When I read the original post, I didn't get the impression it was waste, but rather an unopened container of the product, which could be used.
I am well aware of the "cradle to grave" process when dealing with industrial products. I owned a small manufacturing company for 22 years and a large part of our overhead was disposal of regulated waste. Every six weeks when the Safety-Kleen truck pulled in, you could hear my checkbook scream.
I was very careful what I allowed in the door. Even household products are treated differently. Use Simple Green at home and dispose of the dirty solution down the drain. Use it in a manufacturing environment and it needs to be drummed up for "proper" disposal. It used to cost $185/drum for our waste which included dirty coolant, tramp oils, absorbent pads and Speedy-Dry.
I am glad to be out of it.
