Evaluation of Methane Production From Hydrothermally Pre-Treated Coffee Pulp and Husk for Anaerobic Co-Digestion with Cattle Manure

Short Introductive summary

The aim of this study was to evaluate methane production with pulp and husk with and without hydrothermolyzes pretreatment using as inoculum source cattle manure (CM) and granular sludge (GS) in anaerobic batch reactors fed with liquid and solid wastes from coffee and brewery processing.Given the still scarce information about the co-digestion of coffee residues (solid and liquid) with brewery wastewater in anaerobic consortia, the scientific innovation of this study was to evaluate the methane production in a comparison of the use of pulp and husk with and without hydrothermally pretreated. This has opened new perspectives regarding the synergistic effects of cellulolytic bacteria and methanogenic archaea through the fiber composition of solid wastes, bringing benefits for reducing and treating these residues, thus improving methane production.
