The aim of this paper is to assess the current situation of solid waste generation and forecast the amount of domestic solid waste in Cao Bang city, Cao Bang province in Vietnam by 2035. The study used a number of main research methods such as collecting primary and secondary data, actual investigation methods, using mathematical formulas to calculate and process data to get the results. The results show that the source of domestic solid waste in Cao Bang city is very diverse, mainly from urban areas, accounting for 93.09%. Emission coefficient in urban area is 1.13 kg/person/day and in rural area is 0.51 kg/person/day. Domestic solid waste composition is mainly organic solid waste (58.17%) while non-recyclable solid waste accounts for the lowest rate (7.2%).
