In a world where plastics and synthetical foams can outlive us in landfills and have prejudicious impacts on the surroundings , there are ways to confine such effects using something that ’s acquire all around us .
MycoBondTM biodegradeable packaging material, made from mushroom and agricultural waste, developed by Ecovative Design.
Fungal mycelium — the root - like filaments that mushroom spread out into soil to gather nutrients as part of nature ’s recycling organization — provide a naturally biodegradable resolution , indicate engineers Eben Bayer and Gavin McIntyre , the founders ofEcovative Design .
Five years ago , the duo produce their society based on a rotatory access that aims to rid the world of plastic and synthetic froth by substituting them with mycelium - based products .
Bayer and McIntyre plant Ecovative after adjudicate to search the possibilitiesfungal myceliumoffered as an industrial - grade resin . Bayer ab initio was catch by mycelium on a wage hike , and his interest grow in the structure ’s ability to bind together other constitutive materials into a foam - same structure .
The engineers , who at the clip were students at Rensselaer Polytechnic Institute in Troy , N.Y. , formulated a process for using mycelium to make a fabric that could be transform into desirable physique utile for packaging and other products . Once the stuff served its intended use , it could easy compost , seamlessly disappearing back into the environs .
The Binding Process
The manufacturing summons for the new froth — call MycoBondTM — begin with farm - source plant materials that are not suitable as either food or stock feed . The flora materials are cleaned and blended with other agricultural products , and then immunise with mycelium . Then come the revolutionary aspect — the product isgrown , in whatever shape the consumer needs , without any energy input . No gasolene , no light , no human interaction .
" Mycelium attachment operates under two different pathways , " say McIntyre . " First , the mycelium journey into pore that are neat than five microns in diameter , which allows for geographic expedition for nutrition . The second nerve tract necessitate thefunguscreating its own holes within the substratum using complex enzyme . The mycelium internet serves as a malleable cutis to hamper particles , or fibre , into a cohesive solid . "
At the factory , the material is placed in different mold and stack , and at the end of the process , the product is treated to prevent the growth of spore , and foreclose allergen concerns — a process evolve with the support of National Science Foundation small job grants . Within a workweek , the product is ready for consumption by the client .
Substrate and Fungus Specifications
The process is not limited by geographical availability of plant material or feedstock . Various agricultural byproduct can be used without a pearl in product carrying into action . Feedstock is sourced regionally : New York State has abundant oat hulls , Europe can utilise Fagopyrum esculentum and oats , and the southern United States and Asia are able-bodied to use Elmer Reizenstein hulls as the surface upon which the mycelium develop , also called a substratum . to boot , a product ’s lastingness is not dependent upon the substratum , but on the species and form of fungal mycelium that is used as the resin .
" By exchange the fungus , we can offer a product that will put down in just 30 years if put into a compost pile , or last for over 30 twelvemonth in an automotive program , " McIntyre said .
product
The lulu of growing material and tailoring them to meet consumer needs is that it allows for the production of a divers array of condition and products . For example , the company’sEcoCradlepackaging serves as a replacement for standard promotion materials . The client provides the engineering squad with eyeglasses , photos and the physical object being ship , and a usance EcoCradle is grown for each specific product . Once the customer has finished with the promotional material , it can be localise in a garden , compost pile or cubic yard thriftlessness and it will break - down safely because only benignant materials found in nature are used .

Since the merchandise entered the market , customers have include DELL , Steelcase and Puma . TheNational Oceanic and Atmospheric Administrationeven enlisted Ecovative to provide a protective , eco - friendly shield for some of its buoy other warning platforms , which will be placed in ocean to help warn coastal communities of impending tsunamis . The structural polymer present in the fungal cell rampart is chitin , which is also present in the shells of crustaceans ; this will start the buoys to stand firm harsh sea conditions for extended period of time .
Bayer and McIntyre are not stopping with protective packaging ; their mushroom based technology is now providing building mathematical product for commercial-grade and residential construction , as well . The production of standard insulant results in significant carbon dioxide emanation — Ecovative ’s insularism on the other deal , is grow , help increase zip efficiency in the home , uses no toxic chemicals and is a safe alternative . The MycoBondTM insulation has achieved a stratum 1 fervour rating and can also be bound to wood panel and used as structural insulation , set for roofing , as well as residential and commercial-grade building .
motorcar are include in the mushroom cloud makeovers , too . Various car role are made of foams and charge plate that are non - renewable and can release volatile organic compound , which admit a mixed bag of harmful chemicals with adverse health effects . Ecovative is working on creating specialized mushroom material that can be used in car voice , like bumpers , engine embayment , dashboard , and seats .
