Aiming at the problems of low bioconversion efficiency and serious secondary pollution urban perishable waste (PW), fermentation materials reflux was applied in PW composting to investigate effects modes on emission ammonia (NH3), methane (CH4) nitrous oxide (N2O) this study. Before that, 20% determined be optimal ratio terms indicators gaseous emissions used current experiment. Five treatments including CK (no-reflux), T1 (reflux mature compost (MC), completely mixed with initial material), T2 MC, 15% for mixing, 5% surface covering), T3 10% covering) T4 thermophilic (TC) TC MC covering). reduced NH3 CH4 by 52.9% 40.11%, as a result high temperature inhibition methanogens former stage. While most N2O 56.85% through restraint denitrification. In conclusion, introduction can accelerate process, improve maturity, mitigate greenhouse gas (GHG) ranging from 27.61% 58.05%, which provide theoretical technical support rapid future.

Characteristics of industrialized hydrothermal cracking solid organic fertilizer and its effects on fresh corn growth

Waste Management, Год журнала: 2024, Номер 177, С. 243 - 251

Traditional methods of producing organic fertilizers result in significant nutrient loss and greenhouse gas emissions, making it challenging to align with sustainable development the achievement net-zero emissions goals. Hydrothermal cracking, as a novel clean technology for utilization waste into fertilizer, has been extensively studied refined laboratory settings, but its large-scale industrial evaluation remains limited. This study investigates properties field application hydrothermal cracking solid fertilizer (HCSOF) produced at pilot scale an annual output 10,000 tons. The results indicate that matter content total (TN + P2O5 K2O) HCSOF reached 50.6 % 5.46 %, respectively, which are 20.6 1.46 higher than standards China. Additionally, contaminants such pathogens antibiotics product were completely eliminated. Elemental analysis pore size distribution highlighted unique adsorptive attributes HCSOF, showed effect reducing soil ammonium nitrogen. Results from trials complete substitution chemical did not reduce corn yield, remained 9.03 t/ha. Particularly, compared exclusive use fertilizers, treatments resulted 7.03 4.70 decrease fresh lodging disease incidence, respectively. Antibacterial tests further confirmed ability counter pathogens. provides robust evidence scaling up production levels. Future research should focus on multi-batch sampling extended experiments.

Nitrogen fixation and calcium activation of oyster shell during composting and its performance on acidic soil amendment

Environmental Technology & Innovation, Год журнала: 2024, Номер 36, С. 103792 - 103792

Chicken manure, corn straw and oyster shell powder (OSP) were used as raw materials for organic-inorganic combined composting. Experiments designed by adding different amounts of OSP (0 %, 20 40 %), CK, T1, T2, respectively. In final composts, the pH value increased to 8.72–9.08, electrical conductivity ranged from 2.08–3.82 mS·cm−1. The co-composting could effectively reduce ammonia emissions 54.65 % activate calcium component 37.5 %. Addition promoted humification humic acid 86.1 This calcium-based compost shells (OSs) activated composting was plant Brassica napus pot experiment. Compared with addition after composting, significantly growth because more nitrogen, humus available in compost. addition, this pH, organic matter (OM) exchangeable content acidic soil. general, is an effective method realize fertilizer utilization OSs. process make full use achieve nitrogen retention enhancement during meanwhile morphology can be high-quality soil conditioner obtained.
