ð Case Study
Food Packaging Coating Line Waste Reduction Initiative
Unaccounted solvent waste and rework costs inflated reported unit cost by 12%
ðïļ Project Overview
High-speed aluminum can coating line in Texas
ðŊ Challenge
Unaccounted solvent waste and rework costs inflated reported unit cost by 12%
ð§ Design Approach
Mass balance modeling integrated with real-time VOC sensor data and coating thickness analytics
ð Design Diagram
AI-generated project design illustration
ð Key Calculations
Solvent Loss Cost per 1000 Cans
(VOC Emissions kg à $/kg Disposal) + (Lost Solvent à $/L)
Result: $41.72
Previously unallocated cost stream
Coating Thickness Variance Cost
(Std Dev Thickness à $/Ξm Excess) à Units
Result: $18.9K/month
Root cause: spray nozzle calibration drift
ð Results
22% reduction in solvent-related cost; $312K annual savings; coating consistency improved to Âą1.8Ξm (from Âą5.2Ξm)ðĄ Lessons Learned
- âĒEnvironmental compliance costs are production costs
- âĒProcess variability must be monetized, not just controlled
- âĒSensor-integrated models enable predictive cost intervention
â Key Takeaways
- 1Environmental compliance costs are production costs
- 2Process variability must be monetized, not just controlled
- 3Sensor-integrated models enable predictive cost intervention
