Synergetic Process Parameters Interaction in Solid-state Anaerobic Co-digestion

In this mesophilic solid-state anaerobic co-digestion study, interaction among process parameters were  investigated. To achieve this, four treatments were considered based on two carbon to nitrogen ratios (34 and 28). The treatments were DMCS34 РDairy manure, inoculum, and untreated corn stover with C/N ratio of 34; DMCS28 РDairy manure, inoculum, and untreated corn stover with C/N ratio of 28; DMPCS34 РDairy manure, inoculum, and washed pretreated corn stover with C/N ratio of 34; and DMPCS28 РDairy manure, inoculum, and washed pretreated corn stover with C/N ratio of 28.

Effect of Pretreatment and Agitation Frequency on Methane Yield in Solid-state Anaerobic Co-digestion of Dairy Manure and Corn Stover

Solid state anaerobic co-digestion (SSCoD) has attracted huge attention in the renewable energy industry due to the potential to solve nutrient imbalance challenge. However, SSCoD potential as biogas source is often limited except the process parameters are systematically optimized. Hence, in this study, we investigated the impact of 4%-NaOH-pretreatment and two agitation frequencies (two-day and seven-day periodic agitation), being part of the process parameters, on biogas composition and methane yield.
