Inventory Rebirth Chronicles – How 50K Circuit Boards Unlocked ¥1.2M Value

Client Profile:
A global Top 3 home appliance manufacturer faced rising warehousing costs (¥500,000 annually) and environmental compliance risks due to 50,000 obsolete smart AC control boards from product line upgrades.

Core Challenges:

• Lead-containing solder non-compliant with updated RoHS standards, incurring steep disposal fees
• Warehouse space occupied by obsolete inventory blocking new material storage
• Internal valuation showed <10% residual value, pushing management toward fire-sale liquidation

ChengYu’s Solution:

1. AI-Powered Grading
   Classified boards via smart inspection system:

   • Grade A (mild oxidation): 35% refurbished for Southeast Asian secondary markets
   • Grade B (salvageable components): Harvested premium capacitors/relays for industrial equipment maintenance
   • Grade C (end-of-life): Eco-extracted copper/gold through bioleaching

2. Cross-Border Circular Economy
   Built compliant recycling channels with Vietnam/Indonesia buyers, accelerating ROI to 45 days

Quantified Results:

• Total recovered value: ¥1.236 million (40% above client expectations)
• Freed 800㎡ warehouse space, reducing annual costs by 32%
• 100% eco-processing achieved, preventing 16 metric tons of e-waste landfilling
