“…The maximum volatile content of 74% was recorded for a C/N ratio of 11.75, whereas the minimum recorded was 65% for a C/N ratio of 30.5. These values are in agreement with the available data [38].…”

“…The individual carbon and nitrogen percentages of waste content were obtained from published data and weighing the different components of the waste. The overall C/N ratio of the waste was determined using Equation ( 8), where C is carbon content, N = nitrogen content, Q n = wet weight, C n = % oF nitrogen, M n = % moisture content [38].…”

Municipal solid waste contains a high percentage of organic waste, and when it is not disposed of, it becomes a threat to the environment by contaminating the air, water, and soil. Composting is one of the recovery techniques in which the end product of waste eventually contributes to the agriculture industry, reducing the harmful effects on the environment. Composting municipal solid waste is a clean and effective technique for waste disposal. The mechanized composting process is carried out by several methods, like the windrow method or the rotary drum method. However, large-scale composting processes involve energy consumption and labor costs for waste preparation and handling. This increases the market cost of compost. Hence, an energy-efficient composting technique with minimum environmental impact is needed. This research work aims to analyze the performance of an energy-efficient spouted bed technique for aerobic composting of municipal solid waste for the first time using spouted bed technology with sand as the bed material. Spouted bed composting handles the waste using a pneumatic method with minimum power consumption in comparison to conventional mechanical methods with windrow processes or rotary composting machines. The experimental procedure involves a test run of waste along with bed material and the collection of temperature variations, pH variations, moisture variations, and volatile matter content during the progression of the composting process. The results of this experimental study on a single batch of waste are then used to analyze the quality of the compost generated and compare it with existing results. Specific energy consumption for the process was less than 800 kJ/ton of raw waste input, which is much less than the energy used for conventional composting techniques. pH, volatile content, moisture, and temperature measurements indicated agreement with the established parameters of the composting process.

“…In this study, the whole composting process could be divided into four phases, namely, mesophilic phase (21-40 • C, days 0-1), thermophilic phase (35-65 • C, days 2-17), cooling phase (65-40 • C, days [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] and maturation phase (40-25 • C, days 36-43) according to the temperature variation trend of composting. These are consistent with other researcher's results [45].…”

“…Therefore, turning is needed to achieve a homogeneous fermentation process [16] and ensure the abundant oxygen of the compost [17]. Previous research demonstrated that there was a strong relationship between turning frequency (TF) and some physicochemical indicators of compost or compost maturity [18,19]. For instance, the TF could affect total bacterial abundance, TN, temperature, pH, content of moisture, ratio of C/N and germination index (GI) of composting piles [19][20][21].…”

Here, we investigated the impact of different turning frequency (TF) on dynamic changes of N fractions, NH3 emission and bacterial/archaeal community during chicken manure composting. Compared to higher TF (i.e., turning every 1 or 3 days in CMS1 or CMS3 treatments, respectively), lower TF (i.e., turning every 5 or 7 days in CMS5 or CMS7 treatments, respectively) decreased NH3 emission by 11.42–18.95%. Compared with CMS1, CMS3 and CMS7 treatments, the total nitrogen loss of CMS5 decreased by 38.03%, 17.06% and 24.76%, respectively. Ammonia oxidizing bacterial/archaeal (AOB/AOA) communities analysis revealed that the relative abundance of Nitrosospira and Nitrososphaera was higher in lower TF treatment during the thermophilic and cooling stages, which could contribute to the reduction of NH3 emission. Thus, different TF had a great influence on NH3 emission and microbial community during composting. It is practically feasible to increase the abundance of AOB/AOA through adjusting TF and reduce NH3 emission the loss of nitrogen during chicken manure composting.

“…A partir dos dados de produção da safra de 2020, é possível estimar uma geração de TF de quase 20 milhões de t ano -1 (PRADO; CAIONE; CAMPOS, 2013;CONAB, 2020). A vantagem desse tipo de resíduo é sua uniformidade, porém o alto teor de umidade inviabiliza o transporte e uso em áreas distantes (SOTO-PAZ et al, 2020). Quando a TF é utilizada na forma "in natura", emite quantidades significativas de gases de efeito estufa (GEE) como CO2, CH4, N2O (SIQUEIRA NETO et al, 2016).…”
