Living Coffin

Loop is a Dutch start-up that has created a biodegradable coffin made out of mycelium (underground root structure of mushrooms) instead of wood. The coffin is filled with moss to stimulate decomposition.
Creator Bob Hendrikx told Reuters "Mycelium is nature's biggest recycler. It's continuously looking for food and transforming it into plant nutrition."
Mycelium also processes toxins and turns them into nutrients and was used at Chernobyl to clean up the soil after the nuclear disaster.
The coffin is grown like a plant within one week at Loop's lab at TU Delft by mixing mycelium with wood chips in the mould of a coffin.
Once buried, the coffin will disintegrate within 30 to 45 days, bodies will decompose within 2 to 3 years, instead of 10 to 20 years within traditional coffins.
