There is a large variety of electrical and electronic equipment products, for example liquid crystal display television sets (LCD TVs), in the waste stream today. Many LCD TVs contain mercury, which is a challenge to treat at the recycling plants. Two current used processes to recycle LCD TVs are automated shredding and manual disassembly. This paper aims to present concepts for semi-automated dismantling processes for LCD TVs in order to achieve higher productivity and flexibility, and in turn increase the value of the recycled materials, improve the work environment for operators and remove mercury from the recycled materials. A literature review and two empirical studies were performed to be able to present a concept for dismantling direct illuminated LCD TVs. The process used a circular saw and/or a band saw to machine two cuts in LCD TVs to gain access to the mercury-containing cold cathode fluorescent lamps inside. This conceptual process is compared to the other processes found in the literature.
