The Growing Movement Toward Sustainable Death Care
Natural composting burial is changing how we think about end-of-life care by converting human remains into nutrient-rich soil through controlled microbial decomposition. This eco-friendly alternative to traditional burial and cremation uses natural processes to create approximately one cubic yard of fertile soil in 8-12 weeks.
Key Facts About Natural Composting Burial:
- Process: Body placed in vessel with wood chips, alfalfa, and straw for 5-7 weeks
- Output: One cubic yard of soil (500-1,000 pounds) per body
- Cost: $2,500-$7,000 compared to $7,000+ for cremation or $10,000+ for traditional burial
- Environmental Impact: Saves 0.84-1.4 metric tons of CO2 and uses 87% less energy than cremation
- Legal Status: Available in 11 U.S. states as of 2024
- Timeline: Complete process takes 8-12 weeks total
The demand for sustainable death care options is growing rapidly. Each year, 2.7 million Americans die, and more families are seeking alternatives that strengthen the environment rather than depleting it. Traditional burials consume over 800,000 gallons of toxic embalming chemicals annually, while cremation produces substantial carbon emissions.
Natural composting burial offers funeral directors a way to serve environmentally conscious families while providing meaningful memorialization options. The resulting soil can nourish memorial gardens, support conservation projects, or help families create living tributes to their loved ones.
As American Mortuary Coolers, we've worked extensively with funeral homes nationwide to support innovative death care practices, including facilities that offer natural composting burial services.
What Is Natural Composting Burial (Natural Organic Reduction)
Natural composting burial transforms how we think about what happens after death. Instead of fighting nature with chemicals or burning bodies at extreme temperatures, this process works with the same gentle forces that have recycled life on Earth for millions of years.
Also called Natural Organic Reduction (NOR) or human composting, this method places human remains in a controlled vessel where beneficial microbes break down organic matter and create rich, fertile soil. It's the same process happening on every forest floor, just carefully managed to ensure safety and optimal conditions.
The process happens in specially designed stainless steel vessels that maintain the perfect balance of temperature, moisture, oxygen, and organic materials. Bodies are surrounded by wood chips, alfalfa, and straw—creating an environment where naturally occurring microbes can thrive and do their transformative work.
Natural composting burial requires no fossil fuels, no toxic embalming chemicals, and no permanent land use. The body becomes part of nature's endless cycle of renewal.
Defining Natural Composting Burial
Natural composting burial returns to humanity's roots—literally. For thousands of years before modern funeral practices, bodies naturally returned to the earth and nourished new life. This sustainable method makes that ancient process safe, controlled, and accessible in our modern world.
Professionals prefer "natural organic reduction" because it captures the scientific precision involved. This isn't backyard composting—it's a carefully monitored change that meets strict health and safety standards while creating soil that can support gardens, trees, and conservation projects for decades.
The process represents a fundamental shift in death care philosophy. Instead of preserving remains indefinitely or reducing them to ash, natural composting burial allows the body to become part of the natural nutrient cycle that sustains all living things.
Origins of the Natural Composting Burial Movement
The story of modern natural composting burial begins with Katrina Spade, an architecture student who asked: "What if we could compost human bodies the same way farmers compost livestock?"
Spade built on decades of research into livestock composting, particularly methods developed for managing animal remains during disease outbreaks. Her research led to founding Recompose, the first company to offer commercial human composting services.
Washington State broke new ground in 2019 by becoming the first state to legalize natural organic reduction. The law took effect in 2020, and since then, ten more states have recognized the environmental and practical benefits of this innovative approach to death care.
How Natural Composting Burial Works: Step-by-Step Process
The natural composting burial process is surprisingly straightforward. The journey begins when a body is gently placed in a custom-designed stainless steel vessel—about 8 feet long and 4 feet tall. These precision-engineered containers create the perfect environment for change.
The body is carefully layered with wood chips, alfalfa, and straw—materials chosen specifically for their ability to support the microscopic life that does all the real work. The vessel becomes a busy ecosystem where billions of beneficial microbes begin their natural process of breaking down organic matter.
