Recycling of toner cartridges
Toner cartridges before treatment
According to the EU Directive 2002/96 / EC, toner cartridges must be taken out of the printers and copying machines before recycling, since the toner dust contained is harmful to health.
Above all, however, when cartridges are used commercially, considerable numbers of cartridges are produced which cannot be refilled owing to their design or damage.
Toner cartridges are normally destroyed in waste incineration plants. Often, however, they are also used in processing plants with insufficient explosion protection. Against this backdrop, URT Umwelt- und Recyclingtechnik GmbH in Karlstadt decided to develop plant concepts for recycling toner cartridges.
The plant concept described is enabling an automatic removal of the toner powder from the toner cartridge. The unopened cartridges are fed to a shredding device via a feeding unit and are coarsly broken. Thereafter, a sieving machine separates the cartridge components from the toner powder.
