
