Developing a reverse supply chain (RSC) model for construction and demolition waste (CDW) can improve recycling rates and reduce environmental impact. This study presents a conceptual model to guide future research and policy for CDW management.
Area of Science:
- Environmental Science
- Supply Chain Management
- Waste Management
Background:
- Construction and demolition waste (CDW) poses significant environmental challenges due to high generation volumes and low recycling rates.
- Current recycling facilities are often not integrated into specific reverse supply chains (RSC) for CDW, leading to prohibitive recovery costs.
- The lack of continuous processing capacity hinders efficient CDW management.
Purpose of the Study:
- To systematically analyze existing literature on CDW management and reverse logistics.
- To develop a conceptual RSC model tailored for construction and demolition waste.
- To provide clarity on CDW reverse logistics and stimulate academic and policy discourse.
Main Methods:
- A qualitative systematic literature analysis was conducted using a mixed-philosophies epistemological design (interpretivism and constructivism).
- A conceptual model (CM) was developed and represented as a process diagram.
- The CM was structured into three swim lanes (distribution, manufacturing, sourcing and warehousing) incorporating stakeholders, government strategies, and activity flow paths.
Main Results:
- A novel conceptual model for a construction and demolition waste reverse supply chain was developed.
- The model delineates processes and incorporates key actors, government strategies, and activity flows.
- The research provides a framework for understanding and managing CDW within an RSC context.
Conclusions:
- The proposed conceptual model offers practical and theoretical contributions to CDW management and reverse logistics.
- This work aims to demystify reverse logistics for CDW, aiding policymakers in developing effective environmental strategies.
- Further research is encouraged to build upon this model for reduced environmental impact from construction activities.
