Abstract: A method and a system for comminuting and cleaning waste plastic are described. For this purpose, waste plastic is comminuted and pre-washed in a wet mill and then cleaned in a washing system. The resulting wastewater is subjected to mechanical filtration and flotation and then temporarily stored as circulating water. Based on this, some of the circulating water is returned to the wet mill as first process water and some of the circulating water is returned to the washing system as second process water. In this way, the first and second portions of the circulating water may be specifically adapted to the respective water requirements of the wet mill and the washing system as well as to the required water qualities, if necessary with selective post-cleaning of the second portion of the circulating water. As a result, the fresh water requirement for the process described may be minimized.
