`Is it practically possible to realize or not?!`

@On June18th, Honda (Motor Co. Ltd ) announced that they would reuse the rare earth used for the battery of a hybrid car(HV) to the motor of HV in cooperation with TDK (Co.)and some other companies.

Nikkei (Inc.) reported that Honda has been reusing the collected rare earth to the batteries as far and now they tried to extend the target of recycling.
This announcement is really interesting in all senses.
Honda announced it on the same day at the press conference about their action for the environment. The president Takanobu Ito particularly emphasized that Honda wanted to provide both a value of the environment called by for the society and a pleasure of driving the car.
The rare earth will be reused by 3 steps; 1. Hondafs domestic dealers collect Ni-MH(Nickel metal hydride) batteries from the HV. 2. JMC(Japan Metals &Chemicals Co.,Ltd.) takes out Nd(neodymium) of the rare earth which improve the magnetic force. 3. TDK processes it into the magnet for the motors of Hondafs cars.

In fact, The Ni-MH batteries has been reusing generally. But most of them are only a dry-type and amounts of its recycling is pretty small, even though Toyota (Motor Co.) extensively described in the CSR-report the flow of the reuse (extracting mish-metal from the hydrogen storage alloys and then using it for the rare earth of the batteries ) . Most of the used Ni-MH butteries are supposed to become a source of nickel as nickel alloy by the manufacturer of the special steel of stainless, because the recycling to the material of nickel is the most rational and the lowest cost way of it. There are high economic potential and also the benefits there. We may be well assured that all recycling canft circulate without the economic potential or its marketability.
I'm concerned the point of taking out the neodymium from the Ni-MH butteries.
The mish-metal contains cerium and lantern and also neodymium (The mish-metal of the Ni-MH butteries which Honda is using are Ni-Nd type contained neodymium quite a lot ) , but they originally are not for the batteries. In case that Honda tries to take out such a trace element and re-processes it to use for a magnet in spite of above the fact, (Even If neodymium is used for magnets, itfs absolutely necessary to separate neodymium and a samarium completely by the solvent extraction) I guess it is just a waste of time and cost and it doesn't have any business merit for Honda. Theyfd better to purchase and stock neodymium rather than reuse. Ifd like to ask Honda what kind of benefits they will get by doing it.

Recently, it is often reported about recycling of the rare earth. Many companies report exaggeratingly that they are working on the recycling of the rare earth (even though it was just a level of scientific experimentation). As a matter of fact, Ifm sure that they wonft carry out it positively because the recycling of the rare earth is not rational for the business.
Why donft the Nikkei try to report not only the recycling of the rare earth, but also fact that it doesnft exist?
