Lime-assisted hydrothermal humification and carbonization of sugar beet pulp: Unveiling the yield, quality, and phytotoxicity of products

Biofuel Research Journal, Год журнала: 2024, Номер 11(01), С. 2025 - 2039

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.

Maximizing the value of liquid products and minimizing carbon loss in hydrothermal processing of biomass: an evolution from carbonization to humification

Biochar, Год журнала: 2024, Номер 6(1)

Abstract Hydrothermal carbonization (HTC) converts wet biomass into hydrochar and a process liquid, but aromatic compounds in the products have been reported as roadblock for soil applications they can inhibit germination, plant growth, microbial activity. Here, we compared HTC hydrothermal humification (HTH) of cow manure digestate while varying initial alkaline content by adding KOH. HTH converted 37.5 wt% feedstock to artificial humic acids (A-HAs) found both solid twice that HTC. reduced phenolic furanic over 70% solids 90% liquids. The A-HAs resemble natural (N-HA), based on FTIR, UV–vis spectra, CHN XRD analysis. liquid possesses 60% higher total organic carbon (TOC) than Although one-third TOC be precipitated A-HA, high concentration remains which is shown mainly acids. Therefore, also evaluated liquids anaerobic biomethane production, original digestate, increased methane yield 110.3 158.6%, significant enhancement relative 17.2% increase seen with liquid. strong reduction during biogas production from indicates potential converting soluble byproducts methane, maintaining levels product.

Potential of Compost and Spent Coffee Grounds as Sources of Humic-Like Substances: Extraction Modeling and Optimization by Fractional Factorial Design

ACS Omega, Год журнала: 2025, Номер unknown

Опубликована: Апрель 11, 2025

Humic substances (HSs) play a crucial role in soil health and have potential applications beyond agriculture. This study evaluates the renewable raw materials such as compost from urban green waste (GWC) spent coffee grounds (SCG) sources of humic-like (HLSs), which may be an alternative to traditional resources peat, lignite, leonardite. The quantitative analysis focused on modeling optimizing efficiency ultrasound-assisted extraction acids (HLAs) function time, ultrasound intensity, extractant concentration (NaOH), temperature. Experimental points were determined based experimental matrix according fractional factorial design (FFD), obtained polynomial models evaluated using Fisher test, lack fit assessment, determination coefficients. verification with optimal values parameters demonstrated possibility extracting HLAs GWC SCG at levels 27.08 19.11%, respectively. qualitative included fulvic-like their comparison reference samples. Spectroscopic methods (UV-vis, ATR-FTIR, CP/MAS, 13C NMR) well elemental (CHNSO) used this part study. results showed presence functional groups characteristic humic (polysaccharides, phenols, alcohols, amides) molecular structure products. Additionally, they exhibited higher content nitrogen sulfur compared commercial samples, lower hydrophobicity, indicate biological activity.
