Developing efficient and cost-effective psychrophilic dry anaerobic digestion (PDAD) processes could contribute to solving farm-related environmental, energy, and manure management problems in cold-climate regions. This study was to increase the organic loading rate (OLR), fed to a novel psychrophilic (20°C) dry anaerobic digestion of 27% total solid dairy manure (cow feces and wheat straw) in sequence batch reactor (PDAD-SBR), by 133 to 160%. The PDAD-SBR process operated at treatment cycle length of 21days and OLR of 7.0 and 8.0g total chemical oxygen demand (TCOD) kg−1inoculumday−1 (5.2 ± 0.1 and 5.8 ± 0.0gvolatile solids (VS) kg−1inoculumday−1) for four successive cycles (84days) produced average specific methane yields (SMYs) of 147.1 ± 17.2 and 143.2 ± 11.7normalized liters (NL) CH4 kg−1 VS fed, respectively. PDAD of cow feces and wheat straw is possible with VS-based inoculum-to-substrate ratio of 1.45 at OLR of 8.0gTCODkg−1inoculumday−1. Hydrolysis was the limiting step reaction. The VS removal averaged around 57.4 ± 0.5 and 60.5 ± 5.7% at OLR 7.0 and 8.0gTCODkg−1inoculumday−1, respectively.
