What Happens During Cremation

Legal Authorization and Initial Preparation

Before cremation can begin, specific legal requirements must be met:

• Cremation Authorization Form: The individual with legal authority—typically the next of kin or an executor—must sign an authorization form. This grants formal consent for the procedure.
• Issuance of Permits: Local authorities, such as the county health department or coroner’s office, must provide a cremation permit. In cases of unusual or suspicious circumstances, the coroner or medical examiner may conduct further investigation.
• Mandatory Waiting Period: Most states require a waiting period after death before cremation is allowed, commonly between 24 and 48 hours. Processing paperwork and permits often takes up to 72 hours.

These safeguards ensure proper verification, as cremation is an irreversible process.

Chain of Custody and Identification

From the moment the deceased is received by the funeral home or crematory, tracking procedures are followed:

• Assigning a Unique ID: The body is tagged (usually with a metal or stainless steel ID coin or tag with a unique number or barcode) that stays with the remains throughout.
• Continuous Documentation: Every transfer and step in the process is recorded to ensure accurate identification. This ID tag is returned to the family with the ashes.
• Storage: The body is typically held in climate-controlled storage while paperwork is finalized.

Preparing the Body for Cremation

Preparation follows standardized guidelines:

• Personal Effects: Jewelry and other personal items are removed and returned to the family unless specifically requested to be cremated with the body.
• Medical Devices: Pacemakers, battery-operated, or radioactive medical devices are removed to prevent possible hazards during the process.
• Combustible Container: The deceased is placed in a sealed, leak-resistant, and fully combustible container (often sturdy cardboard or wood). Metal caskets are not used; rental caskets with removable interiors may be available for ceremonies.

The Cremation Process (Flame-Based)

The transformation of remains takes place in a specially designed furnace:

• Cremation Chamber (Retort): The container and body are placed in the retort, lined with heat-resistant material.
• High Temperature: The furnace operates between 1,400 and 2,000 degrees Fahrenheit. The process duration is typically between 1.5 and 4 hours, depending on body characteristics and equipment.
• Result: All organic tissue is vaporized, leaving only bone fragments.

Processing the Remains

After cremation:

• Cooling and Collection: Bone fragments are removed from the chamber, cooled, and checked for any remaining non-organic materials.
• Metal Removal: Materials such as dental work or surgical pins are separated and disposed of in accordance with environmental and health guidelines.
• Grinding into Ashes: Bone fragments are placed into a cremulator, which reduces them to powder form (““ashes”” or ““cremains””).
• Ash Return: Ashes—typically 4 to 8 pounds for an adult—are sealed in a container with the ID tag. The process from permit to return of ashes typically takes several days after cremation.

Alternative: Water-Based Cremation (Alkaline Hydrolysis)

By 2025, more than 20 states in the U.S. permit water-based cremation, also known as alkaline hydrolysis:

• Process: The body is placed in a pressurized chamber with water, heat, and alkalizing agents, which break down tissue and leave only bone fragments.
• Outcome: Bone fragments are then processed in a similar manner to flame-based cremation. This method is considered more environmentally friendly due to its lower carbon footprint and reduced emissions.

Costs and Accessibility

• Direct Cremation: Direct cremation typically starts at approximately $995 for basic services, but can range from $2,000–$3,000 at full-service funeral homes, depending on location and additional services.
• Memorial Services and Extras: Additional services such as viewings, ceremonies, or upgraded containers may increase costs.
• Obese or Overweight Individuals: Cremation is feasible for individuals of any size but may require specialized equipment. Additional charges of $100–$400 are commonly noted for individuals over 300 pounds.

Family Presence and Special Requests

• Witnessing: Some crematories allow families to observe the start of the cremation process, depending on facility policy and family preference.
• Viewings: Embalming is performed only if there is to be a viewing prior to cremation, and solely for that event.
• Personal Items: Some small, combustible personal effects may be included with the deceased at the family’s request.

Ashes and Final Disposition

Following cremation:

• Release: Ashes are provided only to the person designated in the authorization form.
• Options for Memorialization: Ashes may be kept by the family, interred in cemeteries or columbaria, scattered (subject to local regulations), or incorporated into keepsakes such as jewelry, glass art, or memorial reefs.
• Unclaimed Remains: If ashes remain uncollected—commonly after 90 days—funeral homes may respectfully scatter or inter the remains according to applicable policies and regulations, after making reasonable efforts to contact the family.

Environmental Considerations

• Traditional Cremation: There are emissions associated with traditional flame-based cremation, but current regulations and advancements in technology help to minimize environmental impact.
• Water Cremation: Water-based cremation is gaining in popularity as more states approve its use due to its environmental profile.

What Families Can Expect

• Timeframe: The process from time of death to cremation typically requires at least 3 days, with ashes returned up to a week later in most cases.
• Support and Guidance: Funeral homes and crematories provide information and assistance throughout all steps in the process, ensuring compliance with regulations and addressing family questions.
• Ceremonies: Memorial services may be held either before (with the body present) or after cremation, often featuring the urn.
