Circular Economy Adoption in Construction Requires Enhanced Information Exchange and Stakeholder Collaboration

Why It Matters

The construction sector is a major consumer of resources and a significant generator of waste. Implementing circular economy strategies is crucial for environmental sustainability. This research highlights that effective information exchange and collaborative efforts are foundational to overcoming current linear economic models and realizing the benefits of circularity.

Key Finding

The study found that the construction industry has not fully explored circular economy applications, suffers from a knowledge gap regarding its benefits, and faces challenges due to poor stakeholder collaboration in information sharing and processes. A fundamental shift in strategies across all involved parties is necessary for a successful transition.

Key Findings

• Existing research on the application of circular economy by construction companies is not fully explored.
• There is a lack of knowledge about circular economy and its benefits within the industry.
• Poor collaboration exists between stakeholders, impacting information sharing and processes.
• All stakeholders need to change their strategies for a successful transition to a circular economy.

Research Evidence

Aim: To investigate circular economy strategies in the construction and manufacturing industries and identify how digital technology can support these strategies, while also exploring industry perspectives on potential research gaps.

Method: Scoping literature review and expert interviews

Procedure: A scoping literature review of 117 articles was conducted, analyzing the frequency and application of the 11Rs framework for circular economy. Seven interviews with Swedish experts were then performed to gather industry insights and identify research gaps.

Sample Size: 117 articles (literature review), 7 experts (interviews)

Context: Construction and manufacturing industries, with a focus on circular economy principles.

Design Principle

Information transparency and collaborative ecosystems are critical enablers for sustainable design and production.

How to Apply

When designing products or systems, proactively engage with supply chain partners and end-of-life stakeholders to establish clear communication channels for material flow, reuse, and recycling information.

Limitations

The study focused on Swedish experts, potentially limiting the generalizability of industry perspectives to other regions. The literature review scope might not encompass all relevant research.

Student Guide (IB Design Technology)

Simple Explanation: To make things more sustainable (like building houses or making products), we need to share information better and work together more. Many people don't know enough about how to reuse materials, and companies don't talk to each other enough.

Why This Matters: Understanding how information exchange and collaboration impact sustainability is vital for designing products and systems that are truly circular and minimize environmental impact.

Critical Thinking: To what extent can digital technologies truly bridge the information gap and foster collaboration if the underlying organizational cultures and business models remain resistant to change?

IA-Ready Paragraph: This research highlights that the successful implementation of circular economy principles within industries like construction is significantly impeded by inadequate information exchange and a lack of collaborative efforts among stakeholders. The study emphasizes that a widespread knowledge gap regarding circular economy benefits and practices, coupled with poor inter-company communication, necessitates a fundamental shift in strategic approaches across all involved parties to achieve a truly circular system.

Project Tips

• When researching a design problem, consider the flow of information between different industries or user groups.
• Investigate how a lack of communication might be hindering a more sustainable outcome for your design.

How to Use in IA

• Reference this study when discussing the importance of stakeholder engagement and information sharing in achieving sustainable design goals, particularly in sectors like construction.

Examiner Tips

• Demonstrate an understanding of the systemic challenges in adopting sustainable practices, such as the need for inter-industry collaboration and knowledge dissemination.

Independent Variable: ["Information exchange between construction and manufacturing industries","Stakeholder collaboration"]

Dependent Variable: ["Adoption of circular economy strategies","Reduction of waste and resource consumption"]

Strengths

• Combines a broad literature review with specific industry expert interviews for a comprehensive perspective.
• Addresses a critical and timely issue of sustainability in major industries.

Critical Questions

• How can design processes be adapted to proactively incorporate and facilitate the necessary information exchange for circularity?
• What specific digital tools or platforms are most effective in overcoming existing barriers to collaboration in these sectors?

Extended Essay Application

• An Extended Essay could explore the development of a prototype digital platform designed to facilitate information exchange for circular economy practices between construction material suppliers and demolition companies.
