Somewhere in Kent [Washington State], tucked anonymously into acres of warehouses and light-industrial workshops, the first full-service human-composting funeral home in the United States is operational.

After nearly a decade of planning, research and fundraising — not to mention a successful campaign to change state law — Recompose is finally converting people into soil.

Outside, the entrance to Recompose looks like most of its neighbors — just another unit in a tall, almost block-sized building with plain metal siding and big, roll-up warehouse doors. But inside, it feels like an environmentalist’s version of a sleek, futuristic spaceship: spare, calm, utilitarian, with silvery ductwork above, a few soil-working tools (shovels, rakes, pitchforks) on racks, bags of tightly packaged straw neatly stacked on shelves, fern-green walls, potted plants of various sizes.

One immense object dominates the space, looking like an enormous fragment of white honeycomb. These are Recompose’s 10 “vessels,” each a hexagon enclosing a steel cylinder full of soil. One day in mid-January, eight decedents were already inside eight vessels, undergoing the process of natural organic reduction (NOR) or, more colloquially, human composting.
