2024/2/15/ · This phenomenon may be due to the early stage of simulated composting, sufficient carbon source in the raw material can provide energy for bacteria repair of damage [15], and organic matter will also consume most of the ROS, avoiding direct damage to bacteria by ROS [23], [9]. In the later stage of simulated composting, the metabolic reproduction of

2022/9/1/ · Technology development based on research and innovation activities is going to play a crucial role in improving the role of composting and vermicomposting practices during the transition to a circular economy and to obtain high-quality natural fertilizers for sustainable agricultural practices (Awasthi et al., 2022c).Patents related to compost technology often focus

2024/4/1/ · In particular, due to its efficacy in enhancing compost maturation and greenhouse gas emission reduction, SMHC has attracted attention in both research and practical applications (González et al., 2016; Levis and Barlaz, 2011).Fig. 1 c shows the three primary components of the SMHC: the semi-permeable membrane covering system, the micro-pressure air delivery

2023/11/1/ · Mature compost reduced the total global warming potential (GWP) by 25.91 % via inhibiting the activity of bacteria related to the production of CH 4 and N 2 O. Functional Annotation of Prokaryotic Taxa (FAPROTAX) further revealed that mature compost addition increased relative abundance of bacteria related to multiple carbon (C) cycle functions such as

The composting of lignocellulosic oil palm empty fruit bunch (OPEFB) with continuous addition of palm oil mill (POME) anaerobic sludge which contained nutrients and indigenous microbes was studied. In comparison to the conventional OPEFB composting which took 60-90 days, the rapid composting in this study can be completed in 40 days with final C/N ratio of 12.4 and nitrogen

2024/2/1/ · As the composting temperature rises, organic acids volatilize, and organic carbon mineralizes, increasing the pH of the aerobic composting system (Mo et al., 2023), and the final pH values for all groups remain weakly alkaline. The pH values were below 7.0, from the feeding stage to the high-temperature stage, and increased significantly during the high-temperature

2022/9/15/ · The nitrogen loss of SS composting is predominantly generated in the gaseous forms (NH 3, N 2 O, NO, etc.), NH 3 emissions are typically ascribed to the rapid transformation of ionized ammonium (Shou et al., 2019).Nitric oxide (NO) odors are critical precursor matters to tropospheric ozone, and the NO odor emissions may cause the formation of acid rain and

2020/10/1/ · Approximately 5.7 billion metric tons (t) of organic wastes are produced every year in China, of which approximately 3.8 billion t is animal manure (fresh excreta), 1 billion t is crop straw, and 0.1 billion t is green manure (plant residues) (Niu and Ju, 2017).Inappropriate utilization of such a large amount of organic material not only wastes valuable resources, but

2023/11/1/ · Phosphorus bioavailability is essential for assessing compost quality. However, the effects of microbial and environmental factors on potentially active phosphorus (H 2 O-P + NaHCO 3-Pi) in factory compost have not been investigated.The findings indicated that chicken manure had significantly higher available phosphorus (AP) and H 2 O-P + NaHCO 3-Pi

Indigenous cellulolytic and hemicellulolytic bacteria enhanced rapid co-composting of lignocellulose oil palm empty fruit bunch with palm oil mill effluent anaerobic sludge Mohd Huzairi Mohd Zainudin

2025/1/1/ · The shifts in P fractions accompany variabilities of bacterial communities in composting systems of crop straws (Sarr et al., 2020), animal droppings (Wu and Wan, 2023), kitchen wastes (Zhan et al., 2021), and activated sludge (Yang et al., 2024).The α- and β-diversities reflecting landscape pattern of bacteria display notable changes during composting …

In China, trough composting system and windrow composting system are the main compost- ing processes, with windrow composting system being more popular in Jiangsu Province (Figure 3). Windrow

2025/2/1/ · Similarly, Li et al. (2024) showed that adding PET hydrolase to high-temperature composting systems significantly enhanced PET degradation, reduced thermophilic microbes, and enriched potential PET-degrading bacteria such as Acinetobacter and Bacillus, which belong to the Gammaproteobacteria and Bacilli classes, respectively, also identified in our study. While …
