Effect of fermentation materials reflux on gaseous emissions during perishable waste composting

Environmental Technology & Innovation, Год журнала: 2024, Номер 33, С. 103530 - 103530

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.

Microbial Agents Assisted Aerobic Co-Composting of Sheep Manure and Furfural Residue: Maturation Enhancement and Microbial Dynamic

Опубликована: Янв. 1, 2025

The effects of different proportions sheep manure (SM) and furfural residue (FR) adding microbial agents (MA) on compost maturity, substance transformation bacterial-fungal communities were investigated. Four groups designed with low FR ratio (13SM+FR, 13SM+FR+MA) high (SM+FR+MA, SM+FR), among them, SM+FR+MA 13SM+FR+MA both added 0.4% MA. results showed that after 30-days pile composting, all treatment met the requirements for indicating combined composting SM feasible. High ratios addition MA can significantly enhance temperature prolong thermophilic phase during process. more conducive to decomposition organic matter (OM) maturity. Adding promotes metabolism carbohydrates proteins by altering activity enzymes in phase, while weakening pathways such as biosynthesis secondary metabolites carbon cooling maturation phase. In contrast MA, adjusting proportion raw materials easier effective reshape composting. addition, reduce abundance pathogens Rhodotorula, Exophiala, Scythalidium, Lecythophora. Therefore, process, be directly used a conditioner higher increase C/N are strategies inhibiting enhancing

The Evolution of Nutrient and Microbial Composition and Maturity During the Composting of Different Plant-Derived Wastes

Biology, Год журнала: 2025, Номер 14(3), С. 268 - 268

Опубликована: Март 6, 2025

Composting is an environmentally friendly treatment technology that recycles and sanitizes organic solid waste. This study aimed to assess the evolution of nutrients, maturity, microbial communities during composting different plant-derived wastes. The process was conducted over 49 days using three types waste: wheat bran (WB), peanut straw (PS), poplar leaf litter (PL). examined through physical, chemical, biological parameters. results revealed after composting, groups experienced significant changes. They were odorless, insect-free, exhibited a dark brown color, had alkaline pH value, electrical conductivity (EC) value less than 4 mS/cm. These characteristics indicated they reached maturity. Nutrient content most factor influencing degree humification materials, while changes in community diversity key driving factors. Significantly, compost PS, derived from straw, entered thermophilic phase first, by end it lowest matter (OM) loss rate (17.4%), with increases total nitrogen (TN), phosphorus (TP), potassium (TK) order PS > PL WB. increase humus carbon (HSC) humic acid/fulvic acid (HA/FA) ratio followed WB PL. FTIR spectra greater aromatic compared other samples. abundance bacterial fungal increased significantly, accompanied more complex structures. Crucially, there no phytotoxic effects any treatments, boasted high germination index (GI) 94.79%, heavy metal contents. findings indicate has highest potential for resource utilization suitable agricultural applications. Our demonstrate waste enhance soil fertility provide reference
