What Happens to the Body After Death: A Complete Guide for Families

The short answer: After a death, families must make decisions about the body — burial, cremation, donation, or other options — often within 24–72 hours. Understanding the options helps families make choices that honor their loved one and their own values.

Body Disposition Options After Death

When someone dies, the family must make decisions about the body — typically within 24–72 hours (and more urgently in warmer climates or without refrigeration). The main options in the United States are: traditional burial, cremation, natural/green burial, body donation to science, and increasingly, newer options like alkaline hydrolysis (aquamation) and human composting (natural organic reduction). Each has different costs, timelines, religious implications, and environmental impacts.

Traditional Burial

Traditional burial involves embalming, a casket, and interment in a cemetery. It allows for open-casket viewing and preserves the body for a longer period before burial. Costs include funeral home services, casket, cemetery plot, grave opening and closing fees, and grave marker — typically $7,000–$12,000 total or more. Many religious traditions (Jewish, Muslim) do not permit embalming or open casket; traditional burial for these communities follows specific religious protocols.

Cremation

Cremation is increasingly common in the US — now exceeding burial rates — and is typically less expensive ($1,500–$5,000 for direct cremation without services). The cremated remains (commonly called "ashes," technically "cremains") can be kept in an urn, scattered (legally in many locations), buried, or incorporated into memorials. Some religions prohibit cremation (traditional Judaism, Islam); others have no objection. Families can hold a memorial service before or after cremation.

Natural/Green Burial

Natural burial involves placing an unembalmed body in a biodegradable shroud or simple casket without a burial vault, allowing natural decomposition. It is more environmentally sustainable, less expensive than traditional burial, and legal in all US states. Green burial grounds (conservancies) are available across the US; the Green Burial Council certifies facilities. Death doulas are often familiar with green burial options in their region.

Newer Options: Aquamation and Human Composting

Alkaline hydrolysis (aquamation) uses water, heat, and alkali to decompose the body, leaving bone fragments similar to cremation remains. It is more environmentally sustainable than flame cremation and legal in approximately 28 states. Human composting (natural organic reduction) uses a vessel, wood chips, and microbes to compost the body into soil over several weeks. It is legal in a growing number of states and offered by specialized companies.

Frequently Asked Questions

How long do families have to decide what to do with a body?

Most funeral homes and coroners require a decision within 24–72 hours, though refrigeration can extend this. In warmer climates or without refrigeration, the timeline is shorter. Pre-planning eliminates this time pressure.

What is the difference between burial and cremation?

Burial involves interment of the intact body in a cemetery; cremation uses heat to reduce the body to bone fragments (cremains). Cremation is generally less expensive, offers more flexibility for memorial timing, and is legal and practiced across all major religions in some form (except traditional Judaism and Islam).

Is green burial legal?

Yes — natural/green burial (unembalmed body in a biodegradable container, without burial vault) is legal in all US states. Requirements vary by state. The Green Burial Council certifies facilities and provides a directory of green burial options.

What is aquamation and how is it different from cremation?

Aquamation (alkaline hydrolysis) uses water, heat, and alkali to decompose the body — leaving bone fragments similar to cremation. It is considered more environmentally sustainable than flame cremation and is legal in approximately 28 states. The remains are similar in appearance to cremation.

Can I donate my body to science?

Yes — body donation to medical schools and research institutions is free and provides a meaningful legacy. Different organizations have different eligibility requirements. After study, remains are typically cremated and returned to the family or scattered. Contact individual medical schools or organizations like Science Care for information.
