BioVermiculite™ locks away more carbon than it emits, turning sustainable forestry
residues into soil solutions that fight climate change.
The crude ore is crushed and the raw Vermiculite is separated and sorted into size fractions, then sent to a natural gas dryer. The concentrate is transported by truck or train to the nearest ports and shipped to its destination. Upon arrival the material is transported to the expansion plant fed through a natural gas furnace fired by natural gas to exfoliate the material into its final form. The material is then packaged and shipped to its final destination. The production of vermiculite utilizes large quantities of natural gas and diesel fuel generating significant carbon positive emissions. Open pit mining incurs changes in land use.
The pine residue feedstock is collected and brought to the manufacturing facility where it is sized and sorted. This feedstock is heated to over 900 °C in an oxygen-free environment where the hemicellulose and cellulose vaporizes, leaving the underlying pine pore structure. This process also transforms the pine pores into a graphitic form that resists degradation in the soil. Otherwise the residuals would convert to CO₂ in a controlled burn or through soil microbiological respiration. The production of Bio-Vermiculite is carbon negative, locking down the carbon sequestered by the pine forest for centuries. Bio-Vermiculite does not contain Vermiculite.
For every ton of Bio-Vermiculite used as an amendment, approximately 3.5 metric tons of CO₂e are sequestered compared to conventional vermiculite. This makes Bio-Vermiculite a superior choice for sustainable agriculture and soil management practices worldwide.
Independent lifecycle data shows how traditional vermiculite contributes to emissions, while Bio-Vermiculite locks away carbon, delivering a net-negative footprint.
Summary at a glance
Same use—very different impact. Mined vermiculite adds carbon; BioVermiculite™ locks it away using upcycled forestry residues.
Net result: positive emissions from extraction, transport, and processing.
Net result: –3.5 tCO₂e per short ton vs conventional vermiculite.
Key takeaway: BioVermiculite™ delivers the same function with a net-negative carbon footprint.
