Distinguished results are very well, but there are still lighting equipment except tube lighting and industrial special lamps without recycling. A great deal of the amounts of waste will increase environmental pollution, but the recycling treatment plants in Taiwan are only four. It is the bottom line for treatment of waste fluorescent lamps and industrial special lamps. Without suitable storage, landfills will result to having lamps broken thus increases the mercury vapor in the air which pollutes the environment. The study will focus on cold cathode fluorescent lamp （CCFL）fluorescent powder, lamp fluorescent powder, super high pressure mercury lamp, UV lamp, lamp exhaust pipe pilot experiments by thermal desorption. The results show that super high pressure mercury lamp, UV lamps and lamp exhaust pipe can reach above 99.9% efficiency. Lamp fluorescent powder can reach 98%. Cold cathode fluorescent lamp（CCFL）fluorescent powder can reach between 69.37~93.39%. Cold cathode fluorescent lamp（CCFL）fluorescent powder efficiency will be affected by increasing temperatures. The increasing temperatures will be the main control factor. Analysis drawn form experiment of releasing mercury shows that temperatures should be controlled at above 550℃ for better efficiency.
