Method for recycling all waste plastics in particular mixed plastics

A method for recycling of all types of waste plastic, in which agglomerate or compactate, from flakes or other plastic parts are ground in at least one refiner stage in the presence of water, to form ground material emerging from the at least one refiner stage;

• from at least a portion of the ground material emerging from the at least one refiner stage, fine particles are removed with the water, the remaining ground material is washed and mechanically dehydrated and dried and, optionally, the dehydrated ground material is again ground in another refiner stage in the presence of water and then dehydrated and dried, characterized in that the grinding of the agglomerate or compactate is performed in the at least one refiner stage using a disk refiner having two disks, the disks of which have engaging teeth, which are arranged separated on concentric circles, wherein there are gaps between neighboring teeth of the concentric circles and the gaps of the concentric circles are each big enough that the agglomerate or compactate to be ground can pass freely through the gaps.
