And i know many European funeral directors use less formalin compared to US or Canada (dilluted with water) when they embalm, because the aim is short-term preservation, as the cemeteries re-use old graves, the natural decomposition of the body is encouraged. Since the climate is cold and wet, the embalming may cause adipocere formation (known as ‘grave wax’) in wet soil and that’s something unwanted..In Germany, they sometimes use some chemicals to accelerate the decomposition.
