| Abstract |
Anaerobic digestion is a well-established technology for energy production and to diminish the environmental impact of different types of organic residues, which are mainly produced from human activities (processing food) but also from other recent activities related to energy generation processes (biofuel production). In the present study, mango organic residues: mango peel (MP) and mango seed (MS), and microalgal residue biomass (MRB) were co-digested in different proportions using a mixture design. The optimized mixture proportions of 60:20:20% of MP, MS and MRB, respectively, were determined by applying the simplex-centroid method to reach the highest biochemical methane potential (BMP); additionally, the mixture with the lowest BMP was selected (40:20:40%). The effects of thermal, physical and biological pretreatments of the selected mixtures were evaluated in order to improve its BMP. However, any pretreatment showed an improvement for the mixture 60:20:20, whereas the mixture 40:20:40 achieved an increment of 160.1, 72.5 and 96.4%, when the substrates were pretreated by thermal, physical and biological, respectively. The mixture optimization of these substrates shows an alternative way to reduce the environmental impact, due to their potential use in co-digestion process for biogas production.
