Hemp Hurd
Industrial hemp hurd — a high-cellulose core delivering strength, insulation, and sustainability across construction, composites, and ecological applications.
Hemp hurd (woody core) is a high-cellulose, low-density fraction with outstanding thermal and acoustic performance. Through precise decortication, grading, drying, and surface treatment, hurd becomes a scalable input for construction, insulation, biocomposites, absorbents, and soil-enhancing applications.
Processing Workflow
- SmartDecort: separation of stalk into fiber & hurd.
- Screening & Grading: sizing into coarse, medium, fine, micro.
- Drying & Conditioning: target 8–12% moisture.
- Dedusting & Cleaning: removing fines for consistency.
- Surface Treatment: mineral or bio-based fire/mold resistance.
- QA & Packaging: batch traceability & delivery.
