Implicit Industrial Symbiosis Drives Circularity in Construction Waste
Category: Resource Management · Effect: Moderate effect · Year: 2021
The construction industry can achieve circular economy goals by fostering implicit industrial symbiosis, where waste materials like recycled concrete aggregates are integrated into new supply chains through collaborative networks.
Design Takeaway
Design projects in construction should actively seek opportunities to incorporate recycled materials by understanding and potentially enabling the implicit industrial symbiosis networks that exist.
Why It Matters
Understanding and enabling implicit industrial symbiosis is crucial for designers and engineers aiming to reduce waste and resource depletion in construction. This approach highlights the potential for economic viability in reusing materials, moving beyond simple down-cycling.
Key Finding
The research found that while industrial symbiosis is present in construction, it operates implicitly due to the complex coordination needed between different parties over time and distance. This implicit nature requires specific tools and strategies to be effectively leveraged for circular economy goals.
Key Findings
- Industrial symbiosis (IS) exists implicitly in the construction industry.
- The treatment of RCA requires collaboration across multiple actors with temporal and spatial differences.
- Agent-based modeling with GIS can effectively represent dynamic supply-demand and collaboration dynamics.
Research Evidence
Aim: To explore the potential and dynamics of industrial symbiosis for recycled concrete aggregates within the Dutch construction industry to advance circular economy principles.
Method: Agent-Based Modelling (ABM) integrated with Geographic Information Systems (GIS)
Procedure: The study simulated a concrete waste supply chain in the Twente region, modeling supply chain actors as negotiable agents to analyze the dynamic supply-demand of recycled concrete aggregates (RCA) and their collaboration under various economic scenarios.
Context: Dutch construction industry, specifically focusing on recycled concrete aggregates (RCA) and their supply chain.
Design Principle
Design for material symbiosis: Integrate waste streams from one process as resources for another within a collaborative network.
How to Apply
When designing new construction projects or specifying materials, investigate local opportunities for sourcing recycled aggregates and explore potential partnerships with demolition and recycling companies.
Limitations
The study's findings are specific to the Twente region and the context of recycled concrete aggregates; generalizability to other regions or material types may vary.
Student Guide (IB Design Technology)
Simple Explanation: Even though construction companies don't always formally plan it, they can work together to reuse waste concrete as new building material, which helps the environment and can be profitable.
Why This Matters: This research shows how to make construction more sustainable by reusing waste materials, which is a key goal for many design projects focused on environmental impact.
Critical Thinking: How can designers proactively facilitate the 'implicit' industrial symbiosis identified in this study, rather than relying on it to emerge organically?
IA-Ready Paragraph: This research highlights the potential for implicit industrial symbiosis within the construction sector, demonstrating that waste materials like recycled concrete aggregates can be effectively integrated into new supply chains. By fostering collaboration between various actors, even across temporal and spatial divides, circular economy principles can be advanced. This approach offers a pathway to enhance resource efficiency and reduce the environmental footprint of construction projects.
