Special Issue Information

Dear Colleagues,

The construction industry is one of the largest global consumers of raw materials and energy, generating significant environmental impacts and waste. In response, the transition to a circular economy (CE) model is essential for reducing resource depletion, minimizing waste, and promoting sustainable and resilient built environments. This Special Issue aims to explore innovative materials, construction techniques, policy frameworks, and business models that contribute to circularity in the construction sector.

This Special Issue will provide an interdisciplinary platform for discussing the latest advancements, challenges, and practical applications of circular economy principles in construction. We welcome contributions that address the following:

  • The development and integration of circular materials and bio-based composites in construction;
  • Waste valorization strategies and the reuse of demolition materials;
  • Digitalization and Industry 4.0 approaches for circular construction;
  • Policy, governance, and regulatory frameworks that foster CE adoption;
  • Socio-economic and life cycle assessments of circular construction models.

By bridging technical, economic, and policy perspectives, this Special Issue will supplement the existing literature by highlighting how circular economy strategies contribute to sustainability, resilience, and carbon footprint reduction in construction. We invite researchers and practitioners to submit high-quality original research, case studies, and review papers.

Concrete demolition waste represents a critical bottleneck in achieving a circular economy for the construction sector. This study develops a system-dynamics model that couples material flows with economic and logistical feedback to quantify how cost structures affect concrete recycling in the Sydney (Australia) metropolitan area. The model is calibrated with (i) official New South Wales 2020–2021 construction-and-demolition waste statistics, (ii) concrete consumption data scaled from state infrastructure reports, and (iii) parameters elicited from structured interviews with recycling contractors and plant operators. Scenario analysis systematically varies recycling-plant fees, landfill levies, and transport costs to trace their nonlinear impacts on three core performance metrics: recycling rate, cumulative landfill mass, and virgin gravel extraction. Results reveal distinct cost tipping points: a 10% rise in landfill-logistics costs or a 25% drop in recycling logistics costs shifts more than 95% of concrete waste into the recycling stream, cutting landfill volumes by up to 47% and reducing virgin aggregate demand by 5%. Conversely, easing landfill costs by 25% reverses these gains, driving landfill dependency above 99% and increasing gravel extraction by 39%. These findings demonstrate that carefully calibrated economic levers can override logistical inefficiencies and accelerate circular construction outcomes. The system-dynamics framework offers policymakers and industry stakeholders a decision-support tool for setting landfill levies, recycling subsidies, and infrastructure investments that jointly minimize waste and conserve natural resources.
