Since 2020, Loop Biotech has been making biodegradable caskets out of mycelium, the root-like structure of mushrooms, and hemp. Unlike traditional wooden caskets, which are often treated with chemicals that leech into the soil, the company’s offerings are made of natural materials that enrich the soil as they biodegrade—a process that only takes 45 days after burial.

So far, Loop Biotech has sold about 2,500 caskets in Europe—primarily in the Netherlands, but also in Germany and other parts of central Europe. But Ancker-Robert’s father, Mark Ancker, has just become the first person in the U.S. to be buried in Loop Biotech’s mycelium casket, called the Living Cocoon. “It was dignified, and beautiful,” says Ancker-Robert, who buried her father in a forest clearing on his property. “I have confidence that my dad will be fully part of the garden by winter.”
