Is Natural Organic Reduction Legal in California? What San Diego Families Need to Know
Quick Answer
Yes — natural organic reduction (human composting) is legal in California. Governor Gavin Newsom signed Assembly Bill 351 into law on September 18, 2022, and the law takes effect January 1, 2027, which is when licensed facilities may begin offering it. The process gently transforms a body into about one cubic yard of nutrient-rich soil over roughly 30 to 45 days using only natural microbial activity — no flame and no chemicals. Because the service is not yet available in California until 2027, families who want a low-impact option today can choose aqua cremation, which is already legal and offered at Bravo Family Mortuary in San Diego.

More San Diego families are asking about natural organic reduction — often called human composting. They hear about it while pre-planning their own arrangements, or while honoring a loved one who felt a deep connection to the earth. They want a clear answer to one question first: is it legal in California, and can our family choose it?
The short answer is yes, it is legal — but the timing matters. This guide explains exactly what the law says, how the process works, when it becomes available, and what earth-friendly options your family can choose today. If you have questions specific to your situation, Bravo Family Mortuary is available 24 hours a day at 1-833-762-7286.
Is Natural Organic Reduction Legal in California?
Yes. California legalized natural organic reduction when Governor Gavin Newsom signed Assembly Bill 351 into law on September 18, 2022. The law makes California one of a small group of states — alongside Washington, Colorado, Oregon, Vermont, and New York — to formally allow the process.
There is one important detail for families to understand: AB 351 takes effect on January 1, 2027. That is the date on which licensed facilities in California may begin offering natural organic reduction. Until then, no provider in the state can legally perform it. The California Cemetery and Funeral Bureau, which licenses and regulates funeral providers, oversees the process.
In other words, the choice is now protected by law — it is simply not yet available. That distinction is why pre-planning matters: you can record your wishes today and have your family informed the moment the option opens.
What Is Natural Organic Reduction, Exactly?
Natural organic reduction is the formal name for a process many people call human composting or terramation. All three terms describe the same idea: gently transforming a body into clean, nutrient-rich soil using nothing but natural biological activity.
It is the most literal version of returning to the earth. In nature, organic matter breaks down and becomes soil over many years. Natural organic reduction creates the ideal conditions for that same transformation to happen safely and with dignity in a contained, controlled setting — in weeks rather than years.
The result is approximately one cubic yard of soil, which families can use to nourish a garden or a memorial tree, or donate to conservation land that restores forests and natural habitats.
How Does Natural Organic Reduction Work? (Step by Step)
Understanding the process helps many families feel more at peace with the choice. Here is what happens, step by step:
Preparation
Your loved one is placed in a reusable vessel along with natural plant materials such as wood chips, alfalfa, and straw. These materials create the right balance of carbon and nitrogen for the transformation to begin.
Controlled conditions
The vessel is sealed and kept at the temperature, moisture, and oxygen levels that naturally occurring microbes need to thrive. No chemicals are added — the process relies entirely on biology.
Microbial transformation
Over roughly 30 to 45 days, beneficial microbes gently break the body down, the same way organic matter returns to the earth in nature. The contained, controlled setting simply accelerates what would otherwise take years.
Screening and curing
Any inorganic materials, such as medical implants, are removed. The remaining soil is allowed to cure, leaving a clean, stable, nutrient-rich material.
What remains
The process yields approximately one cubic yard of soil — enough to fill a few wheelbarrows. It is safe, sterile, and rich in nutrients.
Returning to the family
Families can take some or all of the soil home to nourish a garden, a tree, or a memorial planting. Soil that the family does not keep is often donated to conservation land, where it helps restore forests and natural habitats.
Natural Organic Reduction vs. Traditional Cremation
Both honor a loved one with care. The differences lie in the method, the timeline, and the environmental impact.
| Traditional Flame Cremation | Natural Organic Reduction | |
|---|---|---|
| Method | Intense heat and flame | Natural microbial breakdown |
| Duration | 2–3 hours | Approximately 30–45 days |
| Energy use | High — fossil fuel intensive | Very low — biological process |
| Emissions | CO₂, carbon monoxide released | No combustion emissions |
| Result | Bone fragment ash | ~1 cubic yard of nutrient-rich soil |
| Legal in California | Yes — always legal | Yes — signed in 2022, available beginning Jan. 1, 2027 (AB 351) |
| Available at Bravo today | Yes | Not yet — aqua cremation is the available green option now |
Who Typically Chooses Natural Organic Reduction?
- Environmentally conscious families — If your loved one cared deeply about the planet, returning them to the earth as living soil is a way to extend that commitment. No flame, no fossil fuel combustion.
- Those who feel close to nature — Many people are drawn to the idea of nourishing a tree, a garden, or restored forest land as their final gift.
- Pre-planners thinking ahead — Because the option becomes available in 2027, people arranging their own services often document this wish now. Compare it with aqua cremation to decide what fits your values best.
- Families exploring every option — Bravo Family Mortuary walks through every available disposition method — burial, traditional cremation, and aqua cremation — with no pressure, and keeps families informed about natural organic reduction as it becomes available.
What Green Options Are Available in San Diego Right Now?
Because natural organic reduction will not be available in California until January 1, 2027, families who want a gentle, low-impact choice today have an excellent option already: aqua cremation. Also known as water cremation, it uses a warm water-based solution instead of flame, consumes about 90% less energy than traditional cremation, and produces no direct air emissions.
If you would like to understand how aqua cremation compares, our companion guide, What Is Aqua Cremation?, walks through the process in detail. Bravo Family Mortuary is one of the few funeral homes in San Diego County offering it directly.
