ROI Calculation Logic

Manual bagworm silk collection typically requires 5 skilled workers, costing ~$200K/year (AI est.) in personnel, with an additional 20% of labor for impurity removal. This technology could reduce total manual labor and impurity removal by 50%, leading to annual personnel cost savings of ~$100K (AI est.) per facility. Additionally, higher purity could increase product unit prices and open new markets, generating over ~$0.5M/year (AI est.) in new revenue opportunities.

Speed to Market
4× faster than in-house development
This technology was developed by a national research institute, establishing a concrete technical solution for container design based on bagworm physiological characteristics. The mechanism for inducing bagworm silk extrusion has been verified, and the principle for collecting high-purity silk mass with minimal impurities has been demonstrated. This allows adopting companies to significantly shorten R&D periods from scratch and rapidly integrate the technology into existing bio-material production lines or new ventures. The basic research phase is complete, enabling early product commercialization and business development.
