Critical metals
Criticality is subjective, geo-specific and
changes through time.
One case study metal was palladium: Used in small quantities in mobile phones; potential
supply issues so may be “critical” in that regard
Market response through price, linked to
availability and demand; when price rises: Material substitution occurs
Closed mines re-open or new mining begins

Knowledge gaps
Where are the mobile phones going?
Where is the informal (electronics) recycling sector and how big is it?
Life cycle inventory data are incomplete
Wireless communication benefits versus improper disposal or recycling?
When mobile phones are discarded, what are the emission risks?
How small will future mobile phones be and what materials will they be made of?

Summary question (1)
What are the major material flows (in terms of environmental impact) and how are they
expected to evolve in the future? 1. Material flows cannot by themselves be used to
determine environmental impacts.
2. For impact assessment need additional SMM methodologies.
3. Life cycle inventory data for antimony and beryllium are currently unavailable (phasing out anyway)
4. The energy and GHG associated with the production of metals may be used as a first level surrogate for environmental impacts.

Summary question (2)
How can new insights be gained and translated
into new measures when taking a life cycle
perspective?
Need to understand the interactions and
dependencies within the design, production,
use, reuse and recovery life cycle stages to
facilitate:
Collaboration between recyclers and product
designers
Identification of material efficiency opportunities
Development of new measures or policies

One case study metal was palladium: Used in small quantities](https://reader033.vdocument.in/reader033/viewer/2022043017/5f39ce2360cea132d03cfbcd/html5/thumbnails/14.jpg)

Summary question (3)
What policy measures have been taken or can be taken to stimulate sustainable outcomes?
Many efforts are underway including: Corporate social responsibility (CSR)
Extended producer responsibility (EPR)
Integrated product policy (IPP), Cleaner Production
Eco-design, Eco-efficiency
Performance standards development
EPR for mobile phones Product capture rates will likely rise because of these
programs but need to engage the consumer by employing a different business model such as product leasing

Summary question (4)
To what extent have different actors in society
assumed active, ethically based responsibilities
for sustainable outcomes?
There are many international and domestic
initiatives underway: MPPI – manufacturer-based partnership promotes ESM
guidelines for end-of-life mobile phones
EPR for mobile devices is rolling out across Canada as
part of larger electronics EPR programs
A global inventory of stewardship programs for
mobile devices may address this question.