Temperature is key to the entire process. The microbes generate their own heat, naturally bringing the temperature to 130-160°F. This temperature range kills harmful pathogens while keeping beneficial organisms thriving. No external heating required.
Oxygen flow keeps everything running smoothly. The vessels rotate periodically, and ventilation systems ensure fresh air reaches every corner. This maintains aerobic conditions that keep the good microbes happy and prevent odors.
The entire 8-12 week process runs on nothing but natural microbial activity. No fossil fuels, no chemicals, no mechanical grinding during the active phase. It's the same process that's been recycling organic matter in forests for millions of years, just optimized for efficiency and safety.
Materials and Microbiology Inside the Vessel
The secret to successful natural composting burial lies in getting the recipe right. It's all about carbon and nitrogen balance—like baking, where proportions matter.
Wood chips provide carbon and create structure, while alfalfa delivers nitrogen that feeds the microbes. Straw adds both structure and aeration, creating tiny air pockets throughout the mixture. The magic ratio? About 25-30 parts carbon to 1 part nitrogen.
The beneficial microbes are already present—some living naturally on the human body, others in the organic materials. These include bacteria, fungi, and other decomposer organisms that break down complex proteins, fats, and carbohydrates into simple nutrients that plants love.
Moisture control requires constant attention. Operators monitor moisture levels carefully, adjusting as needed to keep conditions optimal. Aeration happens through vessel rotation, typically once a week, ensuring oxygen reaches every corner.
Timeline, Bones, Teeth & Implants
The active composting phase lasts 5-7 weeks, during which soft tissues transform completely. Bones and teeth don't break down naturally during this timeframe and need special attention.
After the vessel phase, everything gets carefully screened. Bones and teeth are separated out and reduced to fine powder using specialized equipment. This bone meal gets mixed back into the compost, helping balance nutrients and pH levels.
Metal implants like pacemakers, artificial joints, and dental work are removed during screening. Many of these materials can be recycled.
The soil then enters a 3-5 week curing period in aerated bins. The pH balances to optimal levels (usually 6.5-7.0), and the material develops that rich, earthy smell gardeners recognize. By the end, you have approximately one cubic yard of nutrient-rich soil.

Environmental & Family Benefits of Choosing Natural Composting Burial
When families find what natural composting burial can accomplish for both the planet and their hearts, many describe feeling hope during one of life's most difficult moments. This gentle process transforms grief into something generative—literally creating new life from loss.
The environmental numbers tell a compelling story. Each person who chooses natural composting burial prevents 0.84-1.4 metric tons of CO2 from entering our atmosphere. The process uses 87% less energy than cremation without burning fossil fuel.
Unlike traditional burial, there's no need for concrete vaults, toxic embalming chemicals, or caskets made from hardwood forests. Just natural processes that have been recycling life on Earth for millions of years.
The one cubic yard of nutrient-rich soil that emerges isn't just symbolically meaningful—it's scientifically powerful. This soil can improve growing conditions for decades. Adding just 1% more organic matter to soil helps it retain an extra 20,000 gallons of water per acre.
Perhaps the most profound benefit happens in the hearts of families. Instead of visiting a static grave marker or keeping ashes on a shelf, families can watch their loved one continue nurturing life. Many describe an ongoing sense of connection as they tend memorial gardens or visit trees planted with their loved one's soil.

Carbon Savings and Soil Health
The climate benefits of natural composting burial work on multiple levels. While cremation releases all the carbon stored in a human body directly into the atmosphere as CO2, composting sequesters that carbon in soil where it can remain for decades.
This process also eliminates "embodied carbon"—the emissions created when manufacturing caskets, concrete vaults, and granite headstones. No mining, no industrial manufacturing, no long-distance shipping of heavy materials.
Methane reduction represents another climate win. When bodies decompose in sealed caskets underground, they often create methane—a greenhouse gas 25 times more potent than CO2. The carefully managed aerobic conditions in natural composting burial prevent methane formation entirely.
Laboratory testing reveals that the finished soil typically contains balanced levels of nitrogen, phosphorus, potassium, and sulfur—exactly what plants need to thrive.
