The state of domestic solid waste and prediction of domestic solid waste quantity until 2035 in Cao Bang city, Cao Bang province, Vietnam

Abstract

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%). The amount of generated domestic solid waste in the city is forecasted to be 32,225.42 tons/year by 2035. The research results also show that the estimated amount of domestic solid waste generation in 2035 will increase by 1.13 times compared to 2022. This result is a necessary and important scientific basis to propose solutions to improve the efficiency of domestic solid waste management in the coming time.
