In the first part of this blog I looked at the metals currently considered critical among sector analysts, and those that UK consultancy Oakdene Hollins has identified as likely to remain or become critical in the next five to 10 years.
The potential for strong price growth among these
Failure to advance metal recycling, especially of rare metals used in high-tech products, could produce a global shortage of many metals within two decades, according to a series of reports by the United Nations Environment Programme (UNEP).
With few exceptions, recycling rates have been modest or low, and in some cases non-existent, the report says.
At a news conference, Thomas Graedel, a member of UNEP’s International Panel for Sustainable Resource Management and a Yale University professor, cited the example of indium, a metal used to create transparent electrodes used in liquid crystal displays, touch screens, semiconductors, and photovoltaic cells.
Our high-tech products increasingly make use of rare metals, and mining those resources can have devastating environmental consequences. But if we block projects like the proposed Pebble Mine in Alaska, are we simply forcing mining activity to other parts of the world where protections may be far weaker?
Every time someone pushes the on-button on an electronic device, there is an expectation that the unit will power up quickly and display images in vibrant color. There is the further expectation, especially when using electronic devices for communications such as email access, web downloading, and texting that the response time will be immediate. We live in an age of technological arms races in which manufacturers gain market edge by creating products that are faster, have more applications, have a broader network reach, and generally do more.
The processing capacity of digital electronic devices doubles about every two years (Moore’s Law), and this capacity increase is enabled by an expanded use of elements. For example, computer chips made use of 11 major elements in the 1980s but now use about 60 (two-thirds of the periodic table!). And the electronics sector isn’t alone. Engine turbine blades for aircraft are made of alloys of a dozen or so metals; motors and batteries of green-technology hybrid vehicles depend on several of the rare earths; advances in medical imaging have come about by the unique band gaps of elements such as gadolinium. It seems that there are no limits to what the imagination can create except for the fact that many of the metals are globally rare and, given the nature of current technology, non-substitutable.
The recession is hitting recycling hard.
Markets for metals and other recyclable goods are in the toilet. Some haulers are even stockpiling stuff in hopes of better days ahead.
The downturn has put the future of National Recycling Coalition in jeopardy, according to a letter sent recently to members. Among the ideas being floated are consolidating the group with another similar organization.
In what is becoming a familiar refrain, the federal stimulus bill holds some promise. The bill includes a provision from the NRC and its members that authorizes $3.2 billion for the Energy Efficiency Block Grant program, for communities to use for energy-related actions including projects related to source reduction and recycling, the coalition says.
