    "concept_summary": "Zeoform converts waste cellulose fibers (hemp, paper, cotton, etc.) and water into a microfiber pulp through high-energy grinding. The pulp is formed and dried, hardening without binders, chemicals, pressure or external adhesives. The resulting material can be lightweight or dense, comparable to hardwood, and can be shaped by spraying, moulding, pressing or machining.",
