Human Composting Now Legal in California

 This weekend, Gov. Gavin Newsom signed a bill into law that makes human composting legal in the state beginning in 2027. The bill, AB-351, makes California the fifth state to allow human composting since it was first legalized in Washington in 2019 (Oregon, Colorado, and Vermont are the other places where you can make yourself into mulch)....Burying a dead body takes about three gallons of embalming liquid per corpse—stuff like formaldehyde, methanol, and ethanol—and about 5.3 million gallons total gets buried with bodies each year. Meanwhile, cremation creates more than 500 pounds (227 kilograms) of carbon dioxide from the burning process of just one body, and the burning itself uses up the energy equivalent of two tanks of gasoline. In the U.S., cremation creates roughly 360,000 metric tons of carbon dioxide each year.

It’s a no-brainer, then, to think of greener alternatives. The most common process for human composting—and the one laid out in the new California law—is called natural organic reduction, which involves leaving the body in a container with some wood chips and other organic matter for about a month to let bacteria do its work. The resulting mulch (yep, it’s human body mulch) is then allowed to cure for a few more weeks before being turned over to the family. Each body can produce about a cubic yard of soil, or around one pickup truckbeds’ worth. According to Garcia’s release, this process will save about a metric ton of CO2 per body.
