MyForest Foods’s 78,000-square-foot vertical farm can grow three million pounds a year of mycelium, the root-like structure of mushrooms, to become alt-bacon.
If all living organisms on Earth evolved from a single cell 3.5 billion years ago, it stands to reason that they’re a lot alike. And, scientists have noted that fungi are characteristically even closer to animals than plants—which helps Eben Bayer, cofounder and CEO of MyForest Foods, argue that fungi are the better meat substitute. “Mycelium is basically an inside-out animal,” he says. “Mushrooms are quite fleshy, so they really have a lot of the characteristics that you find in an animal, unlike plants.”

The mycelium tech company will grow slabs of the mushroom material in its new 78,000-square-foot vertical farm in upstate New York—the world’s largest for mycelium, according to the company—where, for optimal growth, it keeps conditions precisely like a misty morning forest.

The company views alt-bacon as a significant gap in the alternative protein market, which it believes mycelium’s gristly texture can help fill. It aims to serve itsimitation baconto a million customers by 2024.
His evolutionary reasoning aside, Bayer notes how mushrooms have been delicacies for centuries. Throughout history, hobbyists (who he affectionately calls “weird mushroom people”) have foraged for fungi, and some gourmet species have long been fare in Michelin-star restaurants. But mushrooms are small, delicate, and intricate, possessing physical characteristics that haven’t lent themselves well to large-scale cultivation for replicating whole cuts of meat.
Before venturing into meat alternatives, Bayer was already immersed in mycelium production at an industrial scale: In 2007, he cofounded Ecovative, which produces mycelium as a material for packaging and clothing, replacing plastic and leather; MyForest Foods is an affiliate of Ecovative. (Other similar companies, like MycoWorks and Bolt Threads, have also turned mycelium into materials; the startup Meati is using mycelium for chicken and steak alternatives.)

And what we do [to them] is just awful.” Still, people crave bacon; theaverage American eats 51 slices a year. Even as some people are switching to Impossible Burgers and the like, many still can’t resist topping them with bacon. Burger King, in fact, recently debuted anImpossible Southwest Bacon Whopper, with real bacon.

The process actually starts a few feet from the vertical farm, in an agricultural silo (essentially a “big pressure cooker”) in which wood chips are swirled and heated up. What emerges is a “wet wood-chip slurry,” which will be the growth medium, like soil for a plant, into which they “dribble” the cells of the gourmet oyster mushroom. That resulting mixture transfers into various 100-by-3-foot beds.[Photo: MyForest Foods]The facility is similar to indoor farms now common forgrowing greens large scalein urban areas where crops are stacked like towers for space and efficiency—the biggest of which is a 330,000-square-footfacility in Dubai.As with those farms, the mycelia are kept at controlled conditions for optimal growth, including temperature, humidity, and CO2 level—but for fungi, the space is kept dark, foggy, and dewy, with a gentle breeze running through. By tweaking such micro-conditions, they can make sections of the slab denser than others, like a biological 3D printer. “That becomes the facsimile to what you’d see in an actual animal,” he says.

Bacon has a high carbon footprint, with a person’s yearly intake emitting 1,050 pounds of carbon equivalent, and causing water pollution from nitrogen runoff.
So far, MyBacon sells at retailers, including co-ops in New York State and Massachusetts. But Bayer wants to scale quickly, an ambition that will have assistance from a new partnership with Canadian organic mushroom farm Whitecrest Mushrooms, which will grow three million pounds of mycelium per year on less than one acre of land. And influential investors include the founder of Applegate Farms, a traditional meat company, illustrating the shift in attitudes toward meat alternatives.
Despite all the work to set up this facility, Bayer says the brunt of the effort was already done centuries ago—by our ancestors, who risked death to sample random mushrooms to survive. “They did the heavy lifting, and figured out the ones that are already very meat-like,” he says. “We’re just wrapping this amazing natural technology in a cyborg suit.”
