At the first stage of this work, waste printed circuit board was pyrolyzed under vacuum in a self-made batch pilot scale fixed bed reactor, and the glass fiber (GF) was separated from the pyrolysis residues by gravity method and purified by calcination in the air. Then, the GF/polypropylene (PP)composites was prepared by means of injection molding. The(More)
The constant growth in generation of waste printed circuit boards (WPCB) poses a huge disposal problem because they consist of a heterogeneous mixture of organic and metallic chemicals as well as glass fiber. Also the presence of heavy metals, such as Pb and Cd turns this scrap into hazardous waste. Therefore, recycling of WPCB is an important subject not(More)
