ABSTRACT:
A device for the encapsulation of syringes and other hazardous plastic waste having needles or other sharp elements, the device having a melt chamber with a reciprocating compaction head, the weight of the compaction head providing the force to conform molten plastic into a puck covering the needle points. Flow release apertures allow for escape of gases and provide an overflow conduit for excess molten plastic. The puck adheres to the compaction head and is ejected back into the melt chamber for removal and disposal.
