Flexural Strength of Ceiling Results from Plastic Waste Conversion

Abstract

Abstract The high development of construction is a factor in accelerating municipal solid waste. The large volume of plastic waste threatens natural ecosystems and human health. Plastic recycling can reduce the negative impact. This study aims to test the performance of a plastic waste melting device, convert plastic waste into a ceiling, and test the quality of plastic ceilings. Plastic waste is converted into ceiling by melting the plastic waste and then printing it on the ceiling mold. The plastic ceiling is tested to measure the material strength and compare it with conventional ceilings. The performance test of plastic melter showed good performance because the device reached the melting temperature of the plastic, which is 160 °C within 4 hours. The process of converting plastic waste into ceilings aims to reduce plastic waste. Density and Modulus of Rupture (MOR) tests were carried out to determine the quality of the ceiling. The density of plastic ceilings has a value of 0.87 g/cm3. The MOR value for plastic ceilings has a value that is not much different from ceiling materials on the market, which is 3 N/mm2. Therefore, plastic ceilings can be an alternative to reduce the distribution of plastic waste.
