Disposing of waste incense ash is a challenging and environmentally hazardous task. In the qualitative analysis has revealed that it contains 47.74% of the alkaline substance CaO. This study focuses on utilization of incense ash to create roof tiles and bricks and explores their potential for acid rain neutralization. After more than a year and multiple experiments involving roof tiles exposed to acid rain runoff and acid rain immersed experiment, it was observed that the efficiency of acid rain neutralization in incense ash samples is positively correlated with the proportion of incense ash content. The results indicate that roof tiles made with 5% to 20% incense ash are suitable for use in the Taiwanese environment, and even after a year of exposure to a natural environment, they still possess good capabilities of acid rain neutralization. For those seeking both acid rain neutralization and carbon capture capabilities, a proportion of 10% to 20% incense ash is optimal. Incorporating more than 20% incense ash into the product will reduce the viscosity of ceramic items, making them easy to deform. Compared to traditional roof tiles, incense ash products offer characteristics such as lower production costs, high durability, and efficient acid-base neutralization. They can serve as a novel development in roof tile materials or bricks. In the production of bricks, it was discovered that cement tends to encase incense ash granules. Therefore, ceramics with larger pores mixed with incense ash are used in 3D printing to rapidly create bricks suitable for various environmental applications, simultaneously possessing capabilities of carbon capture and acid rain neutralization.
