Suggested treatment of screens and monitors in emerging economies
| Examples for products covered | Screens, Televisions, LCD photo frames, Monitors, Laptops, Notebooks. |
| Specifics of this group | • Products contain CRTs and in small quantities LCDs
• Negative value (material value < treatment costs) |
| Hazardous components | • Fluorescent layer (carcinogenic) and lead glass (funnel) in CRTs
• Backlight lamps (most of them still contain Mercury) in LCDs |
| Suggested treatment | Manual dismantling
• Remove Back cover • Take out plastics, PWBs and cables • Remove CRT • Release the low pressure of CRT (danger of implosion) • Divide glasses • Clean panel glass (remove phosphor/fluorescent coating) |
| Productivity * | CRT-products: 150 – 300 tons per worker per year
LCD-products: 70 – 150 tons per worker per year |
| Minimum quantity (to establish profitable operations) * | 300 tons per year (2 worker) together with other input products |
| Start- up investment * | CRT-products: 20-25.000 € (working tables, compressor with pneumatic tools, safety clothes, gitterboxes, storage boxes, EHS training, special vacuum cleaner for fluorescent layer, …)
LCD-products: 15-20.000 € (working tables, compressor with pneumatic tools, safety clothes, gitterboxes, storage boxes, EHS training, …) |
| Potential next investments in technology when volumes increase * | For CRTs:
· Hot wire separation of panel and funnel glass Productivity: 25-40 pieces per hour or approx. 1.000-1.500 tons per shift per year Minimum quantity: 500 tons per year Investment: 20-30.000 €
· Cleaning of glass Productivity: approx. 800-1.200 tons per shift per year Minimum quantity: 500 tons per year Investment: 80-100.000 € |
