Human Composting in Maryland: What's Legal, What's Not, and How It Compares to Water Cremation

The two most discussed alternatives to conventional burial and flame cremation — human composting and water cremation — have very different legal statuses in Maryland. One has been specifically authorized by state law, with clear rules on how the resulting material is handled. The other is caught in regulatory uncertainty following a 2024 Attorney General ruling.

If you are pre-planning your own disposition or making decisions after a death, knowing where Maryland actually stands on each option will save you from misinformation that is common on national funeral planning websites.

Human Composting (Natural Organic Reduction) in Maryland

Human composting — formally called natural organic reduction (NOR) — is the process by which a body is placed in a vessel with organic materials (wood chips, straw, alfalfa), and microbial activity converts the remains into soil over the course of several weeks. The result is a dense, nutrient-rich material that resembles compost.

Maryland has passed legislation accommodating natural organic reduction. The law uses the term "soil remains" to describe the material produced by this process.

What You Can and Cannot Do with Soil Remains in Maryland

Maryland Health-General § 5-514 sets specific rules for the disposition of soil remains:

You may:

• Keep soil remains at home, in a container, indefinitely
• Place soil remains on private property (your own land) with your own consent as the property owner
• Place soil remains on another person's private property with their written permission
• Donate soil remains to a land trust, conservation area, or other organization that accepts them

You may not:

• Scatter or place soil remains on public lands, public parks, or public waterways without specific authorization
• Scatter soil remains on any private property without the written permission of that property owner
• Use soil remains as fertilizer for food crops intended for human consumption
• Use soil remains as feed or fertilizer for livestock

The restriction on food production is a public health measure and applies even when the property owner consents to the remains being on their land. The rules differ in this respect from cremated ashes (conventional cremation), which have fewer use restrictions.

Is Human Composting Available from Maryland Funeral Homes?

As of 2026, the human composting industry in the United States is still concentrated in Washington State, where NOR was first legalized, and a handful of other early-adopter states. Because Maryland's legislation is relatively recent and the infrastructure for NOR (specialized vessels, controlled environment facilities) is capital-intensive to build, access through local Maryland funeral providers is limited.

Families in Maryland who want NOR as their disposition method may need to work with an out-of-state provider that accepts transport of remains. This involves coordinating a burial transit permit for transport across state lines and working with a provider licensed in the receiving state.

This is a rapidly changing landscape. If NOR is important to you, contact the National Funeral Directors Association or search providers through the Return Home or Earth Funeral directories for current availability in the mid-Atlantic region.

Water Cremation (Alkaline Hydrolysis) in Maryland

Alkaline hydrolysis — sold commercially under brand names like "aquamation," "green cremation," and "bio-cremation" — uses a water and lye solution at elevated temperature and pressure to dissolve soft tissue, leaving only bones. The bones are then processed into a fine powder (similar in appearance to cremated remains from flame cremation) and returned to the family. The resulting liquid is a sterile effluent that enters the wastewater system.

Maryland's Legal Status for Alkaline Hydrolysis

This is where Maryland diverges sharply from states like California, Florida, and Colorado, which have fully legalized and commercially active alkaline hydrolysis industries.

In 2024, the Maryland Attorney General issued a judgment that created significant regulatory friction for commercial alkaline hydrolysis operators in the state. Without a clear statutory framework authorizing water cremation as a licensed disposition method, commercial providers face substantial legal uncertainty about operating in Maryland.

As of 2026, alkaline hydrolysis is not clearly legal for commercial funeral operators in Maryland. Families who specifically want water cremation cannot reliably arrange it through a Maryland funeral home. Unlike human composting — which has explicit statutory language accommodating it — water cremation lacks that legal foundation in Maryland at this time.

If legislative or regulatory changes occur, funeral homes offering this service would need to be licensed by the Maryland Board of Morticians and Funeral Directors, and the Board has not yet issued guidance creating a pathway for licensure.

How This Compares to Conventional Cremation

Maryland's conventional flame cremation rules are clear and well-established:

• A mandatory 12-hour waiting period after death before cremation can occur (many national websites incorrectly state 24 or 48 hours — the Maryland rule is 12 hours)
• Medical Examiner authorization is required for every cremation, regardless of cause of death
• Medical Examiner fees run $63–$100
• Once received by the crematory, the body must be cremated within 48 hours or refrigerated at 40°F or below
• Families may keep ashes, scatter them on their own property, scatter on others' property with permission, or scatter at sea (EPA rules apply — 3 nautical miles from shore for burial at sea)

Choosing an Alternative Disposition: Practical Steps

If you are pre-planning and want to choose human composting or are hoping for water cremation, the practical steps differ:

For human composting:

1. Research current NOR providers who accept Maryland remains (check for out-of-state options if no local provider is available)
2. Document your choice in a witnessed written directive, which gives your wishes legal priority over family members' preferences under Maryland Health-General § 5-509
3. Understand the soil remains rules before deciding how you want the material handled — you cannot scatter it on public land without authorization

For water cremation:

1. Monitor Maryland legislative developments — this could change in the coming sessions
2. Consider documenting conventional flame cremation as your backup preference in your written directive
3. If water cremation becomes available, ensure any provider you work with holds a valid Maryland license

The Maryland Funeral Laws & Consumer Rights Guide covers the full written directive process and explains how to document alternative disposition preferences in a legally recognized way under Maryland law.

The Environmental Angle

For families who are attracted to these options because of environmental concerns, it is worth noting that both NOR and alkaline hydrolysis have substantially lower carbon footprints than conventional flame cremation, and both produce no formaldehyde (embalming) or non-biodegradable materials (concrete vaults, metal caskets).

Natural burial — burial without embalming, vault, or sealed casket — is also fully legal in Maryland and may be the most immediately accessible low-impact option for families who cannot find a local human composting provider. See our post on natural burial in Maryland for that option in detail.
