Abstract
With the rapid development of urbanization, more and more people are willing to improve their living conditions, thus substantial attention has been paid to residential renovation in China. As a result, large quantities of renovation waste are generated annually which seriously challenge sustainable urban development. To effectively manage renovation waste, accurate prediction of waste generation rates is a prerequisite. However, in the literature, few attempts have been made for predicting renovation waste as renovation activities vary significantly in different cases. This study offers an approach to estimate the amount of renovation waste based on the vacancy rate and renovation waste generation rates at a city level. The grey system theory was applied to predict the amount of renovation waste in Shenzhen. Results showed that the amount of renovation waste would reach 135,620 tons in 2023. The research findings can provide supportive information to relevant stakeholders for developing a renovation waste management framework.
Highlights
The real estate market in China has substantially developed due to the rapid development of urbanization
The amount of renovation waste is directly affected by the size of the renovation area, and the area of renovation is more related to marketable housing area of the commodity housing
This study investigated the renovation waste generation in Shenzhen and forecasted the future renovation waste amount based on the grey system theory
Summary
The real estate market in China has substantially developed due to the rapid development of urbanization. According to the statistics provided by the China Building Decoration Association (CBDA), the area of housing sales and the renovation output value increased very fast in recent years. The total value of residential renovation projects escalated from 1140 billion yuan (about US$ 165 billion) in 2005 to 2100 billion yuan (about US$ 305 billion) in 2010, and to 3940 billion yuan (about US$ 573 billion) in 2017 [1]. These data illustrate the increasing trend in renovation of residential buildings in China
