COMMON SENSE<br />
ON RARE EARTHS<br />
COMMENT<br />
Totally<br />
transforming...<br />
The current rare-earth crisis has been looming for several years.<br />
Observers have long warned of the danger of China becoming the<br />
dominant supplier of these materials, which we rely on for products<br />
ranging from televisions <strong>and</strong> headphones, to batteries <strong>and</strong> glass –<br />
<strong>and</strong>, of course, for the high-power magnets used in many motors.<br />
Despite their name, rare earths are not uncommon. An estimated<br />
64% of the world’s reserves lie outside China, but the Chinese have<br />
cornered the market by undercutting other producers, <strong>and</strong> by<br />
showing little apparent concern for the environmental impacts of the<br />
dirty business of extracting <strong>and</strong> producing the materials. Until<br />
recently, that is.<br />
China is now cutting back on rare-earth production <strong>and</strong> exports, as<br />
well as hiking their prices, citing a new-found concern for the<br />
environment as one of its reasons. It is also diverting more of what it<br />
does produce to its own manufacturers, thus adding value to the<br />
minerals, while restricting supplies to foreign competitors.<br />
Another possible motivation for China’s restrictions is that at, at the<br />
previous rate of production, China’s rare-earth resources could start<br />
to run out within 15 years.<br />
Not surprisingly, China is now trying to buy into rare-earth production<br />
facilities in other parts of the world. For example, it has attempted to<br />
acquire controlling stakes in at least two Australian rare-earth<br />
producers. One of these bids was blocked by the Australian<br />
government on grounds of national security.<br />
Although Japanese manufacturers have been hit hardest by China’s<br />
rare-earth restrictions, the effects are being felt around the world. In<br />
Europe, for example, the trade body that represents around 3,000<br />
suppliers to the automotive sector, has called on the European<br />
Commission to ensure secure supplies of rare earths <strong>and</strong> to look at<br />
possible production within Europe. For its part, the EC says it is<br />
“monitoring the situation closely”.<br />
If rare earths become unavailable or too expensive, there could be<br />
far-reaching repercussions. For example, unless alternative motor<br />
technologies can be commercialised rapidly, we will need to turn to<br />
bigger, heavier motors which could affect the efficiencies <strong>and</strong><br />
economics of road vehicles – especially electric <strong>and</strong> hybrid vehicles.<br />
The current rare-earth problems could last until around 2015 when<br />
new sources of supply are due to come on stream in several<br />
countries around the world. But some of the materials – such as<br />
neodymium, which is used widely in high-power magnets – could<br />
remain in short supply.<br />
The rare-earth crisis emphasises how dependent we are on key raw<br />
materials <strong>and</strong> how vital it is to have alternative sources of supply. We<br />
need to act globally to ensure that no single country or company can<br />
dominate the supply of such crucial materials in future.<br />
...your old drives <strong>and</strong> motors to new<br />
The ABB swappage scheme replaces<br />
your old worn out drives <strong>and</strong> motors<br />
from any manufacturer for new,<br />
highly effi<strong>cient</strong> <strong>and</strong> compact<br />
equivalents from ABB. Not only will you get at least 17.5 % off the list<br />
price but with the help of the ABB <strong>Drive</strong>s Alliance, <strong>and</strong> for a small<br />
additional charge, your new drives <strong>and</strong> motors can be installed,<br />
started-up <strong>and</strong> the old equipment removed for recycling.<br />
To discover how easy it is to swap your old for new<br />
visit www.drives.co.uk <strong>and</strong> click on the “swappage<br />
scheme” banner. Or simply call us on 07000 DRIVES<br />
