Circular economy in construction materials production: Current status, potential and implementation solutions

Abstract

The depletion of natural resources, environmental pollution, and climate change necessitate a transition from the linear economic model to the circular economy (CE) model. The construction materials industry is among the sectors with high resource consumption and greenhouse gas emissions. This paper synthesizes investigation, survey, and analytical results to assess the current situation and potential for CE implementation across sub-sectors of Vietnam’s construction materials industry (including cement, ceramics, construction glass, tiles, fired bricks, and unfired bricks). It further proposes appropriate solutions and a roadmap aligned with the national context. The research findings indicate that: (i) the construction materials industry has substantial potential for utilizing various types of industrial waste as alternative raw materials and fuels; (ii) the adoption of CE can reduce CO₂ emissions, conserve resources, and lower waste treatment costs; however, (iii) there remain significant technical, legal, and market barriers. Based on these findings, the paper proposes an integrated set of policy, technological, managerial, and financial measures, along with a three-phase roadmap (2025–2030: pilot phase; 2030–2040: expansion; 2040–2050: integration and optimization). Specific recommendations are provided to facilitate the practical implementation of the circular economy in Vietnam’s construction materials production sector, contributing to the achievement of sustainable development goals and national emission reduction commitments.
