“…Thus, the anaerobic co-digestion of both substrates is economically feasible and practical. So far there have been numerous publications on the use of sewage sludge as a substrate in the AD process and the number of these reports is systematically growing [29,44]. However, there have been few reports on the use of confectionery waste despite its high potential [16].…”

The objective of this study was to verify the effect of kraft lignin as a microbial carrier on biogas/methane yield. An anaerobic co-digestion test process was carried out, in which confectionery waste was used with sewage sludge. At the first stage of the study pure lignin and lignin combined with polyvinylpyrrolidone (PVP) were subjected to an extensive physicochemical analysis. Their morphology, dispersion and adsorption properties were determined. The two materials were also subjected to thermal, spectroscopic and elementary analysis. The anaerobic digestion of the two substrates was carried out with and without the addition of the carrier, under mesophilic conditions and in periodic operation. The monitoring and analysis of the two essential parameters, i.e., pH and volatile fatty acids/total alkalinity (VFA/TA) ratio, revealed that the process was stable in both tests. Microbial and biochemical analyses showed intensified proliferation of eubacteria and increased dehydrogenase activity in samples prepared with the lignin + PVP material. The cell count increased by 46% in the stuffed wafers (WAF) + sewage sludge (SS) variant with the carrier, whereas the enzyme activity increased by 43%. Cell immobilisation noticeably improved the process efficiency. The biogas production increased from 722 m3 Mg−1 VS to 850 m3 Mg−1 VS (VS – volatile solids), whereas the methane production increased from 428 m3 Mg−1 VS to 503 m3 Mg−1 VS (by about 18%). The research proved that lignin could be used as a very effective microbial carrier in anaerobic digestion (AD).

“…Seemingly, as per Zhang and the writers, lime content was effective in reducing the VS content leading to raised methane amount. (Zhang J., et al, 2017). Applying Ca(OH)2 pretreatment on the sugarcane bagasse had an identical result.…”

“…105 They obtained the highest yields of CH 4 and H 2 , which were 64.8 mL g −1 -VS and 432.3 mL g −1 -VS, respectively. Zhang et al 106 evaluated the role of sewage sludge and lime mud in AD system, and concluded that lime mud was beneficial to animal colloid hydrolysis, promoted various microorganisms to degrade organic compounds, and significantly improved the bioavailability of sewage sludge. Zhang et al 107 determined the ability of lime mud to release trace elements (such as…”

Anaerobic digestion is a technology that converts complex organic matter into another form of matter, from which energy can be more easily extracted. The stability and digestion of anaerobic co-digestion with multiple raw materials as substrates is better than the performance of anaerobic mono-digestion. In the past two decades, there has been a large amount of literature on how to improve the performance of methane production in the anaerobic co-digestion process, but few systematic reviews have been conducted. This paper summarizes the factors affecting the development of anaerobic co-digestion. The process parameters, substrate optimization strategy, microbial community, and model application for improving anaerobic co-digestion performance were systematically analyzed. Methane purification technology and policies to support digestion projects are also discussed. At present, the technological process is basically mature, but the interaction between various parameters can be studied in depth. Methane purification technology expands the market for the biogas industry and increases its economic benefits. Policy is the key to promoting process technology and the methane market.
