Influence of the Use of Co-Substrates on the Anaerobic Co-Digestion of Municipal Solid Waste, Cocoa Industry Waste and Bottled Beverage Industry Waste

Colombia generates large quantities of organic waste that are not used or deposited in the correct way. Therefore, this project seeks to harness the organic load of these residues using anaerobic co-digestion, which is a biological process that allows the recovery and the biochemical potential of me...

The anaerobic co-digestion technique allows the efficient development of the process due to the synergistic behavior of the co-substrates used, which compensate for the shortcomings that each presents when performing the process separately. It is also important to mention that the mixtures that have cocoa industry waste and bottled beverage industry waste increase the biochemical potential of methane.
