Asian sand smuggling-an environmental threat

It is getting a bit frightening to think how difficult the fight to conserve Earth’s endangered resources is getting. As the fight against global warming trends, inducing unthinkable global climatic patterns takes centrestage, one of our planet’s most fundamental resources — the ground that we walk upon is now being assaulted. Yes, exploitation of nature’s wealth has often been associated with deforestation and poaching but now a new dimension has been added in some Asian nations wherein sand is being illegally extracted to such an extent that the survivability of the existing biosphere is under severe threat. Sand Dredging seems to be setting new benchmarks for environmental mismanagement, since it is proving to be equally detrimental to both human and natural resources.

The Green Car Shocker

Hybrid Cars Could Soon Become ‘Extinct’ 

We have all heard about hybrid cars that are gaining worldwide acceptance as the more sensible and greener alternative to purely hydrocarbon fueled vehicles. The normal perception is that pricing is the biggest challenge when it comes to finding a substantial consumer base for hybrid engine powered vehicles. Surprisingly, a very different and disturbing reality has come to the fore — more than pricing, the constructional demand of a hybrid engine itself could be the reason for its early death. Not many folks know that the working of a hybrid car involves the use of trace quantities of minerals like lanthanum, neodymium, terbium, dysprosium and lanthanum. Called Rare Earth Metals, these elements are recovered through an extensive mining process and are very hard to find.

 

Just a handful of mining sites around the world can support the profitable mining of these elements. Before the hybrid car technology came into existence, their use was limited to making industrial magnets and batteries. Now, their demand is multiplying steadily as the sales figures for hybrid cars shows signs of constant growth. This has created a huge supply crunch, due to a simple lack of natural resources (i.e. rare earth metal mines) that can address this demand. The bottomline has already been predicted — if the hybrid carmakers cannot find another technology to fuel their green cars within the next 7 to 8 years, they push themselves precariously close to damaging the green car market beyond redemption.

 

Understanding Rare Earth Metal Demand among Hybrid Carmakers — the Toyota Example 

Global carmakers like Toyota and Honda have been gradually shifting towards making niche car engines that use the combined gasoline-electric technology. Toyota has already introduced its hybrid car in many continents and so far, the reviews have been very encouraging. Toyota’s prized possession in this niche called the Prius Hybrid has been a runaway success for its fuel efficiency, giving Toyota an overwhelming control over the US green car market. Nearly 70% of all such cars sold in the US are powered by Toyota patented engines. In fact, Toyota is in the process of somehow bringing this technology to mass volume markets like Southeast Asia wherein high-mileage cars seem like an obsession.

 

Hybrid engines present an irresistible option of saving upon fuel costs and benefiting from greater mileage. However, amidst the market-backed optimism, there is something bothering the R&D team at Toyota headquarters as it is becoming increasingly evident that the battery and electric motor combination is not very efficient when it comes to consuming rare earth metals.

 

Toyota officials might refuse to agree but there is a growing perception that the Prius is perhaps the biggest user of rare earth metals. The fact is that as the oil barrel costs continue to zoom beyond all comprehensions, even hybrid carmakers are bound to fight it out for raising the fuel economy of their cars. Already, the amount of neodymium being used in the hybrid version of Prius has been increasing with every recent update. Combined with heavy use of lanthanum, including more trace quantities of neodymium is useful for pumping-up the Prius’ fuel economy statistics.

 

So far, many environmental agencies have approached Toyota to seek an explanation as to how the company plans to restrain its dependency on rare elements that are being mined for its engines, but no substantial explanations have come forth. Now, it is strongly believed that instead of reconsidering its usage pattern of the rare metals, Toyota has gone ahead with finding more mining prospects in Canada and Vietnam to ensure that it maintains its monopoly in the hybrid, passenger car segment.

 

The Big Predicament 

It has been a difficult journey to sensitize the global audience towards cleaner energy sources like hybrid technology. Now, when the demand for cleaner cars is rising, the lack of rare metal resources could lead to a shortfall of more than 35,000 metric tons of hybrid ingredients in less than five years, i.e. around 2014. The global demand for rare metals is showing no signs of slowing down. The biggest predicament for green activists is that they don’t want to say anything that could dent the increasing demand for hybrid cars and negate years of effort that has gone into making hybrid cars a commercial success. However, any more delay in making people realize about this issue means harming the environment in a major way. Why?

 

The mining and related refining process for providing rare elements cannot adhere to the contemporary ecological standards if the demand trends continue to multiply at the current rate. Now, if the smaller industries are approached to reconsider their use rare earth metals in consumer electronics items, prices of these goods are bound to rise. This in itself is a major issue since endorsing a greener technology shouldn't come at the cost of hiking the prices of other consumer items, particularly at a time when recessionary trends are hammering every global economy. Even the new supply centers like the Mountain Pass of California will be able to support commercial mining after a few years, i.e. somewhere around 2012.

 

Current Demand/Supply Trends

Domestic Chinese industries continue to be overwhelming consumers of rare earth metals. China has been the world's largest rare earth metal producer for many decades. Rare earth metals produced from China alone account for 97% of the global production. However, China itself is responsible for consuming nearly 60% of the global annual production of these metals. China has now started to use rare metals in the production of low-priced wind turbines and energy-efficient lighting systems. These alternate energy solutions will definitely challenge the rare metal supply that is presently earmarked for hybrid engines. As a result, China is cutting back on the export of these metals, i.e. to address its own domestic demands. Further, just like the debated crude oil supply market mechanics, China is holding back its supply to make the global demand swell and hence, price for the merchandise rise.

 

Trying to Challenge China’s Monopoly 

Some other suppliers like Colorado’s Molycorp Minerals are desperately trying to challenge China’s domination in this segment. Molycorp plans to resume the extracting/refining that it had stopped a few decades back. California’s Mountain Pass mines had produced nearly 20,000 metric tons of rare oxides for some years, meeting the demand from the US market. Mountain Pass is regarded as the biggest reserve of rare elements outside China and once fully functional, it is capable of single handedly meeting US and European demands. The mining activity here is surging ahead and nearly 40 million metric tons of rare metal ores will be extracted in the coming years. There has been some buzz about the Canadian rare element sites around the Thor region but it is an unconfirmed site and its economic feasibility for long-term mining is still being analyzed. Lake

 

No Easy Solutions At Hand

It is heartbreaking to say that there are no easy solutions capable of solving the impending crisis. Some analysts believe that using a more efficient extraction/refining process that could ensure recovery of more useable compounds from the same pound of mineral ore may provide some relief. However, this means inducing more labor and as a result, the price of hybrid technology could rise. Things have just started to gain momentum in the annual global sales of hybrid engine-powered green cars and any price rise could halt this welcome development.

 

Exploring a new hybrid engine technology, that doest depend on rare earth metals means making substantial investments by carmakers. Considering the ongoing economic crisis and the limited growth for most passenger-car segments, this is not a favored option for most. Further, there are no affordable supplements to the rare compounds used in China’s volume-oriented electronics markets. If the world community is unable to find an immediately effective solution, hybrid cars will never find mass acceptance, challenging their effectiveness as a solution for substantially reducing dependence on fossil fuels or for controlling carbon emissions across the globe.
