What exactly is death tech?

What we’re calling death tech is any new technology that is used to dispose of a dead body. (The fancy funeral industry word here is “disposition.”) Older forms of death technology might be burial or cremation. Death technology of the future includes methods like aquamation and natural organic reduction.

There are a surprising number of designers who are working toward reforming body disposition, internment, and memorialization. This New York Times article introduces you to some of these ideas and we discuss them in our Eco Death Takeover video.

Technology can also include new green products, cemeteries, and memorialization options. Here are some examples:

  • The DeathLab is working on an alternative to cremation and earthen burial and designing new public spaces of remembrance intertwined with everyday life.
  • The Santa Coloma de Gramenet Cemetery, outside Barcelona, Spain has converted its municipal burial space into a source for renewable energy with solar panels.
  • The African Burial Ground, located in New York, provides memorialization that integrates scholarship, technology, and civic engagement.
  • With changing lifestyles, lack of space, and environmental concerns numerous countries in Asia have been reimagining their final resting places like these columbariums in Japan, and a “library” for cremated remains in South Korea.

Alkaline Hydrolysis aka Water Cremation or Aquamation

Like Cremation, Alkaline Hydrolysis—also known as Green or Water Cremation

is a method of preparing a dead human body for its final disposition. And like cremation, it’s a process that reduces human remains to bone fragments. But instead of flame, Alkaline Hydrolysis uses water and an alkali solution of potassium hydroxide (KOH) commonly found in household products, which when heated, dissolves the body, leaving behind bone fragments and a sterile liquid. Alkaline hydrolysis is the natural process a body undergoes after burial, which can take up to 25 years. Green Cremation essentially accelerates this natural process to 2-3 hours in a very quiet, controlled environment.

This eco-friendly alternative to cremation recently made headlines following the death of anti-apartheid campaigner and Nobel Peace Prize winner Archbishop Desmond Tutu, when it was announced that he had chosen a plain wooden coffin, and alkaline hydrolysis prior to his passing. Tutu was passionate about the environment and often spoke and wrote about climate change, so it makes sense that his disposition of choice would reinforce his beliefs and life’s work.

The process was explained in-depth in two of our videos, Liquefying Bodies, and more recently in this video, in which an aquamation facility for pets is featured and the procedure is explained in detail. This article details the history of aquamation including current efforts to legalize the process, and here’s an explainer on how aquamation has already been in use with pets in Alkaline Hydrolysis – Seattle Style.

How does aquamation compare to compare to flame-based cremation? Environmentally speaking, it’s estimated that aquamation can cut energy use down by 90%, and greenhouse gas emissions by 35%. Learn why it may well be the future of death care in Why Alkaline Hydrolysis is a Green Alternative. As for other notable differences, the aquamation process allows for about 20-30% more ashes to be retrieved, which are typically white or tan, as opposed to flame cremation ashes that are gray in color.

In addition to Alkaline Hydrolysis being a more sustainable alternative to cremation, this option also provides a path to restoring native Hawaiian burial practices.

Wondering if Alkaline Hydrolysis is legal in your state? Check this current list of laws. You should also know that if you live in a state that doesn’t currently offer Alkaline Hydrolysis, you may be able to find a funeral home in your home state that is partnered with a neighboring one that does provide this option.

Natural Organic Reduction (Human Composting)

Natural Organic Reduction (NOR) also known as human composting, uses the principles of nature, combining microbes, oxygen and plant matter to gently transform human remains into soil, so that our bodies can grow new life after we die. This process was  developed by Founding Order Member Katrina Spade, through public benefit corporation, Recompose. As legalization spreads, other companies have also begun providing NOR services.

But is composting the dead safe? Absolutely, we’ve been doing it with livestock for years.

[The process] is based on the principles of livestock mortality composting, a process which creates heat which in turn kills common viruses and bacteria. Research into mortality composting of livestock has found that the temperature inside the compost reaches 140 degrees Fahrenheit, which is high enough to kill off pathogens. Farmers are using mortality composting in order to safely dispose of their dead livestock, as well as to control odor and runoff. Recompose has fine tuned this process to be appropriate and meaningful for humans in an urban setting.

The process of NOR can strengthen the environment by utilizing climate healing practices and moving away from toxic ones, and prioritizing soil health. Learn more about the environmental benefits of NOR through this graphic.

A bill legalizing the process in Washington State passed in 2019, and as of September 2022, Colorado, Vermont, Oregon and California, have also passed NOR bills, with current efforts to legalize in New York, where the bill is currently awaiting the governor’s signature.

After almost a decade of work and dedication, the first Recompose facility opened in Seattle in 2021. The first operating license for NOR was granted to green burial ground Herland Forest.

The Mushroom Burial Suit and Mushroom Coffins

The Infinity Burial Suit or “Mushroom Burial Suit” was invented by Founding Order Member Jae Rhim Lee, who says: “The power of the suit is that it creates the need for meaningful planning and discussion around death.”

The Infinity Burial Suit is a handcrafted garment that is worn by the deceased.

The Infinity Burial Suit has a built-in bio­mix, made up of mushrooms and other microorganisms that together do three things; aid in decomposition, work to neutralize toxins found in the body, and transfer nutrients to plant life.

In 2020 another mushroom based product made headlines, a coffin called the Loop Cocoon from the Netherlands. The designers are calling it the “world’s first living coffin,” as it is composed of mycelium and wood chips, with a “bed” of moss, plants and various living microorganisms. The Loop Cocoon has already been used in at least one burial.

In the U.S., designer Shaina Garfield also created a coffin called “Leaves”, which incorporates mushrooms. Here, the body is wrapped in a cotton shroud, and secured to a wooden plank with woven fibers that contain fungal spores.

While these products claim to aid and accelerate the process of decomposition, their effectiveness is questionable. Like anything we purchase, effective or not, these items can be meaningful objects that hold value for the individual who chooses it; serving as a symbol of their care for the environment, and subverting the offerings of a traditional funeral.

Jae Rhim Lee’s original mission to foster important conversations about death, remembrance, and the environment, as well as help to ignite our imaginations regarding what is possible, have certainly been accomplished.


Promession, by designer Susanne Wiigh-Mäsak, is a conceptual machine that would rapidly decompose a corpse through a freeze drying process. At this point it is only at the concept/theory stage and is not available for use (hopefully this will change soon). In Kansas in 2019, efforts were made to legalize the option, however, progress was halted when Kansas Attorney General discovered that promession does not meet the definition of cremation under Kansas law and regulation.

In 2020 we dedicated an entire video to the concept of Promession and its progress so far.

Capsula Mundi

Capsula Mundi is an Italian company that has developed a biodegradable egg-shaped burial pod that replaces a casket.

While not significantly different than natural burial, the designers created the pods in response to Italian laws that have made make un-casketed burial difficult. This product is currently a concept and is not actually available.
