Abstract: The amount of waste polyethene plastic waste materials have increased in the resent years and the management and disposal method to cub its attendant environmental effect is a challenging problem. Predominantly, recycling of this polyethene plastic waste is very low because the processes of recycling are not economical. The present ways of reclaiming and disposing poyethene pastic waste is by incineration which is unsustainable because of its hazardous effect in our environment. Hence, the need to adopt sustainable approach to effectively manage this waste is of utmost importance. This research presents a sustainable alternative engineering management approach to tackle the degradation consequences of polyethene plastic waste. This was done by utilizing the polyethene plastic waste as a civil engineering material for soil improvement and stabilization processes. The stabilization was carried out experimentally by conducting liquid and plastic limits test, compaction and triaxial compression test. Different percentage by weight of shredded polyethene plastic waste (0, 2, 3 and 4%) of 2 different aspect ratios was mixed with clay soil. The result obtained reveals that the strength parameters (shear strength, angle of internal friction and reduction in the optimum moisture content and maximum dry density) of the soil were increased. Hence, using polyethene plastic waste for soil stabilization and improvement is a sustainable approach in plastic waste management system.
