Why Human Composting is Revolutionizing End-of-Life Care
How do you compost a body through natural organic reduction? The process involves three main methods:
- Controlled-Vessel NOR - Bodies decompose in steel vessels with wood chips at 131-160°F over 8-12 weeks
- Forest-Mound Composting - Outdoor burial mounds using passive solar heat for 60-90 days
- Agrarian Windrow Method - Farm-style composting with heavy equipment over 4-6 months
Each method transforms human remains into nutrient-rich soil while saving one metric ton of CO₂ compared to cremation or burial.
Human composting, also called natural organic reduction (NOR), has gained legal status in 12 U.S. states as families seek eco-friendly alternatives to traditional burial and cremation. The process costs between $4,000-$7,000 and produces approximately one cubic yard of usable soil per body.
"Knowing that their body will be able to return to the earth is deeply comforting," explains one family member who chose composting over cremation. This sentiment reflects a growing movement toward regenerative death care that mimics the forest floor's natural decomposition cycle.
As American Mortuary Coolers, we've worked with funeral facilities nationwide to design temperature-controlled environments essential for modern death care, and we've seen how understanding how do you compost a body helps funeral directors prepare for this emerging service option. Our experience with mortuary refrigeration systems provides insight into the precise environmental controls needed for successful human composting operations.
How Do You Compost a Body: Controlled-Vessel Natural Organic Reduction (NOR)
How do you compost a body using the most advanced method available today? The controlled-vessel approach represents the gold standard of human composting, taking place inside specially designed stainless-steel vessels that create perfect conditions for natural decomposition.
Companies like Recompose have spent years perfecting this process, which transforms a human body into rich, fertile soil in just 8-12 weeks. Think of it as nature's recycling program, but with precise scientific controls to ensure everything happens safely and efficiently.
The magic happens when you combine human remains with a carefully balanced mixture of wood chips, alfalfa, and straw. This isn't just random organic matter - these materials are specifically chosen to create the ideal carbon-to-nitrogen ratio that beneficial microbes absolutely love.
The body rests inside a steel cylinder measuring about 8 feet by 4 feet, where temperatures stay between 131-160°F. This heat range is crucial because it eliminates harmful pathogens while keeping the good bacteria happy and active. Regular aeration ensures oxygen flows throughout the vessel, because these helpful microbes need to breathe just like we do.
Every few weeks, the vessel contents get rotated to distribute moisture and nutrients evenly. After 5-7 weeks in the vessel, followed by 3-5 weeks of soil curing, you end up with approximately one cubic yard of beautiful, nutrient-rich soil weighing 500-1,000 pounds.
The investment for this process runs between $4,000-$7,000, depending on your provider and which services you choose. Currently, this method is legal in Washington, Colorado, Oregon, Vermont, California, New York, Nevada, Arizona, Maryland, Delaware, Minnesota, and Maine.

Step-by-Step NOR Setup — how do you compost a body in a facility?
The journey begins with a laying-in ceremony where families can gather for final goodbyes before their loved one enters the composting vessel. This moment provides closure while honoring the choice to give back to the earth.
The body is gently positioned on a bed of calibrated bedding materials - those same wood chips, alfalfa, and straw we mentioned earlier. These aren't just tossed in randomly. The mixture is precisely measured to achieve that critical 30:1 carbon-to-nitrogen ratio that makes decomposition happen efficiently.
Temperature probes are carefully inserted throughout the vessel to monitor conditions around the clock. The system maintains steady temperatures between 131-160°F, with a minimum of 131°F held for at least 72 hours to eliminate any harmful pathogens.
Oxygen bursts are introduced through controlled systems to keep the environment aerobic - meaning oxygen-rich. Without proper airflow, the process would turn anaerobic and create unpleasant odors instead of clean decomposition.
The vessel rotates periodically, like a gentle tumbler, redistributing materials to ensure even breakdown throughout. After 5-7 weeks, the resulting compost moves to curing bins where it's aerated for another 3-5 weeks until all microbial activity stabilizes into finished soil.
What Happens to Bones, Teeth & Implants?
While soft tissues decompose completely during the composting process, bones and teeth need a little extra help. After the initial composting phase, everything gets screened to separate the larger bone fragments that remain.
These bones then go into a cremulator - the same specialized equipment used in crematoriums - which reduces them to fine mineral powder. This bone powder gets mixed back into the finished soil, adding valuable calcium and other minerals that plants absolutely love.
Medical implants like artificial joints, dental fillings, and pacemakers are carefully removed and sent for recycling according to medical waste protocols. Mercury from dental fillings gets extracted separately to prevent any environmental contamination.
The result? Pure, clean soil that's safe for gardens, memorial trees, or wherever families choose to spread their loved one's final gift to the earth.
Method 2: Forest-Mound & Aerated Windrow Composting
Picture a gentle mound nestled in a forest clearing, where nature does most of the work. The forest-mound method offers a more rustic answer to how do you compost a body, relying on the earth's own rhythm rather than high-tech equipment.
