Materials Energy Toxicity Matrix

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?
