Plastic Bottles Filled with Fully Saturated On-Site Soil Material for Slope Stabilization
AI summary Read the abstract
Researchers investigated the feasibility of using plastic bottles filled with fully saturated on-site soil as a low-cost, waste-reducing method for slope stabilization, evaluating the material preparation, mechanical performance, and environmental benefits of this approach. The study found the technique offers a promising dual benefit of addressing plastic waste while providing effective, cost-efficient erosion control.
This study focuses on the feasibility of employing plastic bottles filled with fully saturated on-site soil for sustainable slope stabilization. Also, this research explores material preparation, mechanical performance, and environmental benefits addressing the global plastic waste crisis and the need for cost-effective erosion control. To ensure a robust testing framework, soil assessment, collection, and saturation procedures were standardized. Correspondingly aligned to ASTM D695 for compressive strength tests the structural integrity of the soil-filled bottles, and ASTM D792 for density assessments to validate soil compaction. Field implementation was carried out on erosion-prone slopes in the Province of Antique involving strategically arranging and securing the bottles. Compared to conventional methods, results prove that the innovative method can provide sufficient structural support at a substantial cost reduction of 92.89%. This study aligns with the UN Sustainable Development Goal 9 which demonstrates the potential of repurposing plastic waste into a sustainable and economically viable alternative for slope protection. Thus, in managing steep terrain, preventing erosion, and promoting environmental sustainability in resource-limited settings; this innovative approach offers a practical solution. To explore long-term durability, material variability, and potential microplastic leaching, further research is recommended.
