ABSTRACT:
The present invention relates to the cleaning of recyclable plastic. More particularly the recyclable plastic is treated at a frequency from 20 to 60 KHz, optionally in the presence of an antiseptic agent and in the absence of a surfactant. This treatment cleans waste, and particularly waste containing protein, such as medical or food waste so it is suitable for recycling.
