Hydrochar (HC) has received increasing attention due to its potential impact on soil amendment. The process parameters of hydrothermal carbonization (HTC) have a significant the characterization HC, and HC as amendment effects properties. Therefore, this work summarizes feedstock type, temperature, residence time, solid–liquid ratio characteristics analyzes by addition. type determined HC. Temperature had greatest effect properties, while time similar but smaller than temperature had. did not affect when HTC was carried out certain extent. Solid–liquid research in area is lacking. Moisture crucial factor plant growth. Compared other soils, significantly increased water-holding capacity (WHC) sandy soils. rich nutrients micronutrients, making it potentially useful fertilizer. toxicity may inhibit growth be ignored for poor soil. This review aims provide recommendations identify areas where further needed.

Ecotoxicity Evaluation of Industrial Waste and Construction Materials: Comparison Between Leachates from Granular Steel Slags and Steel Slags-Containing Concrete Through a Plant-Based Approach

Bulletin of Environmental Contamination and Toxicology, Год журнала: 2023, Номер 111(1)

Опубликована: Июнь 21, 2023

Steel slags, the main waste product from steel industry, may have several reuse possibilities. Among others, building applications represent a crucial field. However, potential impact of harmful substances on environment should be assessed. The aim this study was to assess phytotoxicity slags (SS) and concrete mixtures cast with partial replacement SS (CSS). Leaching tests were carried out four CSS according EN 12457-2 UNI 15863, respectively. Each leachate assayed using root elongation 30 seeds Allium cepa, Cucumis sativus, Lepidium sativum, respectively, 12 bulbs A. cepa. latter also allowed analysis other macroscopic parameters toxicity (turgidity, consistency, colour change tip shape) evaluation mitotic index 20,000 cells per sample. None samples induced phytotoxic effects organisms tested: all supported seedlings emergence, verified by comparable to, or even greater than, that negative controls, did not affect cell division, as evidenced values. absence demonstrated leachates allows SS-derived considered reliable materials suitable for use in civil constructions engineering applications, economic environmental advantages, such reduction final disposal landfills well consumption natural resources.

Integrated valorization of digestate and concentrate from a centralized biogas plant via hydrothermal co-carbonization

Chemical Engineering Journal, Год журнала: 2024, Номер 496, С. 154061 - 154061

Опубликована: Июль 17, 2024

Centralized biogas production plants treating biowaste and/or sewage sludge generate high organic and nutrients containing waste streams (e.g., dewatered digestate reject water) for further valorization. However, evaporation of water results in ammonium-rich liquid recovery via stripping, leaving a concentrate without proper disposal or reuse. This study aims to recover energy from the concentrate, digestate, their mixture through hydrothermal carbonization (HTC). Specifically, HTC improved fuel properties by generating hydrochar with densification 1.26 % low ash oxygen contents. Filtrate demonstrated highest methane (250–261 mL CH4/g-COD). Nonetheless, after individual HTC, were mostly recovered while ended up aqueous fraction concentrate. In co-carbonization (co-HTC) mixture, distributed two fractions phosphorus most nitrogen nearly all potassium fraction. Despite attractive co-HTC rather than could be favorably considered as promising option large scale applications due its selectiveness towards well higher yield.

Hydrothermal carbonization (HTC) is beneficial for the disposal of high-moisture organic waste such as sludge. However, relationship between HTC parameters and hydrochars has not been fully explored, most studies have focused on single or dual parameters. This paper systematically studied how hydrothermal intensity solid loading affected process, hydrochar yield, composition properties. The results revealed that matter ash content in sludge was a vital factor affecting fuel properties hydrochars. critical process parameter hydrochars' structural had no apparent effect but considerable energy consumption process. When moisture 80.3%, recoverable by could be sufficient material to heated up phase transition. Evaluations characteristics different regions treatment processes were conducted, allowing optimized correlation with future resource utilization approaches.
