“…Other investigations tried to improve the hydrochars properties by increasing their specific surface area and porosities through chemical and/or physical activations. The resulting activated carbons were successfully applied for the removal of various pollutants from aqueous solutions (Xue et al, 2012;Zuo et al, 2016), air (Hao et al, 2016;Zhang et al, 2019) and soils (Chung et al, 2015;Kammann et al, 2012). Moreover, various researchers have increased the hydrochars specific surface area after thermal treatment at higher temperatures (Fang et al, 2016;Yu et al, 2019).…”

Hydrothermal carbonization (HTC) is considered as a promising technique for wastes conversion into carbon rich materials for various energetic, environmental and agricultural applications. In this work, the HTC of olive mill wastewater (OMWW) was investigated at different temperatures (180 -220°C) and both, the solid (i.e., hydrochars) and the final process liquid derived from the thermal conversion process were deeply analyzed. Results showed that the solid yield was affected by the temperature, i.e., decrease from 57% to 25% for temperatures of 180°C and 220°C, respectively. Furthermore, the hydrochars presented an increasing fixed carbon percentage with the increase of the carbonization temperature, suggesting that decarboxylation is the main reaction driving the HTC process. The decrease in the O/C ratio promoted an increase of the high heating value (HHV) by 32% for hydrochar prepared at 220°C. The process liquids were sampled and their organic contents were analyzed using GC-MS technique. Acids, alcohols, phenols and sugar derivatives were detected and their concentrations varied with carbonization temperatures. The assessment of the physico-chemical properties of the generated HTC by-products suggested the possible application of the hydrochars for energetic insights while the liquid fraction could be practical for in agricultural field.

In pursuit of establishing a circular economy, waste-to-energy approach is gaining increasing attention. In this manner valorization of sewage sludge constitutes a critical importance due to generation in high quantities, difficulties in disposal and associating environmental impacts. Hydrothermal carbonization (HTC) is a relatively recent, however acclaimed method for sewage sludge management and valorization due to process compliance with sludge characteristics. In this review, research studies are evaluated under the categorization of application fields of sludge derived HTC products such as solid fuel production, gas production, soil remediation, nutrient recovery, water treatment and energy storage. Research findings are compiled and a network mapping is employed for the visualization of the current situation and correlation in respective fields. The potential of HTC for sewage sludge valorization and future projections concerning available techniques are assessed within the context of circular economy.

In pursuit of establishing a circular economy, a waste-to-energy approach is gaining increasing attention. Valorization of sewage sludge constitutes a critical importance due to generation in high quantities, difficulties in disposal, and associating environmental impacts. Hydrothermal carbonization (HTC) is a relatively recent yet an acclaimed method for sewage sludge management and valorization due to process compliance with sludge characteristics. In this review, research studies are evaluated via categorization of application fields of sludge-derived HTC products such as solid fuel production, gas production, soil remediation, nutrient recovery, water treatment, and energy storage. Research findings are compiled and a network mapping is employed for the visualization of the current situation and correlation in respective fields.
