Structural Evaluating the Production of Paving Stone by Using Recycled Nylon and Plastic Wastes

This research project is concerned with the Structural Evaluating the Production of Paving Stones by Using Recycled Nylon and Plastic Waste. Nylon and Plastics have become widely used materials in Nigeria, ranging from home, commercial and industrial use. Managing the wastes generated through the industrial booms has become a concern because of its harmful environmental effects. The study work is mainly limited to the Federal Polytechnic Offa and Offa community in Kwara State for materials gathering for data collection. This study assesses the volume of nylon and plastic wastes generated within the study area. Three samples of wastes (polymer) named A, B and C ' sachet water's nylon, packaging nylon and pet bottles', were selected for the process. The recycling process involves sorting, cleaning, and drying. Further, the thermoplastic materials undergo a melting process using a temperature range of 150-165oC with the aggregate compositions of moulding materials and produced eight prototype models of paving stones. The sample was subjected to a water absorption test, flexural test, and oven test and observed that; samples A, B and C in ratios 1:1, 1:1, and 1:2 have greater values of tested parameters compared to paving stone made with conventional cement and granite dust. Hence, paving stones made from nylon and plastic materials (Polymers) have greater strength and resistance to water absorption. Therefore, the researchers suggested an open platform for a close collaboration between the government and the professionals in the built environment to encourage the use of waste material to replace cement.
