Recycling of waste printed circuit boards

摘要

Purpose - The purpose of this paper is to present an update and the latest results from work on a project aimed at enabling waste printed circuit boardrn(WPCB) recycling to become more environmentally friendly and efficient.rnDesign/methodology/approach - A new system was proposed and studied individually under laboratory and factory conditions, which consisted ofrnlossless component removal, component classification, waste crushing/separating processes, and application of crushed non-metallic particles torndevelop resin composites.rnFindings - The use of these novel processes, including component lossless removal, component classification, waste crushing/separating processes,rnand application of crushed non-metallic particles to develop resin composites can be combined to give a more sustainable treatment process for printedrncircuit boards recycling.rnResearch limitations/implications - Most parts of the WPCBs recycling system have been used. Further development work should be undertaken tornestablish the whole system in a factory-scale environment in order to enhance the system efficiency.rnOriginality/value - The paper details how individual treatment technologies can be combined to enable a more environmentally friendly and efficientrnsystem for treatment of WPCBs which offers the benefits of reducing pollution and complete resource recovery for WPCBs.
