Special Issue Information

Dear Colleagues,

Sustainability is a critical focus across the construction and building industries as global efforts intensify to protect natural resources, reduce carbon emissions, and mitigate passive environmental impacts to enhance efficiency. The materials used for construction and building infrastructure play a significant impact on the environment, accounting for a substantial portion of resource consumption, energy use and greenhouse gas emissions. Life Cycle Assessment (LCA) is a valuable tool that allows for a comprehensive evaluation of the environmental impacts associated with construction and building materials throughout their entire life cycle, including raw material extraction, manufacturing, transportation, construction, use and disposal.

This Special Issue will also bring together techniques and concepts from various distinct works, examine, explore, and critically engage with sustainable construction and building materials and the detailed examination concept of LCA. The Special Issue will also support innovative approaches, methodologies, and technologies to bridge the gap and foster knowledge exchange and collaboration among researchers, practitioners, and foster energy efficiency, waste reduction, and green practices. The papers collected in this Special Issue can help researchers and practicing engineers, construction and building material scientists, low carbon and sustainability practitioners to find more advanced techniques and alternative approaches towards sustainable construction and building material development.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The increasing amount of recycled plastic waste and the extensive use of construction materials both contribute significantly to CO2 emissions, a major global concern. This study investigates the use of recycled plastic waste (PW) as a partial replacement for natural 4/10 mm coarse aggregates in concrete mix design, aiming to promote sustainable construction practices. Concrete mixes were prepared with varying levels of plastic replacement—0%, 15%, 30%, 45%, and 60% by volume—and evaluated for workability, compressive strength, tensile strength, water absorption, and microstructural properties. Results indicated that replacing aggregates with PW increased slump values, suggesting improved workability, particularly at 30–45% replacement. However, both compressive and tensile strengths exhibited a declining trend as the replacement level increased. The standard strength was maintained only at 15% replacement, achieving 35.3 MPa at 56 days compared to 37.3 MPa for the control mix. Durability tests showed reduced water absorption at low replacement levels but significant porosity and microcracking at higher percentages. Scanning Electron Microscopy (SEM) revealed weak interfacial transition zones (ITZs) between plastic waste and cement paste, with bonding weakening and micro voids increasing as replacement levels rose. A simplified life cycle assessment (LCA) suggests that while CO2 emissions remain largely unchanged due to cement dominance, incorporating recycled plastic waste provides sustainability benefits through resource conservation and waste diversion rather than direct carbon reduction. These findings highlight that limited aggregate replacement with plastic waste can be practical, cost-efficient, and environmentally advantageous. This research underscores the potential of recycled plastics in sustainable construction, contributing to waste management and reducing reliance on natural aggregates. Full article
