Rethinking the Environmental Cost of Burials
Modern burials often leave an invisible environmental burden, as traditional coffins rely on timber, metal and chemical varnishes that can linger in the soil for decades. Loop Biotech changes this narrative with a design that actively supports the environment rather than harming it. The Dutch startup created the Loop Living Cocoon, a biodegradable coffin made from mushroom mycelium and recycled hemp fibers, offering a natural alternative to conventional burial materials.
Growing a Coffin from Nature
Instead of manufacturing a coffin in a factory, Loop Biotech grows it. The company combines mycelium — the dense root network of fungi — with upcycled hemp fibers, and the mixture quickly forms a solid coffin-shaped structure in about seven days. Technicians then dry the material to pause its growth until burial. Once placed in the ground, the coffin begins breaking down within 30 to 45 days, and the mycelium actively accelerates the body’s return to the earth. As a result, the remains typically decompose within two to three years, far faster than in a traditional sealed casket.
Returning Nutrients to the Soil
This innovation does far more than simply disappear underground. As the mycelium breaks down, it releases nutrients into the soil and helps restore its natural balance. The coffin turns decomposition into regeneration, allowing the burial site to support plant growth and soil biodiversity rather than restricting it.
A New Philosophy of Final Rest
Loop Biotech’s creation invites people to see burial as an opportunity to give back to nature. By choosing a coffin that grows from the earth and returns to it, individuals can transform their final act into one of renewal. The mushroom coffin makes the end of life a beginning for the soil, completing a cycle that honors both the person and the planet.
