Analysis of physicochemical characteristics of municipal solid waste in Hung Yen city

Abstract

Socioeconomic development enhances the quality of human living; however, it also brings environmental problems and risks, especially municipal solid waste (MSW) issues. In order to choose a suitable MSW treatment solution for local conditions in the context of the circular economy, the group of authors have collected solid waste samples from urban and suburban locals in Hung Yen city, Hung Yen province. The solid waste samples were classified for physical composition and the calorific value, ash, and chemical element composition were measured. The research results
suggested that the solid waste incineration method with energy recovery can be applied in Hung Yen city because the combustible content in the MSW is relatively high at about 60% and the calorific values range from 17,244 to 19,427 kJ/kg, respectively. Moreover, because of the high composition of food waste, as well as a low sulfur (S) content (about 0.1%) and a carbon-to-nitrogen (C/N) ratio between 20:1-25:1, composting should be selected for the treatment of solid waste to adopt a green economy. The results obtained from this study would be a useful database
that helps managers select treatment methods appropriate to local socioeconomic conditions.
