A Comprehensive Review of the Key Factors Affecting Biogas Production From Anaerobic Digestion of Organic Waste

CleanMat, Volume 3, Issue 2, Page 74-98, June 2026.
Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

Waste to Bioplastic Conversion by the Moderate Halophilic Bacterium Halomonas Boliviensis

Chemical Engineering Transactions, 2016
The main purpose of this work was to evaluate the use of a waste stream for the production of polyhydroxyalkanoates (PHA). With the anaerobic acidogenesis process it is possible to treat and revaluate complex waste into a wide combination of volatile ...

Spatial monitoring of hydrolysis in a plug-flow bioreactor: a support for flexible operation?

Bioresources and Bioprocessing
Hydrolysis at changing hydraulic retention time, recirculation, bedding straw content in the feed, bioaugmentation and the impact of those changes on gradient formation in the liquid phase in plug-flow reactors (PFRs) was examined.

Methane emissions from fresh dairy cattle and pig slurry

Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Role of extracellular cues to trigger the metabolic phase shifting from acidogenesis to solventogenesis in Clostridium acetobutylicum

, 2013
Clostridium acetobutylicum exhibits a two-step metabolic pathway where substrates are first converted to organic acids accompanied by a decrease in pH. The acids are then assimilated to organic solvents.

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...
