A “living coffin” has been used in a burial for the first time in the Netherlands. The coffin is made out of mycelium, a complex system of thread-like fibers that form the vegetative part of fungi. The coffin, called Living Cocoon, was developed by a Netherlands-based startup known as Loop to serve as a more sustainable option for burials. Speaking to Metro Newspaper, Bob Hendrikx, the founder of Loop, confirmed the successful burial.
