Developing fibre-reinforced cement paving blocks as a method of fiber waste disposal

Abstract

The textile industry contributes significantly to global environmental pollution, generating over 110 million tons of waste annually [1], with severe consequences for the environment. Out of Textile and apparel waste, when Textile waste fibers are considered, both pre-consumer and post-consumer wastes, present a massive challenge. Despite the potential for recycling, the rates remain low [2]. In this project, the focus is on repurposing textile waste fibers as a reinforcement material for pedestrian walkway paving blocks, addressing both waste management and paving block performance. By utilizing polyester waste fibers and recycled polyester waste fibers, the study aims to create a new market for fiber waste, benefiting multiple industries and the environment. The project's significance lies in reducing the environmental impact of the textile fiber-related industry in Sri Lanka, where textile waste is a major problem. However, challenges in recycling certain fiber types exist, and more research is needed to optimize the process and improve the performance and durability of fiber-reinforced cement paving blocks. Implementing this approach can lead to a circular economy, reduced waste management costs, and decreased greenhouse gas emissions.
