The Use of New Parameters to Optimize the Composting Process of Different Organic Wastes

Abstract: The correct development of the composting process is essential to obtain a product of high value from organic wastes. Nowadays, some composting mixture parameters (i.e., air-filled porosity, moisture and the C/N ratio) are used to optimize the composting process, but their suitability is still debated because the literature reports contrasting results. This paper aimed to find other parameters that control the correct development of composting. The relationship between these and the compost quality was then ve… Show more

“…It is well known that its high temperature can kill pathogenic bacteria, weed seeds and other harmful substances, and accelerate physiological and biochemical reactions due to the exothermic nature of aerobic composting ( Sahlström, 2003 ). Composting temperature is usually used as a progress index ( Pezzolla et al., 2021 ). Generally, the composting temperature is higher than 55°C for 3 days to meet the composting requirements ( Xu et al., 2019 ).…”

“…The changes in ARGs abundance during storage or composting may vary depending on the location of the long-term storage pit or composting pile, storage/composting time (age), manure removal techniques (scrap versus flush removal) or even season of storage (Hurst et al, 2019). In addition, during composting, ARGs and MGEs removal can also be influenced by temperature, pH, moisture, or type of waste and bulking material (Pezzolla et al, 2021). In addition, ARGs levels can also depend on the co-occurrence of ARGs or MGEs, and on various factors affecting bacterial fitness, gene regulation and transfer, such as nutrient accessibility or heavy metal concentration (Oliver et al, 2020).…”

“…The correct development of composting depends on its active and curing phase. Pezzola et al (Pezzolla et al, 2021) demonstrated that the maximum attainable temperature, the time to reach it, and the pH and moisture depend on the used waste type and bulking agents. In addition, the dynamics of antibiotics removal appear to be closely influenced by the choice of bulking agent (sawdust rice husk, mushroom residues) (J.…”
