CONSTRUCTION AND DEMOLITION WASTE ILLEGAL DUMPING: ENVIRONMENTAL, SOCIAL AND ECONOMIC IMPACTS ASSESSMENT FOR A GROWING CITY

Abstract

Solid waste management causes a significant challenge for the developing countries, especially in Vietnam. With the rapid development of Vietnam’s economic and urbanization, the construction industry has gradually become one of pillar industries of the national economy in general and particularly Hanoi capital. While the construction industry has enjoyed continuous development, huge amounts of construction and demolition waste (CDW) being generated and dumped illegally on the vacant areas including roadsides, streets, and canals occur frequently. The consequences of improper waste management are potential alarming. With the rising concerns of waste management and global carbon concentrations, this research aims to evaluate the potential environmental impacts associated with CDW and to identify the best alternative in managing the CDW. Generally, the data are not homogeneous around the research area as the number of inhabitants is not constant nor it is the economic activity. There for if all the information is showed in thematic maps, the final waste management decisions can be made more efficiently. This study is performed with the aims of analysis on the current situation of CDW management in order to identify the environmental impacts related to CDW. Thereby, this research intended to be assessing CDW recycling potential and evaluating on the economic feasibility of the utilizing of recycled materials in the future. This paper combines the planning methodology to present the final results in thematic maps that make easier to interpret them. The results of the study would play the major role in developing a sustainable system such as assessing recycling potential, choosing appropriate treatment options, or operating solid waste management system.
