Bio-based insulation and building materials (hemp, mycelium, straw)

Industry is the backbone of modern civilization, but it's also one of the biggest sources of greenhouse gas emissions. Manufacturing steel, cement, chemicals, and plastics doesn't just burn fossil fuels for energy — these processes often require fossil fuels as raw ingredients or release CO2 as an unavoidable part of the chemistry itself.

This creates a massive challenge. We can't simply swap in renewable electricity and call it solved. Heavy industry needs fundamentally different approaches: new chemistries, new materials, new ways of thinking about how we make things. The scale is enormous — industry accounts for about a quarter of global emissions — but so is the opportunity to transform how we build our world.

Every building, road, and bridge embeds enormous amounts of carbon in its materials before construction even begins. Making steel, concrete, aluminum, and glass releases massive amounts of CO2, and transporting heavy materials adds more emissions. This embodied carbon can account for 10-20% of a building's lifetime emissions, even before anyone turns on the lights.

As buildings become more energy-efficient, embodied carbon becomes a bigger share of their total impact. The construction industry is enormous — concrete alone is the most-used material on Earth after water — so changing how we build could dramatically reduce global emissions.

These materials replace energy-intensive insulation and building products with alternatives grown from plants or fungi. Hemp fiber, mushroom mycelium, and straw bales can provide excellent insulation while storing carbon. Mycelium can even be grown into specific shapes for building components. These materials are typically non-toxic, biodegradable, and have much lower embodied carbon than conventional alternatives like foam insulation or engineered lumber.
