Compared with traditional illumination light sources, LED lighting sources are more environmentally friendly and consume less power. In recent years, their usage is increasing year by year. Therefore, the development of appropriate recycling and treatment strategies as well as reuse technologies has become the same goal of international countries. In Taiwan, the waste LED lighting sources begin to be recycled from 2018. Currently, there are few companies is engaged in recycling of waste LED lighting sources. However, in recycling companies, it is still difficult and costly to process the recycled plastics, resulting in the decrease of the willingness of domestic companies to engage in recycling of waste LED plastics. We have completed the followings in this project, (a). Dismantling verification and testing analysis of waste plastic lampshade from ton-level LED waste lighting source, (b). Optimization test of recycled pellets from waste lampshade, (c). Field verification to the optimization technology of recycling plastic pellet waste lampshade by small batch mass production test, (d). Trial manufacturing of a prototype product for high value reuse of waste lampshade, (e). Carry through a field verification to verify the high-value product made of waste lampshades, and (f). Promotion of the recycling industry chain associated to the waste lampshade resource, etc. Through this research project, we expect to improve the recycling value of domestic LED waste plastic lampshade, and to diversify their application domain.
