Mycelium is "part of the solution" to carbon-negative buildings

Mycelium could soon be used to insulate and fire-proof buildings while sequestering carbon, according to sustainability expert David Cheshire.The biomaterial, which forms the root systems of fungi, is "a fantastic thing," Cheshire said.
"It's naturally fire retardant," he said. "It's actually got better insulation properties than most standard insulation and it's actually sequestering carbon."
"It's grown on waste from the agriculture industry," he added. "What's not to like?"
