Follow the journey of hemp as it transforms from a carbon-capturing crop into permanent carbon storage in the built environment.
Carbon Capture
Hemp Cultivation
Industrial hemp grown on U.S. farms actively sequesters 10 tons of CO₂ per acre as it grows.
Fiber Extraction
Hurd Processing
Hemp stalks are processed to extract the hurd—the woody inner core used in our composites.
Manufacturing
Biofill™ Production
Hemp hurd is combined with our proprietary binder to create high-performance insulation.
Construction
Permanent Storage
Carbon is locked permanently into buildings, replacing fossil-fuel-based materials.
Measurable Impact
Carbon Captured & Stored
Every Biofill™ project represents real, measurable carbon removal— turning construction into climate action.

We're just getting started—join us in scaling carbon-negative construction.
Why Carbon Removal & Storage Matters
Carbon dioxide removal plays an indispensable role in combating climate change. By 2050, the IPCC estimates that at least 10 Gigatons of CO₂ need to be removed and stored every year. Construction materials offer one of the most scalable solutions for permanent carbon storage.
Additionality
Every pound of hemp hurd we use is carbon that would otherwise decompose and release CO₂ back into the atmosphere.
Permanent Storage
Carbon embedded in building materials stays locked away for the lifetime of the structure—often 50-100+ years.
Beyond Offsets
Unlike carbon credits, our materials create tangible carbon sinks within your supply chain and construction projects.
Verified Impact
Every project is measurable and traceable—we know exactly how much carbon is stored in each building.
The Bison Approach: Carbon Negative by Design
Hemp captures ~9 tons of CO₂ per acre during its growing season. When we transform hemp hurd into Biofill™ and embed it into buildings, we're not just reducing emissions—we're actively removing carbon from the atmosphere and storing it permanently. Every building becomes a carbon sink.
