From mouldy bread to athlete’s foot, fungi don’t exactly scream “home improvement.” But what if this misunderstood kingdom is the secret to the sustainable materials of the future?
Listener Alexis - definitely not a gnome - wants to know how much of our homes we could build with fungi. Professor Katie Field describes how the mushroom is the just tip of the iceberg - it’s the network of thread-like filaments called mycelium where fungi really do their best work. Architect Phil Ayers explains how fungi, like yeast in bread, can bind waste products into firm, MDF-like blocks. And while we’re not constructing skyscrapers with mushrooms just yet, it turns out fungi-based materials are already making waves in interior design. Think sound-absorbing wall panels or insulation that’s both eco-friendly and chic.
And here’s a cool one: mushroom leather! Using discarded stalks from mushroom farms, one company is crafting strong, flexible material for trainers, handbags, and even car dashboards. Move over, cows - mushrooms are pushing their way up.
Oh, and NASA? They’re dreaming big with fungi too - to grow habitats in space. From mould...to the moon!
