A Review on Sustainable Bridge Construction Using Recycled Materials for Environmental Protection
AI summary Read the abstract
This review paper explores using recycled plastic and fiberglass waste (instead of sand or gravel) to help build stronger, eco-friendly bridges and roads. While this isn't a direct human health study, it matters because it points to ways of keeping non-biodegradable plastic waste out of landfills and waterways, which could reduce environmental pollution and long-term microplastic buildup in soil and water sources we rely on. Note that this paper summarizes existing research and proposes a study design rather than reporting final results.
The rapid growth of industrialization, urbanization, and technological advancement has resulted in the large-scale generation of plastic and fiber-based waste materials, creating serious environmental challenges across the world. Fiber plastics, including fiberglass and reinforced plastic materials used in industries such as automotive manufacturing, construction, aerospace, and packaging, are non-biodegradable in nature and remain in the environment for long periods without decomposition. Improper disposal of these waste materials through landfilling or open dumping leads to soil contamination, water pollution, and ecological imbalance. In addition, the continuous extraction and consumption of natural resources for construction activities have further increased environmental degradation and resource depletion. Therefore, the effective reuse and recycling of fiber plastic waste have become essential for achieving sustainable environmental protection and waste management practices. The construction industry offers significant potential for the utilization of recycled fiber plastic waste as an alternative material in concrete production and other civil engineering applications. The incorporation of recycled fiber plastics into concrete can reduce the excessive consumption of natural aggregates while simultaneously minimizing the environmental burden caused by plastic waste accumulation. Moreover, recycled fiber materials possess desirable engineering properties such as lightweight characteristics, chemical resistance, durability, and tensile strength, which can enhance the performance of construction materials when used in optimum proportions. The present study aims to investigate the feasibility of reusing recycled fiber plastic waste in concrete for sustainable construction and environmental protection. Different percentages of recycled fiber plastic material will be incorporated as a partial replacement for conventional fine aggregate, and the performance of concrete will be evaluated through various mechanical and durability tests. Parameters such as workability, compressive strength, split tensile strength, flexural strength, and water absorption will be analyzed to determine the influence of fiber plastic content on concrete behavior. The study also focuses on identifying the optimum replacement percentage that provides improved structural performance while maintaining durability characteristics. The reuse of fiber plastic waste in construction materials can significantly reduce environmental pollution, decrease landfill disposal, conserve natural resources, and promote sustainable waste management practices. Furthermore, the adoption of recycled fiber plastic materials in civil engineering applications supports the development of eco-friendly and economical construction techniques. Overall, the study is expected to contribute toward environmental protection by encouraging the effective utilization of non-biodegradable fiber plastic waste in sustainable infrastructure development.
