As part of my continuing series on the trappings of death, allow me to present the Ecopod - the environmentally friendly compressed paper coffin. Looks like they're still ramping up for production, but what a neat idea. Even if you go with a traditional vault burial, this should be much less expensive. And you get a choice of designs to boot! (I'd recommend against the gold leaf version shown on the website... seems a bit too Cleopatra, somehow).
