Abstract
Currently, Construction and Demolition waste (C&D waste) is a worldwide issue that concerns not only the construction management level of on-site managers but also the sustainable development of construction industry. In this paper, detailed formulas are listed for calculating the costs of three typical kinds of disposal routes of C&D waste. They are Landfill Disposal, Recycling and Reuse. Using the specific formulas, the costs of new construction project in the Pearl River Delta Region of China are also estimated. The results of this study show: From 2010 to 2013, the Pearl River Delta region costs about 87.91 yuan (1US$=6.12 yuan in September 2013) for landfill disposal of 1t(tone) C&D waste, from the site collection management to landfill disposal; about 76.33 yuan for recycling of 1t C&D waste, from the site collection management to the recycling treatment;
Highlights
As one of the major fixed asset formation sectors and cornerstone industries in the national economic system of China, the building sector is undergoing rapid development
To better analyze the cost of C&D waste management, the implementation of C&D waste management in the Pearl River Delta of China that is developed in construction industry was selected as an example to conduct cost analysis on C&D waste management ways (Landfill Disposal, Recycling and Reuse), and specific formulas were given for cost calculation
To achieve economic feasibility of C&D waste minimization in the Pearl River Delta Region and maximum of ratio of savings to costs, it could be recommended: (1) Reasonable arrangement of the C&D waste disposal field, which refers to the recycling treatment site or comprehensive disposal site
Summary
As one of the major fixed asset formation sectors and cornerstone industries in the national economic system of China, the building sector is undergoing rapid development. To better analyze the cost of C&D waste management, the implementation of C&D waste management in the Pearl River Delta of China that is developed in construction industry was selected as an example to conduct cost analysis on C&D waste management ways (Landfill Disposal, Recycling and Reuse), and specific formulas were given for cost calculation. Based on these investigation and analyses, conclusions are arrived and suggestions given. The results of this study can provide supportive data and theoretical basis for the C&D waste management decision-making in rapidly developing economies, such as China, India and Brazil
