“…Until recently, various biomass wastes such as crop waste , forestry waste (Zheng et al, 2015), fruit waste (Dias et al, 2014), vegetable waste (Belle et al, 2015), food waste (Zarkadas et al, 2015;El-Mashad and Zhang, 2010), and municipal solid wastes (Macias-Corral et al, 2008) have been used to perform a anaerobic co-digestion with DM. The codigestion of DM with three crop straw residues (SRs) under five mass mixing ratios (SRs/DM) demonstrated that a high methane content and the highest cumulative biogas yield were achieved at the SRs/DM mass mixing ratios 1:9 and ratio 5:5, respectively .…”
