How Long Does a Body Last in a Green Burial: From Womb to Nature

A green burial is an eco-friendly approach to laying the deceased to rest. The body is returned to the earth in a biodegradable casket or shroud, allowing for natural decomposition. Factors to consider include:

1. Elements of a green burial — Biodegradable materials are used and burial sites are chosen to promote the growth of native plants and wildlife.
2. How long does a body last in a green burial — The soft tissue of the body decomposes within several weeks but the bones can last several months to a few years.
3. The stages of natural decomposition — These include fresh, bloat, active decay, advanced decay, and dry remains.
4. Factors that affect the decomposition process — Temperature, humidity, soil composition, presence of scavengers, and access to oxygen influence the rate of decomposition.

What is a Green Burial?

A green burial means using biodegradable materials for caskets or shrouds, avoiding embalming chemicals, and choosing natural burial sites.

This is a way to honor the deceased while reducing the environmental impact of a burial.

By allowing the body to return to nature, green burials create a sense of connection with the world and encourage land conservation efforts.

Are Green Burials Safe for the Environment?

Green burials are exceptionally eco-friendly funerals, especially when compared to a traditional burials.

• By using biodegradable materials and avoiding embalming fluids, green burials ensure that there is no risk of water contamination or soil pollution.
• The decomposition process is aided by microorganisms in the soil, and any potential contaminants from the body are broken down in an eco-friendly manner. 
• Moreover, concerns about animals disturbing the burial site are minimized through adopting best practices such as ensuring a sufficient burial depth (animals can’t smell anything buried deeper than three feet) and using natural barriers like stones or dense vegetation.

Additionally, unlike traditional burials, not only are green burials safe they avoid a lot of environmental issues. According to Wikipedia each year, 22,500 cemeteries across the United States bury approximately:

• 70,000 m³ of hardwood caskets
• 82,000 kg of steel caskets
• 12,700 kg of steel vaults
• 2,500 kg of copper and bronze caskets
• 1,484,000 kg of reinforced concrete vaults
• 3,200 m³ of embalming fluid which usually includes formaldehyde

Elements of Green Burial

To ensure efficacy and minimal environmental impact, there are a number of elements to consider when arranging a green burial:

• Green burial grounds — these dedicated sites are designed to facilitate natural decomposition. They often feature native vegetation to blend harmoniously with the environment.
• The absence of embalming – is a fundamental principle. Instead, if necessary, the body may be kept cold prior to the burial to maintain its condition without resorting to artificial preservation methods.
• Degradable coffin — Green burial coffins, made from materials like bamboo, wicker, or unprocessed wood, break down naturally over time.

• Shroud — An alternative to coffins, a shroud is a simple cloth wrapping that envelops the body. It facilitates decomposition while maintaining the eco-friendly essence of the green burial concept. Similarly, clothing for a green burial needs to be biodegradable; simple, unbleached fabrics like cotton, linen, or wool are excellent choices. 

How Long Does a Body Last in a Green Burial: Decomposition

Decay, scientifically referred to as decomposition, begins immediately after death, and is a biological and chemical process.

Different forms of burials, such as aqua burials and those in eco-friendly cemeteries, allow the natural breakdown of the body to occur without interference. 

• In eco-friendly cemeteries, decomposition takes place within the soil. Microorganisms collaborate with oxygen and moisture to dismantle the body. Enzymes within cells aid in tissue breakdown, while insects and underground scavengers also play their part. This process can take a few months to a few years. The nutrients from decomposing bodies enrich the soil, which benefits surrounding plants.
• In aqua-green burials, where the body is submerged in water, aquatic conditions affect the process; soft tissues are broken down by bacteria, leading to gas release and potential bloating. Anaerobic bacteria join in to speed up decomposition by breaking down proteins and fats. This process can be fairly rapid, and decomposition is complete within a few weeks to months.

During both processes, bones decay at a slower rate. Eventually, the organic matter of the body transforms into compounds that nourish the surrounding environment.

The Stages of Natural Decomposition

The stages of natural decomposition encompass several distinct phases.

• The initial stage – known as the “fresh” stage, begins immediately after death and lasts for around 1 to 3 days.
• Followed by the “bloat” stage – which lasts approximately 4 to 10 days, characterized by the accumulation of gases and the swelling of the body. 
• The “active decay” stage – then sets in, lasting up to several weeks, during which the breakdown of soft tissues occurs through microbial activity. 
• The subsequent “advanced decay” stage – extending over months to years, involves the gradual consumption of remaining tissues and bones by insects and microorganisms. 
• Finally, the “dry remains” stage – completes the process, where only bones and hair persist. 

To facilitate natural decomposition, can you be buried without a casket? Yes. It’s often considered the most eco-friendly way to be buried. Make sure to you understand local rules and regulations, as requirements vary by country.

What Affects the Decomposition Process

The decomposition process is influenced by several key factors that can either accelerate or decelerate its progression. 

• The cause of death, overall body condition, size, disease progression, medications, use of pain relievers, storage methods, and environmental conditions, all play a role in the decay timeline.
• Temperature plays a significant role; warmer conditions tend to expedite decomposition, while colder environments slow it down. Soil type and composition also matter, with sandy or loamy soils promoting faster decay compared to clay-rich soils.
• Humidity is another critical element; higher humidity levels facilitate microbial activity and decomposition, whereas drier conditions can impede the process.
• Access to oxygen is essential as well; aerobic decomposition, which occurs in the presence of oxygen, is generally faster than anaerobic decomposition which occurs in oxygen-deprived environments.

Conclusion

Green burials are revolutionizing the funeral process by embracing eco-conscious practices that align with nature. The absence of embalming chemicals and the use of biodegradable materials allows for natural decomposition to occur so that the body does not last as long in a green burial.

As the body naturally integrates with the earth, the process can take several months to a few years, fostering a deep connection between life and the environment. Green burials embody a harmonious cycle, allowing the departed to seamlessly become one with nature over time.
