Investigadors de la Universitat Polit\u00e8cnica de Catalunya – BarcelonaTech (UPC) participen en el projecte Quartz Enrichment Enabling Near-Zero Silicon (QUEEN), amb l\u2019objectiu de reduir la depend\u00e8ncia de la Uni\u00f3 Europea de fonts externes per a mat\u00e8ries primeres cr\u00edtiques, especialment del silici metal\u00b7l\u00fargic (MG-Si). Per aconseguir-ho, es proposa aprofitar un recurs poc explotat fins ara: la sorra de quars procedent de pedreres europees, amb la finalitat de produir MG-Si de manera local, sostenible i eficient.<\/h4>

El projecte aborda un repte significatiu: la forta depend\u00e8ncia de la UE de fonts externes per a mat\u00e8ries primeres cr\u00edtiques, especialment el silici metal\u00b7l\u00fargic (MG-Si). Actualment, m\u00e9s del 80% del MG-Si \u2014vital per a aplicacions d\u2019alta tecnologia i les ambicions de sostenibilitat de la UE\u2014 s\u2019importa principalment de la Xina.\u00a0

L\u2019objectiu global del projecte QUEEN<\/a>\u00a0\u00e9s crear un proc\u00e9s respectu\u00f3s amb el medi ambient per produir silici metal\u00b7l\u00fargic a partir de sorres de pedrera, amb emissions de CO\u2082 gaireb\u00e9 nul\u00b7les, i aprofitant materials residuals en el proc\u00e9s. Aquest enfocament transformador podria convertir qualsevol pedrera de quars de la UE en un potencial reservori de MG-Si. A m\u00e9s, les tecnologies desenvolupades podrien adaptar-se a altres materials.

Per aix\u00f2, es dissenyar\u00e0 un nou proc\u00e9s de separaci\u00f3 mineral basat en la flotaci\u00f3 en escuma amb reactius d\u2019origen sostenible per a l\u2019extracci\u00f3 de quars a partir de sorres de pedrera com alternativa m\u00e9s eficient i ecol\u00f2gica per al refinament de quars d\u2019alta puresa, i recuperar calcita i feldspats com a subproductes.

Per part de la UPC, els grups que hi participen s\u00f3n el Grup de Recerca en Mineria Sostenible (GREMS), coordinador del projecte, el Grup de Recerca en Recursos i Ind\u00fastries Intel\u00b7ligents i Sostenibles (RIIS), el Centre de Recerca Smart Sustainable Resources (SSR-UPC) i el Centre de Recerca en Supervisi\u00f3, Seguretat i Control Autom\u00e0tic (CS2AC-UPC). Tamb\u00e9 hi contribueixen l\u2019Institut Universitari de Recerca en Din\u00e0mica Fluvial i Enginyeria Hidrol\u00f2gica (FLUMEN), el Grup de Recerca en Sistemes TIC Intel\u00b7ligents i Segurs (SINAPSI), el Grup de Rob\u00f2tica de Serveis i Rob\u00f2tica Industrial \u2013 Operacions, Producci\u00f3 i Empresa (SIR-OPE) i el Grup de Rob\u00f2tica de Serveis i Rob\u00f2tica Industrial (SIR).

La UPC treballa principalment en el desenvolupament del nou proc\u00e9s de separaci\u00f3 i la seva validaci\u00f3 en el pilotatge, juntament amb socis industrials fabricants de reactius biol\u00f2gics per ser utilitzats en els processos. El valor del quars en el mercat va en funci\u00f3 de la seva puresa, i aquesta tecnologia hauria de permetre a les empreses l\u2019acc\u00e9s a mercats de m\u00e9s valor afegit.

Impacte<\/h4>

El projecte QUEEN t\u00e9 un fort impacte econ\u00f2mic, social i ambiental. El projecte t\u00e9 com a objectiu cobrir el 56 % de la demanda de MG-Si de la UE abans de l\u2019any 2032. A m\u00e9s de reduir la depend\u00e8ncia de les importacions, el projecte preveu recuperar m\u00e9s de 300 milions de tones de MG-Si a partir de sorres i estalviar 232 mil milions de tones de CO\u2082.

A m\u00e9s, el projecte contribuir\u00e0 a reduir en 714.000 tones la depend\u00e8ncia europea del quars importat, creant 440 nous llocs de treball i generant un increment estimat del benefici brut de 140 milions d\u2019euros.\u00a0

Des del punt de vista ambiental i tecnol\u00f2gic, el projecte busca millorar l\u2019efici\u00e8ncia en l\u2019\u00fas dels recursos en un 30% i establir nous est\u00e0ndards dins l\u2019estrat\u00e8gia europea de mat\u00e8ries primeres cr\u00edtiques.

Socis, pressupost i finan\u00e7ament<\/h4>

El projecte QUEEN compta tamb\u00e9 amb la col\u00b7laboraci\u00f3 de 14 socis procedents de 8 pa\u00efsos de la Uni\u00f3 Europea.

Finan\u00e7at en el marc del programa Horizon Europe, el projecte compta amb un pressupost total de 7.294.162,27 \u20ac i t\u00e9 una durada prevista de quatre anys (novembre de 2024 – octubre de 2028).
