I think I would wait on that until you go to your Alanon meeting at least and get their suggestions. I'm thinking their suggestions relate to not making excuses for the person, letting them have consequences and not helping them out.
I think dumping bottles will not really help with the actual problem, but I would check with Alanon first as they would prob. know best. I think a big component of the program is detaching and not trying to control the problem such as dumping bottles, or whatever.
