TL;DR: The technology of anaerobic digestion of organic solid wastes is, in many aspects, mature and its relation to composting technology is examined in this review.

TL;DR: A review of codigestion practices starting from the late 1970s, when the first papers related to this concept were published, and continuing to the present day, demonstrating the exponential growth in the interest shown in this approach in recent years.
Abstract: The last two years have witnessed a dramatic increase in the number of papers published on the subject of codigestion, highlighting the relevance of this topic within anaerobic digestion research. Consequently, it seems appropriate to undertake a review of codigestion practices starting from the late 1970s, when the first papers related to this concept were published, and continuing to the present day, demonstrating the exponential growth in the interest shown in this approach in recent years. Following a general analysis of the situation, state-of-the-art codigestion is described, focusing on the two most important areas as regards publication: codigestion involving sewage sludge and the organic fraction of municipal solid waste (including a review of the secondary advantages for wastewater treatment plant related to biological nutrient removal), and codigestion in the agricultural sector, that is, including agricultural – farm wastes, and energy crops. Within these areas, a large number of oversized dig...

TL;DR: The digestate stability, evaluated through a respirometric assay, showed that co-substrate addition does not exert a negative impact on digestate quality and the analysis of the macro-compounds showed lower removal efficiencies in the co-digester as the microorganisms obtained nutrients from the soluble carbohydrates provided by the glycerol.

TL;DR: Kinetics improvement was linked to the mitigation of inhibitory compounds, particularly fats dilution, and the exception was co-digestion of paunch with lipids, which resulted in an improved final yield with model based analysis indicating the presence of pauncy improved degradability of the fatty feed.

TL;DR: The anaerobic digestion model is a reliable tool for the design and operation of plants in which agro-wastes are treated and concluded that the correlation between the model and the experimental results was satisfactory.

TL;DR: In this paper, the authors present a review of the current status of the hydrothermal liquefaction of biomass with the aim of describing the current state of the technology, which is a medium-temperature, high-pressure thermochemical process which produces a liquid product, often called bio-oil or bi-crude.

TL;DR: The ability of these CO2 consuming microalgae to purify biogas and concentrate methane is discussed, and anaerobic digestion of the whole biomass appears to be the optimal strategy on an energy balance basis for the energetic recovery of cell biomass.
1,153 citations
TL;DR: Ammonia inhibition in anaerobic digestion systems and the recovery efforts after inhibition are discussed and the impacts of ammonia inhibition on the microbial population available in an aerobic digesters, namely bacteria and Archaea are evaluated in detail.

TL;DR: Structural studies will further improve the understanding of the mechanism of action of these enzymes and aid in improving and selecting better candidates for increased production of poly(3-hydroxybutyrate) (PHB) production.
