Overview of pretreatment strategies for enhancing sewage sludge disintegration and subsequent anaerobic digestion: Current advances, full-scale application and future perspectives
TL;DR: In this article, an up-to-date review of recent research achievements in the pretreatment technologies used for improving biogas production including mechanical (ultrasonic, microwave, electrokinetic and high-pressure homogenization), thermal, chemical (acidic, alkali, ozonation, Fenton and Fe(II)-activated persulfate oxidation), and biological options (temperature-phased anaerobic digestion and microbial electrolysis cell).
Journal ArticleDOI
Investigation into the effect of high concentrations of volatile fatty acids in anaerobic digestion on methanogenic communities.
TL;DR: Different methanogenic communities in mesophilic and thermophilic reactors do not cause major changes in archaeal communities, and real-time PCR indicated greater diversity than ANAEROCHIP microarray.
Journal ArticleDOI
An overview of biogas production and utilization at full-scale wastewater treatment plants (WWTPs) in the United States: Challenges and opportunities towards energy-neutral WWTPs
TL;DR: In this paper, the barriers, gaps, and challenges in deploying biogas production technology are identified, and the issues are classified as economic, technical, social or regulatory issues.

Microbial characteristics in anaerobic digestion process of food waste for methane production–A review
TL;DR: A critical summary of microbial characteristics was provided to obtain connects of microbial community structure with operational conditions at various states of AD, such as mesophilic and thermophilic, wet and dry, success and failure, pretreated or not, lab-scale and full-scale.
Journal ArticleDOI
The challenges of anaerobic digestion and the role of biochar in optimizing anaerobic digestion
Michael O. Fagbohungbe,Ben M.J. Herbert,Lois Hurst,C. N. Ibeto,Hong Li,Shams Qamar Usmani,Kirk T. Semple +6 more
TL;DR: This review will examine substrate inhibition and their impact on anaerobic digestion, nutrient leaching and their environmental implications, the properties and functionality of biochar material in counteracting these challenges.

Inhibition of anaerobic digestion process: A review
TL;DR: This review provides a detailed summary of the research conducted on the inhibition of anaerobic processes and indicates that co-digestion with other waste, adaptation of microorganisms to inhibitory substances, and incorporation of methods to remove or counteract toxicants before an aerobic digestion can significantly improve the waste treatment efficiency.

Anaerobic digestion of swine manure: Inhibition by ammonia
TL;DR: A stable anaerobic degradation of swine manure with ammonia concentration of 6 g-N/litre was obtained in continuously stirred tank reactors with a hydraulic retention time of 15 days, at four different temperatures as discussed by the authors.
Journal ArticleDOI
Thermophilic anaerobic digestion of livestock waste: the effect of ammonia
TL;DR: A stable digestion of cattle manure could be maintained with ammonia concentrations up to 6 g N/l after 6 months of operation, however, the methane yield was reduced and the concentration of volatile fatty acids increased from 1 to 3 g/l as acetate, compared to controls with an ammonia concentration of 2.5 gN/l.

Brian P. Kelleher,James J. Leahy,Anne Marie Henihan,T. F. O’Dwyer,David Sutton,Martin J. Leahy +5 more
TL;DR: A review of advances in the three main alternative disposal routes for poultry litter, specifically in the last decade, is presented in this paper, where results of experimental investigations into the optimisation of composting, anaerobic digestion and direct combustion are summarised.
