ROI Calculation Logic

This technology could reduce high-purity BNNT manufacturing costs by ~67% compared to conventional methods. Assuming a market price of ~$6,700/kg (AI est.) and an annual production of 100kg, conventional annual manufacturing costs would be ~$670K (AI est.). Implementing this technology could reduce that to ~$220K (AI est.), yielding direct annual cost savings of ~$450K (AI est.). Including reductions in post-processing due to higher purity, improved yield, and a 3x increase in production capacity, the total economic impact could exceed ~$1.0M/year (AI est.).
