“…As Shenzhen is one of the four first-tier cities, the vacancy rate was assumed as 22% in this study. Thus, the area of renovation can be estimated by Equation (11). Here S renovation is the area of renovation, and S sale is the marketable housing area of residential real estate.…”

“…Obviously, there is a clear lack of regulations directly focusing on renovation in China.At present, the disposal of renovation waste in China is mainly based on simple landfilling [9], which causes low recycling rate and pollution to the environment [10]. It is reported that China is the largest producer who contributes over 2 billion tons of construction and demolition waste annually [11]. However, the average recycling rate of C&D waste in most cities in China is just between 3% and 10% [12], much lower than some developed countries (e.g., 93.8% for Japan [13], 94% for the Netherlands [14]).…”

Due to the limited landfill disposal capacity and high price of land resources in developed cities (e.g., Shenzhen), it is not unusual that C&D waste is transferred to less-developed neighboring regions in China [11]. Even worse, illegal dumping may happen; waste might be discharged at unpermitted areas, such as farm lands, abandoned residential lands, borrow pits, river sides, and low-lying areas.…”

Predicting Renovation Waste Generation Based on Grey System Theory: A Case Study of Shenzhen

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.

“…However, to date, most of the C&D waste produced in China has been disposed by simple land lling or dumping, which in turn creates a potential risk that threatens the security of the ecology and sustainable development in the region [6][7][8][9]. As shown in Figure 1, the recycling rate in China was merely 9.5% in 2012, which was lower than the recycling rate of most EU countries [2]. e recycling and reuse of waste materials, such as C&D waste, waste plastics and rubber, tailing, and ladle furnace slag, has been carefully studied in the last few decades in a number of countries around the world, and techniques have been proposed for how to successfully use these materials in pavements or subgrades [10][11][12][13][14][15][16][17][18][19].…”

“…Speci cally, the demolition of 1 m 2 buildings results in 0.5-1.0 m 3 of C&D waste, and every 10 thousand m 2 construction process will produce 500-600 tons of C&D waste [1]. e average annual generation of C&D waste in China was approximately 2.36 billion tons during the period from 2003 to 2013 [2]. C&D waste is mainly composed of metal, concrete, mortars, bricks, woods, and plastic.…”

e recycling and reuse of waste materials is a topic of global concern and great international interest for those interested in sustainable development and protecting the environment. In recent decades, global production of construction and demolition waste (C&D waste) has signi cantly increased and became a worldwide problem. is research proposes to evaluate the feasibility of using aggregate from recycled C&D waste for urban road embankment applications based on the Sanhuan road construction project in eastern Xi'an. An extensive suite of laboratory and eld compaction tests were carried out to determine the physical properties and engineering characteristics of the C&D waste. e e ect of curing on the strength of the C&D waste was investigated using uncon ned compression strength (UCS), California bearing ratio (CBR), and de ection tests. e results show that the C&D waste has the characteristics of high strength and signi cant stability after simple treatment and further suggest that the use of these materials for paving urban road embankments is feasible. is study is of value for the reasonable and e ective promotion of using C&D waste recycled materials in road subgrade applications.

Recycled product certification (RPC) schemes may prove useful to ensure the desired quality and gain buyer confidence in purchasing products with recycled content (PwRC). RPCs are relatively new to the sector and have not been widely adopted. Hence, this study aims to investigate the implementation of RPC in construction projects using a multiple‐case study approach. The analysis reveals that a large proportion of respondents were unaware of these schemes. The study finds that while a majority favoured RPC application, there were significant variations in responses among stakeholder groups. Moreover, the study identifies six advantages and seven significant barriers associated with the use of RPC in the sector. This study recommends leveraging education and supportive regulation for the effective implementation of RPC. In particular, the policymakers who intend to embed RPC in procurement policies for purchasing PwRC can learn about the identified loopholes and strategies and address them accordingly.
