You might want to look into what’s called promession. It’s a way to turn you into fertilizer.
Your question is hard to answer. Because when it comes to how corpses are dealt with, the rules aren’t federal in the US. So you need to look at the states. And the rules for burials, release of the ashes, etc. are possibly set at county level. Likewise in Europe, the rules differ by countries and even within those by whatever subdivisioning applies. I looked it up for Germany, which has some federal rules about how to handle a corpse. But then 16 state laws on what is allowed in terms of final resting places. So far as I can see a Viking burial will not be allowed in places where cremation must happen at a specific temperature, the ashes may not be spread outside cemeteries, or other environmental laws forbid it. So that’s basically nowhere then. Being shot out of a cannon will probably fail at an environmental hurdle or the fact that civilians can’t own active military equipment.
