RENW & Silvera Platform
Industrial platform architecture & operations at enterprise scale: thermodynamic physics moat modeling, unified shipping engine for 1K–100M units, piecewise volume discounts, multi-modal transport, geospatial port detection, EPR integration, 75+ SKU catalogue — production BI with Prometheus/Grafana.
Problem
Operating across platform-licensor (Silvera IP) and licensee (RENW) entities required a comprehensive decision and operations layer: first-principles thermodynamic models proving material parity against incumbent plastics, shipping calculations at enterprise scale, automated EPR compliance, and multi-facility capital allocation.
Business & Systems Impact
- Production systems powering commercial operations across operating (RENW) and IP holding (Silvera) entities
- Proprietary "physics moat": thermodynamic frameworks proving molded fiber parity against expanded polystyrene (EPS)
- 75+ SKU catalogue with real-time dynamic margin and pricing engines
- Enterprise scaling: piecewise linear interpolation across discount tiers (1K–100M units)
- Regulatory: EPR automation and public rulemaking testimony
- National expansion: financial proformas and site selection for multi-facility rollout
- 2,400+ lines of logistics and physics-oriented production code
