The Magical Mushroom Technology Behind the “Cocoon”

For the tricky business of breaking down biological remains, few contenders pull the weight of mushroom-based products. As we’ve recently covered in some detail, America has had its first mushroom-based burial used an imported vessel called “The Cocoon” from a company in the Netherlands called Loop Biotech. Though American products are available stateside, the attraction of Loop’s Cocoon lies in its established track record and rapidity of its decomp process, as well as its budget-friendliness. Here, we’ll take a look at a bit of the magic behind the Cocoon’s dispositional superpowers.

Like similar mycelial-based products, The Cocoon is fully biodegradable, entirely of cultivated mycelium and plant matter. The design incorporates a bed of moss as a lining and the entire burial vessel designed to fully break down in less than two months, enriching the soil. The fortified soil then accelerates decomposition of remains to less than 3 years (compare to the 8-10 typical with traditional burial).

Tools of the Mycelial Trade: How it works

The magic (lies in a process called Mycoremediation. Mycoremediation gains traction and effectiveness as the process is refined. Famously effective species include Pleurotus ostreatus (oyster mushrooms) from the family known as white rot fungus, which are particularly useful at environmental waste sites like oil spills and prized for the ability to break down hydrocarbons and toxins (like formaldehyde) by producing enzymes capable of dismantling complex molecules.

These fully green burial options pack a double punch: when activated, released enzymes break down organic matter more rapidly, while the mycelia neutralize many toxins present in the body. By dismantling potentially harmful molecules and rendering them inert, Mycoremediation intercepts heavy metals, microplastics, and pharmaceuticals, among other substances, protecting the surrounding soil from pollution that might otherwise leach into ground soil and surrounding water sources.

Loop’s Cocoon

The fungal species used in The Cocoon’s proprietary formula aren’t specified, but the company website indicates that they’re local to the region. The initial period of growth of the Cocoon vessel, during which it is shaped into a casket-type form, take about 7 days; after, its cured and dried to a shape solid enough to hold a grown man.

Last words

There are other Mycoremediation product options from Loop, of course, and similar businesses. Depending on the context and the wishes of the family, all work in similar ways. Options like Mycoremediation are among the most ecologically responsible available, and offer benefits to the environment in urban areas, especially cemeteries where soil quality is declining. For clients with an eye toward green funeral options, such mushroom products are sure to attract attention and gain popularity as the worldwide market expands.
