We are investigating waste that can be used in co-digestion processes with sewage sludge to increase biogas production.
Anaerobic co-digestion of sludge with food waste (FW) in the context of the Biofactory.
Studying the co-digestion of sludge waste from the Gran Santiago biofactory with waste from different origins allows us to increase biogas production and generate synergies that improve the process by increasing volatile matter, which is easier for microorganisms to digest, and providing complementary nutrients to the sludge that improve stability and specific performance. Following this line of research, and after testing over 25 cosubstrates in batch mode (BPM), we have developed a co-digestion model to simulate operational variables of the biofactory, which enables effective management and planning of cosubstrates. Previously, we established a process for co-substrate evaluation in order to ensure the success of the full-scale process.