Memorialization: What Families Do With the Soil
The flexibility of receiving actual soil opens up memorialization possibilities families often hadn't imagined. Tree planting remains the most beloved choice, with many families creating memorial groves or adding meaningful species to their home landscapes.
Conservation donation appeals to families who want their loved one's final gift to heal damaged landscapes. Land restoration projects, wetland rehabilitation efforts, and reforestation programs welcome these donations.
Raised garden beds create ongoing opportunities for connection. Families grow flowers that bloom on anniversaries, vegetables that feed the family, or herbs that carry memories through scent and taste.
Some families practice ritual scattering, taking handfuls of soil to meaningful places with landowner permission. These "dots of memories" can be visited annually, creating a network of living memorials.
Legality, Cost & Access to Natural Composting Burial in the U.S.
The legal landscape for natural composting burial is evolving rapidly across America. Currently, 11 states have accepted this sustainable death care option, with more legislation pending each year. The process typically costs between $2,500 and $7,000, making it surprisingly affordable compared to traditional burial costs that often exceed $10,000.
Since natural composting burial isn't available everywhere yet, many people are choosing to transport remains to legal states. Commercial airlines regularly accommodate this type of transport, and many funeral homes can handle the logistics.
Pre-planning offers significant advantages. As awareness grows, more providers are offering prepaid programs that start around $100 per month. This approach gives families time to understand the process, lock in current pricing, and plan meaningful ways to use the resulting soil.

States Where Natural Composting Burial Is Legal
Washington State broke new ground in 2019 by becoming the first to legalize natural organic reduction. Colorado, Oregon, and Vermont quickly followed suit. California passed legislation but delayed implementation until 2027.
The recent wave includes New York, Nevada, Arizona, Maryland, Delaware, and Minnesota, bringing the total to 11 states with full legal authorization. Each state develops its own regulatory approach after legalization. Washington and Colorado currently offer the most mature services.
Georgia recently became the 13th state to actively consider legislation, suggesting the momentum continues building. Interstate transport of unembalmed remains is federally legal and commonly used by families in non-legal states.
Typical Pricing and How to Plan Ahead
Natural composting burial pricing reflects both the specialized equipment required and the extended timeline involved. The $2,500-$7,000 range compares favorably to median cremation costs of $6,280 and burial costs of $8,300 according to 2023 National Funeral Directors Association data.
Prepaid programs offer significant advantages beyond financial planning. Companies like Recompose provide monthly payment options starting around $100, while others offer lump-sum prepayment discounts. More importantly, pre-planning ensures availability and gives families time to thoughtfully consider how they want to use the resulting soil.
Insurance coverage varies but is becoming more standardized as the industry matures. Many life insurance policies cover natural composting burial just like other funeral expenses.
As funeral professionals, we've seen how pre-planning reduces stress for families during difficult times. When someone has already chosen natural composting burial and handled the logistics, families can focus on celebrating their loved one's life.
Natural Composting Burial vs. Green Burial vs. Traditional Options
When families face end-of-life decisions, understanding the real differences between natural composting burial and other options helps them choose what feels right. Each method tells a different story about how we want to care for our loved ones and our planet.
Natural composting burial represents the newest approach, changing bodies into nutrient-rich soil that can nourish new life for decades. Green burial takes a more traditional path, allowing natural decomposition in designated cemetery areas without embalming chemicals or concrete vaults. Traditional burial and cremation remain the most familiar choices, though they carry higher environmental costs.

Key Environmental Differences
Natural composting burial delivers the most dramatic environmental benefits of any death care option. Using 87% less energy than cremation and producing zero direct emissions, it actually removes carbon from the atmosphere by storing it in soil rather than releasing it as CO2.
Green burial makes a meaningful environmental difference by eliminating the toxic embalming chemicals that traditional burial uses—over 800,000 gallons annually in the U.S. It also skips concrete vaults and metal caskets that require significant manufacturing energy. However, green burial still requires permanent land use.
Traditional burial carries the highest environmental cost through its use of formaldehyde-based embalming fluids, energy-intensive casket manufacturing, and permanent land consumption. Each traditional burial can tie up 10 square feet of land indefinitely while contributing chemicals to groundwater systems.
