– UL94 V-1: Some components
– Halogen-free: Growing requirement
– Additive: 15-25% loading

**EMI Shielding**:
– Conductive fillers: Carbon fiber, nickel
– Coating: Conductive paint
– Target: 60-80 dB attenuation
– Cost impact: +20-40%

**Aesthetic Requirements**:
– High gloss: PCR PC
– Matte finish: PCR ABS
– Color consistency: ΔE <1.0 - No visible defects ### E-Waste Recycling **Collection Systems**: - Retail take-back: Best Buy, Staples - Manufacturer programs: Apple, Dell - Municipal collection: 25% participation - Informal sector: Developing countries **Recycling Process**: 1. Collection and sorting 2. Dismantling 3. Plastic separation 4. Cleaning and grinding 5. Compounding 6. Quality testing **Challenges**: - Brominated flame retardants - Mixed polymer types - Metal contamination - Hazardous substances ### Circular Design **Design for Recycling**: - Material identification - Easy disassembly - Mono-material design - Avoid hazardous additives **Closed Loop**: - Manufacturer take-back - Refurbishment programs - Component reuse - Material recycling --- **Keywords**: recycled plastic electronics, e-waste recycling, circular economy, flame retardant, EMI shielding
