“…Although the isolated effects of turning frequency (GETAHUN et al, 2012;COOK et al, 2015), environmental conditions concerning the presence or absence of cover (MAREŠOVÁ & KOLLÁROVÁ, 2010) and use of inoculum (XI et al, 2012;JIANG et al, 2015a) are known in the composting process, the integrated effect of these factors in the composting time of the agroindustrial wastes become an important information, mainly to composting plants.…”

ABSTRACT:The agro-industrialization of animal products has led to a significant waste generation, which has been stabilized by composting process in specialized plants. Waste stabilization time on composting depends on the handling used. 12 treatments were performed, three frequency turnings combined with two environmental conditions (with and without coverage of the composting area) and with and without commercial inoculant, whose results were submitted to multiple regression analysis. Windrows turned twice a week in the first month had adequate temperature control and stabilization time of 83.5 and 95.5 days for uncovered and covered windrows, respectively. Uncovered windrows have accelerated the process in 10 days on average, with the disadvantage of increasing nutrient losses. The weekly inoculation of Bacillus (subtilis, licheniformis and polymyxa) and Yarrowia lipolytica had no significant effect (p≥0.05).

“…According to the literature (Marešova et al, 2010), temperature is considered as the most important indicator of the efficiency of the composting process. Temperature variation over time influences the rate of the composting process and it is important for the production of stable compost (Marešova et al, 2010). Temperature evolution during composting can be divided into four phases, namely, mesophilic, thermophilic, cooling, and maturation stage (Onwosi et al, 2017).…”

“…The effectiveness of the composting process is influenced by environmental parameters (temperature, moisture, pH, aeration) and substrate parameters (C/N ratio and nutrient content). The correct control of the process contributes to obtaining a stable, storable, and transportable final product that is suitable for soil application (Cosenza et al, 2018; Marešova et al, 2010). Compost can be considered a sustainable product that directly and indirectly influences the physical, chemical, and biological fertility of soil (Siles-Castelano et al, 2020).…”

An enhanced composting process with bioaugmentation: Mathematical modelling and process optimization

et al. 2021

View full text Add to dashboard Cite

In this paper, two different types of biowaste composting processes were carried out – composting without and with bioaugmentation. All experiments were performed in an adiabatic reactor for 14 days. Composting enhanced with bioaugmentation was the better choice because the thermophilic phase was achieved earlier, making the composting time shorter. Additionally, a higher conversion of substrate (amount of substrate consumed) was also noticed in the process enhanced by bioaugmentation. A mathematical model was developed and process parameters were estimated in order to optimize the composting process. Based on good agreement between experimental data and the mathematical model simulation results, a three-level-four-factor Box-Behnken experimental design was employed to define the optimal process conditions for further studies. It was found that the air flow rate and the mass fraction of the substrate have the most significant effect on the composting process. An improvement of the composting process was achieved after altering the mentioned variables, resulting in shorter composting time and higher conversion of the substrate.
