Contenuto audio
Il Coltan, insieme alle Terre Rare, è un materiale che ha contribuito in modo determinante allo sviluppo di computer efficienti, veloci, affidabili e con batterie sempre più durature. Inoltre, negli ultimi anni, ha trovato larga applicazione anche in altri settori strategici come l’industria aerospaziale e l'aeronautica tradizionale dove viene impiegato per fabbricare i motori dei jet oltre agli airbag, ai visori notturni, alle fibre ottiche.
Ma dove si estrae il Coltan e quali rischi ecologici si corrono? Risponderà a queste domande il professor Zarlenga, geologo, ricercatore Enea e autore di Geologia ambientale, principi e metodi. Ma Laser non si ferma qui... Come nel caso dei diamanti, anche per il coltan, è doveroso ricordare il prezzo “umano” che la sua estrazione comporta. A parlarcene sarà Pierre Kabeza, sindacalista congolese del Sud Kivu in esilio. Infine, alla luce di tutte queste informazioni, abbiamo chiesto all'economista Andrea di Stefano, direttore del Mensile “Valori”, una previsione di quanto il Coltan inciderà nell’industria dell’alta tecnologia nel prossimo futuro.
