ROI Calculation Logic

In organic solvent recovery and purification for pharmaceutical and fine chemical manufacturing, this technology could eliminate conventional distillation and multi-stage filtration, significantly reducing energy costs and processing time. For example, a company processing 100 tons of organic solvent annually could achieve a 20% reduction in processing time (saving labor and equipment operating costs) and a 5% reduction in solvent loss (saving raw material costs). This is estimated to result in over $200K/year (AI est.) in direct cost savings, based on reducing solvent recovery costs by 20% (~$35K/year (AI est.)) and solvent purchase costs by 5% (~$3.5M/year (AI est.)).

Speed to Market
4× faster than in-house development
This technology benefits from completed fundamental research at the university, with verified manufacturing processes for porous hydrophobic silica membranes and validated pervaporation principles, significantly reducing technical uncertainty. With licensing available, adopting companies can launch products or services much faster than developing from scratch.
