Ezinbestekoak dira guretzat. Lur arraroak deitzen ditugun metalak ezinbestekoak dira iman eta motore elektriko eraginkorrak egiteko, eta, besteak beste, energia berriztagarriak ustiatzeko behar ditugu. Baina, batetik, haien mehatzaritza kutsakorra da, eta, bestetik, geopolitikoki mendekotasun handia dugu beste herrialde batzuetatik ekarri behar ditugulako. Galdera da, birzikla daitezke? Tecnaliako Maider Garcia de Cortazar eta CEIT-eko Iñaki Diaz izan dira gurekin honetaz guztiaz hitz egiten. |
