Plastic has become an integral part of daily life; however, its widespread use has created significant environmental challenges due to improper disposal. One effective and sustainable approach to managing plastic waste is its use in soil stabilization. This paper provides a comprehensive review of the use of waste plastic bottle fibers for reinforcing soils. It examines the effectiveness of plastic as a soil reinforcement material and suggests suitable fiber dimensions and proportions for optimal performance. The study highlights that waste plastic bottles can be efficiently recycled for soil stabilization applications by considering key soil properties such as optimum moisture content, maximum dry density, California Bearing Ratio (CBR), and unconfined compressive strength (UCS).
