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.

Hydrothermal carbonization (HTC) is a promising thermochemical process to convert residues into hydrochar. While conventional HTC utilizes one type of residue as raw material only, Co-HTC generally combines two. By mixing dry and wet wastes, can advantageously avoid water addition. Therefore, this work investigated the potential hydrochar derived from sawdust non-dewatered sewage sludge dye (methylene blue) adsorbent evaluated toxicity resulting (PW) on Daphnia magna. Three hydrochars were produced by at 180, 215, 250 °C named H-180, H-215, H-250, respectively. For methylene blue adsorption, H-180 H-215 had better performance than H-250. Both presented maximum adsorption capacity approximately 70 mg·g−1, which was superior compared with other in literature. Moreover, removal percentage obtained remained satisfactory even after five cycles. Regarding toxicological assays PWs, raising temperature increased variety substances PW composition, higher D. The EC50 values PW-180, PW-215, PW-250 1.13%, 0.97%, 0.51%, This highlights importance searching for treatment valorization PW. Instead viewing by-product an effluent be treated disposed of, it imperative assess PWs obtaining added-value products.

The treatment of dairy industry effluents poses a significant challenge from the environmental point view because its high organic load. In this work, aqueous phase reforming lactose was investigated as representative model compound for production renewable hydrogen. tests were conducted using two different scenarios: first one is referred to direct (APR); second proposed pre-hydrogenation step, followed by APR. implementation reactive pretreatment allowed minimizing solid by-product formation with respect APR, where most initial carbon ended up residue. in range 180–220 °C, Ru-based catalysts. best scenario (using 5% Ru/C), reduced 95%, and 70% converted into gaseous compounds, hence contributing removal content wastewater while producing an energy carrier. Moreover, hydrogen selectivity increased (with 2.5% APR), thanks hindering homogeneous reaction pathways that do not lead production. Finally, energetic analysis assess possibility coupling APR quantifying percentage which may be produced situ satisfy industrial duties.
