Abstract
Cigarette butt is a hazardous solid waste produced in large amounts worldwide, and its improper disposal has been becoming a critical and urgent issue. This work investigates the incorporation of cigarette butt waste as an alternative raw material into an industrial roofing tile body, in replacement to natural roofing tile body by up to 5 wt.%. Roofing tile formulations containing cigarette butt waste were pressed and sintered at 1100 °C. The technical properties of the ceramic roofing tile pieces, including linear shrinkage, apparent density, weight loss, water absorption, and flexural strength, were investigated. The microstructural evolution was accompanied by scanning electron microscopy. The test results showed that cigarette butt waste could be used in eco-friendly ceramic roofing tile with good technical properties, in the range up to 5 wt.%, as a partial replacement for traditional roofing tile body, thus giving rise to a new feasible alternative for the sustainable application of cigarette butt waste.
