“The best design acknowledges that you can't disconnect the form from the material.
The material informs the form.”
“The only way to make the MacBook Pro unibody was to machine it from a single
piece of aluminium.”

“The use of aluminium…brings benefits in terms of:
• weight savings,
• improved fuel efficiency,
• lower emissions,
• increased crash safety, and...
• better vehicle dynamics”
“...the material of choice”

The industry must demonstrate that...
Dismantling of integrated value
chainIncreasing demand from customers for
responsibly sourced aluminium
1. it produces responsibly, by mitigating environmental impacts and positively impacting the communities in which it operates;
2. its products bring a net benefit to society in terms of reduced environmental impact; improved quality of life, health, safety & wellness and economic growth;
3. at the end of product life, the value of the metal, the energy that went into its production and the resource inputs are retained and realised as another product, through collection and recycling or energy recovery.

Vehicle light-weighting• 1 kg of aluminium, replacing heavier materials in a car or
light truck, can save 20 kg of CO2 over the vehicle life;• Similar number for electric vehicles in coal-intensive grids
such as India and China;
• Up to 80 kg CO2 per kg aluminium used in trains;
• The 20 million tonnes of aluminium shipped to the transportation sector every year could save half a billion tonnes of CO2 and over 100 billion litres of crude oil.

Three quarters of all aluminium ever produced is still in productive use

• A positive recycling story but…

CONCLUSIONS
![Page 37: THE ALUMINIUM STORY“The best design acknowledges that you can't disconnect the form from the material.

• 50% increase in semis demand from today;
• Increased recycling rates only offer limited potential, due to long life of products;
• Scrap quality also an issue;
• Primary aluminium will continue to meet the bulk of metal demand, at least until mid-century;
• 90 Mt primary required (65 Mt today).
2040 baseline scenario

Increasing risks• Raw materials supply and waste management;
• Significant range of greenhouse gas emissions, primarily a function of power mix;
• Location of new smelting capacity uncertain, but likely fossil fuelled power;
• Some companies are already marketing “low impact” aluminium in response to customer demands.
