You probably know that composting banana peels and eggshells can help reduce your negative impact on the environment. But did you know that, once you die, you can do that with your body, too?

Human composting — also known as natural organic reduction or the reduction of human remains — is the practice of placing a dead body in a reusable vessel with biodegradable materials that foster the transformation into nutrient-dense soil that can be returned to loved ones or donated to conservation land.

The notion of going green even in death might sound far-fetched, but California has become the latest state to sign a human composting bill into law, set to go into effect in 2027. Washington became the first state to legalize human composting in 2019, followed by Oregon, Colorado and Vermont.
