Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam tooj liab thoob ntiaj teb, qhov kev thov rau cov khoom siv raw yog maj mam nce, qhov kev tsis sib haum xeeb ntawm cov khoom siv thiab kev thov tau dhau los ua qhov tseem ceeb, cov khoom siv ore raw cov ntaub ntawv tau nruj thiab nruj, ntau thiab ntau cov lag luam yuav. hloov lawv cov xim mus rau cov tooj liab siv dua. Recycling tooj liab los ntawm tooj liab-muaj pov tseg thiab lwm yam khoom siv kom tau txais cov khoom siv tooj liab hu ua recycled tooj liab. Hauv kev tsim, ua thiab siv tooj liab thiab nws cov alloys hauv cov txheej txheem ntawm cov khoom pov tseg, cov khoom siv khib nyiab, cov khoom seem, cov khoom siv khib nyiab thiab cov khoom siv hauv tsev, thiab lwm yam, yog cov khoom siv tooj liab rov ua dua tshiab. Hauv cov tebchaws sab hnub poob, cov tooj liab rov ua dua tshiab (nrog rau kev siv ncaj qha ntawm lwm yam tooj liab) hauv tag nrho cov txiaj ntsig ntawm cov tooj liab ua kom zoo suav nrog cov feem ntau, ntawm cov uas, Fabkis, United Kingdom, Tsoom Fwv Teb Chaws Lub Tebchaws Yelemees thiab lwm yam yog ntau dua 40% , Ltalis yuav luag 100% ntawm cov tooj liab refined yog siv tooj liab.
