Abstract
The present invention relates to the use of liquid-crystal displays (LCDs), and to processes for the recycling thereof. The processes according to the invention are characterised in that the LCDs are employed at least partly as replacement for other raw materials. In general, the LCDs are thermally treated here at a temperature in the range from 900 to 1700° C.
Claims14
A process for the material recycling of LCDs, comprising replacing raw materials other than LCDs at least partly by LCDs in a material recycling process, wherein the LCDs are thermally treated as raw material or added material in a rotary-tube furnace at a temperature in the range from 1100 to 1300° C., wherein the proportion of LCDs as raw material or added material in a composition comprising said LCDs and raw materials other than LCDs is 1 to 20% by weight.
A process for the material recycling of LCDs, comprising replacing raw materials other than LCDs at least partly by LCDs in a material recycling process, wherein the LCDs are thermally treated as raw material or added material in a rotary-tube furnace at a temperature in the range from 1100 to 1300° C., wherein the LCDs are in un-comminuted form.
A process for the material recycling of LCDs, comprising replacing raw materials other than LCDs at least partly by LCDs in a material recycling process, wherein the LCDs are thermally treated as raw material or added material in a rotary-tube furnace at a temperature in the range from 1100 to 1300° C., wherein the LCDs are in unbroken form.
