What does Prime 6 make?

Prime 6 makes one material: high-purity biocarbon from hardwood residue. Steel and ferroalloy producers use it as a reductant in place of fossil coke. Growers put it in soil. Carbon buyers count it as durable storage. Industrial users can feed it to fuel processes. Each use gets its own specification and particle size from the same line, so the lab data is the same wherever it goes.

How does Prime 6 make it?

Prime 6 carbonizes hardwood residue from timber mills in closed chambers under a patented process, with no binders, glues or additives. Running the whole process in one plant, on one line, is what keeps fixed carbon, ash and moisture inside the published ranges lot after lot. Sizing happens on site, from fine powder to granules to hexagonal briquettes.

Why Prime 6 built a plant first

Many biocarbon suppliers a steel buyer meets are pilot plants without the capacity to supply for the long run. Prime 6 built the plant, took out the patents and put the lab data on the table before asking anyone to qualify the material.

Milestones

  • Prime 6 founded to turn hardwood residue into high-purity carbon
  • Three U.S. patents issued on the closed-chamber process
  • Ground broken on the Fairmont, West Virginia plant
  • Metallurgical biocarbon offered to steel and ferroalloy producers
