Our Process

From Farm to Form

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.

2030 Goal

Our Climate Commitment

We’re scaling production to make a meaningful dent in construction emissions.

150,000

tons of CO₂ removed

Current: 94 tons

Goal: 150,000 tons

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.

Why Our Supply Chain Matters

Every step is designed for sustainability, quality, and scalability.

Carbon Negative

Hemp sequesters more CO₂ during growth than is released during manufacturing and transport.

Domestic Supply

100% regionally sourced materials reduce logistical carbon emissions and support American agriculture.

Cost Competitive

Drop-in replacement for foam insulation with no retooling or new equipment required.

Partner Benefits

Manufacturers gain access to priority supply allocation and sustainability credentials.
