Here is my understanding of the situation. It is probably better to segregate
your waste. Most EHS departments that I have dealt with bulk pack (lg. drums)
the waste we send them. They have the knowledge of compatibility. If we create
some weird cocktail before they get it, it may not be able to go in a bulk
container. This would drive up your disposal costs.
