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...
Hydrothermal carbonization (HTC) is a proven cost-effective and energy-efficient method for waste management value-added product recovery. There are, however, several issues that require further improvement or research. Identifying the strengths weaknesses of HTC in comparison to traditional pyrolysis crucial scientists choose between them use both (complementary) achieve specific properties. Additionally, sharing information on diverse modeling approaches scales enhance robustness...
The increasing reliance on commercial inorganic fertilizers has raised significant environmental and economic concerns, including soil degradation, nutrient leaching, water pollution, greenhouse gas emissions. This review critically evaluates biomass-derived chars produced via thermochemical processes, i.e., pyrolysis, gasification, hydrothermal carbonization, as potential alternatives to synthetic fertilizers. Among the three chars, biochar stands out most viable option for amendment due...
Abstract Metal uptake and removal from the soil by plants may be a useful measure to remediate contaminated soils. These processes can enhanced adding metal chelators soil. We investigated effect of nitrilotriacetate (NTA) urea on Cd, Cu, Zn lettuce ( Lactuca sativa L. cv. Orion) Italian ryegrass Lolium perenne Bastion) in pot experiments. Nitric acid‐extractable heavy concentrations were 2 mg 530 700 kg −1 . Three NTA treatments (0.5, 1.8, 5.3 mol m −2 ) compared with two (0.25 0.9 ),...
Dye tracer experiments have often been used to study the prevailing flow regime, such as in investigating role and extent of preferential water. Flow patterns two‐dimensional profiles provide qualitative information on infiltration regime but are difficult analyze compare quantitatively. The scope this was develop a quantitative method spatial distribution stained areas vertical profiles, identify differing transport mechanisms basis pattern information, how discriminated correspond with...
Multiphase flow processes in fractured rocks are of major importance for the remediation subsurface contamination, engineering petroleum reservoirs, and safety analysis nuclear waste repositories. We developed procedures determining water retention curve, gas permeability function, pore structure undisturbed fracture‐zone samples with cohesionless fault gouge layers laboratory. Mylonitic were taken at Grimsel Test Site (Switzerland). Intrinsic permeabilities 5 orders magnitude higher,...
In recent years, promising developments in the hydrothermal carbonization (HTC) of sewage sludge, as well potential to reclaim phosphorus and nitrogen, have emerged. this study, HTC digested sludge (DSS) was investigated for downstream production heavy metal (HM)-free fertilizer use freeze concentration (FC) a novel technology process water treatment. To obtain clean fertilizer, phosphatic acid extracts were first treated with ion-exchange resins remove dissolved HM, precipitating agents...
