I am the same way with all of the garbage. I have the blister packs from my pills and the casing from the suppositories. I am not only weird about the amount of garbage but I always worry someone is going to look in my trash and think, Omg what is wrong with this person. If I go to someones house I put my garbage in a plastic bag and take it home to throw out.
The suppositories do not reach as far up. They may not be as successful at treating your inflammation. I wouldn't worry to much about the amount of waste, it is necessary for you to stay healthy. To put things in perspective, there are people who create a lot more waste than you I am sure.
