2024/10/9/ · This study investigated treatment for urban wastewater sludge, specifically examining natural drying over five years, accelerated freeze–thaw–drying cycles, and composting with and without a zeolite additive. The findings reveal that composting effectively stabilized the sludge while retaining essential nutrients crucial for agriculture. Notably, with the

of proven processing technologies, biogas utilization, facility design, odor control, and compost quality, as well as other related issues such as procurement approaches and system selection. It is hoped that readers will benefit from this compendium of knowledge and lessons learned to support further efforts to reduce

An innovative biodrying-enhanced composting (BEC) system that applies biodrying to composting process as its start-up stage was developed to rapidly process kitchen waste (KW) into highly maturate products. The BEC performance and potential mechanisms of rapid start-up and humification were explored through a continuous pilot experiment. The results showed that the

2023/3/1/ · This study was focused on the changes of hydrogen sulfide (H 2 S), its precursors, and microorganisms associated with its transformation during the composting process of kitchen waste. The results showed that the content of cysteine (Cys) and methionine (Met) decreased by 32.3 % and 57.5 % respectively, while the content of sulfate (SO 4 2-) changed

2021/6/1/ · The heating system was designed to provide the thermophilic temperature in the range of 50 - 65 °C. The kitchen-waste composting process was conducted in parallel in two fabricated kitchen ...

2023/1/1/ · During the past few decades, the generation of organic solid waste worldwide saw a continuous increase with the soaring population and increasing society wealth [6].It was estimated that the annual production of OSWs would rise to over 3.4 billion tons in 2050 with countries in Asia and Africa being the important growth polarity [7].However, the current waste

Home » News » Commercial Composting Tower » Bacteria-enhanced Composting System manufactured in China with high-quality materials Cattle manure compost humification process by inoculation 2022/1/1/ · The humus is produced through the condensation of nitrogen-containing compounds with other precursors.

2021/7/22/ · Composting of food processing waste was analyzed as a biological process and an engineered system. The goal is to establish fundamental principles and design criteria that would aid its adoption as waste management practice. diversity will be a fundamental goal in all aspects of composting design; in this system, its importance is ...

2024/12/21/ · Agricultural activities generate substantial quantities of waste, which are often relegated to landfills or incineration. However, these residues can be effectively valorized through composting, which transforms them into valuable organic fertilizers (OF). Composting agricultural waste (AW) mitigates environmental impacts and offers significant benefits in enhancing soil

2023/5/1/ · This study aimed to explore the effect of phosphate-solubilizing bacteria (PSB) Bacillus inoculation in the cooling stage on hydroxyapatite dissolution, phosphorus (P) forms transformation, and bacterial P cycling genes in food waste composting with hydroxyapatite. Results indicated that PSB inoculation promoted the dissolution of hydroxyapatite, increased P

2025/2/2/ · Composting converts organic agricultural wastes into value-added products, yet the presence of significant non-biodegradable lignocelluloses hinders its efficiency. The introduction of various exogenous microbial agents has been shown to effectively addresses this challenge. In this context, basing on the microbial enzymatic mechanism for lignocellulose

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 …

of heat produced is determined by factors such as feedstock energy content, feedstock degradability, duration of composting, and the conditions prevailing during composting (e.g., moisture, temperature, sub-strate consistency, and particle size). Estimates of energy release vary with the feedstock and how inves-tigators characterize the energy.

2024/12/1/ · One of the primary parameters monitored during the composting process was temperature. Its fluctuations can indicate the degradation of OM and microbial activity and can also be utilized as an indicator to assess the safety of the composting process [16], [17]. The temperature of each treatment was elevated to 50 °C on day 1, and the duration
