In this study, treatment of waste by pyrolysis touchscreen, the touch panel of the plastic part of the waste into oil, a significant reduction of residual solids, make follow-up of precious metals recycling program to reduce solvent use quite a lot. This will enhance the value of waste re-use touchscreen. In this study, pyrolysis dispose touchscreens to assess the feasibility of recycling oil.In the pyrolysis experiments can be found in the solid residues and liquid product yield decreases as the pyrolysis temperature increases and rising.Optimum conditions for pyrolysis, the touchscreens is not broken in the pyrolysis temperature of 550 ℃, steam pyrolysis residence time is less than 6.7 min, 2 hours under the conditions of pyrolysis, the liquid can get more product (> 34.12%), and less of the solid residue 20.69%.The liquid products of distillation after distillation temperature 150 ℃, 230 ℃ and 300 ℃ for range, heat values were 7661.5,8028.7 and 8113.9 kcal / Kg, and the crude oil market, the class can be seen, although there are still differences, but the heat value not in terms of low calorific value fuel.
