I did something similar when I set up the hazardous waste system at
Catalytica many moons ago. Numbered waste bottles were checked out to
named individuals who were responsible for their contents. This avoided
the problem of folks using odd, potentially inappropriate, containers
and also let us keep track of accumulation start dates. Identity and
amount of all additions were recorded on a tag attached to the finger
ring. The type of waste allowed in the container was indicated by
colored tape around the body of the bottle so it was obvious even from a
distance. After collection, bottles with compatible contents were
emptied into a drum and the tags placed in an envelope taped to it. Once
full, it was a simple matter to summarize the contents by examining the
collection of tags.

This replaced the previous "system" that led to the discovery of a
bottle containing five liquid layers, helpfully labelled "waste".
