The disposal of industrial waste can cause negative environmental side effects, including greenhouse gas emissions. This study evaluated the dry anaerobic digestion (AD) of BSG for bioenergy recovery as a solution toward a more sustainable brewery. The laboratory-scale agitated tank batch reactor (6.8 L) was started up with BSG (25%), mesophilic inoculum (45%), and water (30%). The experimental results showed 82.12% solids biodegradation, 57.38% soluble chemical oxygen demand removal, and an accumulated methane yield of 10.53 L CH4 kg\u22121 TVS. The methane production efficiency was evaluated by the modified Gompertz, Cone, and first-order kinetic models. The Cone model fitted methane evolution better than the modified Gompertz and first-order kinetic models. The biogas produced from the dry AD of BSG could generate electricity (0.133 MWh ton\u22121) and heat (598.45 MJ ton\u22121), mitigating 0.0099 and 0.0335 tCO2eq ton\u22121 BSG, respectively, for electricity and heat. The implementation of dry AD could supply 7.38% of the electricity and 6.86% of the heat required for beer production. Finally, in a biorefinery concept, dry AD can be an alternative route for solid waste management and bioenergy recovery, contributing to reduce the environmental impact of breweries.<\/jats:p>","DOI":"10.3390\/fermentation9010002","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T03:56:08Z","timestamp":1671508568000},"page":"2","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Dry Anaerobic Digestion of Brewer\u2019s Spent Grains toward a More Sustainable Brewery: Operational Performance, Kinetic Analysis, and Bioenergy Potential"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1780-2160","authenticated-orcid":false,"given":"William Gustavo","family":"Sganzerla","sequence":"first","affiliation":[{"name":"School of Food Engineering (FEA), University of Campinas (UNICAMP), Monteiro Lobato St., 80, Campinas 13083-862, SP, Brazil"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7097-1342","authenticated-orcid":false,"given":"Josiel Martins","family":"Costa","sequence":"additional","affiliation":[{"name":"School of Food Engineering (FEA), University of Campinas (UNICAMP), Monteiro Lobato St., 80, Campinas 13083-862, SP, Brazil"}]},{"given":"Miriam","family":"Tena-Villares","sequence":"additional","affiliation":[{"name":"Faculty of Marine and Environmental Sciences (CASEM), University of Cadiz, Pol.
