TL;DR: This paper presents a review of the main sludge treatment techniques used as a pretreatment to anaerobic digestion, and it is likely that low impact pretreatment methods such as mechanical and thermal phased improve speed of degradation, while high impact methods improve both speed and extent of degradation.

TL;DR: In this paper, the most appropriate pretreatment for the main feedstocks of biogas plants is discussed, which can enhance the methane potential and/or anaerobic digestion rate, improving digester performance.

TL;DR: Liquid fraction of digestate obtained after solid-liquid separation from 11 full-scale co-digestion plants has poor biodegradability due to presence of humic substances making aerobic treatment inefficient and only physico-chemical post treatment can be proposed for organic matter removal.

TL;DR: In this article, the authors evaluated the impact of ozone pretreatment on anaerobic digestion and particularly the enhancement of biogas production in waste activated sludge treatment and found that ozone dose of 0.15 g O3/g total solids resulted in a considerable increase in the soluble COD ratio.

TL;DR: The enhanced biodegradation of slaughterhouse wastes should be attributed to an increased initial bio-availability of fatty wastes without any modification of their long chain structure which remained slowly biodegradable.
