With the right tools and calculations you could launch the unrecyclable wedding invitions into orbit and then on a path to reach the sun by 2040, which will burn the non-biodegradable trash into an eco-friendly firey abyss.

I can help you with the calculations, but IŽll need some nitrogen tetroxide, or, if you have the resources, 20 liters of high-density liquid hydrogen. If you can meet me in Amsterdam the weekend after the wedding, we can do this in a couple of hours. Just tell the guests to bring their invitations with them to the wedding.
