Let's get back to nature with our final item on the list. We've talked about living walls, modular panels inside and outside of commercial buildings that contain live plants. We also touched on using plant materials like hemp and straw for insulation. But what if the very walls themselves were made of plant material? More than one journalist has compared mycoform technology to the Smurfs' mushroom houses and with good reason. This tech involves actually growing building materials using mycelium, a type of fungal spore.
Researchers have found that they could fill a form, such as a large block, with an agricultural product that would otherwise be waste material, such as buckwheat husks. The mycelium feed off the husks, growing to fill up the empty space in the form, and then it's heat-treated to kill the spore and stop its growth. The result is a strong, solid brick or plate of "mushroom" material, in whatever shape you want. They're inexpensive and require no toxic chemicals or a lot of energy to make. The downside is that they're also totally biodegradable, but if the molds for the bricks are made out of recycled aluminum, or the material is used as insulation between other non-biodegradable materials, you can avoid it breaking down. Unlike the other items on our list, this one is still in the experimental stages (although it's currently being used for packaging), but who knows what the future holds in green construction?
