2000/11/1/ · Through studying the dynamic process of simulated hazardous waste decomposition in mesophlic and thermophlic conditions, the optimal composting conditions were 50–60°C pile temperature, about 60% moisture content, 35:1 C/N ratio, 0.05–0.1 Nm 3 h −1 ·m −3 air composting mixture, 7 days retention time in the thermophlic phase and over 20% TOC (Ma

2021/1/15/ · In the past 10 years, the total accumulated pollution N emitted from solid waste system to the environment reached 4.62 Tg N yr −1 in China, of which 4.29 Tg N yr −1 (92.8% of the total pollution N) was emitted to the atmosphere, about 1.9 times of that emitted by the EU in 2000 (2.3 Tg N) (IPCC, 2006).

2024/5/15/ · MFCs are bio-electrochemical systems designed to produce sustainable electricity. It uses electro-chemically active bacteria to generate electricity due to their metabolic activities. MFC is used for biomass oxidation with the help of biological reactions. They can be classified on the basis of types of catalysts used i.e. enzymes or

2023/7/15/ · Compared to traditional composting, vermicomposting is a more effective process of OSW degradation, as earthworms help to digest and transform the waste materials, which are produced at temperatures ranging from 10 °C to 32 °C (Raza et al., 2022). Additionally, vermicomposting has been found to effectively remove heavy metals (HMs) from organic wastes.

2024/12/1/ · According to these results, the two species of bacteria combined significantly impacted the MFC system's capacity to handle food waste, affecting both organic degradation and energy production [31]. As an effective substitute, Liu et al. presented a novel system that combines anaerobic fermentation with a liquid catalytic fuel cell (AFFC), in which the cell's fuel

2024/12/1/ · The primary constraints in the application of composts for planting are related to phytotoxicity. Previous studies showed that high ammonium concentration can reflect potential phytotoxicity (Da Ros et al., 2018).Besides, low molecular acids, including acetic acid, propionic acid, phenolic acid, and so on have opposite influence on seed germination (Wang et al., 2022a).

2025/1/13/ · This study examines nitrogen transformation mechanisms and compost quality in mesophilic aerobic composting of wheat straw, utilizing cow manure as a co-substrate to promote sustainable agricultural waste management. Two composting systems were established: group A (control) and group B (10% cow manure addition by wet weight). The addition of cow manure

2022/7/1/ · The continuous process on the other hand loads the continuous flow of newer food waste and an equal amount of digested waste is removed. For agitation, biogas can be recirculated or mechanical stirrers can be used as well as inoculum can also be added continuously ( Reshmy et al., 2021b , Awasthi et al., 2021c , Yuan et al., 2022 ).

Two kinds of bacteria cooperated to achieve faster degradation of lignocellulose, which was helpful in shortening food waste composting process. In conclusion, TMC inoculation could significantly improve the efficiency of continuous high-temperature composting and food waste compost quality.

2023/11/11/ · The concept of recycling organic matter and waste nutrients back to agricultural land through the process of composting adheres to the basic principle of the circular economy. The studies on composting systems have laid a solid foundation for biodegradable solid waste management, and there are still significant gaps that require attention in future research.

Compost is a self-heating process for organic waste. Microbes are the main executors in composting process. However, due to low temperature in winter and low efficiency of composting, a lot of heat is lost in composting. In this study, taking-out and feed-batch composting method (TFC) can supplement …
