The total generation of household, commercial and manufacturing waste in Ulaanbaatar exceeds 1 million t/y. Updated figures show practically the same waste generation from ger districts in summer and winter, because a lot of waste generated by ger residents in winter is used as fuel. In contrast, analysis of monthly data in 2013-2014 shows peaks of waste generation during the summer months, w'hich is attributed to commercial activities, mainly construction activities and services.
