Should We Compost Human Bodies?

Process Innovation

Katrina Spade, an architect, pioneered the concept of human composting, inspired by agricultural practices of composting livestock. She envisioned a respectful process where individuals are placed in individual vessels with a mix of alfalfa, straw, and wood chips, transforming into soil within 30 days 1. This innovative approach respects human sentimentality, offering a "hotel for the dead" rather than a mass composting facility 2.

If you can compost a cow, you can compost a human.

The pilot study in 2018 involved six volunteers, including a 93-year-old named Darby, who embraced the idea, marking a significant step in human composting 1.

   

Pathogen Management

Ensuring the safety of human composting involves meticulous pathogen management. Thomas Bass from Montana State University explains that the heat generated by microbial activity in compost piles can destroy many pathogens, similar to processes used in agriculture 3. However, some resilient pathogens, like those causing tuberculosis, can survive, necessitating regulations to prevent composting of bodies with certain diseases 4.

It destroys such a wide range of pathogens. Foot and mouth disease, avian influenza, plenty of bacteria, salmonella.

Despite these challenges, experts like Bass are confident in the safety of human compost when proper procedures are followed 3.

   

Outcomes & Results

The outcomes of human composting trials reveal both scientific and emotional impacts. Micah Truman describes the transformation of bodies into nutrient-rich soil, which families can use to nurture plants, creating a poignant connection to their loved ones 5. The process, now legal in several states, offers an environmentally friendly alternative to traditional burial and cremation methods 6.

This method not only reduces carbon emissions but also provides a meaningful way for families to honor their deceased 6.
