Dingfeng Closed-Loop Platinum Catalyst Recycling Program

The Business and Environmental Case for Recycling

Industrial catalysts containing platinum group metals (PGMs) — platinum, palladium, and rhodium — represent both a regulatory liability and a financial opportunity:

• 12–18% average PGM content in spent petroleum catalysts

• 300% price volatility in virgin PGM markets over the last 5 years

• 75% reduction in Scope 3 emissions when replacing mined PGMs with recycled metals

Dingfeng’s ISO 14001-certified process enables customers to realize substantial ESG and economic gains, supporting circular economy goals with confidence.

Technical Process Overview

Stage 1: Material Characterization

• Precision XRF and ICP-MS analysis to determine exact PGM content

• Hazardous material screening in compliance with the Basel Convention

Stage 2: Hydrometallurgical Extraction

• Proprietary lixiviant formulations (patent pending) tailored for catalyst types

• Counter-current decantation for optimized metal recovery

• On-site wastewater regeneration to ensure minimal environmental footprint

Stage 3: Metal Refining

• Electrowinning for high-efficiency PGM recovery

• Ion exchange systems to extract valuable rare earth elements

• Final product purity: 99.95%, compliant with ASTM B761 standards

Performance Benchmarks

• Revenue-sharing models to align incentives and reduce CAPEX burden

• Real-time tracking via secure customer portal

• ITAR-compliant handling for sensitive and defense-related materials
