Phosphorus applications in agriculture can lead to significant environmental impacts, necessitating a revolution current agricultural practices. This study explores the potential of hydroxyapatite nanoparticles (nHAPs) synthesized from poultry bones as P fertilizers. nHAPs were produced at 300 °C (nHAP300) and 700 (nHAP700), their effectiveness was evaluated. An vitro solubilization test with Pseudomonas alloputida evaluated bacterium's ability solubilize nanoparticles, assessing dissolved organic acids produced. Additionally, soil leaching measured losses bioavailable compared conventional fertilizer, triple superphosphate (TSP). nHAP300 displayed heterogeneous sizes, while nHAP700 approximately 100 nm size, content 8.8% 19.4%, respectively. successfully solubilized both types demonstrating higher solubility than nHAP300. The TSP treatment resulted (6.35 mg) nHAP treatments (nHAP300 0.32 mg; 0.28 mg), indicating for recycling waste. Our findings indicate that are more efficient release but less prone Utilizing these enables phosphorus recovery waste holds sustainable applications.

Abstract Large amount of wastes are burnt or left to decompose on site at landfills where they cause air pollution and nutrient leaching groundwater. Waste management strategies that return these food agricultural soils recover the carbon nutrients would otherwise have been lost, enrich improve crop productivity. The incorporation liming materials can neutralize protons released, hence reducing soil acidity its adverse impacts environment, security, human health. Biochar derived from organic residues is becoming a source input provides multifunctional values. be alkaline in nature, with level alkalinity dependent upon feedstock processing conditions. This study conducted characterization biochar pyrolysis process eggplant Acacia nilotica bark temperatures 300 °C 600 °C. An analysis was kinds determine their pH, phosphorus (P), as well other elemental composition. proximate by ASTM standard 1762-84, while surface morphological features were measured using scanning electron microscope. exhibited greater yield higher fixed possessing lower content ash volatile components compared eggplant. exhibits ability acacia bark-derived biochar. calcium carbonate equivalent, potassium (K), (P) levels biochars increased temperature increased. results suggest could beneficial resource for storing soil, addressing enhancing availability, particularly acidic soils.

Hydrochar as a carbon-based fertiliser is hypothesised to permanently improve soils by modifying soil carbon quality through the regulation of organic dynamics, aggregation properties and microbial diversity. However, interactions between (SOC) molecular structure, aggregates communities result hydrochar application have not been fully elucidated. In this study, use derived from duck farm biomass waste for maize cultivation experiment verified that had promoting effect on growth, effectively increasing nutrient supply soil. The increased content 78 253 per cent, which was dominated CHON-type lignin, carbohydrates condensed aromatic structural compounds. Meanwhile, significant both structures oxygenated functional groups, forming more macroaggregates. addition, positive bacterial abundance. This study suggests key mechanism regulates dynamics mainly stabilising macroaggregates while abundance carbon-related microscopic bacteria. These results will help elucidate potential effects aqueous biogeochemical cycling in soils.

Abstract Ammonia inhibition poses a significant challenge to the efficient and stable operation of anaerobic digestion (AD) systems by leading volatile fatty acid conversion reduced methane production. This study explores utilization lignin-based hydrochar (LHC) carbon quantum dots (CQDs) produced via hydrothermal carbonization alkali lignin alleviate ammonia in AD processes. The results showed that both LHC CQDs help counter decline yield production rate typically associated with inhibition. Notably, addition 1 g/L significantly increased 24.25% compared control group. While limited adsorption, its primary impact was enhancing direct interspecies electron transfer (DIET) through improved redox capacity promoting humic acid-like organics formation. In contrast, charge resistance, system capacity. Optimizing temperature 250 °C further optimized properties, boosting 30.53% at concentration 3 g/L. Microbial community metabolic pathway analyses indicated enriched hydrolytic acidifying bacteria, as well DIET-associated microorganisms, facilitating conversion. process enabled sustained acetoclastic hydrogenotrophic methanogenic pathways, effectively mitigating adverse effects high nitrogen concentrations.

Enhancing Fuel Properties and Energy Performance with Co-Hydrothermal Carbonization of Coffee Waste and Swine Manure

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Апрель 28, 2025

This study evaluates the fuel properties and energy performance of hydrochar produced through co-hydrothermal carbonization (Co-HTC) swine manure (SM) coffee waste (CW). The effects reaction temperature (160°C, 200°C, 240°C) mixing ratio (SM:CW = 1:1, 3:1, 5:1) on combustion characteristics, densification (EDR), yield (EY) were analyzed. results indicate that Co-HTC effectively enhances quality by leveraging synergistic interactions between SM CW. At 240°C a 1:1 ratio, exhibited characteristic index (S) 9.1 × 10⁻⁹ %²/min²·°C³, an EDR 1.39, EY 57%, demonstrating superior performance. high lignin content in CW promoted fixed carbon retention, while elevated nitrogen contributed to potential agricultural applications. Additionally, reduced O/C H/C atomic ratios, resulting enhanced density. Despite increase ash with higher values remained across all conditions, maximum 61.8% at 5:1 suggesting retention was not significantly hindered. These findings confirm is viable approach converting organic into high-energy-density solid fuel, offering sustainable solution for bioenergy production valorization.
