Construction waste is filling landfills. The construction and demolition industry has about double the amount of trash as all the other waste in cities, Fast Company reports. Companies are searching for nontraditional sources to eliminate some of that landfill waste and keep costs down.
Biohm, a biomanufacturing startup firm based in the United Kingdom, plans to start mass production of insulation made from mushrooms—actually their mycelium component, the thread-like roots that connect mushrooms. The company says biodegradable insulation outperforms the more common foam. It’s also slower to burn in a fire.
“Mycelium is usually found in forests, underground, and it holds the topsoil together,” Ehab Sayed, founder and director of innovation at Biohm, told the World Economic Forum in March. “It allows plants to connect to one another—it’s like nature’s internet. And we grow that into an insulation panel that can provide superior insulation values compared to other alternatives on the market.”
