| Question | Answer |
|---|---|
| Another view of refuse | Avoid designs using materials which are harmful to environment or difficult to recycle |
| PET and PVC recylability | Difficult to differentiate but 1 PVC bottle makes a batch of 10000 PET bottles unusable Also PET absorbs contaminants so hard to make food safe again, so often is just used for fibres instead. |
| Polymer identification code | Dont indicate that its possible to recycle locally, just showing what polymer it is 7 being used too much with developments since the 1980s when the codes were introduced ID codes also starting for glass + metals |
| Recycling cars | Leverage on lawmakers by WEEE and End of Life Vehicles (ELV) crucial. Depollution process required and disposal of automobile shredder residue (ASR) Lithium batteries |
| The 'think' chair | Easily disassembled for material purity |
| Recycling overseas | Often unsafe - by children - toxins harming workers and locals. |
| Circuit board recycling | Easier to train service engineers to replace whole circuit board - not cost efficient to repair. Often sent for recycling for the gold, silver, and copper in ICs. |
| Repairing cars | Fibre reinforced polymer composites repaired not replaced + recycled like old sheet steel parts |
| WiTHiNTENT | Tonnes of unwanted tents after music festivals made into showerproof festival clothing - commercial scale upcycling |
| Integral fittings | Dont need tools. May need additional safety features in kids toys Can be separable or fixed for easy manufacture - fixed is a dilemma against 6 Rs |
| WRAP | Waste and Resources Action Programme. UK charity. Provides guides to manufacturers on durability and wear improvements, as well as repairability. |
| WRAP guidance | Instruction booklet availability, avoid weak points in case, vibration resistance, well placed ventilation/fans, reasonable duration of parts availability, prevention of water ingress, standardised spare parts across range, ease of access |
| Firmware | Need frequent updates for security issues and improved features, but could lead to hardware becoming prematurely obsolete. |
| Modular main beenfit | Easier to track and fault-find |
| Advanced soldering techniques | Wave or reflow |
| Fastest type of manufacture | Redistribution |
| Standardised parts | Easier manufacture if same parts between models |
| Other ease of manufacture | Adhesives, factory planning + layout simulation software, injection moulding, self finishing, moulded posts for self-tapping screws rather than complex, buying pre-made components |
| moulding texture into polymer surface | Add tactile, mask moulding blemishes, enhance aesthetics, simulate appearance of other materials |
| Smart material disassembly | Still in development. SMA and SMP (polymer) fastenings so that at end of life put into disassembly overs to reach transition temperature, leading to automatic or semi-automatic disassembly |
| Pen disassembly | Done by consumer, disposing of parts which cant be recycled and composting bio-polymer body in compost. 98% of pen can be recycled this wat, with some incorporating plant seeds for encouraging sustainability. |
| Aeron chair | 50% recycled materials and 90% recyclable |
