In the framework of sustainable development, there is an increasing need to assess, model, and optimize the implementation of renewable energy technologies such as the anaerobic co-digestion of different organic residues. This work studied the influence of some independent parameters on the production of biogas through anaerobic co-digestion of specific organic residues widely available in Colombia (pig manure -PM-, sewage sludge –SS–, organic fraction of municipal solid waste -OFMSW-, residues from the bottled fruit drinks industry -RBFDI-, and cocoa industry residue -CIR-). The Biochemical Methane Potential (BMP) of different mixtures was assessed through a Box-Behnken experimental design, where the parameters were: volatile solids content (0.5, 1.25 and 2 g VS), C/N ratio (25, 35 and 45), and nitrogen source (0% for only SS, 50% both residues PM and SS, and 100% if only PM). The results …
