    Abstract

    Solid waste management is becoming a sustainability issue in highly industrialized societies. Recycling or reuse of solid waste is desirable to reduce the adverse impact of this material. The vast annual production of printed circuit board (PCB) waste in Taiwan creates environmental concerns because of the leaching of toxic chemicals into landfills. This study assessed the feasibility of utilizing resin powder and glass fiber recycled from PCB waste as a partial replacement of fine aggregate (natural river sand) in concrete. It also established a comprehensive test program to promote the use of recycling waste for waste reduction. The crushed powder of PCB mixed with standard mortar in fixed volumetric mix proportion, as sand:cement:water = 2.75:1:0.485 was the control group to test the fresh and hardened properties of the material. The test results of hardened specimen properties showed that the addition of PCB resin powder should be less than 10 %, and the addition level of glass fiber should be less than 2 %. The engineering properties and durability matched those of the cement mortar of the standard control group. Because toxic chemicals released from PCB powder and hardened concretes were found to be less than the tolerance limit in the local ordinances, waste PCB can be used in cement mortar, providing an alternative for recycling industrial waste PCB.
