Summary: Organic fertilizer plays an important role in agricultural production. This study evaluated the potential of two agricultural and forestry wastes (corn cob and peanut residue) as organic fertilizers through hydrothermal carbonization (HTC). The study found that peanut residue was suitable for preparing organic fertilizers, while corn cob was not. Co-HTC of corn cob and peanut residue improved the nitrogen recovery rate. Evaluation of nutrient migration and transformation revealed the effects of thermodynamic conditions and raw materials composition.

Summary: Hydrothermal carbonization (HTC) is a promising strategy for converting wet biomass wastes into carbon-condensed solid hydrochars. Co-hydrothermal carbonization of cow manure with grape marc and corn stover did not enhance solid yield or higher heating value synergistically, but it did increase the electrical conductivity of hydrochars. Hydrochars have higher fixed carbon content and lower H/C and O/C atomic ratios than their parent feedstocks, reducing their susceptibility to thermal degradation and decreasing the bioavailability of heavy metals. The land application of hydrochars could potentially reduce phosphorous run-off and eutrophication compared to raw manure.

Summary: In this study, hydrothermal carbonization was used to reduce heavy metal concentrations in sunflower residues and improve the energy-related properties of the produced hydrochar. Optimal HTC temperatures for energy retention efficiency were found to be between 200 and 220 degrees Celsius. Hydrochar, with low nitrogen and ash content, can be considered a clean energy source for sustainable disposal and utilization of contaminant-containing biowastes.

Summary: This study found that hydrothermal carbonization treatment can improve the energy-related properties of cattle and pig slaughterhouse wastes, with more significant improvements observed in pig waste. Mild HTC treatment at around 200 degrees Celsius was deemed suitable for converting pig waste to value-added solid fuel. Energy recovery efficiency varies depending on the chemical composition of the raw feedstock.

Summary: This study assessed the chlorine mitigation and properties of solid products generated from waste polyvinyl chloride (WPVC) under high temperature cohydrothermal treatment (co-HTT). The results showed that the addition of 5% acidic hydrochar (AHC) increased the dechlorination efficiency (DE) of WPVC from 89.35% to 97.66% at 325 degrees C and 0.5 h. The highest DE of 99.46% was achieved at 350 degrees C and 1 h with 5 wt% AHC. Furthermore, loading 5% AHC improved the higher heat value (HHV) of the solid products from 23.09 to 31.25 MJ/kg at 325 degrees C and 0.5 h. The maximum HHV (34.77 MJ/kg) of a solid product was achieved at 350 degrees C, 4 h, with 5 wt% AHC. The co-HTT solids showed low slagging indices, fouling indices, alkali indices, and medium chlorine contents, supporting the viability of WPVC conversion into clean solid fuel via co-HTT.

Summary: Hydrothermal carbonization (HTC) is an effective and environmentally-friendly technology for value-added utilization of livestock wastes. Co-hydrothermal carbonization (co-HTC) of swine manure (SM) and corn cob (CC) was proposed to prepare organic fertilizers. The optimal co-HTC conditions were found to be 240°C, 120 min, and a mixing ratio of 1:1, leading to a co-hydrochar with a high total nutrient content, nitrogen recovery, and phosphorus recovery. Co-HTC treatment reduced phytotoxicity and improved seed germination. The hydrochars derived from co-HTC were rich in medium-microelements, which played a role in fixing phosphorus.

Summary: The study aims to utilize metal oxide-rich sewage sludge obtained from treated brewery wastewater to produce value-added solid fuel through co-hydrothermal carbonization process. The addition of coffee grounds and bagasse improves the fuel properties of the solid products and enhances their thermal stability and combustion reactivity. Co-hydrothermal process with biomass is a prospective approach to increase the value-added of sewage sludge feedstock as a solid fuel.

Summary: A treatment method for producing solid fuel from surgical face masks has been developed to address the cost and environmental concerns of medical waste management during the COVID-19 pandemic. The fuel properties of the solid fuel produced from face masks and from a mixture of face masks and biomass were investigated using a hydrothermal carbonization process and pyrolysis. The results showed that the fuel properties of the produced fuel were improved with an increased hydrothermal carbonization temperature. This research provides an environmentally friendly treatment method and potential utilization of polypropylene material as solid fuel.

Producing more bio-oil proves to improve the economics of the process, but factors such as capital costs and post-processing expenses should also be considered.
