Redke zemlje in njihov vpliv na napredne tehnologije, mednarodno trgovino in logistiko : magistrsko deloKac, EditaRedke zemlje sodijo v skupino kemijskih elementov, ki zaradi svojih specifičnih lastnosti in ob upoštevanju vseh ekoloških standardov, izredno zahtevnega in dragega pridobivanja, predstavljajo temelj ... vsem naprednim tehnologijam. Brez njih si ne bi mogli predstavljati današnjega življenja. Nahajajo se v računalniških diskih, prenosnih telefonih, LCD-zaslonih, avtomobilskih baterijah, elektromotorjih ... Viri redkih zemelj so omejeni. Njihovo izkoriščanje je zaradi velike razpršenosti redkokje ekonomsko smiselno. Največji dobavitelj redkih zemelj je Kitajska, ki pa je obenem postala tudi njihov največji porabnik. S povečanim povpraševanjem so se pričele težave z dobavami. V letu 2011 je povpraševanje tako naraslo, da je preseglo ponudbo. Kitajska je zelo omejila izvoz in si s tem prislužila tožbo Svetovne trgovinske organizacije. Ostalim državam porabnicam redkih zemelj ni preostalo drugega kot nemudoma najti nove vire ali pa proizvodnjo preseliti na Kitajsko. Obstaja kar nekaj možnosti izkoriščanja novih virov, ki pa niso dosegljivi takoj. Potrebnih je kar nekaj let raziskav, da bodo novi viri primerni za izkoriščanje. Trenutno najbolj priročen vir in rešitev je recikliranje. Znanstveniki, tudi slovenski, na čelu z dr. Spomenko Kobe, pospešeno iščejo alternative redkim zemljam. Zaradi njihove velike pomembnosti v vrednostni verigi jih je evropska komisija uvrstila na seznam kritičnih surovin.Type of material - master thesis ; adult, seriousPublication and manufacture - Celje : [E.
