TL;DR: The results show that thermal pretreatment at 175 °C/60 min significantly decreases viscosity, improves the MBW dewatering performance, as well as increases soluble chemical oxygen demand, soluble sugar, soluble protein, and especially organic compounds with molecular weights >10 kDa.

TL;DR: In this paper, a pilot-scale anaerobic co-digestion research study is presented to elucidate the feasibility of developing an aerobic digestion (AD) as an effective disposal method for municipal biomass waste (MBW) in China, focusing on biogas production and greenhouse gas (GHG) reduction.

TL;DR: By monitoring the biogas production rate (BPR), the anaerobic digestion system has a higher acidification risk under an OLR of 8.0 kg VS (m(3)d)(-1), which remarks the possibility of relating bioreactor performance with BPR in order to better understand and monitor anaerobia digestion process.

TL;DR: Co-digestion of wasted sewage sludge, restaurant kitchen waste, and fruit-vegetable waste was carried out in a pilot plant with thermal hydrolysis pre-treatment, and it was found digestibility increased by 115% and energy cost can be partly balanced by decreasing viscosity and improving dewaterability of the digestate.

TL;DR: The results show that the methanogenesis process was inhibited by the accumulated volatile fatty acids when 30% of dewatered activated sludge (DAS) was co-digested with food waste (FW) and fruit/vegetable residue (FVR) at high OLR.
