Eben Bayer and Gavin McIntyre, the founders of Ecovative Design, found inspiration while observing mushrooms growing on wood chips and how the mycelium – the ‘roots’ of the mushrooms – bonded the wood chips together. Mycelium, a fungal network of threadlike cells, then acts like a “natural, self-assembling glue”. This enabled the team to formulate a new method to produce materials able to replace various types of products, including petroleum-based expanded plastics and particle board made using carcinogenic formaldehyde.
The raw material used is agricultural feedstock. They use parts of plants that cannot be used for food or feed, therefore with low economic value. These are cleaned and inoculated with mushroom tissue. The mycelium grows in 5-7 days without needing any light or water, digesting the agricultural by-product and binding into the shape needed. At the end of the process, the material goes through a dehydration and heat treating process to stop the growth and to ensure the absence of spores or allergens.
This minimal processing reduces the cost of the product and thus enables its economic viability. Additionally, the technique can use multiple feedstocks, thus allowing Ecovative to use locally available crops. At the end of its use, the material can be simply composted at home without needing any special equipment.
In 2010, Ecovative commercially launched a portfolio of protective packaging products, originally called EcoCradle®. Steelcase, a global provider of office furniture, and Dell, the computer technology corporation, were early adopters. Since then, Ecovative has supplied their protective packaging to a growing number of other Fortune 500 companies. Ecovative is also investigating further applications, such as insulation, consumer products, and new bio-materials.
Since starting with two people 6 years ago, Ecovative has experienced very steep growth, reaching about 60-70 employees today, opening a new factory a year ago and planning additional plants in North America and Europe in the future.
