Tallinna Tehnikaülikooli ja Tartu Ülikooli teadlased koostöös Ragn-Sells AS-i meeskonnaga on välja töötamas tööstuslikku tehnoloogiat põlevkivituhas leiduvate elementide eraldamiseks ja taaskasutamiseks Rootsis elluviidud sarnaste ringmajandusprojektide näitel. Suure jäätmesegmendi väärindamise teel taas materjalideringlusesse toomine on keskkonnasäästlikkuse seisukohast topelt kasulik, sest jäätmete hulka vähendatakse ja mitmete materjalide esmatootmist on võimalik seeläbi vähendada.
