Abstract
In order to decrease the total amount of landfilled industrial waste by reuse and/or recycling of the industrial solid waste, the porous ceramics with activated carbon species was prepared from industrial solid wastes and its characterization were investigated. Sludge from gravel plant and sawdust from wood plant were used as the industrial solid wastes (ISW). The molded body after kneading these ISW's with bentonite and activator were calcined at 850°C for 1 hour under N2 atmosphere. Black powder after grinding the calcined body with added activator exhibited a high adsorption ability for methylene blue molecules in liquid phase, and possessed large specific surface area. This result indicates that the carbonized sawdust can be efficiently activated by the activator during calcination process, even though the ISW's was used as source materials.
