“…As shown in Figure 6, the cumulative biogas production for the reactor (R2(140)) is higher in the untreated reactor with approximately 29.65%, as shown in Figure 7, but the biogas yields in terms of COD removed and VS removed were approximately the same. The biogas yield production resulted in this study is higher than a study of co-digestion of FW and Primary Sludge (PS) which indicated that a mixing ratio of 1:2 produced a maximum biogas yield of 272 ml/ gVS at mesophilic conditions (Marcelo et al, 2017). It is very close to the biogas yield obtained by co-digestion of pretreated OFMSW and sludge with mixing ratio of 1.25:1 (volume ratio) at 65 °C for 60 min by (Amiri et al, 2016) which was 380 ml g -1 COD.…”

In this study, the effect of thermal pre-treatment (TP) on the physical characteristics and co-digestion of a mixture of food waste and sludge was investigated. The food waste (FW) to sewage sludge (SS) ratio used in this research is 1:2 (VS-based) to form a final concentration of 11.20%. The inoculum to substrate ratio was set at 1:1 (volumebased). Undoubtedly, the results show that TP has changed the physical characteristics of the food waste to sewage sludge mixture. The results show that the pretreatment increased the biogas production from 4385 ml for the untreated reactor to 5685 for the reactor R2(140) at 140 °C and the improvement in biogas production reaches 29.65% in the reactor R2( 140) and the removal of volatile solids was 58.90%. Therefore, after the biomethane potential test, the temperature of 140 °C was found to be optimal in the production of biogas. The optimal condition is to use a mixture of pre-treated SS at the temperature of 140 °C and untreated FW, so TP is recommended to be used in anaerobic digestion of the mixture of food waste and sewage sludge.

“…On the basis of the previous studies (Table 1) in this field, the mixing ratio used in this research between the food waste and sludge was chosen according to (Marcelo et al, 2017;Prabhu & Mutnuri, 2016). To determine the optimal ratio of mixing FW with SS for anaerobic co-digestion, a biomethane potential batch was achieved.…”

“…There are few simulations performed for the AcoD process using municipal solid waste organic fractions and sewage sludge via the ADM1 modeling approach (Derbal et al, 2009;Esposito et al, 2011). Simulation studies are available for AD using Aspen Plus software (Rajendran et al, 2014;Aguilar et al, 2017;Ravendran et al, 2019), but limited studies were found in which simulation was used to evaluate AcoD (Nduse and Oladiran, 2016;Inayat et al, 2019;Ankathi et al, 2021). Aspen Plus (AP) software is a chemical process simulator that allows users to design and simulate a process model or improve existing designs using complex equations.…”

Anaerobic digestion (AD) is an established method that has been extensively utilized for waste management, waste treatment, and biogas production. Anaerobic co-digestion (AcoD) is regarded as a practical approach to address substrate characteristics and system optimization issues. The distinction between AcoD and mono-digestion is that AcoD has a higher organic loading and significant substrate composition variation. There are many factors involved in AcoD which affect the biogas plant’s production ability and performance. Using response surface methodology (RSM) to forecast the optimal conditions for maximum biogas output, this article provides an overview of the different operational parameters in the AcoD process, modeling of the AcoD process, and overall process optimization. Standard software used for AcoD process simulation are Aspen Plus, SuperPro Designer, BioWin, CFD, and MATLAB. Review addresses design, development, and optimization frameworks for biogas production systems that take numerous aspects into account. The most significant AcoD optimization parameters include temperature, co-substrate concentration, inoculum ratio (percent), and C/N ratio.

“…Organic waste constitutes an important outcome of human activity, totaling 30% of waste with a 0.8% yearly increase. Traditional landfilling, predominant in developing countries [1] , contrasts with the circular economy's reduce, reuse, recycle, and add value philosophy. Raw organic waste has limited reuse/recycling possibilities, but it has significant energy potential [2] .…”
