Study on the effect of soil properties in the presence of plastic waste

Abstract

This study investigates the impact of plastic waste on the properties of soil, focusing on its effects on physical and chemical characteristics. With the increasing accumulation of plastic waste in landfills, its interaction with soil has become a significant concern for environmental and engineering practices. The research aims to conduct a comparative analysis of soil samples with varying concentrations of plastic waste, evaluating changes in parameters such as permeability, compaction, strength, water retention, levels. Laboratory tests, including Atterberg limits, Proctor compaction, Permeability tests, specific gravity test, moisture content, particle size distribution, ph., EC, Organic matter and un- confined compressive strength test were performed on soil mixed with different types and quantities of plastic materials (e.g., polyethylene, polypropylene). The findings reveal that the incorporation of plastic waste leads to altered soil behavior, which may either improve or degrade soil properties depending on the type of plastic and its concentration. This study provides essential insights into how plastic waste impacts soil's physical stability, offering potential implications for soil stabilization techniques, soil remediation methods, and sustainable engineering practices.
