Rooted in Appalachia. Built for Builders.
Turning Hemp Stalks into the
Materials of Tomorrow
GreenMatter partners with Appalachian hemp farmers to process stalk byproducts into high-quality fiber and hurd: sustainable raw materials for builders, manufacturers, and a stronger regional economy.
Whether you build with hemp or harvest it, we'd like to work with you.
Two Materials. Endless Applications.
Every hemp stalk contains two valuable raw materials hiding in the parts most growers throw away. We process them into forms that manufacturers and builders can put straight to work.
Hemp Fiber
Bast Fiber from the Outer Stalk
Long, strong fibers stripped from the outer bark of the hemp stalk. Naturally resistant to mold and UV degradation, with a tensile strength that rivals synthetic alternatives.
Applications
Hemp Hurd
Woody Core from the Inner Stalk
The lightweight, absorbent inner core of the hemp stalk. Naturally pest-resistant and highly insulative, hurd is the foundation material for hempcrete and a growing list of bio-based building products.
Applications
From Field to Factory Floor
We handle the messy middle so farmers can sell what they'd otherwise discard, and manufacturers get consistent, ready-to-use materials.
Appalachian Farmers
Regional hemp growers harvest flower and seed, leaving stalks behind. We purchase those stalks, giving farmers a new revenue stream from byproduct they couldn't sell before.
Collection & Transport
We coordinate harvest-window pickups across our partner farms in West Virginia and the surrounding Appalachian region, keeping logistics tight and costs fair.
Decortication & Processing
Stalks are mechanically separated into bast fiber and hurd, then cleaned, graded, and packaged to manufacturer specifications. No harsh chemicals.
Builders & Manufacturers
Construction companies, biocomposite producers, textile mills, and insulation manufacturers receive consistent, ready-to-use hemp materials at scale.

Good for the Soil. Good for the Economy.
Good for What Comes Next.
Hemp isn't just another crop. It actively regenerates the land it grows on and creates economic opportunity in the communities that need it most.
1.6t
CO₂ Sequestered per Ton
Hemp absorbs more carbon dioxide per acre than most commercial crops and stores it in the materials we produce.
Zero
Pesticides Required
Hemp naturally suppresses weeds and resists pests. It also restores nitrogen and breaks up compacted soil for the next crop.
100%
Biodegradable
Unlike fiberglass or synthetic insulation, hemp fiber and hurd decompose naturally at end of life. No microplastics. No landfill burden.
$$$
Potential Farmer Revenue
New income from a waste product, keeping dollars in Appalachian farming communities that have historically been left behind.
Every ton of hemp fiber that replaces fiberglass, and every hempcrete wall that replaces concrete, represents a measurable step toward decarbonizing the built environment while strengthening rural Appalachian economies.
Our Story
Built in West Virginia.
Driven by What We Saw.
We're Kassidy Blatt and Mason Cavalier, students at West Virginia University who grew up watching Appalachian communities search for new economic footholds as traditional industries shifted beneath them.
When we learned that hemp farmers in the region were growing a crop with enormous materials potential but had no reliable buyer for the most valuable part of the plant (the stalk), GreenMatter became obvious. Not as a theory, but as an answer to a gap we could see from where we stood.
We're building the processing infrastructure to turn those stalks into fiber and hurd that builders and manufacturers actually want. It's vertically integrated by necessity: the supply chain didn't exist, so we're creating it, from the farm gate to the factory floor.
GreenMatter was founded at West Virginia University and continues to grow out of the Appalachian region we're working to strengthen.
