Using fibers in concrete applications has become a common practice. This is partly due to improvement in ductility and crack control of concrete. There will be an added advantage if these fibers come from a waste source as it would lead to reduction in environmental pollution and the need for landfill spaces. This paper forms the initial part of a wide range investigation on the use of waste plastic fibers in concrete applications. This study attempts to apply the concept of sustainability and reduces the environmental pollution by producing fibers from waste plastic straws and adding them to plain concrete to improve the tensile strength and ductility. The experimental work was carried to examine the effect of including waste plastic fibers on the properties of concrete. The fiber percentages used were 0%, 0.5%, 1.5% and 3%. Testing included workability, density, compressive and tensile strength, ultrasonic pulse velocity and length change. Generally, the addition of waste plastic fibers increased the tensile strength, whereas there was a slight reduction in compressive strength when more plastic fibers were added. The ultrasonic pulse velocity and density show a slight decrease in the presence of fibers.