Cremation falls somewhere in the middle environmentally. While it eliminates chemical use and permanent land requirements, each cremation consumes energy equivalent to about 30 gallons of fuel and releases stored body carbon directly into the atmosphere.
Practical and Cultural Considerations
Religious and cultural acceptance varies significantly among families and faith communities. Some Christian denominations accept natural composting burial as fulfilling the "earth to earth, ashes to ashes" commitment, while others prefer traditional burial practices. The Catholic Church has expressed concerns about human composting, though individual Catholic families have still chosen this option.
Personalization opportunities differ substantially between methods. Natural composting burial allows families to decorate vessels with meaningful items, visit during the change process, and use the resulting soil for memorial gardens or tree plantings.
The question of ongoing connection often influences family decisions. Traditional burial provides a permanent gravesite where families can visit. Cremation offers portable ashes that can be scattered in meaningful locations.
Natural composting burial creates a different kind of ongoing relationship—one where families can literally watch their loved one nourish new life through memorial trees, vegetable gardens, or conservation projects. Some families find this deeply comforting, while others prefer having a fixed location for remembrance.
Cost considerations also play a practical role, with natural composting burial typically running $2,500-$7,000 compared to $6,280 for cremation and $8,300+ for traditional burial.
Frequently Asked Questions About Natural Composting Burial
What happens to bones and medical implants?
When families choose natural composting burial, they often wonder what happens to the parts of the body that don't decompose as easily.
During the 5-7 week vessel phase, soft tissues transform completely through microbial activity. But bones, teeth, and any medical devices need special handling. Once the initial composting is complete, everything gets carefully screened by trained technicians.
Bones and teeth are pulverized into fine powder using specialized equipment, then mixed back into the compost. This bone meal adds valuable minerals like calcium and phosphorus that plants love, and it helps balance the soil's pH to optimal levels.
Medical implants get recycled whenever possible. Pacemakers, artificial joints, surgical screws, and dental work are removed and sent to appropriate recycling facilities. Any materials that can't be recycled are disposed of following strict medical waste protocols.
How much soil is produced and where can it go?
Each person who chooses natural composting burial becomes approximately one cubic yard of rich, fertile soil—that's about 500 to 1,000 pounds. It's enough to fill a 3x3x3 foot space or several large pickup truck beds.
Most families keep some of the soil for personal memorial projects. There's something deeply meaningful about planting a tree or creating a garden bed using soil that was once your loved one.
Families can keep all, some, or none of the soil—it's entirely their choice. Many take a portion for home use and donate the rest to conservation organizations working on reforestation or land restoration projects.
Just like with cremated ashes, you'll need landowner permission before applying the soil anywhere. The soil can be legally transported across state lines, so geographic distance doesn't limit your options.
Is natural composting burial safe and odor-free?
Safety concerns are completely understandable when considering any new death care option. Natural composting burial has been extensively tested and regulated to ensure both safety and dignity.
The composting naturally reaches 130-160°F for weeks at a time, which eliminates pathogens including E. coli, Salmonella, and other harmful bacteria. These temperatures are actually higher than many pasteurization processes used in food safety.
As for odors, properly managed natural composting burial produces surprisingly little smell. Most people describe it as earthy and pleasant—like rich garden soil after rain. Custom HVAC systems in facilities maintain negative air pressure and advanced filtration to ensure no odors escape.
Before any soil is released to families, it undergoes comprehensive laboratory testing. Technicians check for pathogens, heavy metals, pH levels, and nutrient content to ensure everything meets or exceeds safety standards.
Conclusion
Natural composting burial represents more than just another death care option—it's a gentle return to the earth that honors both our loved ones and the planet we all share. This innovative approach transforms human remains into rich, life-giving soil while dramatically reducing the environmental footprint of saying goodbye.
The numbers speak for themselves: significant carbon savings of up to 1.4 metric tons per person, 87% less energy use than cremation, and the creation of approximately one cubic yard of fertile soil that can nourish new growth for decades. When you add in the elimination of toxic embalming chemicals and meaningful memorialization opportunities through living tributes, it's clear why more families are choosing this path.
What strikes us most about natural composting burial is how it transforms grief into growth. Instead of preservation or destruction, it offers change.
