Natural burial is completely different to composting. Have you read the article?
When someone dies, their body is taken to a human composting facility [..] After wrapping the deceased in a simple shroud, friends and family carry the body to the top of the core which contains the natural decomposition system [..] It would be done in a contained vessel which [..] would be rotated to provide physical disruption so oxygen could access all parts of the composting material. This would also help control the moisture level.
By the time we completed our trials, we were developing material that was very pleasant to handle, it was a very fine compost that was relatively stable, [and] it smelled good
Where in Europe is this standard practice, exactly?
Active composting isn't. However most graves seem to already be efficient enough at it that you can bury a new corpse in one every few years without being blocked by the remains of the previous inhabitant.
Other posts in this thread mention issues with the soil composition, like if it has a high amount of clay, bodies are well preserved. Really may depend on where specifically you're burying the bodies.
