“…The biogas emission, mainly CO2 and methane, is a process within the organic matter degradation and contributes to atmospheric pollution and, especially, to greenhouse effect and global warming (Mouhoun-Chouaki et al, 2019;Riaz, 2021). Other gases are produced in the decomposition process of organic matter such as ammonia, sulfide, and 94 non-methane volatile organic compounds were found in air emissions from MSW landfills such as benzene, toluene and chloroform (Zhentong et al, 2013;Fan et al, 2021). Landfills are great contributors to global warming.…”

“…The composting process provides a consortium of microorganisms that are antagonistic to pathogens that are killed by competition and antibiotic effect of inhibiting substances produced by compost microorganisms. High temperatures and microbial diversity in the composting process kill weed seeds and eliminate most pests, human and plant pathogens, parasites and undesirable insect larvae (Hadar and Papadopoulou, 2012;Fan et al, 2021;Abdellatif et al, 2011).…”

Yard waste consist of garden waste, generated by public parks and private gardens routine maintenance such as grass clippings, leaves from deciduous trees, flowers, fallen fruits, branches, twigs and logs and its composition vary greatly depending on the original location due to climate and other environmental conditions. Yard waste may represent a problem to Municipal Solid Waste Management Programs due to its large volume thus, it is necessary to incentivize local composting programs. In this study we show a brief disposal cost estimation from different cities from United States of America and Canada and we discuss how this biowaste can be managed in order to reduce costs with storage, transportation and disposal fees, encouraging the utilization of the final product as a soil amendment, stimulating and reinforcing the circular economy concept. The composted yard waste may not substitute the use of commercial products but it can reduce the cost of acquisition of this soil conditioner as well costs waste management. Update in environmental public policies is essential to foment sustainable economy in this context.

“…In practice, organic wastes, including kitchen waste and livestock manure, are combined with bulking agents (e.g., garden waste and cornstalks) for composting to produce organic fertilizers. , Given their uneven physicochemical characteristics, such as compactness and high moisture content, to limit air diffusivity, organic wastes inevitably form anoxic and anaerobic regions inside aerobic composting piles. These regions favor the proliferation of nitrifiers and denitrifiers for N 2 O emission from composting, particularly after the thermophilic stage .…”

Composting is widely used for organic waste management and is also a major source of nitrous oxide (N 2 O) emission. New insight into microbial sources and sinks is essential for process regulation to reduce N 2 O emission from composting. This study used genome-resolved metagenomics to decipher the genomic structures and physiological behaviors of individual bacteria for N 2 O sources and sinks during composting. Results showed that several nosZ-lacking denitrifiers in feedstocks drove N 2 O emission at the beginning of the composting. Such emission became negligible at the thermophilic stage, as high temperatures inhibited all denitrifiers for N 2 O production except for those containing nirK. The nosZ-lacking denitrifiers were notably enriched to increase N 2 O production at the cooling stage. Nevertheless, organic biodegradation limited energy availability for chemotaxis and flagellar assembly to restrain nirKS-containing denitrifiers for nitrate reduction toward N 2 O sources but insignificantly interrupt norBC-and nosZ-containing bacteria (particularly nosZ-containing nondenitrifiers) for N 2 O sinks by capturing N 2 O and nitric oxide (NO) for energy production, thereby reducing N 2 O emission at the mature stage. Furthermore, nosZII-type bacteria included all nosZ-containing nondenitrifiers and dominated N 2 O sinks. Thus, targeted strategies can be developed to restrict the physiological behaviors of nirKS-containing denitrifiers and expand the taxonomic distribution of nosZ for effective N 2 O mitigation in composting.

“…During the composting process, polymeric waste materials are degraded by the growth of various micro-organisms such as fungi and bacteria. This processing method is quite complex in many ways, as it involves a variety of processes ranging from microbiological to thermodynamic, which are mutually dependent [ 7 ].…”

The reusability of by-products in the food industry is consistent with sustainable and greener production; therefore, the aim of this paper was to evaluate the applicability of multiple linear regression (MLR), piecewise linear regression (PLR) and artificial neural network models (ANN) to the prediction of grape-skin compost’s physicochemical properties (moisture, dry matter, organic matter, ash content, carbon content, nitrogen content, C/N ratio, total colour change of compost samples, pH, conductivity, total dissolved solids and total colour change of compost extract samples) during in-vessel composting based on the initial composting conditions (air-flow rate, moisture content and day of sampling). Based on the coefficient of determination for prediction, the adjusted coefficient of determination for calibration, the root-mean-square error of prediction (RMSEP), the standard error of prediction (SEP), the ratio of prediction to deviation (RPD) and the ratio of the error range (RER), it can be concluded that all developed MLR and PLR models are acceptable for process screening. Furthermore, the ANN model developed for predicting moisture and dry-matter content can be used for quality control (RER >11). The obtained results show the great potential of multivariate modelling for analysis of the physicochemical properties of compost during composting, confirming the high applicability of modelling in greener production processes.
