For years, Tui Davidson has been thinking about what happens after death.
The Canberra-based founder of advocacy group Earthly Remains began researching alternatives to traditional burials after the death of a friend's father in 2019.
An urban planner committed to sustainability, he left Ms Davidson questioning why a life lived in service of the environment could not be fittingly farewelled.
Burials require land, materials and maintenance while cremation relies on high-temperature furnaces that release greenhouse gases.
That search eventually led her to a little-known process called natural organic reduction, better known as human composting.
Now, after years of advocacy, Ms Davidson is celebrating a milestone.
Independent Sydney MP Alex Greenwich plans to introduce a bill on Thursday that would pave the way for human composting in NSW.
