摘要: In this paper, performance analysis over two years’ operation of an industrial anaerobic digestion (AD) plant a separately collected organic fraction municipal solid waste is presented. The continuous plug-flow AD still regularly operating and it has been fully operational since September 2018. Since then, supplied with 40,000 t/y pretreated from municipalities the Calabria region in Southern Italy. process carried out mesophilic regime at 40 ± 0.5 °C, using constant hydraulic retention time (HRT) 22 days substrate average total solids volatile 30.0% 22.2%, respectively. last years, produced 191 m3 860 biogas per tonne (t) input material solids, respectively, methane specific production 508 m3/t (total solids). CH4 percentage was 59.09%. obtained results came combination high content waste, optimized pretreatment system conditions adopted.
