A disposal system for sharps, such as contaminated needles or syringes, comprising a container for receiving and storing the sharps. A sharp instrument is inserted through an entry opening. When the sharps within the container have reached a certain level, a coagulant is poured into the container. This coagulant hardens and encompasses the sharps. This process can be repeated at intervals until the container is full. The lid is then closed and the container ready for disposal in a landfill or some other appropriate location.
