ROI Calculation Logic

Assuming a 15% improvement in PGM recovery. For a company processing 1 ton of PGM-containing waste annually, an additional 150 kg could be recovered. At an estimated market price of ~$2,000/kg (AI est.) for PGMs, this could eliminate the need to purchase ~$300K (AI est.) worth of new resources annually (150 kg × ~$2,000/kg). This directly translates to procurement cost reductions, potentially yielding multi-hundred-thousand-dollar economic benefits per year.

Speed to Market
6× faster than in-house development
