Mycelium in Construction
– Let us close-the-loop
In the race to find sustainable construction materials that will reduce our ecological footprint, new technologies from nature are paving the way. One of the newest and most promising is the mycelium brick formed from organic waste and the mycelium of fungus. These bricks can be used as a super strong, water, mould and fire resistant building material grown to your specifications. The technology reduces fabricating requirements. The architectural and construction industry have recently taken serious interest in them.
Construction applications for mycelium include a composite board (Myco-board) which can be used much like Medium-density fibreboard/particle board without the extremely dangerous formaldehyde used in the glue. Mycelium can be used to grow furniture and/or the bricks which are easily recycled at the end of their life. Depending on how the mycelium brick was made its compressive strength may be around 30 psi in comparison to the 4000 psi compressive strength of concrete. However, relative to its weight a mycelium brick is stronger than concrete with a cubic metre of mycelium brick weighing 43 kg and a cubic metre of concrete weighing 2400 kg.
More areas where people are developing applications for mycelium are Renovation, Restoration and building with mycelium wood, smart concrete, wall reinforcement material for restoration.
Benefits of Mycelium in Construction
The process of producing with mycelium brings a huge reduction in using fossil fuels. The energy required for fabrication is small and there is a massive reduction in construction waste as the product is 100 percent biodegradable and can be used as soil. Bio fabrication is a carbon neutral building process and can eliminate artificial insulation used in walls, use of particle board and other non load bearing structures. Mycelium products can provide other benefits such as termite proofing (it can attract termites but when eaten cause a fungus spore to activate within the termite killing it and creating a fungus whose spores repel other termites).
It is going to be hard to bring all the claims associated with Mycelium in construction to reality, but as one focuses on a project with Mycelium it is a good idea to investigate the claims both in literature and by testing on site.
The final result is a mushroom brick that can be 200,000 times softer than steel, 10,000 times less stiff than a typical housing brick, but capable of holding the equivalent of 50 cars.
When mycelium bricks are placed together, in a few hours, the material fuses together. The growth can be stopped when the substance is dried, creating a rigid material which can be sanded and painted. The mycelium bricks are bulletproof and absorb carbon dioxide, making them a sustainable material for the construction of our future buildings.
Weather-proofing them without destroying their essential “compostability” has been a concern. Natural oil has been used to penetrate into the bricks. They have been tested in a “home shower” and found to only gain a few percentage points of mass. “They don’t go really soggy and flexible,” says the fabricator, Ecovative.
“Perhaps the greatest potential of mycelium biocomposites is as an alternative insulation material for buildings. “Their biggest application in the long run is in architecture and construction,” said Dahmenm, assistant professor at U. British Columbia School of Architecture and Landscape Architecture . “The average age of commercial buildings in North America is under 40 years. If we could imagine construction materials that add positive value to ecosystems as they break down, we have a whole new paradigm for the way we approach buildings, at a time when we’re demolishing most buildings long before they wear out.”
Hy-Fi from The Living. “In 2014, we tested and refined a new low-energy biological building material, manufactured 10,000 compostable bricks, constructed a 13-meter-tall tower, hosted public cultural events for three months, disassembled the structure, composted the bricks, and returned the resulting soil to local community gardens. This successful experiment offers many possibilities for future construction.”
MOGU-Home products include resilient flooring, thermal insulating panels, acoustic absorbing panels, decorative tiles and engineered woods. The products use mycelium exclusively as a binding agent and can be formed into custom shapes or provided as flat boards. They are 100% natural fire-retardant and do not contain any toxic compounds.
MOGU-Home products will soon be available on the market. Their 2019 catalog of acoustical and flooring products is HERE.
“Our mission is to use the waste from various production chains to create new competitive products.”, says CEO, Mr. Stefano Babbini, “We are exiting from a pre-industrial phase. We are constantly approached by companies that have produced waste they wish to offer us in collaborations. We check whether these organic fibers are suitable for making composite materials.
Architect at work @Material Driven – Old Truman Brewery – London (UK) – Exhibition
Mogu materials and prototypes will be presented as part of Architect at Work, at the Old Truman Brewery (London – UK), in an exhibit about materials curated by Material Driven and The Building Centre. January, 2019
The architect Dirk Hebel (Karlsruhe Institute of Technology) and engineer Philippe Block (ETH Zürich), demonstrate the possibility to hold up a building or part of one with mycelium construction. The two established designers have created a self-supporting structure made entirely out of waste materials and bound with the fiber from mushroom mycelium. They are testing the potential of more sustainable building materials.
According to Hebel and Block, the material is strong enough to create a self-supporting two-storey building, if the structure is designed with the correct geometrical formations.
We used very tight calculations that exploit the strengths of the materials;
1. The fungal building blocks are able to withstand pressure and stabilise each other.
2. The weight and tensile strength of the bamboo lattice holds together the branches of the Tree.
The fungal building blocks for MycoTree were produced by an Indonesian company. Mycotech appears to be a forerunner of mycelium technology in the Far East. Originally a mushroom grower, it has joined the mycellium fabrication movement with a number of interesting products ready to market.
“The fungal building blocks look like pressboard. The only difference from normal pressboard is that fungal mycelium is the binder / adhesive,” says Heisel. “As far as we know, MycoTree is the first mycelium structure that supports itself as well as a load.” The project benefited from the know-how of Philippe Block from the Block Research Group (BRG) at ETH Zurich. Mr. Block has developed sophisticated graphic methods that enable statistics to calculate, construction properties of three-dimensional structures. It was possible to design a stable construction from a rather brittle material. “We wanted to show what is possible when the design is right,” says Heisel.
Another advantage is that the know-how for large-scale fungi production is already available from the food industry, from which the mycelium is just a waste product. That waste product can be put to good use in the construction industry on a regional basis.
Biocycler by redhouse architecture with Mycoterials
Every year, more than 530 million tons of construction and demolition waste like timber, concrete, and asphalt end up in landfills in the U.S. The firm redhouse, led by architect Christopher Maurer, has developed a biological process to turn wood scraps and other kinds of construction waste like sheathing, flooring, and organic insulation into a new, brick-like building material.
Bioterials™ produced from mycelium as a binder show results better than the compression of wood framing, the bend resistance of concrete, is a better insulator than fiberglass batts and has strong fire resistance. These and other biomaterials may have the capacity to revolutionize the building industry with better qualified materials while they lower carbon footprints.
redhouse studio was founded in 2014 in Cleveland, Ohio by Christopher Maurer. Mr. Maurer is an architect and adjunct professor of architecture at Kent State University. In practice, redhouse works in all areas of architecture, from research in low impact material technologies, design and fabrication, to net-zero retrofits. redhouse studio works closely with clients to innovate and design sustainable solutions built for a brighter future for all.
Panels and Blocks from MycoComposite™
Ecovative has developed a manufacturing system to grow large blocks of mycelium / wood composites. These can be cut, sanded, and used as ultra low density particle board panels or shaped into large forms. Perfect for a wide range of construction applications; door cores, acoustic panels and barriers, etc.
Ecovative is committed to working with industry and consumers to rid the world of toxic, unsustainable materials. We believe in creating products that enable companies and individuals to achieve their sustainability goals, without having to sacrifice on cost or performance.
