“…Anaerobic digestion is currently a well-established technology in Europe with large-scale systems developed primarily in countries such as Germany and Denmark [1][2][3]. Nevertheless, studies need to be initiated to improve current technologies and encourage the use of biogas [4][5][6][7]. Anaerobic co-digestion is defined as a treatment that combines different types of wastes with the aim of increasing biogas yields.…”

Anaerobic co-digestion involves the treatment of different substrates with the aim of improving the production of biogas and the stability of the process. In this research, co-digestion of swine manure (SM) and energy crop residues (ECRs) was studied. The mixtures evaluated contained SM combined with maize (Mz), rapeseed (Rs) or sunflower (Sf) residues. Batch and semi-continuous experiments were performed to determine methane (CH 4 ) yields and the behavior of reactors while co-digesting agricultural wastes. Three different proportions of ECRs were tested in batch experiments for co-digestion with SM: 25, 50, and 75% volatile solids (VS). On the basis of the results obtained from batch tests, a mixture with a 50% ECR content was selected for the second stage of the study. Mesophilic reactors with a 3 L working volume were used for semicontinuous experiments. The hydraulic retention time (HRT) was set at 30 days and the reactors were kept under these operational conditions over four HRTs. The addition of ECR to the co-digestion system resulted in a major increase in the amount of biogas produced daily. The highest biogas yield was obtained when co-digesting Rs (3.5 L/day), although no improvement was observed in specific gas production from the addition of the co-substrate.

“…Researchers have attempted to optimise the feed composition for anaerobic digestion by mixing different wastes together in different combinations. The optimisation process is mainly aimed at improving the methane generation potential from different mixtures [7][8][9][10][11]. Statistical methods are also used to study the response surface analysis for the various waste combinations used in the study [9].…”
