DI:13.4 DESIGN FOR RECYCLING (DFR)
· When disassembling a product is can be very difficult to reclaim any value.
· There are three clear objectives when disassembling a product,
-
- remove subassemblies that can be resold as is.
-
- remove hazardous materials
-
- separate the remaining materials into single materials with as little effort as possible
· By following the design for assembly rules we can actually produce a part that is relatively easy to disassemble, and with some additional rules we can obtain easy to recycle designs.
· The basic rules (above DFA) are,
-
1. Use modules (consolidated parts) that can be removed and reused in other applications
-
2. Mark all materials for identification that cannot be sorted easily
-
3. Make parts easy to disassemble
-
4. Reduce materials and energy invested in the parts.
