Electronic waste as mining ore
Consider product as an ore: Low amount of target material
relative to total Concentration is not sufficient:
• Total mass • Homogeneity • Dispersion • Impurity, contamination • Regulations • Ease of disassembly

CIRCULAR PRODUCT DESIGN • Enable multiple life-cycles
with minimal loss of quality and value
• Maximize remaining value
• Minimize required energy input
• Modular design for easy disassembly
• Create re-usable platforms
COLLABORATION • Cross value chains
• Cross business sectors
• Financial and Social Partners
REVERSE LOGISTICS • Enable efficient closed loops
• Collection of materials
• Legislation compliance
NEW BUSINESS MODELS • Service/Solution Delivery vs.
Asset Ownership
• Easy access and affordable prices
• From transactions to relationships

Recyclability: use end-of-life insights
Connections limit separation
14 Ruud Balkenende, TUD-IO, Circular Design Challenge, 10-6-2016
Observations
Fixed connections keep parts connected: screws, glue, potting
Relate design aspects to dismantling result: Recyclable materials Separable materials
15 Ruud Balkenende, TUD-IO, Circular Design Challenge, 10-6-2016
• Get PCB out in one piece ( smelting)
• Enable easy/fast detection of materials
• Use materials that can be recycled
• Use of compliant coatings
• Limit the number of different materials
• Avoid fixed connections
• Break-down (by shredding/disassembly) to
o Pieces with uniform composition
o Pieces of relatively large size (>1 cm)
materials
connections
electronics
Design Rules for Recycling not compromising performance or increasing cost
Design taking recycling into account

Aluminum parts fold, capturing PCBs
Sand potting prevents folding
Increase rigidness of structure in the case of ductile housing
