Question: how long does it take for a body to decompose if not embalmed?
Answer: When buried naturally - with no coffin or embalming - decomposition takes 8 to 12 years. Adding a coffin and/or embalming fluid can tack on additional years to the process, depending on the type of funerary box. The quickest route to decomposition is a burial at sea. Underwater, corpses decompose four times faster.
