“…The RR of N obtained in our study was comparable with the results of these studies [1,13,34]. Moreover, Muhayodin et al [27] used the results of 12 AD experiments with a wide range of substrates, determining an average RR of N of 92.5%, which is comparable to the results…”

Anaerobic co-digestion technology (AcoD) can be used to process rice straw (RS) and cow manure (CoM) to produce energy and a digestate rich in nutrients, while the improper disposal of RS and CoM causes environmental problems. The overall effectiveness of the anaerobic digestion technology can be improved by utilizing the nutrients available in the digestate. It is also a way to reduce the usage of mineral fertilizer by recycling the nutrients available in the digestate. The co-digestion of RS with CoM was performed in a newly developed digester (F1) and in a mesophilic digester (F2) used as a reference. The mass balance of C, macronutrients (N, P, K, Ca, Mg, and S), and their distribution into a liquid digestate (LD) and a solid digestate (SD) was investigated in both digesters. The mass balance was used to evaluate the carbon available in the biogas and in the digestate. It was also used to investigate the recovery potential of the macronutrients after the AD process. Moreover, the assessment of the resulting digestate was carried out to suggest its potential use in agriculture. The amount of C measured in the biogas was the same in both digesters (41.0% and 38.0% of the initial C). Moreover, the conversion efficiency of C from the substrate into methane was 23.4% for F1 and 21.0% for F2. The Ca, Mg, K, and P were conserved in the digestate because their recovery rates (RR) were close to 100%. However, a relatively low RR was observed for N (84.1% in F1 and 86.8% in F2) and S (87.1% in F1 and 86.5% in F2) in both the digesters. After separation n of the SD, from 79.1 to 83.4% (in F1) and 75.0 to 82.4% (in F2) of the final nutrients were available in the LD. The assessment of the SD suggested its use in agriculture not only for soil amendment but also as a K-providing organic fertilizer.

“…The nutrient content of organic substrates determines their biogas quality and quantity. Macronutrient elements must be present in the substrate for microbial growth to occur [11]. Additionally, maximum biogas yield is dependent on adequate and efficient nutrient supply of microorganisms in the digester [11,12].…”

Aim: To investigate the feasibility of producing biogas from anaerobic co-digestion of cotton yarn wastes (CY) and human urine (HU) using fresh cow dung as the inoculum. Study Design: Anaerobic co-digestion of CY waste and HU and CY waste alone were done using batch reactors. Place and Duration of Study: CY were collected from Rivatex Eastern Africa Limited, Eldoret, Kenya while fresh cow manure used as inoculum was collected from a farm at Moi University, Eldoret, Kenya. Human urine sample was collected in a clean sterile container at Moi University hostel, Eldoret, Kenya. The experimental set up and analyses were performed at Chemical and Process Engineering Laboratory, Moi University, Kenya between January 2020 and May 2020. Methodology: CY, HU and fresh cow dung were subjected to physicochemical analysis. Batch anaerobic co-digestion of CY and HU, and CY alone were carried out under ambient temperature (25 ± 3 ) conditions for 95 days and 37 days, respectively. Results: The CY contained 90.46% total solids, 77.12% volatile solids and 9.54% moisture content while the corresponding values for HU were 2.9%, 58.5% and 97.1%, respectively. CY had a high carbon to nitrogen ratio. The biogas yield from anaerobic co-digestion was 35.6% more than digestion of CY alone. The highest daily biogas production for co-digestion and digestion of CY alone were 330 mL and 386 mL on day 12 and 21, respectively. The total biogas yield when CY co-digested for 95 days was 10,125 mL which decreased to 6,519 mL without co-digestion after 37 days. Conclusion: Our results showed that co-digestion produced more biogas than digestion of CY alone. Conclusively, the presence of HU during anaerobic digestion of CY enhanced the biogas production by more than 35.6% demonstrating that HU could be an effective waste for co-digestion of solid wastes such as CY. Further research should focus on monitoring parameters like temperature, buffering capacity and fatty acid levels to ensure optimal efficiency and maximum biogas yield.

“…Even a substantial reduction of greenhouse gases impact is possible if natural and decontrolled anaerobic decomposition is considered as the usual fate of some types of waste (e.g., animal manures or forestry residuals) [2]. In this issue, Muhayodin et al [3] present a global study about the applicability of anaerobic digestion as a process for reducing the greenhouse gases from rice straw as an example of lignocellulosic material including a mass balance for nutrients. The anaerobic digestion of rice straw is a clear case of reducing the impact of greenhouse gases.…”
