ROI Calculation Logic

Assuming a waste treatment facility processes 50,000 tons annually, this technology could increase processing capacity by ~15%. This could lead to reduced outsourcing costs (estimated at ~$10/ton, AI est.) and increased revenue from methane gas sales (estimated at ~$50K/year, AI est.). Specifically, (50,000 tons × 15% × ~$10/ton) + ~$50K = ~$75K + ~$50K = ~$125K (AI est.). Including avoided opportunity costs from reduced fermenter downtime, the total economic impact is estimated at ~$150K/year (AI est.).
