01

Key Findings

01Fifteen construction and demolition waste management issues were identified for the construction and renovation stage, along with corresponding strategies.
02Eight construction and demolition waste management issues were identified for the use and operate stage, along with corresponding strategies.
03Circular economy strategies like modular design and material reuse can optimize project timelines, costs, and quality.

02

Application

Design takeaway

Integrate circular economy principles, such as modular design and material reuse, into the early design and operational planning of construction projects to minimize waste and enhance resource efficiency.

How to apply

When designing a new building or planning a renovation, actively seek opportunities to specify modular components and identify materials that can be salvaged and reused. Develop operational plans that include detailed waste segregation and recycling protocols.

Project actions

01When researching materials, look for options that are recyclable or can be easily salvaged.
02Consider how your design might be adapted or deconstructed in the future.

Method & Evidence

AimWhat are the key challenges and effective circular economy strategies for managing construction and demolition waste during the construction, renovation, and operation phases of buildings in Sri Lanka?

MethodQualitative research using the Delphi technique

ProcedureThree rounds of expert interviews were conducted to identify waste management issues and corresponding circular economy strategies for different building lifecycle stages. Data was analyzed using manual content analysis.

SampleUp to 17 experts

ContextConstruction industry in Sri Lanka, focusing on building construction, renovation, and operation.

Variables

IVImplementation of Circular Economy strategies (e.g., modular design, material reuse)

DVConstruction and Demolition Waste Generation, Resource Utilization Efficiency, Project Timeline, Project Cost, Project Quality

CVBuilding lifecycle stage (construction, renovation, operation), Geographic location (Sri Lanka)

04

Strengths & Limitations

Strengths

+Focuses on critical stages of the building lifecycle.
+Employs a structured expert consensus method (Delphi technique).

Limitations

The availability of specific circular economy strategies and materials may vary depending on local resources and regulations.

Reliability & validity

The Delphi technique aims to achieve expert consensus, enhancing the validity of findings. However, the qualitative nature and specific context may limit generalizability and require further quantitative validation.

Think critically

How might the cultural context or economic conditions of a region influence the successful implementation of circular economy strategies in construction?

05

Design Principles

"Design for Disassembly and Reuse: Plan for the end-of-life of building components by designing for easy deconstruction and maximizing the potential for material reuse."

This research highlights actionable strategies for managing construction and demolition waste, a major environmental concern. By focusing on circularity, design and construction professionals can move towards more sustainable practices, impacting project timelines, costs, and overall environmental footprint.

06

What This Means for Your Design

This study shows that by thinking about how to reuse materials and build in sections that can be easily taken apart, construction projects can create much less waste and be more efficient.

How to use in your project

1.Reference this study when discussing the environmental impact of construction materials and methods.
2.Use the identified strategies as potential solutions for waste reduction in your own design project.