Herland Forest in Washington State has become the pioneer of this approach, successfully composting both livestock and human remains using what they call "passive solar heat." Instead of steel vessels and precise temperature controls, this method creates an outdoor mound of wood chips, straw, and other organic materials that harness the sun's warmth and natural microbial processes.
The body is carefully placed within this organic cocoon, where the surrounding materials provide both insulation and the carbon needed for healthy decomposition. The process typically takes 60-90 days - a bit longer than controlled vessels, but with a gentler, more natural pace.
What makes this method particularly appealing is its simplicity. There's no need for expensive steel equipment or complex monitoring systems. The mound does its work quietly, requiring mainly volunteer labor and careful attention to the basics of composting science.
Many conservation lands are exploring this model because it fits naturally into forest management practices. The finished compost enriches the soil where it's created, supporting new growth in a beautiful cycle of renewal.
Is This "how do you compost a body" at home?
The forest setting might make this seem like a backyard option, but hold on - it's not quite that simple. Even though this method looks more "DIY," state permits and green burial rules still apply strictly.
Most states that allow human composting require licensed facilities with health department oversight. Home-scale operations remain prohibited, even where human composting is perfectly legal. The regulations exist for good reasons - protecting groundwater, ensuring proper pathogen elimination, and maintaining community health standards.
But here's the beautiful part: family participation is often welcomed at licensed forest-mound facilities. Families can help with the laying-in ceremony, assist in creating the mound, or participate in planting memorial trees using the finished soil. It's a hands-on way to honor a loved one while staying within legal boundaries.
Some natural burial grounds are partnering with composting facilities to offer hybrid services. These partnerships combine the ceremonial aspects families cherish with the environmental benefits of composting - giving you the best of both worlds.
Wildlife, Odor & Pathogen Controls
A well-managed forest mound shouldn't attract unwanted visitors or create unpleasant smells. The secret lies in the 2-foot carbon blanket that surrounds the body. This thick layer of wood chips, sawdust, or straw acts like nature's own air filter, trapping odors and creating an environment that scavengers find unappealing.
Biofilter flora can be planted around the composting area to process any escaped gases while making the site blend beautifully into the forest landscape. Think of these plants as the final cleanup crew, polishing the air naturally.
Temperature control happens differently here than in steel vessels, but it's just as important. The mound must reach 130-150°F internally to eliminate dangerous pathogens like E. coli. Scientific research on pathogen safety shows that proper forest-mound composting achieves the same pathogen elimination as other methods.
Regular monitoring of temperature, moisture, and pH levels keeps everything on track. When the carbon-to-nitrogen ratio stays balanced, you get clean decomposition without the problems. It's like tending a very special garden - one that requires patience and attention, but rewards you with rich, life-giving soil.
Method 3: Agrarian Windrow Inspired by Livestock Composting
When farmers lose livestock, they've been using windrow composting for decades. Now this same proven method is being adapted to answer how do you compost a body on a larger scale. The agrarian windrow approach brings farm-tested techniques to human composting, using the same heavy equipment and protocols that have safely processed thousands of animals.
Picture a long, carefully shaped mound stretching across a field - that's a windrow. The process starts with laying down a thick base of wood chips or sawdust, creating an absorbent foundation. The body is placed on this carbon-rich bed, then covered with more organic materials to hit that sweet spot of a 30:1 carbon-to-nitrogen ratio that microbes love.
The real magic happens with the turning. Specialized windrow turners or tractors with custom attachments regularly flip and mix the pile, pumping fresh oxygen into the compost while redistributing moisture and nutrients. This keeps temperatures humming between 130-150°F - hot enough to eliminate pathogens but not so hot that it kills the beneficial microbes doing the work.
The timeline stretches longer than other methods, typically taking 4-6 months from start to finish. But this approach can handle multiple bodies at once, potentially making it more economical for regions with higher volumes. The trade-off is space - you need significant acreage and agricultural zoning to make this work.
Legal & Ethical Roadblocks
Even in states where human composting is perfectly legal, home-scale operations face serious problems. Zoning laws typically restrict these activities to agricultural or industrial areas, far from residential neighborhoods. Your backyard composting dreams will likely hit a wall with local health boards who require extensive permits and monitoring protocols.
The prion exclusions are particularly strict. Bodies that died from diseases like Creutzfeldt-Jakob disease, Ebola, or tuberculosis are off-limits for composting due to pathogen survival concerns. Pacemakers with lithium batteries also need special handling before the composting process can begin.
Local health departments don't just rubber-stamp these operations either. They maintain ongoing oversight, requiring regular testing of finished compost for pathogens and heavy metals. These safety measures protect public health but also limit where and how agrarian windrow composting can realistically operate.
The reality is that while the farming community has the space and equipment for this method, the regulatory framework often pushes human composting toward more controlled, facility-based operations instead.
