Abstract Construction and demolition waste (CDW) is a growing waste stream in the world. The implementation of the circular economy for its management requires decision-making tools based on multiple criteria to identify the most appropriate location for a CDW recycling facility. However, technical, economic, and social criteria …
Therefore, this study aims to understand the impact of innovative technologies in construction activities on the recycling chain in China from the perspective of concrete debris, which will help to make appropriate recycling strategies in developing countries for the circular economy transition.

mental impacts. Recycling is a benecial way to dispose of CDW that reduces environ-mental impact and brings economic benets, especially for concrete. China is the country that generates the most CDW in the world, but its domestic recycling rate is much lower than that of developed countries. While the ecient technologies in developed regions
Recycling of building materials is not a novelty. Romans use construction waste like ceramic in their concrete . However, nowadays except from large natural disasters or war and in a few European countries actual recycling of mineral fraction of construction materials is often more an exception than a rule. More than that, most of …

Strategies for enhancing construction waste recycling. CWR is a common practice in several developed countries. Through CWR, several new materials can be …
Comparatively, the CDW recycling and reuse rate can reach 70%–95% in some developed countries, including the United States, Denmark, South Korea, …
This chapter will discuss the current policies and legislation for e-waste in emerging and developed countries. Asia is responsible for 46% of global e-waste generation, followed by America (24.4%), Europe (22.4%), Africa (5.4%), and Oceania (1.3%), while Europe has the highest generation per capita (30.2%) (Forti et al. 2020). …
Between 7.7 and 23.1 million tonnes of wind turbine blade waste could be generated in China by 2050, but although recycling approaches exist, they are not always available, cost-effective or ...
According to the database of the Organization for Economic Co-operation and Development (OECD) in 2015, about 36% of the total generated waste is attributed to …
Whereas, the volume of waste in the world continues to grow day by day. The aim of this study is to explore best practices of construction waste management in developed countries to be implemented in Indonesia. The objectives are; (1) to examine the implementation of waste management in construction projects in developed …
The construction industry generates many environmental pollutants, such as noise, air pollution, solid and liquid waste, water pollution, harmful gases, and dust (Adnan et al. 2014).It is classified as the world's largest consumer of raw materials, the highest energy-consuming sector, reaching up to 36% of the total energy consumption, and one …

Developing …
Construction and demolition waste (C&DW) has a deleterious impacts on sustainability not only in developing countries but also in developed nations. For example, Australia generated more than 27 million tonnes of C&DW in 2018–2019; however, only 60% of this waste stream was recovered. Considering this low recovery rate, lower than …
To create a truly circular economy requires a shift from the traditional view of waste disposal to one of resource management. This is particularly important in developing countries, where municipal waste generation is increasing, and efficient recovery of economic value from waste is rarely achieved. Conducted in the University of Lagos …
