Well, if eco-friendly is the way you want to leave this world, your options have just gotten greener. The Natural Burial Company now offers biodegradable coffins so that you can basically compost yourself once you're gone. As part of a larger trend toward "natural" burials, which require no formaldehyde embalming, cement vaults, chemical lawn treatments or laminated caskets, biodegradable coffins are more eco-friendly than cremation which still requires the burning of fossil fuels. Cost options range from $100 for a basic cardboard box to over $3,000 for a handcrafted, hand-painted model. You can also choose from natural-fiber shrouds to fair-trade bamboo caskets lined with unbleached cotton. Most of these eco-friendly burial products come from overseas, but the idea is catching on in the USA.
