Human composting saves carbon through a combination of factors. The process uses 87% less energy than cremation, which typically uses fossil fuel to create sustained heat of over 1,600 degrees Fahrenheit for 3 to 4 hours.
No casket or coffin is used during human composting, nor is a concrete grave liner required – all items that add to the carbon footprint of a death.
When human composting transforms the organic material of our bodies, the carbon is captured, or sequestered, in the soil created. Rather than being released as carbon dioxide gas through exhaust during a cremation or as a hydrocarbon gas like methane, the carbon contained in each body returns to the earth. As the nutrients in the compost are used over time by the plants in contact with it, the impact of a person’s choice for human composting continues to expand exponentially.
