1. A system comprising:
a first medical waste container, the first container having a bottom and a projection that extends from a bottom inner surface of the first container, the first container being configured so that a second medical waste container is nestable within the first container and on the projection of the first container to form, between the first container and the second container nesting within the first container, a packet safe space between the bottom inner surface of the first container and a bottom surface of the second container;
within the packet safe space, a packet at least partially dissolvable in an aqueous liquid, the packet molded around at least a portion of the projection of the first container; and
an amount of solidifier, contained within the packet, capable of solidifying a volume of the aqueous liquid accommodated by the first container,
wherein, when the volume of the aqueous liquid is introduced into the one of the first container, the packet is configured to release at least a portion of the amount of solidifier into the volume of the aqueous liquid to achieve firm solidification of the introduced volume of the aqueous liquid.
