Technical maturity of various approaches to recycling and reuse of different materials is considered in Tables 1 and 2 below. These tables list the technology readiness levels (TRLs) for each material for various recycling technologies, as well the major sustainability issues, ranging from toxicology to material availability. A key for the tables is here at this link.

Use in electronics
Applications of the named material
Is the quantity of material used significant in absolute terms?
Potential recovery value (high/low)
If extracted through processes like recycling, does the quantity of material have significant commercial value?
Material availability considerations (y/n)
Is the primary extraction of the material confined to a limited number of regions globally?
Electronics use dominant (y/n)
Is the electronics industry the major user of the material or do other industries have a bigger share?
Responsible material extraction (y/n)
Are there issues around the primary extraction (e.g. mining, refining, etc.) of the material?
Are there legal requirements to report the use of the materials, for toxicological/environmental reasons?