Comparing Results, Impact & Cost
All three composting methods offer significant environmental benefits compared to traditional burial and cremation. Human composting uses one-eighth the energy of conventional burial or cremation and prevents one metric ton of CO₂ from entering the atmosphere per body. Cremating one corpse emits an estimated 418 pounds of carbon dioxide, equivalent to driving 470 miles in a car.
The controlled-vessel method produces the most consistent results, yielding approximately one cubic yard of pathogen-free soil in 8-12 weeks. Forest-mound composting takes 60-90 days but requires less infrastructure and energy input. The agrarian windrow method can handle larger volumes but takes 4-6 months and requires heavy equipment.
Cost varies significantly between methods. Controlled-vessel NOR ranges from $4,000-$7,000, comparable to traditional funeral costs. Forest-mound composting may cost less due to reduced infrastructure needs, while agrarian windrow operations could offer economies of scale for higher volumes. Scientific research on emissions confirms the climate benefits of all composting methods.
Where Is Each Method Legal Today?
As of 2024, human composting is legal in 12 U.S. states: Washington, Colorado, Oregon, Vermont, California, New York, Nevada, Arizona, Maryland, Delaware, Minnesota, and Maine. Washington was the first state to legalize the practice in 2019, followed by Colorado and Oregon.
Each state has specific regulations governing composting operations:
- Washington requires licensed facilities with health department oversight
- Colorado permits both facility-based and potentially home-scale operations under certain conditions
- California restricts operations to licensed funeral establishments
- New York allows composting at certified facilities with strict pathogen testing requirements
Several other states have pending legislation, including Massachusetts, Pennsylvania, and Illinois. The regulatory landscape continues to evolve as more states consider legalizing human composting in response to growing public interest.
When NOT to Compost a Body
Certain medical conditions and circumstances make human composting inadvisable or illegal. Bodies that died from Ebola, tuberculosis, or prion-based diseases like Creutzfeldt-Jakob disease are typically excluded due to pathogen survival concerns. These pathogens can survive the composting process and pose public health risks.
Pacemakers with lithium batteries must be removed before composting to prevent fire hazards and environmental contamination. Other medical implants like artificial joints can be removed and recycled, but radioactive implants from cancer treatments may require special handling or waiting periods.
Bodies that have been embalmed with formaldehyde are generally not suitable for composting, as the chemicals can inhibit microbial activity and contaminate the finished soil. Some facilities may accept embalmed bodies if sufficient time has passed for chemical breakdown, but this extends the composting timeline significantly.
Frequently Asked Questions about Body Composting
How long does the entire process take from start to finish?
When families ask how do you compost a body, timing is often their first concern. The answer depends on which method you choose, but all options are significantly faster than traditional decomposition.
Controlled-vessel NOR moves the quickest at 8-12 weeks total. Your loved one spends 5-7 weeks in the specialized composting vessel, followed by 3-5 weeks of soil curing to ensure the compost is fully stabilized and ready for use.
Forest-mound composting takes a middle path at 60-90 days. The timeline varies based on weather conditions - warmer climates speed things up, while cooler temperatures slow the process. The hands-on nature of this method also allows for adjustments that can influence timing.
The agrarian windrow method requires the most patience at 4-6 months. The larger pile sizes and more passive approach mean everything happens at nature's pace, but this method can handle multiple bodies simultaneously if needed.
Can the resulting soil be used anywhere?
The beautiful thing about human composting is that it creates genuinely useful soil - not just a memorial keepsake. The finished compost works wonderfully in gardens, forests, and conservation projects, though each state has its own rules about where it can go.
Most states treat composted human remains similarly to cremated ashes for scattering purposes. This means families have flexibility in choosing meaningful locations. However, the soil cannot be sold commercially - it's either returned to families or donated to approved conservation organizations.
Many facilities have developed partnerships with land trusts and conservation groups to use the soil for ecosystem restoration projects. Imagine your loved one helping restore a damaged forest or creating habitat for wildlife. It's a powerful way to give back to the earth.
Some families use their soil to plant memorial trees or create dedicated garden spaces. Others donate it to community gardens or environmental restoration projects, knowing their loved one continues contributing to life.
How does composting compare to cremation on price?
Human composting costs $4,000-$7,000, putting it right in line with traditional funeral options. To put this in perspective, the median cost of a funeral with cremation hit $6,971 in 2021, while a funeral with viewing and burial averaged $7,848 - and that's before adding plot and headstone costs.
While composting might seem pricier than basic direct cremation, it actually includes services that funeral homes typically charge separately. You're getting comprehensive care plus something valuable at the end: nutrient-rich soil instead of ashes.
The real value becomes clear when you consider the environmental impact. You're saving one metric ton of CO₂ compared to cremation, using one-eighth the energy of conventional burial, and creating something that actively helps the environment rather than just avoiding harm.
Many families find the cost worthwhile because they're investing in a process that aligns with their values while still honoring their loved one with dignity and care.
