To utilize waste glass fiber-reinforced plastic (GFRP) and to reduce water pollution in rivers and lakes, we aimed to develop a water treatment material that could purify polluted water. This is achieved by exploiting the porous nature and high permeability of ceramics produced by mixing crushed waste GFRP with clay before firing the resultant mixture. To evaluate the water-quality purification ability of ceramic, filtering tests of methylene blue (MB) aqueous solution on several kinds of ceramic samples made using GFRP containing 40% glass fiber were carried out. Then, the mechanism of ceramic MB absorption was examined by measuring ceramic specific surface area, pore size distribution, permeability and pH of the MB aqueous solution before and afire filtering. The ceramic made by mixing 60% GFRP with particle size of ~0.5 mm or less with clay before the mixture was fired at 1273K, exhibited a high MB absorptivity. The ceramic which possessed the largest specific surface area in ceramic samples had the highest MB absorptivity. The measured pH suggested that MB absorption was caused by ionic exchange. It is expected that ceramics made from clay and waste GFRP could be used as filter materials for water-quality purification.
