In this study, we developed materials with high adsorption and removal performance of NO_2 gas, thereby decreasing air pollution, by exploiting the porous nature of ceramics produced when clay and crushed waste GFRP are mixed before firing. First, we examined the NO_2 gas adsorption and removal abilities of various materials, such as metals, plastics, wood, mortar, and ceramics made from clay. The results indicated that ceramics made from clay have high adsorption and removal ability for NO_2 gas. We then examined the NO_2 adsorption and removal abilities of ceramics produced by firing mixtures of clay and crushed GFRP. The results indicated that ceramics containing crushed GFRP at 20 to 60% of the total mass have high NO_2 gas adsorption and removal ability. These ceramics may be used as pavement blocks and tiles with an air cleaning function.
