Hydrothermal carbonization (HTC) solid and liquid products may inhibit seed germination, necessitating post-treatment. The hydrothermal humification (HTH) method addresses this drawback by transforming inhibitory compounds, such as aromatics, into artificial humic acids (AHAs) fulvic (AFAs). This study introduces a novel approach investigating the substitution of commonly used alkaline agent in HTH, KOH, with hydrated lime to develop cost-effective fertilizers from sugar beet pulp, enriching them AHAs. It assesses effects on AHA production soluble organic compounds compared KOH. results indicate that significantly reduces furans (from 560 3.15 mg/kg DM 344 3.86 mg/L process liquid) boosts sugars acids, especially lactic acid 4.70 65.82 g/kg 4.05 22.89 liquid), increasing hydrochar yield (68.8% vs. 27.4% KOH). Despite lower KOH (3.47% 15.50%), lime-treated are abundant calcium magnesium, boasting pH 7. property presents safer more efficient alternative fertilizers. characterization AHAs aligns standard natural substances, while lime-assisted HTH products, applied at level 0.01% w/w, could enhance wheat growth nutrient uptake control group. Importantly, these show no toxicity Daphnia magna, underscoring their potential for sustainable agriculture.

Future Directions of Sustainable Resource Utilization of Residual Sewage Sludge: A Review

Sustainability, Год журнала: 2024, Номер 16(16), С. 6710 - 6710

Опубликована: Авг. 6, 2024

With the simultaneous increase in wastewater generation and treatment rates China, annual production of residual sewage sludge (RSS) has been steadily rising, exceeding 70 million tons with an 80% moisture content. The sustainable resource utilization RSS will be predominant disposal method instead sanitary landfilling China. This review aimed to systematically analyze major technologies for RSS. Firstly, basic characteristics China were analyzed. A comparative analysis was conducted assess advantages, disadvantages, applicability three primary RSS: building materials, energy utilization, phosphorus recovery, aiming provide clear insights development future strategies. research findings revealed that no single can economically environmentally address all challenges resources. It is necessary adopt appropriate according from treatment, achieving integration pollution control utilization. scientific guidance
