How It Works

Our Process

Agricultural waste is sourced from regional farmers.

The agricultural waste is cleaned and introduced to mycelium.

We create growth trays that we wash & re-use each week to grow new parts.

Loose particles are packed into the growth tray where the mycelium grows through and around the particles binding them together.

Parts are grown for 6 days and then removed from the growth tray.

Afterwards they go into the dryer and when they come out they are ready to ship to the customer.

Mushroom Materials are:

High performing

Cost competitive

Home compostable

Rapidly renewable

Custom designed and molded

Not derived from petroleum or food

Naturally fire resistant

VOC free


Fine-tunable to meet your needs

the mass of interwoven filamentous hyphae that forms especially the vegetative portion of the thallus of a fungus and is often submerged in another body (as of soil or organic matter or the tissues of a host)

Mushroom® Materials do not degrade without exposure to living organisms, such as that found in soil biota, and moisture. You can think of it like an unfinished piece of wood. A wooden table isn’t going to decompose without exposure to the right conditions. Like most things you’d keep in your home or in a warehouse, Mushroom Materials will last. But if you leave that wooden table outside, or put wood chips into a compost pile, it will naturally decompose. The same is true with Mushroom Materials.
