“…The original data is further processed to generate median, maximum, minimum, and quartiles as shown in Figure 2. Box plots of TS and VS are smaller, and the whiskers do not extend as far, indicating that these properties do not differ much over the various analyzed studies, while the C/N ratio is different for the RS used in these studies with spread-out data points [10,26,28,[36][37][38][39][40][41][42].

“…AD is an appropriate technology to convert agricultural residues into biogas [37] and to transform the nutrients contained in the substrates into plant-available forms so that the final digestate can be used as fertilizers [43,44]. The effective use of nutrients available in the digestate is a way to improve the overall efficiency of AD technology [37]. The mass balance of nutrients in the AD is crucial for the quantification of their recovery potential [45].…”

“…The mass balance of nutrients has been investigated in the AD of different substrates [37,[46][47][48][49]. The recovery rate (RR) of nutrients is defined as the amount of nutrients available in the digestate after the AD process relative to their initial value (before the AD) and expressed as a percentage (%) [37]. The RR is usually calculated by the authors and provided in the studies.…”

Open field burning and tilling the rice straw (RS) back into the fields causes environmental threats by contributing to the increased greenhouse gas emissions. Energy and nutrient recovery from RS through anaerobic digestion (AD) is an effective solution for its utilization. Although RS has good methane potential, its characteristics make it a difficult substrate for AD. This paper reviews the characteristics of RS, mass balance, and distribution of nutrients into liquid and solid digestate in the AD. The present review also discusses the effect of temperature, co-digestion, mixing, inoculum, organic loading rate, recycling liquid digestate, the addition of trace elements, and their bioavailability on the enhancement of biogas/methane yield in the AD of RS. In addition, the digestion of RS at various scales is also covered in the review.

Use of membrane filtration is attracting increasing attention for nutrient recovery from anaerobically digested slurry. However, the challenge is to reduce membrane fouling by effective solids mitigation, while maintaining valuable nutrients. In this study, the effects of several flocculation pre-treatments using polyaluminium chloride, iron chloride, and flocculant aid at various dosages were investigated. The results showed significant improvement in membrane flux from 0.8 to 27.6 mL/m 2 /s due to solid 2 migration (up to 75% removal). Significant loss of PO4 3− -P (99%) and humic acids (40-80 %) was observed. However, the content of NH4 + -N and indoleacetic acids was largely maintained in the treated slurry. Moreover, toxic metals were significantly removed through flocculation, making the final product risk-free of heavy metals for agricultural application.

Control Strategies for Enhanced Biogas Production from Chicken Manure

et al. 2023

View full text Add to dashboard Cite

The control strategies adopted in formulation and anaerobic digestion (AD) process of chicken manure (CM) for the control and enhancement of biogas production are reviewed. The existing limitations and future challenges in the production of biogas from AD of CM are briefly discussed. The control strategy adopted for formulation is pretreatment of CM (physical, chemical, biological, and thermal) while strategies for AD include selection of optimal parameters (pH, C/N ratio, organic loading rate (OLR), and temperature), co‐AD with other substrates, and addition of supporting materials. The pretreatment of CM, selection of optimal parameters, Co‐AD of CM with other substrates, and addition of supporting materials overall enhance biogas and methane production due to increase of hydrolysis and C/N and decrease of ammonia inhibition, CO2 and H2S contents. The implementation of developed control strategies in continuous plants, development of new strategies, and use of supporting materials in combinations of two or three for better performance are the future challenges in the AD of CM. The control strategies had a significant impact on the efficient use of CM and improved biogas and methane production.
