Agenda
+ the flow of today's presentation will follow the same flow as in the thesis

Problem:
+ humans using more material, more types
+ urbanisation and raising living standards
+ goals of - defossilisation and decarbonisation
+ PM supply strain + geopolitical challenge

Challenges with recycling of PMs
+ biggest - PMs are minority amidst base elements
+ price fluctuation - volatility
+ legislation targets - weight based
+ thermodynamics - theoretically yes but practically difficult to separate (energy & resource intensive)
+ stringent quality requirements while valorisation
+ scale of economy doesn't exist for PM


Aim/Objective
+ Widest: contribute to development of sustainable practices in metallurgy specifically electrified technologies
+ Wide: Investigations into the mechanisms of GDEx for optimisation 
+ 3 specific areas of focus being:
    1. 
    2.
    3.
+ While the scope focused on investigating the mass transfer dynamics of electrogenerated reductive species and the impact of key operational parameters on metal precipitation efficiency
+ detailed economic analysis, long-term environmental impact assessments, and the development of alternative electrochemical methods, were excluded from the scope of this research.
+ intricate mechanistic studies of gas-diffusion electrochemistry, the detailed design and scaling of flow-cell reactors, and the synthesis of nanoparticles for purposes beyond metal recovery were considered outside the scope of this work
+ long-term environmental impact, economic viability, or the full lifecycle analysis of the recovered materials
+ the development of new materials or technologies that could complement or enhance the GDEx process
+ Needed because: deliberately narrowing the focus to avoid an overly broad investigation & this focused approach facilitated a thorough exploration of the practical aspects and optimisation of the GDEx process



Appendices
+ GDEx at the intersection of several interesting research areas:
    -> gas-diffusion electrochemistry
    -> electrochemical engineering in flow-cell reactors
    -> metal recovery technologies
    -> functional material synthesis technologies

+ Production & Demand numbers (at least for Pt, Pd, W, V, Mo)
+ Waste sources - WEEE, PVs, catalysts, catalytic converters
+ Current PM recovery methods (OPTIONAL)
+ GDEx - superiority over conventional EC metal recovery methods
