Carbon-Negative Technology

The growing media component that actually removes carbon from the atmosphere

The Process Difference

Mining Icon Conventional Vermiculite & Perlite Mining

  • Source: Open-pit mining of finite mineral deposits
  • Extraction: Heavy machinery, blasting, excavation
  • Processing: High-temperature thermal expansion (850–1,000°C+)
  • Transport: Long-haul shipping; perlite largely imported from Greece and Turkey
  • Carbon Impact: Vermiculite +1.03 tCO₂e/ST  |  Perlite +0.47 tCO₂e/ST
  • Environmental Cost: Habitat destruction, finite resource depletion, no renewable pathway

Forestry Icon BioVermiculite™ Forestry Process

  • Source: Sustainably managed Pacific Northwest forest biomass (sawdust, bark waste)
  • Extraction: Efficient, low-impact collection from timber operations
  • Processing: Optimized thermal conversion (lower energy requirement)
  • Transport: Regional supply chain with minimal shipping distance
  • Carbon Impact: –2.50 tCO₂e per short ton (net negative)
  • Environmental Benefit: Upcycles waste, sequesters atmospheric carbon, fully renewable

–2.50 tCO₂e/ST

BioVermiculite™ Sequesters 2.50 Metric Tons of CO₂ Equivalent Per Ton

Carbon Intensity Comparison

Carbon intensity comparison chart

Conventional Vermiculite

+1.03 tCO₂e/ST

Open-pit mining, high-temperature expansion (1,000°C+), long-haul transport. A net carbon source.

Conventional Perlite

+0.47 tCO₂e/ST

Volcanic glass mining, thermal expansion (850°C+), largely imported from Greece and Turkey. A net carbon source.

BioVermiculite™

–2.50 tCO₂e/ST

Upcycled feedstock, efficient processing, regional supply chain. A net carbon sink — and a 1:1 drop-in for both.

BioVermiculite™ delivers the same function with a net-negative carbon footprint. Every ton permanently sequesters 2.50 metric tons of CO₂ equivalent — actively fighting climate change while improving plant performance.

Using BioVermiculite™ in Your Sustainability Reporting

Switching to BioVermiculite™ eliminates the carbon burden conventional vermiculite places on your Scope 3 inventory — at no additional cost, no credits to purchase, no contracts to sign. It comes with the product.

GHG Protocol — Scope 3 Category 1

The Burden You're Carrying Today

Every ton of conventional vermiculite adds +1.03 tCO₂e to your Scope 3 Category 1 inventory. Every ton of conventional perlite adds +0.47 tCO₂e. Both burdens come from mining finite mineral deposits, high-temperature thermal expansion, and long-haul transport — perlite largely imported from Greece and Turkey. These sit on your books whether you report them or not.

What Changes When You Switch

Up to 1.03 tCO₂e/ST — Gone. Included in the Price.

BioVermiculite™ is produced through a low-carbon process from sustainably managed forest biomass. Its Scope 3 Category 1 footprint is near zero. The moment you substitute BioVermiculite™ for vermiculite or perlite, that carbon burden disappears from your GHG inventory. No credits to buy. No offset contracts. It is simply the lower-carbon input.
