People don’t like to talk about dying and funerals, but it’s something will all do at some point. Of course you may decide to donate all your organs or donate your body to science. However you’ll still likely to need a coffin and there are ethical ones out there!
One company is Ecoffins which is a World Fair Trade company and makes Willow, Bamboo and even cardboard coffins.
Somerset Willow is a UK company that hand makes Willow coffins, and also grow their own Willow, so UK from start to finish.
If you want to make use of your coffin before death then there is Shelves for Life, which is basically a flat pack coffin rearranged into a shelving unit, then when you die it get turned into your coffin.
