Trashing your Christmas trees

We Minneapolis residents think that when we put our Christmas trees at the curb they're getting collected for composting just like yard waste in the summer, right? Well that turns out to not be the case. Apparently the city is allowed to throw those particular trees in with the trash even though it's illegal to do with yard waste. Why? They're considered 'ornamentals' and are exempt from the yard waste ban. There was some discussion about this at work, and hopefully the policy will change this year. We're keeping ours in our yard for now, and we'll put it out once yard waste season starts.
