Designing out waste matrix template.
Thanks to ThingsCon 2018 and @mrchrisadams excellent talk on Reducing Carbon In the Digital Realm at Festival of Maintenance
| ThingsCon 2018 Designing out Waste Based on the MET Matrix from TU Delft Design Guide |
Extraction of Raw Materials | Design & Production | Packaging & Distribution | Use & Maintenance | End of life Disposal |
|---|---|---|---|---|---|
| Materials Material as an input mined, grown, harvested) |
What are the materials used? | What processes are used to make it? | What kind of packaging is used for the item and in transit? | What consumables are used by the product? What is needed to keep it working? |
Which bits can be recycled? Are their local recirculation schemes for them? |
| Energy Energy used in each stage as an input |
How much energy is used to get the materials you use? How did they get to the point of assembly? How far did they travel? |
How much energy does the manufacturing use? | How easy is it to transport? How does it travel? Where does it go? | How much power does it use? How much energy is used to clean and service it? | How much energy is used to treat the product or prepare for re-use? |
| Toxicity Emissions, effluent & waste as an output |
What are the waste products in extracting the material? Where do they go? |
What happens to the waste materials? How much is created? Can it be safely used elsewhere? Are their toxic emissions associated with Production Laser cutter emissions into outside street |
What is emitted by methods of transport? What happens to packaging afterwards? | Where do the consumables go after use? Is the product itself toxic to use over long periods? | Which bits cannot be recycled? What happens if the product is not treated correctly at end of life? |
