Baijiu brewing wastewater,distillers'grains and Baijiu brewing sludge are the main wastes in the Baijiu production process,with the dual characteristics of"pollution"and"resources".Under the background of"double carbon",the resource and high-value utilization of Baijiu brewing waste have become an urgent problem for Baijiu production enterprises.The physicochemical properties of Baijiu production waste and the applica-tion of anaerobic digestion technology in the recycling process of Baijiu brewing waste were described in detail.Based on the plant nutrition charac-teristics of biogas slurry and biogas residue,it was proposed to gradually build an ecological Baijiu enterprise circular economy model with Baijiu en-terprises characteristics,and form an ecological cycle industry chain of"agriculture+Baijiu making+tourism+agriculture",in order to provide theoreti-cal references for the green and sustainable development of Baijiu enterprises.
