Mining and extracting metals has ecologically damaging consequences.
Solar panels and electric cars come with their own environmental trade-offs like increased mining and extraction.
Aluminium is hugely useful, but energy-intensive to produce. What if we didn’t have to smelt any more?
Here’s how to quench your thirst in an environmentally responsible way.
There are many possible outcomes from the closure of the smelter – just don’t expect lower electricity prices to be one of them.

Resettlement plans for large infrastructure projects don’t always go according to plan.
Don’t forget your friends.

Canada rushed to counter a deadly lung disease afflicting gold miners in the early 20th century. The “quick fix” cure that was invented is a symbol of the lurch towards global industrialization.
Renewable resources are being exploited to the extent that there is a loss of species and future generations are threatened.
Proceed with caution when using foil for cooking.
While cooking food in aluminium pots isn’t a bad thing, doing so in foil is problematic. Over-exposure to aluminium may pose serious threats to human health.
Batteries can cut carbon emissions, but mining the metals and other resources needed to make them can be a dirty business.

The advent of battery storage heralds an even deeper embrace of electric cars and renewable energy. But amid the green tech revolution, we should be wary of creating new pollution problems.
Alcoa is to close its Point Henry smelter in Geelong.
Alcoa’s decision to close the Point Henry smelter, at a cost of almost 1000 jobs in Geelong and elsewhere, comes amid a perfect storm buffeting Australia’s aluminium industry. Point Henry will be the second…
The vast majority of us will never be exposed to aluminium in high enough concentrations to do damage.
Silvery, ductile, malleable and so very, very useful, aluminium is the most common metal in the Earth’s crust. But despite its importance (or perhaps because of it), there are fears that this metal causes…
Certain types of corn can grow in soil that would kill most plants. A genetic variation in certain strands of corn has meant…
Australian researchers are looking for ways to reduce the energy consumption of aluminium smelting.
The Australian aluminium industry is in the doldrums. A high dollar, low prices and Asian competition are threatening the industry, with older plants in New South Wales and Victoria under threat of closure…
With Alcoa reviewing its Geelong smelter, just what is the future for the aluminium industry?
The sight of molten metal pouring from a furnace has long been an iconic symbol of industrial might and wealth. In Australia, the metallurgical industries have provided long term jobs and wealth to many…
An international research team has discovered a new material, superdense aluminium, which has never before been seen on Earth…
